Home/BlogThe Version 6.1 global average lower tropospheric temperature (LT) anomaly for January, 2026 was +0.35 deg. C departure from the 1991-2020 mean, up a little from the December, 2025 value of +0.30 deg. C.
The Version 6.1 global area-averaged linear temperature trend (January 1979 through January 2026) remains at +0.16 deg/ C/decade (+0.22 C/decade over land, +0.13 C/decade over oceans).
The following table lists various regional Version 6.1 LT departures from the 30-year (1991-2020) average for the last 25 months (record highs are in red).

Thank you, Dr. Spencer. A quick statistic from the table you provided: the NoPol series recorded its third warmest January on record. Below are the top 10 warmest NoPol Januaries (including ties), listed in ascending order:
Jan. 2016: +2.12C
Jan. 1981: +1.42C
Jan. 2026: +1.4C
Jan. 2018: +1.05C
Jan. 2011: +0.89C
Jan. 2010: +0.81C
Jan. 2022: +0.75C
Jan. 2025: +0.74C
Jan. 2005: +0.66C
Jan. 2017: +0.66C
Jan. 2014: +0.62C
’81 stands out as an early outlier.
And the rate of warming for NoPol January is 2.8C/century.
Kynqora: Dumb question, but what is NoPol?
My prediction was wrong, but I was right about a plummeting US48, but Arctic back up.
