One of my New Year's resolutions is to make data more accessible.
Also to protect it from data purges by e.g. anthropogenic climate change-denying regimes..
Find the data uploaded to GitHub here:

En er is best nieuws te melden: #LeonSimons liet zien dat metingen laten zien dat de opwarming veel sneller gaat dan de modellen voorspellen en @gerrithiemstra.bsky.social ging in op de toenemende weersextremen die daarmee gepaard gaan.

The Northern Hemisphere mid-latitude Sea Surface Temperature increase is the same magnitude of a trilopical El Niño peak and most likely permanent, as that's where most of the shipping desulphurization and therefore the net/aerosol radiative forcing increase happened.

There has been quite some buzz around the new emission scenarios proposed to be used for future climate modeling work.

We will speak with Detlef van Vuuren lead author of the new paper about this on Climate Chat, live soon:

'Global warming acceleration in satellite observed lower-tropospheric temperature' (Preprint)

"Projections based on the accelerated trend estimates suggest the potential for an additional 0.5–1.0°C of warming within the next decade [...] roughly three to five times the 1981–2024 linear trend."
