The Trump Climate Dump: Why It Doesn’t Matter if Even 100% of Scientists Agree on Global Warming

January 20th, 2017 by Roy W. Spencer, Ph. D.

Given current technologies, it makes no sense to destroy $100 Trillion in wealth this century for an unmeasurable reduction in warming.

Bjorn Lomborg.

Everything humans do requires energy. Everything.

The more efficiently we can do those things, the greater humanity prospers. Affordable energy is part of that efficiency.

But when human prosperity suffers, people die.

So, can it really be called “anti-science” that the moment Trump was inaugurated, the White House deleted all references to climate change on their web pages?

No, I don’t consider it anti-science. Because science has nothing to say about what it would cost in terms of human suffering to avert climate change. What to do about climate change is a matter of engineering and economics… not science.

As a lukewarmist I believe (but can’t prove) that humans are probably responsible for some of the recent warming (which has been mostly benign).

I further believe (but can’t prove) that humans will cause somewhat more warming in the future…. I’d put my best guess at maybe another 1 deg. C this century, based upon our (and others) research into climate sensitivity.

But until some new energy technology comes along (probably from the private sector) we are stuck with fossil fuels for the foreseeable future. The oil industry’s use of fracking has already reduced carbon dioxide emissions — through a switch from coal to natural gas — by more than any government command-and-control efforts.

As Bjorn Lomborg has recently estimated, efforts to “fight” global warming under the U.N.’s Paris Agreement could cost the world $100 Trillion in lost wealth by the end of this century.

That, I guarantee you, will lead to (preventable) deaths, due to poverty and all problems stemming from poverty.

And for what gain? An unmeasurable decrease in further warming of maybe 0.1 deg. C at best (and that’s assuming climate sensitivity is high and that we are in for several deg. C of future warming — which I don’t). As someone who knows how temperatures trends are measured on the ground (I’ll bet none of the thermometer climate data “experts” passed NWS weather observer certification exams like I did) and by satellite (I’m the co-inventor), I can say that this level of future temperature reduction is unmeasurable by any system we have.

So, while the White House deletion of “climate change” references from their website might be met with accusations that the new administration is anti-science, what I suspect it really means is that President Trump does not want to waste time and destroy prosperity just for those who want to feel good about their efforts to Save The World™.

Because the price for them feeling good might well mean the premature deaths of millions.

And that’s the way I would argue this issue. Poverty kills millions. As far as we know, human carbon dioxide emissions have killed no one. In fact, it has saved millions of lives and increased prosperity. For example, I’ve blogged before on the fact that more CO2 has increased corn crop productivity more than rising temperatures have hurt it, and that climate models have badly botched forecast warming post-1960 in the U.S. Corn Belt.

Eventually, we will probably run out of fossil fuels. We will probably have replacements before that ever happens, anyway. Those replacements will arise through market forces, not governmental fiat.

I don’t really care where our energy comes from. As long as those sources benefit humanity.

    Well said, Roy, I think it’s a hoot that the Obama climate propaganda site is gone.

    • Nate says:

      So which Lomborg is right, Roy’s or this one:

      https://www.theguardian.com/environment/2010/aug/30/bjorn-lomborg-climate-change-u-turn

      Lomborg argues here for spending $100B/y to combat climate change which he called ‘undoubtedly one of the chief concerns facing the world today’

      He advocates a carbon tax.

      It is quite confusing….

      • Robert Austin says:

        That article is dated 2010 and published in the Grauniad.It is now 2017. Perhaps Lomborg’s ideas have evolved.

        • Nate says:

          Yet after he wrote the Skeptical Environmentalist?

          • Prathyush says:

            I think Bjørn Lomborg position is quite clear he says a small amount of money into Research and development is sufficient in terms of “climate action”. No need to deploy expensive and unready technologies. If sensitivities are indeed on the higher side it makes sense to be prepared.

    • Nate says:

      The purge begins. Reminds me of other times in history when politically incorrect science and scientists were attacked and purged. In the nazi era it was ‘jewish physics’, which meant relativity and quantum mechanics. That continued until they needed ‘jewish physics’ for the bomb project.

      • No Fan But Can Respect says:

        I do not think that neither the Obama nor the Trump administrations are comparable to the Nazis, but if one must choose, I see more similarities between the Obama’s administration and the early actions of the Nazis. Skeptics lost their jobs under Obama. They were told not to apply for jobs. Other skeptics were reassigned and told not to participate in the discussion. Facts were distorted. Either ignorance or willful deception were behind many government proclamations and documents.
        We will see whether people lose their jobs under Trump. (I can see disagreements arising on whether loss of temporary or grant funding will be called loss of jobs.)

        Rather than the Nazis, I see a more applicable comparison to Lysenko science and the Obama administration. In Lysenkoism,the government said what the science was, and only supporters of Lysenko could get jobs or funding.

      • Nate says:

        I suspect it will start like it did in Florida, certain words will be banned, then firings happen:

        In Florida, officials ban term ‘climate change’ State environmental officials ordered not to use the terms climate change or global warming in any government communications, emails, or reports.

        http://www.miamiherald.com/news/state/florida/article12983720.html

      • Nate says:

        The difference is that ‘climate change’ is a legitimate science question, with much evidence to support it, and a need to do further investigation, similar to relativity and quantum mechanics in the 1930s.

        To halt investigation of it, for purely political reasons, is basically saying we dont need to know, we dont want to know.

        Can we agree that science is useful and ought not be politicized?

  2. FTOP says:

    Maybe that is why borrowing $9.5 Trillion in eight (8) years is nothing to worry about. Only $75,000 per taxpayer is a bargain compared to $100 Trillion.

    • It actually works out to about the same amount per year. People don’t realize how much our debt will hurt future prosperity. There are several ways to handle it, and economists tell me any one of them will be painful.

      • James W. Buell, Ph.D. says:

        ALL will be painful. Current interest rates are extraordinarily low, but will likely rise when the US economy comes off FED life-support. I haven’t done the math, but various economists have, and the “pain” will be staggering. Even a 4% growth from here for, say, 5-6 years won’t bring debt levels down from the very painful levels. Very sad and very irresponsible.

      • Nate says:

        Carbon tax could help tremendously with govt debt.

        • Robert Austin says:

          Look to the government to kill the golden goose. “Carbon” taxes are not free money.

          • Nate says:

            True. @ doe estimated $50/ton C, which is est cost of inaction, this adds 10 cents to a gal of gas. Big wup.

          • Robert Austin says:

            Nate,
            First, the “cost of inaction” is BS in that the reduction in CO2 emissions will have negligible effect on the climate.Secondly, unless your government returns the carbon tax windfall to the poor and low income citizens, the tax is regressive in that it hurts those people disproportionately.

          • Nate says:

            ‘reduction in CO2 emissions will have negligible effect on the climate.’

            Where do you guys get these nutty ideas?

            Sounds like you would never recommend calorie restriction– it will have a negligible effect on your weight.

            Also you are mimicking car manufacturers in the 70s regarding the Clean Air Act and air pollution.

            At the moment govt-revenue/gdp is lower than what it has been historically when the budget deficit was near 0 (e.g. in the late 90s). Taxes are a little to low. This is a problem that has to be fixed.

          • David Appell says:

            A carbon tax is the best market solution that we know of.

            James Hansen recommends giving all carbon taxes collected back to every American on an equal per capita basis. A yearly dividend check, much like Alaskans give an annual oil dividend (the Permanent Fund Dividend).

            An economic study calculated that 60% of Americans would get back more money than they paid in carbon taxes.

          • coturnix19 says:

            @davi appel

            A tax is not a market solution at all, so it can’t be ‘best market solution’. Something like a common law toxit torts would be though. ah, but that’d require actually proving, in a courts of law, the atual damage done. Nah, easier to subvert the government.

        • coturnix19 says:

          Neither the debt, nor deficits can possibly be shrank by rising taxes; rather, they are shrank by cutting taxes, as it is the only way to force govet to cut its spending. It is THE only way.

          • Nate says:

            Tax cuts. Been tried several times. Most recently under Bush. Pedictably it failed to lower the deficit.

          • Nate says:

            Tax increases were tried under clinton, and surprise, the budget balanced.

          • coturnix19 says:

            Needed more cuts then. Clinton didn’t contribute to his era prosperity, he just happened to be there (just as bush happened to rap the bust fruits of clinton’s boom)

          • Nate says:

            coturnix19,

            ‘Neither the debt, nor deficits can possibly be shrank by rising taxes, rather, they are shrank by cutting taxes’

            How about Kansas? Louisiana? They have substantially cut taxes. The miracle growth never materialized to save them and their deficits blew up.

            Does evidence matter?

          • coturnix19 says:

            does reading and understanding waht i said matter? i’d say no.

          • coturnix19 says:

            ‘Cause your argument is a strawman argument. Ok, let me explain my position in details (sorry for bad language, but i am a white trash uneducated b-tard with english as second language):

            The government, it works more or less like this:

            First, it plans to collect some amount in taxes, and it also plans to spend some amount for whatever purposes it deems necessary. If at some point in its spending spree it finds it doesn’t have enough funds, it doesn’t halt its activity, nor start cutting down on it and firing office people. No, what it does, is it borrows money, either from the market of from the central bank (which can simply print it, lending it into existence), often/usually by creating and selling bonds. And because the government *knows* that it can borrow money at any time, in reality it never plans to fit into the pre-determined budget. In fact this pattern of deficit spending spree planning is so ingrained now that the deficits are commonly planned ahead, and the spending budget is almost alway planned to be larger than the projected tax revenue.

            If at some point the revenue is more than had been planned, than that incentivises the government to spend more the next time. It is a natural, institutional incentive to do so as it spends money that’s not its own, and it runs debts that the officials are not in any way personally liable for. This incentive works at all levels, form parliament down to the smallest service office.

            Therefore it appears to me to be impossible, unless some special conditions are met, to reduce deficits not to mention the body of the debt, by raising ever more revenue. That is why i had said that raising more revenue will not help shrink the deficits. It may though make it look like as if the budget produces surpluses, as government agencies fail to anticipate to revenue and thus fail to spend it on time, but that is only a temporary situation that only makes the whole situation worse. That is what happened under clin-ton (and of course he personally had no virtue in making it happen, that goes without saying).

            Therefore, one can only see two ways to cut deficits, balance the budget and reduce the body of the debt (presuming one even wants to do it in the first place; some schools of though say that more debt is better, i think maybe chartalists think so). One way is an outstanding political will that can force the government to shrink its functions, but it is quite unusual to happen, but it does happen under special circumstances. That is how canada (temporarily) avoided the budget catastrophe in the 90s: they cut spending mercilessly: welfare, pensions, entitlements, bureaucrats; some say, rcmp even prepared for the riots of the disenfranchised welfare consumers and fired bureaucrats, but the riots never materialized. The other one is, if one lacks political will to impose voluntary draconian cuts, and bureaucracy lacks self-preservation (which almost always is the case), is to cut the funds available to the government for spending, by cutting taxes (not just for the rich, but across the board) big time. ONCE MORE, PAY ATTENTION RIGHT HERE! I explain for the kids with special needs: the goal of this policy is to choke the revenue flow into the government and force it to cut its spending, not to ‘unburden’ the taxpayer and the market – that comes as a extra benefit. And if as the result of the tax cuts the tax revenue rises – that is a failure of the policy, because the goal is to choke the revenue and force and force the government to decrease the spending, rather than to ‘cover the deficits’ with extra revenue as per supply side policy which, I assume, you assumed I had suggested. No, that’s not what i meant. That is why your complaint about the ‘kansas, louisianer’ is a misguided strawman argument as it assumes something i didn’t mean and didn’t say.

            Of course, this latter policy can only work if there is some kind of cp on the amount of money the government can possibly afford to borrow in a single year. that is the case with those governments in the world that don’t print their own money, such as state governments in the states, or governments of the countries lacking own central banks. Unfortunately, the us federal government is not of that kind, and its ability to borrow/print money is only limited by its ability to keep rates low without causing hyperinflation and/or run on the dollar. So perhaps, i was wrong all along: in the case of the us federal government, there is no practical way to restrain its spending and balance budget with any voluntary policy; only the run on a dollar will help. Touche…

          • Nate says:

            Not a strawman argument at all. I dont think you know what such a thing is. I presented to you cases (and there are more) where cutting taxes (with intent to cut spending) has failed to work in the real world.

            But, lets look at US govt revenue. It has basically been ~ 20% of GDP for several decades. Last few years it has been well below that. This despite the growth of health-care costs. Part of this was because of Bush tax cuts, part suspension of payroll tax after recession. Attempts have been made to cut spending-DOD, but much of it is health care related. So, inevitably the debt has ballooned.

            For me this is clear evidence that tax revenues need to be back near 20% of GDP, plus reform of health care and SS spending, to bring budget closer to balance. But the GOP has a one track mind when it comes to taxes: always cut.

    • David Appell says:

      Actually the public debt only increased by $8.1 T under Obama, and almost all that came to bail the country (well, the banks and corps) out from Bush JR’a disastrous Great Recession.

      Debt was up 127% in Obama’s first term, only 24% in his second.

      Don’t forget, Reagan tripled the debt.

        OMG Thank you David!!!!!!!

      • Job says:

        When you take 220 years of debt and double it four years (127%) and then only increase that number by 24% over the next four, that is because it’s hard to compound a parabola exponentially in a finite universe. It has nothing to do with economics.

      • Lewis says:

        David,

      • H.B. Schmidt says:

        Yeah, Reagan tripled the debt to bring us out of the stagflation that defined the Carter administration. Remind us all again what Reagan’s GDP was versus that of Obama’s?

        And the use of “only” when mentioning $8.1 TRILLION of debt under Obama should be viewed in the context that it’s more than all other presidents’ debt (through Dubya’s first term) combined.

        • David Appell says:

          And Obama accumulated debt to pull the country out of the worst depression since the 1930s.

        • jjmcmillin says:

          Let’s not forget the debt and war(s) the Bush administration left Obama and how Obama was able to pull the auto industry out of the ditch; the economy back on track and an increase in job creation on a monthly basis since before 2006; helped create a healthcare system for 50 million who prior to his administration had none. No question it needs tweeking, which now the GOP has for some ‘reason’ adopted a “repeal and replace” plan. Maybe killing bin Laden is not a current priority, but it certainly was for Bush/Cheney; only they weren’t able to pull it off in spite of billions spent on their war machine (Hallibuton, etc). Let’s not forget stopping the Iran build up to a nuclear weapons status.

          All that aside, no one has mentioned the fact that alternative energy industries create jobs (some specific, others not so much that will include a need for professional and nonprofessional) which will generate tax revenue. If people want to continue using their inefficient autos, at this point – or any point, 10 a gallon will not break anyone. For those whose income cannot manage it, exemptions can be made for even that.

          There will always be denyers on either side, but resolution can be reached to create workable solutions that can make sense to each. The conversation at least must continue.

          The answer is not denial, but conversation and action.

        • David Appell says:

          Labeling them “unfunded liabilities” is like labeling your mortgage an “unfunded liability.”

          But you assume you’ll have an continual income to pay our mortgage off.

          So will the US government have continual tax revenues to pay SS, Medicare, VA, etc.

          Your argument is nothing but a scare tactic, with no logic behind it.

          • Thomas says:

            So…..Dave, are you assuming the debt will be paid down by increased tax revenues or by reduced spending or is it some combination of each?

            Try diagramming the system and put things in motion…..That may
            provide a clue about how feedbacks in a system work…..Reduced spending will result in a reduction in tax receipts…..increased taxes will result in price increases (inflation) driving spending higher. But, ahhh, how’s about a massive Treasury default on outstanding debt to wipe the slate clean? Of course if you happen to be the “owner” of any of the debt either via mutual funds or direct ownership of Treasury notes and bonds you may not be too happy about having your “nest egg” be made to disappear.

          • David Appell says:

            I don’t assume anything but revenue, but I don’t think the federal debt will ever be paid off. Inflation will work to reduce it, but federal deficits will keep adding to it. The US will simply carry the debt.

            I don’t think it will be paid — there’s no real demand for that, and politicans always to give budget surpluses back to some group or the other, usually the rich — nor do I think it’s something that has to be repaid.

          • David Appell says:

            Thomas, PS: The US Treasury can’t ever default, because the US controls its own currency and can always print more money. Not ideal, certainly, but a default just won’t happen — way too risky.

      • No Fan But Can Respect says:

        David, I can see how you come up with your figures, but it seems a dishonest display. You give FY 2009 to Bush instead of to Obama. That is the wrong choice for two reasons. First, the conventional method was to give Fiscal years to the current president — until Obama supporters wanted a different story. Second, most of the deficit in FY 2009 was not for expenditures but rather investment in Preferred Stock in banks. That investment — plus more — was paid back by the banks to the government and reduced Obama’s deficits in future years.

      • Jala Painter says:

        The recession started under the Clinton administration even though it had benefited from being able to pretend Gingrich’s Contract with america was their own policy…and they had benefit from the tech bubble that was a bust for the bush administration.

        The Clinton Administration Social[ist] engineering was also responsible for the GFC as Clinton mandated the dodgy mortgages to people with no jobs…no income…no ability to maintain payments…the administration even sending organisers out to intimidate bankers who resisted..often in their homes.

        Those worthless mortgages were the foundation for the dodgy securities that the Clinton-enabled megabanks packaged and dispatched around the world.

        The megabanks were only made possible when the Clinton Administration with Rubin as Treasury Secretary repealed Glass Steagall which was to have prevented such catastrophes as followed.

        Before the ink was dry on the repeal, Rubin was off to join Citibank on a massive salary and the securities boondoggle was on.

        It was the Democrats ..not the Republicans who were gung ho for making squillions out of mortgage-backed securities that were without a reliable …or any… payment stream.

        When George W’s administration saw the danger and tried to rein it in, Barney Frank and other Democrats sneered and ridiculed them and blocked any mitigation.The Democrats were also allegedly the biggest snouts in the trough of Fannie Mae and Freddie Mac.

        That disaster drags the world down still today and it could not have happened without Clinton’s Social Engineering.

        What will be the cost of Obama’s precipitate withdrawal of troops from Iraq and his timidity and obvious lack of courage and resolve that has emboldened ISIS , Assad and Russia..four years ago he sneered at and ridiculed Romney for saying Russia was a threat…now he has made that existing threat exponentially worse.

            Jim Dean,

            Seriously, for every time you can find a video on the internet that presents a partisan viewpoint on an issue, particularly such a complex one as the financial crisis, there are 5 other videos that present the opposite viewpoint.

            When looking at such videos I recommend:
            1) consider the source: is it partisan or not? Does it have an agenda or not?
            2) Find an alternative source of info and check the facts.
            3) Are facts/stats being cherry-picked in order to convince you?

            The fact is blame can be assigned to many for the financial crisis. Deregulation was pushed by both parties but is a hallmark of repubs.

            Ultimately greed and unethical behavior on part of mortgage companies, wall street, and ratings agencies was to blame. Lax regulation helped.

          Self preservation played a role in the Sub-Prime mortgage market. As usual, when Da Guberment gets involved, business as usual is no longer workable. The attached was written by a member of the Financial Crisis Inquiry Commission, appointed by Congress to investigate the 2008 Financial Crisis. http://www.theatlantic.com/business/archive/2011/12/hey-barney-frank-the-government-did-cause-the-housing-crisis/249903/

          Just look at our screwy tax system. Everyone I know, do everything they can to pay minimal amount in taxes. Such as: Figure their own taxes, Hire a “tax Expert”, Hire a Tax Lawyer to find loop holes, the rich keep money overseas to avoid paying taxes. Regardless, the middle class always gets squeezed. The middle class can’t afford a tax lawyer, they don’t get “Earned” income credit like the poor, so they get burdened with making up for the what the rich and the poor don’t pay.

          Enough, I could go on for hours. I learned to listen to people that are intimately involved in their respective professions, like Roy Spencer, to help shape my understanding. People are at their best when the government does the least.

          • Nate says:

            Ok indeed, what you are showing me is what one member of the committee felt. In fact he wrote a dissenting view from the main report which is here:

            https://fcic.law.stanford.edu/report

            Most of the committee disagreed with him. Many others who’ve analyzed it and written about it disagree with him.

            There is strong evidence that mostly private Mortgage companies, like Countrywide, practically gave away mortgages, often with no-docs, and variable-interest rates (thank Reagan for that one) that were very likely to go into default. This ramped-up between esp. 2004-2006, apparently overseas investors had lots of money to invest and Wall Street packaged these into funds and this pushed banks to make more and more bad loans. This led to the boom and bust as interest rates went up.

            I see you make a habit of aligning with dissenters (like Roy). That’s ok, but just understand, that many, many, in fact most other experts disagree with them.

            Again your choice, but I wonder if the issue involved your kid with a serious medical issue, would you go with the dissenting doctor?

          • Nate says:

            And this author also wrote in 2004,

            Study after study have shown that Fannie Mae and Freddie Mac, despite full-throated claims about trillion-dollar commitments and the like, have failed to lead the private market in assisting the development and financing of affordable housing.

            This quite opposite to what he is saying above about Fannie and Freddie in 2010, as discussed here:

            Hi Nate,

            I appreciate your polite and analytical discourse. Several comments you’ve made compelled me look a little deeper into some assumptions I’d come to believe. I appreciate your candor and willingness to listen to opposing positions. A few other commenters on this blog aren’t as cordial.

            There were circumstances in our family (My Uncle on my Dad’s side) that made this more of an emotional situation for me. My Uncle was a banker that had protesters follow him home and harass his wife and kids to the point that he quit his banking position and became an insurance agent.

            It was a miserable time for his family and it affected all of us as we watched his family go through the move and job change. The government’s involvement hurt as many as it helped. Both political parties are at fault.

      Feelings and beliefs matter little and ought to be set aside when doing science.

      • Henk van der Wilt says:

        Yes correct. Feelings and beliefs do little, however the belief and arrogance that comes with these scientists thinking they can fix the climate is just unreal!! They can’t even get the records accurately recorded. Data is “Fixed” so that this data now support the hypotheses they stated. The money wasted in all these policies, and all that based on JUNK science!!

  4. Curious George says:

    It is amazing how fast the same people can switch from a danger of global cooling to a danger of global warming. They may have been mistaken yesterday, but they are surely right today – never mind that they were surely right yesterday. Such is the power of consensus.

    • matt rooke says:

      The shift you are referring to never occurred. It is a myth promoted by those who want to undermine the scientific process for political reasons. There were studies in the 1970’s looking into the effects of particulates on climate (hint, they cool) and also into the effects of CO2 (it warms). There was some scientific debate as to which effect was stronger but as climate science advanced (and our air became cleaner, thanks EPA) the consensus began to grow that global temps were on their way up.

      • Alistair Riddoch says:

        I personally am aware of over 20 theories attempting to explain gravity. And at least five models describing how the “fabric of reality” might work. I am aware of serious level theoretcial physicists thinking there may be no particles anywhere and that all things may be waves. I am aware of serious level theoretical physicists that declare this mathematically impossible, because were such the case, the sun would not work. would give off it’s heat and become a frozen ball almost instantly. I am aware of other serious level theoretical physicists that say, the latter must alsmost certainly be true.

        Science?? Really? That is the field used to promote the concept that humanity is catastrophically changing the Earth’s energy budget. I call foul.

        Anyone who wants to claim science is there justification for taxing all, to feed their fears, should at least then be able to identify what it is they consider to be the correct science. They should be able to choose a “fabric of reality” and then prepare to defend their choice. They should be able also to identify which they consider the proper explanation for the existence and operation of gravity, and then prepare to defend their choice.

        Only then should they go prancing around the globe spouting “science” “science” “science”.

        But alas. Instead, what we have is a bunch of wankers who don’t actually know actual science, spouting the reflection of their inner fears, and their inner loathing of others.

        They hold up an apple and let go. Look they exclaim, there is a “force” and it grps the apple and “pulls” it to the ground.

        Then they hold up a plate of glass and assert, “this let’s all the light through, but catches some on it’s way back, that is how the entire Earth’s atmosphere works, and that is science”.

        Meanwhile the atmosphere puffs and settles, the volume in constant flux, the energy allowed to dissipate this way and that.

        Science.

        Pah. Insert sigh of disgust.

        What science exactly is this of, which you speak?

        Do you have the ability to identify the pillars of that which you hold up?

        • David Appell says:

          The science of the enhanced greenhouse effect is very old by now and is based on extremely well-established physical laws, like the S-B Law and the spectra of molecules.

          The theories you mentioned are all at the very cutting edge of research and having nothing like the observational and theoretical backing that anthropogenic climate change does.

          BTW, the theories you listed are trying to explain more than just gravity. For gravity, Einstein’s general relativity has never failed an experimental or observational test. It’s even needed to keep GPS satellites accurate.

          • Alistair Riddoch says:

            that would be all fine and dandy if we could assume the atmosphere was a fixed volume container. gravity is the assumed provision of the nature of the volume of said container.

            to date, we have no ability and do not track the size of the container.

            heat is not heat without pressure. volume is a direct part of the heat/pressure/energy equation. lose control of knowledge of the volume, you lose control of any dampening or moderating effect that may be included in volume fluctuation.

            the assumption that we understand gravity is blown out of the water by unexplainable (currently), fluctuations in earth’s gravitational constant, although the measurement seem loosely coupled to some activity within the sun, but this is not even close to confirmed by any stretch of the imagination.

            einstein doesn’t enter the equation it applies to celestial bodies, and even then, fails to properly predict the movement of galactic arms and contraction and expansion of different areas of the universe, thus the perceived need to backfill the einstein vision of the universe with dark matter and dark energy at a ratio of 1 to 19. hmmm

            it is well known that quantum mechanics as accepted and confirmed to how ever many decimal places (8 I think), doesn’t just fail to explain gravity, but rather didn’t even attempt the effort. thus the many many theories in an effort to do so.

            what we are left with, is a bunch of hypothesis. none the favourite. scientists with varying opinions of what the “fabric of reality” looks like, how it operates, leaving open the doors for multiple infused dimensions, time travel, things that are there and not there at the same time, vacuum catastrophes, and a whack of physically observable phenomena with no reasonable explanation.

            if the “science” of the church of climatology were actually so “settled”, it sure seems to me, that the underlying science should be close to settled. and it’s mathematics identifiable.

            the above set of potential theories taking shots at how things might “really work”, are mathematically disparate.

            and again, at the least, isn’t it fair, to expect those asserting all others need donate their hard earned tax dollars, at least be willing to PICK ONE, and say,

            “As WELL as believing CO2 is warming the planet, THIS is how we believe physics works, and this is the math we use in our assumptions”.

            Or are those of us who are skeptical of the assertions of the alarmists, just supposed to say, sure, you can’t actually identify which mathematical model you use in your assumptions, but go ahead and tax us anyways”.

            well, that doesn’t sit OK with me. at the very least, the onus should be on the alarmists to fully disclose which assumptions they use in their SO CALLED “science”.

            my tax dollars are not so easily given to people who based on their emotions, and their FAITH, wish to assert that oil users are evil, and those promoting windmills and solar cells, are the good guys, and that only oil producers can be greedy and self interested, but that all windmill and solar cell investers only have the good of the planet in mind.

            meanwhile, the earth greens, the major ice sheets are doing fine, agriculture is on a year after year record breaking incline, and at least the US is enjoying a hurricane drought, not more frequent and nastier hurricanes. sea level rise, is almost non-existent in some places, and is partially explainable by what may be expansion due to some warming that could as easily be natural, since the slope of increase is not statistically different than the slope of increase during the 20s and 30s.

            there is very very obviously bias in the climate research and algoreithmic data adjustments, potential skewing of measurements due to expansion of urban development in some areas, but yet alarmists wish to dismiss satellite based collection as non-consequential.

            if you google “predictions of apocalypse”, you will find a list of over 200 predictions of mankinds demise. ALL wrong.

            what makes the current alarmists necessarily less wrong?

            it sure isn’t their understanding of gravity and the fabric of space-time.

            does actual void exist? do particles of substantial and persistent nature exist? are we a 2D projection of some sort?

            Maybe we have an impact on the climate. Do I accept that we know enough to properly assess such to necessarily be the case.

            who instigated the climate concerns. the US two years after an oil crisis that showed them the temporarily weak spot they had in their economy. hmmm.

            are the bulk of the US administration and policies based on christian values, anyone who watched todays inauguration would have to answer YES to that one. and every christian is brought up brainwashed to believe Man’s Sins = Global Flooding. talk about reruns.

            So. Wanna put my country in debt. Further enlave my kids to a future of perpetual payment of interest on debt because we didn’t do our due diligence. then I suggest you better, at the least, the very least, be transparent. you want to claim “well established science”, OK, I’ll bite….

            All I say is SHOW ME THE SCIENCE. Not observation, I don’t require that. Not hockey sticks. JUST the science you alarmists wish to propose is the underpinning of your justification for alarm.

            That would shut me up.

            But assertions that you are doing “science”, not making observations and guesses, well they won’t cut it, unless you can say, THIS IT THE MATH WE BASE OUR SCIENCE UPON.

            and I haven’t even bothered to point out that the current “all known physics” equation includes “i”, the square root of -1, a number that is not real. imaginary.

            well, maybe I went farther and said more than needed.

            perhaps, OK, you wish to say science, I only ask to SEE it. ALL of it. is that a fair request, before I allow the alarmists to stick their hands in my wallets.

            cause so far as I have seen, there is NO actual, hard, confirmed science to act as the foundation.

            how is mass made again? how much do neutrinos weigh again? how does time work exactly?

            hmmmmmmm

          • Alistair Riddoch says:

            Sorry David Appell, I over answered, and ranted a fair bit. my apologies. I really meant…

            Science, fine, show me which. that’s all. just be transparent and up front. nothing else was necessary.

          • Gordon Robertson says:

            “The science of the enhanced greenhouse effect is very old by now and is based on extremely well-established physical laws, like the S-B Law and the spectra of molecules”.

            It was first proposed by Arrhenius as the scribblings on his lunch bag and it was disproved back then, over a century ago. The greenhouse effect is a metaphor for a process no one has ever successfully described. The extended GHE is an extended metaphor.

            The basis of AGW is wrong. The fundamental theory is that solar energy heats the soil in a greenhouse and the soil radiated IR which is trapped by glass. That is nonsense and was disproved by Woods circa 1909. He built mini greenhouses, one with glass and the other with halite, which freely passes IR. Both houses heated to essentially the same temperature. Woods concluded a greenhouse warms due to a lack of convection. Same with a car with windows closed in hot weather.

            The atmosphere is rife with convective currents. There is absolutely no reason why GHGs should act as a roof on a greenhouse and to claim they trap heat reveals a complete misunderstanding of what heat is. Heat is a property of atoms and to trap heat, you need to trap atoms, as does the glass in a greenhouse. There is no mechanism in the atmosphere to trap atoms.

          • Lewis says:

            Gordon,

            I often wondered about the miracle of glass and greenhouses.
            It always seemed to me the point of glass, or any clear material, is to let sunlight in, not insulate from outgo of energy. Otherwise it would be better to build in an insulated building and use electrical lights.

            With modern materials, one could probably use the new thermal panes and improve insulating ability, but your point about convection seems to be most important.

            One has to agree, however, that gasses can inhibit the outflow of energy. Cloudy nights and days for example.

            The question then remains, can the increase of CO2, in parts per million, and a small portion relative to H2O vapor, make so much difference?

            I tend to follow Dr. Spencer on that: Maybe and probably but not much.

            And, MUCH MORE IMPORTANTLY, the good outweighs the bad.

            “…the assumption that we understand gravity is blown out of the water by unexplainable (currently), fluctuations in earths gravitational constant”

            The warming by heat-trapping gases in the air is now known as the greenhouse effect, but this is a misnomer. The air inside a garden greenhouse is heated because it is enclosed, preventing the circulation of air currents that would carry away heat and cool the interior.

            By the way water vapor causes 90% of the “greenhouse effect” if you insist on using fake terms.

          • David Appell says:

            Everyone knows the Earth does not literally have glass surrounding it.

            It’s a metaphor. A pretty good one, actually.

            BTW, water vapor in certainly important to the baseline greenhouse effect. (CO2 is too.) But not to the increase in the greenhouse effect. The amount of water vapor in the atmosphere depends on it temperature, and doesnt change in the temp changes.

            But as the temperature is changing, water vapor is too, and this has been studied and documented. It’s a strong positive feedbak.

    • FTOP says:

      He who controls the past, controls the future. The tactics of Phil Jones, Bill Connelly and the rest of the Climategate conspirators is right out of “1984”

      A 2009 investigative report from UKs Telegraph detailed the extent of dictatorial-like powers Connolley possessed at Wikipedia, allowing him to remove inconvenient scientific information that didnt conform to his point of view.

      All told, Connolley created or rewrote 5,428 unique Wikipedia articles. His control over Wikipedia was greater still, however, through the role he obtained at Wikipedia as a website administrator, which allowed him to act with virtual impunity. When Connolley didnt like the subject of a certain article, he removed it more than 500 articles of various descriptions disappeared at his hand. When he disapproved of the arguments that others were making, he often had them barred over 2,000 Wikipedia contributors who ran afoul of him found themselves blocked from making further contributions. Acolytes whose writing conformed to Connolleys global warming views, in contrast, were rewarded with Wikipedias blessings. In these ways, Connolley turned Wikipedia into the missionary wing of the global warming movement.

      After eviscerating references to 1970s global cooling scare and the warmer-than-now Medieval Warm Period from Wikipedia, and after personally rewriting the Wikipedia commentaries on the greenhouse effect to impute a central, dominant role for CO2, Connolley went on to team up with two other authors to publish a consensus manifesto in 2008 that claimed to expose the 1970s global cooling scare as a myth, as something that never really happened.

      • David Appell says:

        There was no consensus on global cooling in the ’60s and ’70s. Unlike today, it was a time before satellites were routinely provide loads of observational data, and scientists were not very sure what was going on. A literature survey of that time found there was no cooling consensus:

          ‘Notice there has been no significant net warming in North China since about 1950, consistent with the temperature trends for the Northern Hemisphere in general and similar to the identified pattern in reconstructions of Total Solar Irradiance.’

          Here is an actual graph of solar activity and N. Hemisphere temperature since 1950. http://tinyurl.com/gs4r9zh

      Recent heating in Artic during the winter proves the ability of adjusting temperatures and gives small harm to few.

      • Henk van der Wilt says:

        Isn’t it science’s job to explain that the excess heat from the El Nino time period is distributed to the poles for it be dissipated there? I am sure that the job of the ice at the south pole is to melt as a result of the excess heat energy transferred there by the ocean currents. Isn’t this why global temperatures started to drop so dramatically in the second half of 2016? Record ice melt (Speed and extent)at the the antarctic ice shelf is directly related to the extent of the dropping global temperatures in the latter half of 2016. So I am sure that the extreme heat brought to the Arctic in November and again in December served as purpose to help lower global temperatures.

        Funny thing tough is that CO2 is not dropping, quite the opposite.

        • David Appell says:

          ENSOs are a natural part of the climate system. They always will be, with others. There are more climate factors than just CO2 — natural factors STILL EXIT — and basing a statement about climate change on 6 or 9 colder months is very unscientific.

          Temperatures also dropped after the 1997-98 El Nino. Look how much higher those dropping temperatures are after the recent El Nino — they’re about 0.4 C higher.

    It seems from this post that some of your scientific skepticism comes from a belief that a transition to a carbon-free energy economy will be costly in terms of broad prosperity. I am an engineer (not an economist or a scientist) and from my perspective, a shift to move our economy to be less carbon-intensive (and let’s not forget methane) has great potential to BOOST productivity and ELEVATE people from poverty. In short, you are basing your skepticism on a very debatable point. Sure, if we were tomorrow to stop using all fossil fuels, of course, it would ruin our economy and send many into poverty. However, even a very aggressive move towards renewables and efficiency, done in a sensible way (say, through a gradually ramping carbon tax) could be a boon to the economy on a broad scale. Here’s the thing, the current fossil economy is necessarily controlled by, and profited from, a small number of huge corporations. Many of the solutions to move us to a low-carbon economy are on a smaller scale: energy efficiency, residential solar, technology start-ups aimed at all sorts of sharing/resource reuse. Any short-term costs in higher energy prices could be offset and more by a broader distribution of economic benefits. Plus, we are already at the point where solar and wind are quite competitive. Sure, we could put oil and coal back on top by cutting environmental regulation, but at what cost? Pollution and the majority of the burden of climate change are hitting the poorest hardest. A broader deployment of energy resources (and increase in efficiency) will provide more stability in the market. Fossil fuel energy costs have historically swung wildy, these swings are what can be disruptive, if not deadly, for people around the world who spend a significant part of their income on energy. I’ve seen it first-hand internationally. A new energy economy will provide more broadly distributed benefits and more stability. It will lift people out of poverty and prevent the potential for terribly disruptive climate effects on the poor. I hope you can take the time to re-examine your suppositions. I follow your blog because I want to expose myself to differing opinions and I trust that you are sincere in your desire to see science be unbound from politics and to see it be deployed in service of all; if you read this whole message, thanks.

    • John Moore says:

      I too am an engineer, but I know a bit of economics.

      The free market does a pretty good job in signalling that which is best economically and what is the most economically efficient. In that sense, the market acts as an ecology driving evolution of technology and business modes.

      So, if moving to renewable energy is good, then the free market should be selecting for it, without any subsidies.

      I suggest that we remove all subsidies from alternative energy except some R&D funds. We should also get rid of the many unnecessary barriers to the use of new generation nuclear power.

      Then, let’s sit back and see what evolves naturally. It might be nukes, solar might win (if and only if the intermittency problem is solved by *economical* storage), or natural gas CCGT might continue to win.

      • mothcatcher says:

        Exactly right, John Moore.

        The degree of warming provoked by human CO2 can be argued about, but not only are the disaster scenarios built on the shakiest of foundations, but our ability to reduce temperature rise – and reduce those disasters, if they turn out be be real, is very close to nil. This is what Lomborg has been saying quite effectively for a couple of decades.

        And there aren’t many examples of a good outcome when the Government thinks it knows better than the market. Much of human political history is a chronicle of this. Yes, it can sometimes nudge the market in a different direction, but even that has big downsides and such moves require both great wisdom and cast-iron justification. Both are demonstrably lacking in the CAGW area.

        This is wrong, because of negative externalities.

        Right now, fossil fuel producers and users get to pollute for free.

        The cost of the effects of that pollution are passed on to the country’s entire citizenry to deal with. For CO2 the costs are passed on to the next 4,000 generations, who must pay for the reprecussions.

We should only tax foodstuff 4 to 8% in lieu of oil companies. Darn it.

        Subsidies have been used for a long time to help develop and expand technology that is in the national interest. Nuclear power, oil and gas exploration, ethanol, now LED lighting.

Now these clean energy sources are competitive with dirty sources like coal that have demonstrated health effects.

      Not debatable at all. The data on this site reveals essentially no true warming for 18 years and 15 of those years between 1998 and 2012 has been confirmed by the IPCC. Such a lengthy warming hiatus proves beyond a doubt that GHGs have nothing to do with warming.

      The proposed carbon taxes are punitive, aimed at forcing people to use less fossil fuels. Canadian Prime Minister Trudeau is having Town Hall meetings in which he allows people in various areas to give input. One woman stood up and claimed her power bill now exceeds her mortgage.

      That’s the kind of nonsense being proposed by climate alarmists. Even here in BC, where we generate our power via hydro-electric dams, the cost of electrical power exceeds the cost of natural gas. Governments are out of control with the way they gouge consumers for power.

      It has nothing to do with science, warming or climate, it’s about ways to gouge people for more taxes.

The effect on the economy, and the global poor in particular, of transitioning to low-carbon is what I was saying is very debatable.

      Sticking strictly to C based reductions the cost is negative meaning it is a positive result to do nothing.

      The reasons are fairly straightforward:

      a) the proposed reductions would be insignificant in T terms to achieve anything (and even more so if one considers where most of the T increase has and is supposed to occur).

      b) doing nothing avoids the cost of economic change which will be of the order of at least 2% of GDP (ongoing) if a tax or impost or imposed productivity loss is to have any significant effect on CO2 reduction until some other more productive energy source is found.

      c) the net benefit of extra CO2 in improving agricultural output (and with less water use).

      Perhaps we should penalize those who wish to deprive us of the benefits of extra CO2.

    Great post Roy, any chance you or anyone here can explain (perhaps a separate post or link an article) the physics behind the C02 saturation theory ie Does more and more C02 add to more warming because it pushes the radiative force higher into the atmosphere OR is our atmosphere saturated with C02 and thus no more of the ~17 um re radiated IR energy can be trapped by the addition of MORE C02?

  12. Vincent says:

    I think Bjorn Lomborg’s comments are very sensible. I’ve often puzzled over the fact that societies seem so reluctant to spend money in order to protect themselves against predictable repetitions of past extreme weather events, such as floods, droughts and hurricanes, yet think it’s appropriate to spend huge sums of money combating a very uncertain effect of rising CO2 levels.

    Surely a better approach would be, for example, to determine the historical level of flooding in a particular area before building one’s house, then make sure that one’s house is raised above those past flood levels.

    If one has some concern that rising CO2 levels might cause increased severity of flooding in the future (and there’s no sound evidence so far that this is the case) then to be on the safe side, one should build one’s house perhaps a metre or so above the worst previous flood level.

    I suppose the explanation for why such procedures are often not a part of the building regulations, is that local governments do not want to stymie economic development in their area. Too many people might decide that the extra cost of raising a house 4 metres high on concrete piers is too much and might decide to live and work elsewhere.

    Hopefully the Trump administration will stop spending money on wasteful projects which will eliminate many from the free ride they have had shouting “Danger Will Robbins”

    If, as is his stated intent, he is able to cut the federal budget by $1,000,000,000. many things will change, not least the grants given to measure inanities.

    Certainly that should balance the budget and begin to pay off the debt.

    Will it hurt? Some people! Those who have been living off the borrowed money and those who have been living off transfer payments!

    But someone has to be hurt and if we don’t do it now, then when?

    So the waste of fighting some vague climate change agenda at the long term expense of the national, even international economy, will, hopefully go away.

    As an aside, I believe the best alternative for industry is nuclear. As it is a centralized source, solar and other less centralized sources should be used by small companies and individuals.

      Extremely well said, Dr. Spencer.

      As an independent operational meteorologist observing the global atmosphere daily the past 4 decades, this is what I’ve observed while the planet has warmed slightly and CO2 levels have increased.

      1. The best weather, climate, growing and living conditions for life on this planet in at least 1,000 years, since the Medieval Warm Period that has evidence from 100 legit studies.

      2. The planet is greening up, crop yields and world food production are smashing records. Some of this is from good weather, some from increasing CO2. Much from technology.

      3. Some measures of extreme weather have decreased(violent tornadoes). Decreasing the meridional temp gradient by warming the higher latitudes most means the atmosphere does not have to work as hard to redistribute the heat imbalance.

      4. Global drought has decreased slightly

      5. Arctic ice reached the 2nd lowest level this last September, since humans have been able to accurately observe it.

      6. Sea levels continue to increase at around an inch/decade.

      7. The slightly warmer atmosphere(and oceans) have increased precipitable water values slightly and caused a slight uptick in rains, including high end/extreme events.

      8. There has been no trend in hurricanes/typhoons. The ACE index maxed out in the mid 1990’s.

      Life on this planet has always done better when temps were a bit warmer than this. The 1 deg. C of warming has been beneficial. The 120ppm increase in CO2 has been massively beneficial.
      Based on authentic science and biology, most life should continue to benefit with increases even greater than that.

      If the busted climate models had been correct, one could see some potential problems evolving for human life that decided to live and build along the coasts…….even while much of the rest of life welcomed the warmth.

      Maybe now, we can live in the real atmospheric and biological world and not the one programmed into computers that simulate/speculate on a future world based on mathematical equations to represent a theory.

        The natural California drought continues to rapidly be “washed” away from natural climate/weather as reservoirs have also filled this month. In fact, only the southern parts of California still have long term drought, with more wonderful rain on the way…….several inches in the south the next few days.

        Starting early next week, there will be a pattern shift and the West Coast will dry out under a natural upper level ridge.

        Why use the term “natural”?

        Well, its been assumed that the term climate change, refers to “human caused” climate change and not natural climate change (-:

        For instance, when folks blamed the California drought on climate change, we all knew they meant “human caused”.
        Or the first widespread, severe US cornbelt drought in 24 years in 2012(despite that being a record without drought) being from or being worse because of climate change.

        Or climate change making Super Storm Sandy worse(Hurricane Hazel in 1954 was stronger and 1 of 3 hurricanes to hit the same region in 3 months of 1954).

        In today’s world, many folks automatically look for a connection between extreme weather events and (human caused) climate change. There is no evidence of this, outside of the slight increase in high end rain events and increase in record warm minimums.

    As much as I agree with your approach outlined in this article I would like to ask your opinion on the recent work showing that there is no “proof” that human emissions are effecting the atmospheric content or the global temperature. Hertzberg and Schreuder, 2016 concludes with Nothing in the data supports the supposition that atmospheric CO2 is a driver of weather or climate, or that human emissions control atmospheric CO2.
    This supports Salbys contentions. Wallace etal 2016 demonstrates no correlation of human emissions and global temps as well as no tropospheric hot spot that is an expected fingerprint of enhanced greenhouse warming. You also did at least one post on the possible alternative explanation for increasing atmospheric CO2. With all these in consideration do you really expect(but can’t prove) increased human caused warming?

    Here is a wonderful graphic display by Prof Hans Rosling showing the worlds countries health improvements over the last 200 years. If only we could get everyone to spend the 5 minutes to watch his video there would be very few people who would doubt the benefits of fossil fuels

    Amazing how all countries started as a tight bunch at the bottom left corner but once the IR started and developed quickly the wealthier western countries moved away. But now a lot of the once poorer countries have almost caught up to Europe, Nth America, OZ, Japan etc. Incredible to think that this has happened over the last 60+ years and certainly within my lifetime. The graphics and data collection for his display were all financed by the US taxpayer and today everyone can quickly look at all the UN and other data and easily understand it.

    Of course Lomborg and his mate Ridley have highlighted the incredible health benefits since the beginning of the IR and paid the price demonstrated by verbal abuse etc .

    I don’t buy Lomborg’s “$100 T” number for a second.

    First of all, everyone here should be a skeptic about numbers that are mentioned but not proved in any way — numbers whose methodology is not even presented.

    That’s true and all of you know it.

    If I said addressing climate change would save $100 T, every one of you would be jumping on me expecting to see my methodology and proof.

    Mindless accepting Lomborg’s number shows you are more interested in propaganda then science.

    Far more than this, well established and respected environmental economics have come to much different conclusions.

    William Nordhous of Yale, one of the most eminent climate economists in the world, who Republicans justs loved more than a decade ago for his promotions of cap-and-trade programs (programs conceived by Republicans as a market solution to pollution, which has worked for SO2 and NOXs), comes to much different conclusions.

    He published a 2013 book titled “The Climate Casino,” that everyone here should read.

    Like Lomborg, he uses models (mostly his DICE model) to estimate costs.

    On pg 174 he gives his results, showing that a 20% reduction in 2025 global emissions woudl cost about 0.25% of world personal income.

    If we take world personal income to be GWP (gross world production), about $70 T, that’s about $250 billion.

    Far, far lower than Lomborg’s result.

    Lomborg’s number is so outrageous that, frankly, it ought to set off the BS detector of everyone here. It simply doens’t smell right.

    Very well put once again Dr Spencer. What continues to annoy me about the whole climate change propaganda is that we are constantly being bombarded in the media with claims that crops are ripening earlier or later or whatever the case may be, because of climate change. The Great Barrier Reef is bleaching because of warmer water temperatures or lower water levels oh they seemed to have forgotten that the sea level is supposed to be rising because of global warming. The claims being made are just a tad premature. With the accepted temperatures having only warmed less that 1 degree F how can people try to justify the start of armagedon. I just wish everyone would take a deep breath and stop continually blaming everything on climate change. I look forward to your next post.

  25. David Appell says:

    By the way, there are other numbers out there that have far different conclusions than Lomberg. And that are published and peer reviewed.

    Im suspect youll all simply dismiss these numbers, and Roy too, for no reason other than you dont like them.

    Short answer: reductions of fossil fuel emission SAVE MONEY and SAVE LIVES.

    Benefits of ~$250 B/yr, 5-10 times larger than the cost of such reductions.

    From:

    Climate and health impacts of US emissions reductions consistent with 2C, Drew T. Shindell et al, Nature Climate Change, published online 22 FEBRUARY 2016 | DOI: 10.1038/NCLIMATE2935.
    http://www.nature.com/nclimate/journal/v6/n5/full/nclimate2935.html

    From the abstract: We examine the impacts of such highly ambitious scenarios for clean energy and vehicles. US transportation emissions reductions avoid ~0.03 C global warming in 2030 (0.15 C in 2100), whereas energy emissions reductions avoid ~0.050.07 C 2030 warming (~0.25 C in 2100). Nationally, however, clean energy policies produce climate disbenefits including warmer summers (although these would be eliminated by the remote effects of similar policies if they were undertaken elsewhere). The policies also greatly reduce damaging ambient particulate matter and ozone. By 2030, clean energy policies could prevent ~175,000 premature deaths, with ~22,000 (11,00096,000; 95% confidence) fewer annually thereafter, whereas clean transportation could prevent ~120,000 premature deaths and ~14,000 (9,00052,000) annually thereafter. Near-term national benefits are valued at ~US$250 billion (140 billion to 1,050 billion) per year, which is likely to exceed implementation costs. Including longer-term, worldwide climate impacts, benefits roughly quintuple, becoming ~510 times larger than estimated implementation costs. Achieving the benefits, however, would require both larger and broader emissions reductions than those in current legislation or regulations.

            The burning of fossil fuels is the cause of the huge increase in health and longevity cited in Rosling’s youtube piece cited earlier.

            The fact is early in the Industrial Revolution pollution was not seen as a concern. Additionally, controlling soot and particulates and other such are relatively expensive and are usually not the first things a young, ‘backward’ economy is concerned about.

            Later, as the society becomes richer, due to the large amounts of energy available and the evolution of the industrial economy from one of heavy industry to consumer goods, pollution control becomes more important. For all intents, it is a consumer good.

            At the same time, so much excess time becomes available, it allows people the ability to become advocates for all sorts of esoteric causes – saving the snail darter, spotted owls, creepy crawlers and other such. I wouldn’t be surprised for some radical environmentalist to take up saving salmonella.

    And here is the 2016 US EIA report, forecasting that co2 emissions will increase by 34% by 2040. See page 3. Just a pity that Obama and Holdren etc didn’t have enough brains to read their own report.

  36. barry says:

    Roy,

    You are betting that global warming will be mild and beneficial.

    If I understand your position, you do this by rejecting a large share of research on climate sensitivity for reasons that are based more on a political outlook (lack of trust in the researchers) than an analytical one.

    Last I read from you, you dismiss research on the ice age transitions of the late Quaternary, that suggest a stronger climate sensitivity than you have outlined. Your view is that the knowledge on these transitions is too uncertain, though you’ve not detailed why, AFAIK. It seems that, rather than incorporate that uncertainty into your own analysis of future climate change, you dismiss it outright such that it does not impinge on the likelihood of your own analysis.

    There is a wider spectrum of possible futures/climate sensitivity estimates in the literature, your view being limited to a narrow band. I think you could be a lot more even-handed.

    So could the Trump administration.

    Did they truly “delete” every mention of climate change from the government website?

    No.

    Content from the Obama administration was removed. The USA.gov website was cleaned out, same as 8 years ago. The Trump administration deleted nothing. They have been busy filling up the website with their own material.

    The misinformation here is pure political theatre. A trap for climate warriors (whatever their bent) who have trouble disentangling science from politics.

    • ren says:

      Is new ways of influencing the climate are beneficial for the environment? Can you assure us of this?

    • Norman says:

      barry

      You were commenting on Dr. Spencer’s view of Climate Sensitivity.

      Here is an older article you may find interesting.

      http://journals.ametsoc.org/doi/pdf/10.1175/1520-0450(1979)018%3C0822%3AQCTPIO%3E2.0.CO%3B2

      I think reality would suggest that for some unknown reason Climate scientists are inflating the climate sensitivity figure (at least double I think).

      The accepted value for doubling of Carbon Dioxide alone is 3.7 W/m^2

      This article found that the Plank Feedback is around 1 k/(3.3 W/m^2)
      http://www.atmos.albany.edu/facstaff/brose/classes/ATM623_Spring2015/Notes/Lectures/Lecture03%20–%20Climate%20sensitivity%20and%20feedback.html

      They use this low number (1 K/(3.3 W/m^2) to get a value for how much the globe would warm with an increase of 3.7 W/m^2.

      I really do not see the logic on how they come up with such a number.

      With the Earth system you have some downwelling radiant energy used up in evaporation so it takes even more input energy to reach some equilibrium higher value.

      Look at things this way. With no water and a blackbody surface you would need to continuously add 390.079 W/m^2 to maintain a surface temperature of 288 K. If you wanted to raise the surface temperature of your blackbody by 1 K you would have to add an additional 395.525 W/m^2.

      To increase a blackbody without evaporation losses by 1 K would require and additional 5.446 W/m^2. I cannot see anyway they could arrive at a figure of 3.3 W/m^2 raising the Earth’s surface temperature by 1 K when to raise a blackbody would require a minimum of 5.4 W/m^2. On Earth some of the Watts go to evaporation so you actually need even more than 5.4 W/m^2 to raise the surface by 1 K.

      If you use the 5.4 figure you can see the Climate scientists have increased the sensitivity 1.6 times higher than what is possible under ideal conditions. There seems no way a 3.7 W/m^2 radiant energy increase would warm the Earth’s surface by 1.2 C. Under ideal conditions (no evaporation or thermals) the increase could only be 0.69 C. I think Roy is much closer to real science than the abstract and complex programs of a climate model.

      • David Appell says:

        Norman wrote: “I think Roy is much closer to real science than the abstract and complex programs of a climate model.”

        You do know, I hope, that Roy uses a complex model to convert satellite readings into atmospheric temperatures?

        • Norman says:

          David Appell

          Thanks for your thoughts but the context of my post was not to discredit climate models because of their complexity. It was a question of when you get a model that claims a 3.7 W/m^2 increase in radiant energy will raise the surface temperature by 1 K you should seriously question the model’s output. Explained above that to raise a blackbody object in space from 288 K to 289 K would require and addition of 5.4 W/m^2 to the objects surface to accomplish such a temperature rise. How would it be possible that a 3.3 or 3.2 W/m^2 increase in energy could somehow raise the Earth’s surface temperature to 1 K and a 3.7 W/m^2 increase would raise it to 1.2 K (or C)?

        • David Appell says:

          Norman, you misunderstood.

          UAH and RSS use complicated models to extract average tempertures from microwave readings.

          These aren’t “climate models.” But they certainly are models. Complicated models. Carl Mears of RSS think the surface results are more reliable.

        “I cannot see anyway they could arrive at a figure of 3.3 W/m^2 raising the Earths surface temperature by 1 K when to raise a blackbody would require a minimum of 5.4 W/m^2.”

        An important point is that radiative forcing is defined with respect to the tropospause, not the surface.

    I’ve got a theory about the excessive concern about climate change, which I’d like to hear comments on.

    I’ve had experience in relationships with women who appear to have OCD (Obsessive Compulsive Disorder).

    Such women are terribly concerned about cleanliness and very minor issues which they perceive as a huge, potential problem. They tend to clean the house every day, check several times that the doors are locked, be excessively concerned about ‘use-by’ dates on food labels, and if they have children, they protect them from every imaginable situation that might be contaminated with dirt or bacteria.

    Their children, as a result of such extreme maternal protection, often develop problems in later life because their immune system was not exercised in combating basic infections when they were young.

    I can’t help wondering if the typical climate-change alarmist falls into this category of some type of OCD.

    Climate change alarmists seem to ignore the capacity of organisms to adjust to changing conditions. They seems to want everything to remain the same, like a house which is perpetually clean because the house-proud woman vacuums and dusts it every day.

    What do you think? This is just an hypothesis at this stage. (wink)

        In my previous comment, or hypothesis relating to OCD, I’m searching for an explanation for the fixation of certain scientists on problems arising from CO2 levels.

        I would categorize this fixation as a form of OCD, for reasons that I’ve mentioned. If you want to debunk my hypothesis, then please provide some evidence that might imply that what I suggest is not true, or cannot be substantiated.

        • Lewis says:

          Vincent,

          It is difficult, if not impossible, to answer your question. There are more general answers available, however.

          Some people have guilt feelings about themselves, their situation, even about how humans affect other animals and plants. There are also those who believe humans have more influence on their environment than could possibly be true. We see the results of this in human sacrifices to the gods in order to alleviate/atone for some perceived misbehavior of the people towards the gods which caused the gods to unleash drought or floods or volcanoes.

          Today, with the climate change alarmists, the process is the same. Alleviating their individual or group guilt requires punishing someone – usually not themselves. It becomes a matter of belief, not much different than religious belief, and the result – see the Inquisition – is the same. So they rationalize their meanness to others in order to assuage their personal guilt.

          I hope that helps.

    Asia could have been the world leaders and perhaps USA and Europe would have lagged way behind. Who knows. But we do know that the world changed quickly over the last 200+ years and life expectancy has doubled in the developed world. And the developing world is now catching up quickly and all because of the use of fossil fuels.

    Plus we now live in a much safer and greener world since the die was cast more than two centuries ago. At least you prove that you understand your predicament. The US has had the biggest reduction in co2 emissions over the last decade because of the change from coal to gas. Germany on the other hand has wasted endless billions on stupid unreliable energy like S&W and yet haven’t reduced co2 emissions. The poor German people have copped it in the neck because of some of the highest electricity prices on the planet. And of course no measurable change to temp by 2100 at all.

    Since you seem to be able to locate material on polar conditions I am wondering if you have a history of the extent of the very cold polar air. Currently the super cold air is located in Eastern Russia and Alaska. My question is the size of the super cold air (subzero by many degrees) getting smaller or time so it covers less surface area or is about the same size and just sits over different locations on any given year? Sometimes Europe, sometimes US.

    Alaska had been warmer the last few years and now it is in the frigid grip of the very cold blob of air.

    Thanks.

    Above you talked about climate sensitivity. I had a response for you and I would like to include another. A lot of the “Official” climate sites think clouds might be a positive feedback but the CERES data clearly shows this is very flawed thinking.

    Under a warmer world you get more evaporation (which should act like cooling that I have seen no one include in their discussions of climate sensitivity) which should produce more clouds.

    https://ceres-tool.larc.nasa.gov/ord-tool/jsp/EBAFSFCSelection.jsp

    If you Visualize the Data and bring up the tool’s graphs (not mine) you will see the last graphs show the amount on energy reaching the surface Clear Sky vs All Sky is a positive 25 W/m^2 at the peak. The overall effect of clouds is to considerably allow less radiant energy to reach the surface. If you discuss a few W/m^2 increase in radiant energy to the surface, the increase in any clouds would greatly overwhelm the increase.

    The more I look at the details of this climate sensitivity the more it looks like political manipulation by the Obama Administration (via grants to hungry scientists like leading a horse with a carrot stick). The European Union and Obama wanted to create a large super government to take care of everyone. Climate Change is the one idea they could come up with that could rally all the diverse groups of citizens under one common banner “Save the Earth!” The movement seems much more political and control minded than a scientific research. Hopefully now real science can come shining through the haze of politics and the suppressed voices can rise up and speak the Truth!

    • Gordon Robertson says:

      Norman…speaking as someone who has had a lot of experience with positive feedback in electronics I find the definitions of PF on the Net and elsewhere to be seriously off base.

      In electronics, there are two kinds of PF. One is used in servo systems and it is nothing more than a positive error voltage that indicates a monitored device has deviated from a set reference voltage that would indicate it’s desired function. With that kind of PF there is no gain or amplification involved.

      The other kind of PF is the kind implied by climatologists who incorrectly insist there is an amplification in the atmosphere due to PF.

      In physics, that kind of PF is clearly defined and the definition does not state that PF amplifies anything. PF is part of a system of amplification but it requires an amplifier.

      Before saying more, anyone can throw around the term positive feedback. That was NOT a shot at you, I am talking about the general use of the term. In certain climate science minds it implies an exponential, runaway effect in which temperatures increase out of bound due to PF.

      Mathematically, gain with positive feedback is: G = A/(1-AB)

      Where G = overall system gain or amplification
      A = the gain in the amplifying device, often a transistor
      B = feedback

      You can see immediately that the feedback component is just one part of the system and that it has to be less than one. B cannot be equal to 1 or greater than one since a value of 1 gives a denominator = 0 and greater than one would give a negative gain.

      The term 1 – AB is the crux of the system. The feedback is always a fraction and multiplied by the amplifier gain. If the feedback is negative, it changes the sign to 1 + AB and the gain is reduced. If B is +ve, 1 – AB is always less than 1 and AB < 1.

      A typical small signal transistor gain is 100. You can see that the PF must be a small fraction to keep AB 0 ; G -> infinity. Therefore, as
      AB -> 1 ; (1 – AB) -> 0.

      That’s the basis of Hansen’s argument for an atmospheric tipping point. Hansen never bothered to explain where the amplifier is found in the atmosphere. He presumed many things that have no basis in the physics definition of true positive feedback.

      Water vapour feedback makes no sense. The feedback component is not water vapur it is infrared energy transmitted by the water vapour. It is the IR that must be considered as part of the feedback system which comprises a theoretical cyclical exchange of IR between the surface and GHGs in the atmosphere.

      Immediately, it becomes plain that such a cyclical system has no amplifier and that it has losses. Furthermore, the IR flux involved in the cycle is a tiny fraction of the overall massive IR flux from the surface.

      • Gordon Robertson says:

        The system completely messed up my math. It printed:

        A typical small signal transistor gain is 100. You can see that the PF must be a small fraction to keep AB 0 ; G -> infinity. Therefore, as
        AB -> 1 ; (1 AB) -> 0.

        That should have read:

        You can see that the PF must be a small fraction to keep
        AB < 1.

        Anyway as 1 – AB goes to zero, the gain (G) goes to infinity.

        As AB goes to 1, 1 – AB goes to 0.

    • David Appell says:

      Where is the peer reviewed publication proving this?

      Come on, Norman, you’ll gain instant fame by showing the clouds are a negative feedback.

      • Norman says:

        David Appell

        I think CERES data already strongly proves the point. I can prove nothing. I command no satellites nor compile data from such. Others are doing this and providing their results. Their results show clearly that clouds overall greatly reduce energy to the surface of the Earth.

        Do you have evidence proving contrary? I already steered you to a peer reviewed article on clouds that made the claim that a loss of clouds increased energy to the surface by 6.8 W/m^2 over a couple decades. You rejected the paper so it seems when it comes to peer reviewed material it can only be useful when it agrees with your belief systems.

        Because of this doesn’t it seem pointless for me to provide you with peer reviewed material? You will reject what you don’t like.

        Did you even take a look at CERES? Is the data they provide worthless to you? They have graphs over 16 year time frame showing Clear-Sky conditions vs All sky. All sky means with clouds included and when you compare the two conditions you can clearly and without doubt see that, based upon their evidence, that a lot more energy reaches the surface in clear sky conditions meaning clouds have an overall cooling effect (some clouds warm other cool, the total effect is cooling on a global scale and it is a considerable amount).

        Can you answer why you have a complete fear of CERES graphs? You never look at them or consider them. What is causing this fear in you? Is it because you know they do not support your views?

        Then don’t look at the graphs. Not my problem. The CERES graphs clearly show clouds allow less overall radiant energy to reach the surface. I can’t make you look and am clearly NOT asking you to be a research assistant. I was hoping you would look and with your intelligence would explain how these graphs do not show what I am stating they do (though it would seem unlikely you could do this).

        I really do not know why you would at least look at the graphs and see what I am claiming. It really does not take much time. Maybe 5 minutes. Then at least you would know what the claim is. As it stands now you are just be obtuse. You won’t look but you will post claims the information or my interpretation are not valid and you base it upon other links I have put into posts.

        Since you won’t look at the graphs, please do me a favor and if I post them to someone else to look at, don’t add your comments, they are highly unwelcome. If you give the courtesy to at least look, consider and then reject based upon a logical evaluation I can respect that. What you are currently doing is pointless and shows a deep dishonesty in your nature. You don’t look at the data but claim it is wrong or incorrect. That is really a stupid poster and that is not an insult but a correct assessment of a person who ridicules something they will not even attempt to look at and then give stupid explanations of why they won’t.

      It’s not just this issue, the ignorance spans the breadth of science. There is an ad running on TV by Gilead, a drug manufacturer, urging baby boomers to get tested for hepatitis C. There is no such virus according to the tests for a virus put forward by the Louis Pasteur Institute.

      The pantomime Hep-C virus is reported to remain hidden in the human system for decades then suddenly appear. The same claim was made for HIV, which has not been identified either according to the Louis Pasteur criterion.

      Here is a good article that explains this phenomenon about so-called viruses that remain hidden.

      http://www.whale.to/vaccine/slow_viruses.html

      This is the kind of pseudo-science with which we must endure. One of the authors, Peter Duesberg, is an authority on viruses and won the California Scientist of the Year award at one time. He has been in scientific purgatory since he claimed HIV is a harmless passenger virus that could not possibly cause AIDS.

      Very recently, the scientist who discovered HIV, Luc Montagnier, seems to have validated Duesberg. He claimed HIV will not harm a healthy immune system. Montagnier claimed further that he has never isolated HIV, purified it, or even seen it. His team hypothesized it based on RNA strand found in contaminated blood. The same applies to HEP-C.

      The amount of money the drug companies can make from this pseudo-science is staggering. The potent drugs provided by them come with a disclaimer that the drugs cannot cure HIV and may cause AIDS infections and liver damage.

      Montagnier explained that AIDS is caused by oxidative stress which can result from malnutrition, contaminated water, parasites, drug abuse, or questionable sexual practices. He claimed HIV can only operate once the immune system is compromised.

    I have long suspected that climate alarmists have psychological issues that compel them to use any convenient cause to further there religious ideologies. I got the evidence watching the huge crowds of idiots attending the inauguration.

    Actress Ashley Judd completely lost any semblance of logic or reasoning when her rant compared Trump to Hitler. I wished for a moment that she had been making such a statement against Hitler when he was in power to see the difference. Had she done that at a rally against Hitler, she and all the participant would have immediately been incarcerated in a concentration camp where most of them would have died a slow, cruel death.

    She came across as an utter idiot. Same with Madonna who I have always considered an idiot. She suggested blowing up the White House.

    Let’s get it straight, Madonna has made a career of sexual perversion intermingled with a questionable singing talent. He notion of propriety was kissing Britney Spears on the mouth when they both appeared on stage. She is from England, yet there she was at a religious rally claiming she’d like to blow up the White House. Had she been of Middle East appearance she would be in jail right now.

    And there was Jane Fonda, another idiot who recently flew over a Tar Sands site then lectured the residents of the Tar Sands town Fort McMurray, Canada, to move elsewhere and find a different kind of work.

    I wonder if anyone caught the TV coverage of the woman who was removed from a flight because she literally attacked another passenger because he seemed to support Trump? One of her beefs was that Trump…she raised two fingers of each hand to suggest quotation marks…was opposed to “climate change”. A complete raving idiot who had to be removed from the plane.

    It’s unfortunate but there are people who have obsessive/compulsive issues coupled with a god-complex wherein they feel responsible for saving the planet from who knows what.

  56. Ross Brisbane says:

    When it comes to climate change and energy policies, the new administration is focused on rolling back the Obama administration’s programs to cut greenhouse gas emissions and opening up more oil and gas resources to drilling.

    To justify this approach, the website claims that eliminating Obama’s Climate Action Plan, which includes regulations on emissions from power plants, as well as clean water regulations will increase American wages “by more than $30 billion over the next seven years.”

    Sounds great, right?

    Trouble is, it’s a made-up claim. The nonprofit research and journalism group Climate Central debunked this on Friday.

    Turns out that this $30 billion figure comes from a non-peer reviewed paper written by a finance professor at Louisiana State University in 2015, and it was written for a fossil fuel industry organization. The paper didn’t analyze the specific power plant regulations the Trump administration wants to repeal, which makes the administration’s claim dubious from the start.

    Instead, the paper’s author wrote about the potential economic impacts that the U.S. might expect if it began drilling for more fossil fuels from public lands. Its conclusions are hardly robust enough to base national policy decisions on, given that they don’t factor in the costs that will come from climate damages. The paper reportedly doesn’t correctly analyze the combined effects of removing regulations, either, which also includes costs.

    The White House site also makes no mention of how academics and the previous administration have said that the environmental regulations Trump seeks to dismantle would themselves boost part of the economy.

    For example, in justifying its regulations in the first place, the Environmental Protection Agency (EPA) calculated that the overall economic benefits of power plant carbon emissions reductions would be in the tens of billions of dollars a year.

      Ross Brisbane…the US EPA is a hotbed of climate alarmists. I am looking forward to it being brought back into scientific reality.

      You can nitpick all you want about minor issues, the major issue is that the EPA will no longer be spreading climate propaganda.

      The Trump admin is also proposing cutting funding to the IPCC and the UN in general unless the UN gets off it’s partisan and fantasy games.

      I am a left-winger and I am not looking forward to cuts they have in mind for social programs, even if they don’t affect me. However, breaking this trend to political-correctness is well worth it. Trump is not saying anything much different than what many of us, including left-wingers, have been thinking for some time.

      Our freedom of speech has gradually been encroached upon to the point where we can no longer talk about reality without being branded as racist or homophobic.

      I don’t agree with their position on abortion but when a woman on TV news claimed they were expecting several million abortions in the coming year I had to wonder what we have come to.

      A woman’s decision on abortion should be her own but when it comes to 2 million unwanted babies I have to wonder what they heck is going on.

      I am not a racist either but here in Canada we had multiculturalism forced on us without the least amount of consultation as to what we wanted as Canadians. We need to take our country back and tell the elitists and politically-correct where to get off.

      People come to Canada because of the civility and lifestyle it presents yet many get here and carry on with the same lifestyle that forced them to leave their own countries. Rather than enforce Canadian law and our way of life, politicians like our Prime Minister are apologizing for who we are.

      That’s why Trump is president in the US and why the UK left the European Union.

            Because, if corporations can find a loophole, they are happy polluters, regardless of their impact on anyone downstream.

These energetic particles must be dissociated from those associated with chromospheric eruptions because they are differentiated by their composition, their charge and their spatial dispersion, the latter being much more localized.

        Today the theory of Dr. Jack Gosling is accepted because it is demonstrated that the coronal ejections are at the origin of the strongest magnetic storms and the phenomena of auroras that accompany them. These phenomena are related to the high intensity and configuration of magnetic field lines, their speed, and not to the energy of the particles.”

      The IPCC is seriously confused. In 2001 they claimed future climate states cannot be predicted then they used the term ‘projected’ to infer a prediction without actually predicting anything.

      Unvalidated models cannot predict.

      In 2013, they revealed a warming hiatus of 15 years from 1998 – 2012. That hiatus is now 18 years long. In the same breath they raised the likelihood that humans are causing the warming from 90 to 95%.

      Warming??? What warming??? They just said there had been no warming.

  67. Daniel Kirk-Davidoff says:

    Roy,

    You cannot possibly guarantee that $100 trillion spent to avoid global warming will result in a lower standard of living for the world’s poor. We have plenty of wealth and wealth-generation capacity for everyone in the world to have a decent standard of living now- we’re just not making the decision to turn our productive capacity to that end. I have no idea where you’re getting the $100 trillion figure from, but let’s just assume you mean a sum over the next fifty years, so assuming (almost certainly wrongly) that it would be front loaded in real terms, that’s $2 trillion per year. North American GDP is $19.5 trillion. We could loose $2 trillion of our GDP and have no impact at all on poor people- after all, the top 20% of US population alone earned $3.6 trillion. These households all had incomes above $100,000. They could all take a 50% loss in income, and not be anything like poor.

    So even if it really takes 3% of global GDP to convert to a low-carbon economy, the only reason that has to come out of the income of poor people is if that’s the way we want it to be. I don’t want that, and I don’t see why it should be that way. The alternative, obviously, is that rich people would just have a harder time finding cheap domestic labor, because more people had the option of working on installing solar panels, wind turbines and nuclear power plants.

    As far as agricultural productivity goes, you know very well that only a very small component of the large increase over this century has anything to do with CO2 fertilization. It has mostly to do with deliberate nitrogen fertilization, and some to do with improved breeding (mostly to take full advantage of the nitrogen).

    Roy, if what you care about is helping poor people, how about you spend more time doing that and advocating for it here. How specifically would you like us to change public policy to help poor people? I’ve got an idea- let’s tax investment income the same as regular income, and raise the top income bracket to 40%. That way, it will make more sense for firms to spend the money they have available for salaries and stock options on people lower down the income scale, rather than on wealthier people, who would just see the government take a big chunk of it.

    Best regards,
    Dan

    • WizGeek says:

      @Dan: Poverty is a symptom whose underlying cause is insufficient education, insufficient trade skills, inappropriate career choices, and, in rare cases, unforeseen circumstances. Why treat the symptom that is poverty when it’s far more effective to address the underlying causes? Like some of the unethical members of the medical profession, treating symptoms instead of causes increases repeat business and, therefor, revenue. Poverty has its ne’er-do-wells–they’re called pandering politicians and public sector leeches.

      • David Appell says:

        And government spending does a lot to provide sufficient education, sufficient trade skills, create business choices and provide a safety net for unforeseen circumstances.

        • WizGeek says:

          @David: Recognizing that “government spending” is a convenient euphemism for “redistribution of taxpayer money”, the overarching question is why should ideological government bureaucracies be the entities that determine social winners and losers? Education serves the community, and the community is comprised of individuals engaged in mutual commerce; so commerce should heavily influence (and support) basic education that best serves the community via skills/career education and selection. Yes–I know, I know–we all should be free to choose our life’s trade and career (blah, blah, blah,) but if said freedom of choice is likely to result in undesirable or unusable skills, then where’s the corresponding acceptance of personal responsibility for having made such a incongruous decision? Where is the protection of a community’s liability for these poor personal decisions? Additionally, the “safety net” for employment gaps is in reality an existing, mandatory insurance policy funded by a payroll tax–much like Social Security–because some ideologies hold the condescending opinion that the general population is too ignorant to take care of itself or too ignorant to learn how to do so.

      • Gordon Robertson says:

        WizGeek…”Why treat the symptom that is poverty…”

        Symptom??? Have you ever been poor???

        The poor have to eat, they have to pay rent, they need medical care. Some can’t even get clean drinking water and die from the lack thereof. Those are not symptoms they are facts…absolute reality that ideologues don’t seem to understand.

        Some in Canada can’t afford the power to heat their abodes. It will only get worse if climate alarmists have their way.

        I am a left-winger who grew up in poverty. I know first hand what it means. I differ from other left-wingers in that I cannot stand political correctness nor can I stand the practice of subverting science as a means to enable an unrelated agenda. Climate propaganda is not helping the poor it is working against them.

        Unlike what many thing, poor people are not pathetic dependents. In fact, the poor I grew up with were proud and independent. They were people with a deep integrity who did not rely on handouts. Poverty is about far more than circumstances. There are places where no amount of energy or integrity will get you ahead.

        One woman in Ontario complained to the prime minister that her power bill now exceeds her mortgage. This is wrong and it has to change. People cannot be held hostage by governments who use power sales as a means of income.

        • WizGeek says:

          @Gordon: Yes, I’ve been poor (single mother with limited skills) and at one time lived out of my vehicle or by the grace of co-worker’s couch; but this is a misdirection–I did what was necessary to remove my symptoms of poverty by retooling, apprenticeship, and a lot of hard work–I addressed the causes. Like medical professionals not needing to be a victim of a disease, one need not be poor to understand the symptoms of poverty and its underlying causes.

          Children aren’t born to be poor–this is self evident. Children might be raised in poverty, but that’s not a decree they’re doomed to be poor adults–plenty of examples of poverty-to-fame people. Children might be culturally indoctrinated to accept poverty, but that’s a social failing not rectified simply by unqualified money injection because that just treats the symptom, not the cause. And thus we’ve come full circle.

          We can have endless dialog using generalities and euphemisms centered on the well-meaning but ineffective enabling of faceless, disconnected and dehumanizing policies. The real work to address poverty needs to be very personal and honest discussions between people in need and professionals in social science, psychology, career development, and money management as well as building stronger ties to family, community, and spiritual circles. But this is a discussion for another time in another thread. 🙂

          • Nate says:

            Growing up in a poor community predicts very well whether you are going to be poor. Why do people with kids want so badly to move away from poor communities?

          • WizGeek says:

            @Nate: Did you miss this section in my post?: “Children might be culturally indoctrinated to accept poverty…” Cultural poverty is a very real problem that is best rectified by deprogramming parents, influential, positive-thinking community leaders, and crime prevention.

    • Gordon Robertson says:

      Dan…”How specifically would you like us to change public policy to help poor people?”

      If public policy had anything to do with it poverty would have been eradicated long ago. The truth is that the intent is lacking. That brings it back to human greed and ignorance.

      Roy is correct The money going to fight the pantomime climate change should go straight into programs for the poor. There is no point whatsoever in attempting that indirectly by carbon taxes as proposed by the UN to redirect funds from wealthy nations to poor countries.

      If you are going to help the poor, DO IT!! Stop talking about it, DO IT!!

      We can send a space craft to Mars but we can’t solve poverty. Pathetic!!

      I would gladly pay a carbon tax if I knew that money went directly to helping the poor. Here in Canada where I live the carbon taxes go to private companies.

      • David Appell says:

        “Because the tax must, by law in BC, be revenue-neutral, the province has cut income and corporate taxes to offset the revenue it gets from taxing carbon. BC now has the lowest personal income tax rate in Canada and one of the lowest corporate rates in North America, too.”

        • Gordon Robertson says:

          da…”Because the tax must, by law in BC, be revenue-neutral, the province has cut income and corporate taxes to offset the revenue it gets from taxing carbon”.

          Proof positive of your abject naivete. I happen to live in a province with one of the most corrupt governments imaginable. We have the highest rate of child poverty in Canada.

          https://thetyee.ca/News/2011/12/05/CarbonTrustDrawsHeat/

          Our former premier was caught driving under the influence in Hawaii and did not resign. He left us with a debt of 2 billion dollars.

          The party is known as the BC Liberal Party. It used to be the Social Credit Party who were right of Attila the Hun. When they were decimated at the polls circa 1990 for abject corruption, the leader just mentioned was left in a vacuum. Rather than rebuild the party he loaded a leadership convention of the Liberal Party, which had just been revived, and stole the party from the guy who revived it.

          Anything you read about the carbon tax from their supporters, like The Economist, is propaganda. The current premier promised to help families but she omitted the small print, she meant wealthy families. As I said, we have the highest level of child poverty in Canada.

          The carbon tax goes straight into the pockets of private companies. This government has no idea what revenue neutral means, there sole objective is to feather the pockets of their private supporters.

          They took a public corporation, BC Hydro, and gave chunks of it away to private concerns. They allowed former party hacks to build small power generating stations that supplies power to the Hydro electrical grid at considerable profit.

    hi,
    watched hundreds of hours on climate change.
    2 questions
    does the current modelling take into account the refrigeration
    affect of evaporation when water changes phases.

    the other is. do any of them take into account the affect the sun spot activity, the affect of procesion of the earth in its orbit ,the malvitish cycle and lastly the affect of the yearly movement of magnetic north as well as the moon slow movement away from the earth.

    normal farmer asking a question
    we have to produce the food this is critical.
    we as humans still know so little and the interaction of diff factors are so complicated we just do not have the computing power or long term accurate data to make accurate presumptions
    that i why we all still act on faith and hope.

    • David Appell says:

      max:

      Yes to your first question.

      No to your second question. The climate is not very sensitive to sunspots or solar changes, and the orbital factors change far too slowly to affect decadal or even century-scale climate.

    Hi Roy I tried your email which bounced back. Found this interesting tool on the NASA web site. They have temp data from 1890 to 2010. They also show you how to produce graphs using excel with gradients ie rate of temp change. I used said tools to calculate the rate of temp change from 1916 – 1945 and also from 1977- 2004 and guess what the rate of change of temp is identical (ok a 0.14% difference). This is screaming out to me that the causes of the temp rise are one and the same (with a periodicity of about 60 years. Now the CAGW proponents are claiming that mans influence via CO2 impacted post 1950’s. So they cannot account for this identical rise prior to 1950. Please construct your own graphs. I can supply my spread sheet if required.

  76. The problem here is that the only really authoritative studies of the costs of global warming, the IPCC reports and the Stern report, both unambiguously indicate that the costs of not acting are going to vastly exceed the costs of acting.

      Why do you dismiss Nordhaus’s studies?

    • Gordon Robertson says:

      Elliott…”the IPCC reports and the Stern report, both unambiguously indicate that the costs of not acting are going to vastly exceed the costs of acting”.

      The IPCC also reported an insignificant warming (could have been a cooling according to error bars) in the 15 years between 1998 and 2012. That has been extended to 18 years by UAH.

      Can’t have it both ways. If the real data shows no warming and the projectors claim we need to do something, something is seriously wrong.

    I don’t think anyone seriously believes that one or two extra molecules CO2 in 10,000 of air, is ever going to drive any noticeable change in the climate. Most proponents are not particularly interested in the science so it’s pointless to debate it, it’s about the ‘solutions’ it’s a 100% political movement
