This equation relates Sun Temperature to Earth Temperature:

TE = TS (((1-a)^0.5 * Rs)/(2*D)))^0.5)
Where TE is blackbody temp of the Earth in K
TS is the surface temp of the SUN in K
Rs is radius of the Sun (6.96 X 10^8 meters)
D is distance between the Sun and Earth in meters (1.5 X 10^11)
a is albedo of the Earth

The equation you posted on your website is not correct.
TE = TS ((((1-a)/e)^0.5 * Rs)/(2*D)))^0.5)

This equation has e = emissivity of the Earth included again.
(1-a) is equal to e and it already includes the emissivity of the Earth as well as the Clouds.

Division by e is obviously wrong since if e = 0 (a perfect reflecting Earth), it will produce an INFINITE Earth temperature (TE)!

Someone has changed the correct equation on Wikipedia to this hilarious and obviously wrong form.

Focusing produces magnification.

The Magnifying Properties of a Magnifying Mirror

“Because of the focusing of the light caused by the parabolic shape of magnifying mirrors, the light is concentrated more and more as it approaches the focal point. This concentration of the beams of light results in a magnification of the image reflected by the mirror. As the beams of light get closer and closer to the focal point, they become more and more magnified, which accounts for the increase in magnification as you step away from the mirror.”

and invite you to comment on it. Thanks

You said…
“The insulation, which is cold, causes the temperature to rise (i.e. “heat up”) because it reduces the rate of heat loss from a body that is generating heat. The Earth absorbs
energy from the Sun (call it a furnace), and if that energy cannot escape, or escapes less fast, then the Earth will rise in temperature (i.e. “heat up”).”

Wrong!

An increase in the temperature of the Earth past what the Sun (the only energy source source) provides energy for, requires CREATION of Energy.

This is simple Conservation of Energy that even Grade School Kids understand.

Just like a blanket cannot CREATE energy and CANNOT HEAT UP a human body.

PROOF:
Radiation emitted by a human body

“The total surface area of an adult is about 2 m^2, and the mid- and far-infrared emissivity of skin and most clothing is near unity, as it is for most nonmetallic surfaces.Skin
temperature is about 33 deg C, but clothing reduces the surface temperature to about 28 deg C when the ambient temperature is 20 deg C. Hence, the net radiative heat loss is about Pnet = 100 W.”
http:
//en.wikipedia.org/wiki/Black_body

Did you get that? The human body’s surface temperature DROPPED from +33 deg C to +28 deg C!

I will repeat it AGAIN, The human body’s surface temperature DROPPED from +33 deg C to +28 deg C!

Blankets can’t increase a human body’s surface temperature of +33 deg C because the body has to supply heat energy to the colder blanket to increase it’s temperature.

The result is a DROP in the human body’s surface temperature down from +33 deg C to +28 deg C!

It is IMPOSSIBLE for the blanket to increase the Body surface temperature of +33 deg C since that would require CREATION OF ENERGY.

That’s why it is IMPOSSIBLE for the colder atmosphere to heat a -18 deg C Earth up to +15 deg C as the fantasy “Greenhouse Effect” claims.

The colder atmosphere CAN ONLY COOL THE EARTH just like a blanket CAN ONLY COOL THE HUMAN BODY.
———————–
If ANY, I repeat ANY, heat energy from your +33 deg C body were reflected back by a mirror and absorbed by your body, your body would increase in energy and it’s temperature would rise above +33 deg C.

This already VIOLATES the Law of Conservation of Energy since ENERGY HAS BEEN CREATED and a perpetual motion machine has been created.

But it does not stop there, it is just the beginning of an upward spiral of energy Creation and temperature increases.

Your now warmer body that exceeds +33 deg C will radiate more energy to the mirror and that would be reflected back to your Body further increasing it’s energy and temperature.

This is a perpetual motion machine in a positive feedback loop.

The cycles of energy increase and temperature increase would continue until your Body burst into flames!

(See 2nd Law of Thermodynamics, Perpetual Motion and The Law of Conservation of Energy)

I suggest that you immediately patent your Radiator/Tin Foil Perpetual Motion Machine, you will be RICH and FAMOUS.
——————
The Earth not only absorbs UV from the hotter SUN, it absorbs heat energy from the ENTIRE EM spectrum produced by the hotter SUN.

And, the Earth will radiate the same amount watts/m^2 it absorbs from the Sun in the IR spectrum.

The Earth’s radiated heat energy can only flow to COLDER objects just like the 2nd Law states and The Law of Conservation of Energy requires.
——————
If heat energy could flow from cold to hot objects, every colder object around you would transfer heat energy to your body and increase your body temperature.

You would simply increase in temperature until you burst into flames.

That’s why Dry Ice, a Glacier or any other colder object does not cause your body temperature to increase.

So, all YOU are left with, AGAIN, is:

What a HOOT!

- Insulation is not an energy source, so it cannot heat ANYTHING up. That’s why Coffee in a Thermos Bottle will always cool and not HEAT UP.

Right from the very beginning of this entire thread you have completely misunderstood the whole point! My house is a heat source, as is the surface of the Earth. I have a furnace pumping out heat. The insulation, which is cold, causes the temperature to rise (i.e. “heat up”) because it reduces the rate of heat loss from a body that is generating heat. The Earth absorbs energy from the Sun (call it a furnace), and if that energy cannot escape, or escapes less fast, then the Earth will rise in temperature (i.e. “heat up”).

- Reflective foil does NOT make your radiator HOTTER

Oh yes it does. I have measured it. I have an electric storage heater in a conservatory. Putting foil behind it increases the surface temperature by about 2c.

it just concentrates more radiation in one direction

Yes, back towards the radiator… while reducing it in another direction. (See Antenna radiation pattern nulls and peaks)
Yes, out of the wall into the cold night air. And what do you think happens to the energy reflected back by the foil towards the radiator?

- 100% reflection does increase energy.
No of course it doesn’t! I never said it did. It simply reflects energy back from whence it came.

- If any energy could flow from cold to hot, you would burst into flames when you look in a mirror. (See 2nd Law of Thermodynamics and Perpetual Motion)

More rubbish. The 2nd law of thermodynamics only requires that in net terms that energy flow from hot to cold.

I do not burst into flames when I look in a mirror because the net gain in temperature is absolutely tiny because I am such a poor heat source.

Shine an arc lamp into a mirror from 10cm and see if it bursts into flames.

- Cold objects can absorb heat from Warm Objects, not the other way, that’s why you don’t burst into flames if you stand on a glacier. (See 2nd Law of Thermodynamics and Perpetual Motion)

You are just plain wrong. A glacier is giving out IR because it has a temperature above absolute zero. I am warmer standing on a glacier than I would be standing on dry ice.

The rate of flow of heat from hot to cold increases when the difference in temperature is greater. Dry ice is colder than water ice, hence I am warmer standing on a Glacier than dry ice.

Now that is common sense.

- I see you deny Weins Displacement Law in addition to The 2nd Law, The Law of Conservation of Energy, Heat Transfer Physics, Electromagnetic Physics, Vector Mathematics, Cause & Effect
I deny none of them. You just misunderstand them.

You still have not answered my question:
“Do you deny that the earth absorbs UV while simultaneously emitting IR?”
If you admit that it does, that blows a massive hole in you whole argument.

Such as putting cold reflective foil behind my radiators which make the radiators hotter.

Would a cold body that reflected 100% of the energy from a hot body back to that hot body warm it up?

If so, why is radiation reflected by a colder body any different from radiation emitted by a colder body?

We have discussed this endlessly before in this thread but all that is needed to comply with the 2nd law of thermodynamics is that the net movement of energy is from warmer to colder. It is still possible for a hot body to be both absorbing and emitting energy at the same time. After all, do you deny that the earth absorbs UV while simultaneously emitting IR?

If so, why can it not absorb IR while also emitting IR? They are after all just the same form of energy but at different wavelengths.

As for this:

I posted Proof that the AGW QUACKS have Deliberately and Fraudulently Lowered the Sun’s temperature to 5778K!

Now it is my turn to say “what a hoot!”.
