BREAKING from @science.org: The Trump admin is seeking to kill nearly all climate research at NOAA, its climate science agency.

Its near-final budget proposal would end all NOAA research labs, academic institutes, and regional climate centers. And it wants to fully end the NOAA Research division.

AMOC news can be confusing—is it slowing? Collapsing? Remaining stable? There’s studies that claim each!

That’s why, instead of the latest headline, I always rely on what @rahmstorf.bsky.social has to say—he’s studied it for nearly 40 yrs and knows how each new study fits into the bigger picture.

The AMOC is slowing, it’s stable, it’s slowing, no, yes, …

There's been a bit of media whiplash on the issue of AMOC slowing lately - ranging from the AMOC being on the brink of collapse to it being more stable than previously thought. AMOC, of course, refers...

This is a misunderstanding of the 1.5C target, which was never based on a special significance of 1.5C with respect to tipping points, but rather a recognition that we were already experiencing dangerous and escalating climate change, and 2.0C allowed too much further escalation.

Leon Simons @leonsimons.bsky.social · Nov 29

🚨 New alarming study🚨

'the 1.5 °C warming target [..] was set largely based on avoiding dangerous climate change" [..], its utility may deserve reconsideration'

'trends in the tail-widening of extreme heat distribution over the past 65 years [..] in some cases exceed the model spread entirely'
