🌊 🧊 📉 Global Sea Ice Area Maximum never peaked lower than it did this year...
Less sea ice leads to less sunlight reflection back to space, more (high latitude) heat uptake and even faster ice melt.
Lowest global sea ice maximum area on record. 🧪

I already found this quite striking:
Ignoring the tropics because of El Niño/La Niña, the past 12 months show record Sea Surface Temperatures for both hemispheres.
And the acceleration of warming over the Northern Hemisphere is painfully obvious:
We talked about this in detail on Climate Chat recently: www.youtube.com/live/BNZ_biC...

The scientific understanding is that we should see a decrease in Absorbed Solar Radiation from a negative PDO and a decreasing Net Flux Anomaly as the North Pacific rapidly warms.
The opposite is happening and that's a Big F*cking Deal (BFD) to use @drjamesehansen.bsky.social his phrasing. 1/

From the 2017 Hansen ea paper:
The Framework Convention (UN, 1992) and Paris Agreement (2015) define goals relative to "prein-dustrial" temperature, but do not define that period. We use 1880-1920, the earliest time with near-global coverage of instrumental data'

Hansen didn't 'switch the base period'.
And as explained in this thread, there's ample reason to use 1880-1920:
Thanks.
Is it fair to say that your 1850-1900 baseline is about 0.08-0.09 warmer than the 1880-1920, which is often used by Hansen et al.?
