Global Average Temperature 2025

[Typhoon Tip]

...Continuation from 'Global Average Temperature 2024'  ( probably should have started this a couple of months ago - )

January 2025   ~ +1.8C above the pre 1850 level,  according to Copernicus

February 2025  ~ +1.8C above the pre 1850 level, according to Copernicus

March 2025 continued the remarkable trend, being the 2nd warmest March in the history of record,   https://phys.org/news/2025-04-global-temperatures-historic-highs-eu.html

we broken through the +1.5C threshold but it won't be recognized until we get a full year of this, so wait until the end of 2025 I guess to confirm it.

March tied for warmest on record using the Berkeley Earth dataset continuing the streak of record warmth which began in 2023.

CERES data updated through February. Noisy from month to month. Last month's anomaly came in lower after an upward spike in January. The 12-month average is starting to turn up so the net radiation bottom for this enso cycle has probably been passed. If so net radiation fell to a similar level following the 2015/16 and 2023/24 ninos. The 3-year average remains stubbornly high, indicating that the next big step won't be cooler.

Thank you for the update. One correction, however, just to be clear... Copernicus uses an 1850-1900 baseline. I know they refer to it as "pre-industrial" which may imply before 1850, but it is, in fact, based on the second half of the 19th century averages [even if a fair amount of industrialization had occurred by that time]. 

Not trying to be critical, just wanted to clarify. A lot of times, the choice of baseline can make a big difference. Of course, in that era, the changes were relatively smaller. Still, a baseline of 1800-1850 could be 0.1 or 0.2C cooler. Just not enough data from that era to say for sure.

frankly, I begin to think the PI distinction may be less meaningful since ~ 1998 anyway; since, the curve's become less linear and more exponential.   That changes the things, because something is happening endemic to these last 2 or 3 decades.   It's really like we need to change the narrative to "since pre super NINO 1998" 

The pre Industrial aspect is like a built in reminder that the 'momentum' in anthropomorphic forcing began when civility converted to an industrial format, but it appears some sort of trigger for feed-back induced synergistic heating is more recent, and dangerous once you get into non-linear responses.   We know PI began this - though the laity doesn't.  You know, in some quantum sense of it, probably really began when the first lesser hominid picked up a burning stick and light dawned some 300,000 years ago.   The curve was likely not linear all along, but to a close approximation, predictions based upon would be relatively well behaved. 

Case in point, the 2023: a whole planetary systemic temperature surged.   If a 1930s sci-fi writer conceived that in 2023 a temperature burst at a planetary scale would take place, it would probably be integral in a d-day plot.  When is the next unseen thing going to happen, and wtf is going to be when an entire planet farts.  Now that it has really happened...  guess were juts in it and not knowing if we're going to win it.
