Join our session: “ *Bridging Proxy Records and Climate Models: Toward Robust Paleoclimate Insights Across Timescales* ” We invite contributions tackling the mismatch between proxy records and climate model simulations—one of the key challenges in paleoclimate science.

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.
