Late-night plotting in R for me is like speaking French after a few too many glasses. I can do it but it's not going to be great. 😅
(since ERA5 does not go back that far, I used the difference between 1850-1900 and 1940-1969 from DCENT as an offset, i.e., ~0.25°C)

Like in 2024, every single day this past year was warmer than the average of even the most recent reference period (1991-2020).

President Trump's attempt to dismantle it for political vengeance is beyond reckless.
We will fight against this dangerous scheme every step of the way.

We are organizing a session at EGU 2026 in Vienna, with a focus on climate sensitivity, radiative feedbacks and the pattern effect!
If you work on anything related to climate sensitivity, we'd love to have you! 🥳🥳🥳 Submit soon! :)

2025 will likely go down as the 2nd-longest ice-free period for the Western Hudson Bay polar bear population, continuing the long-term trend (now >1 month longer than in the 1980s).
