Check out the @pnas.org highlight for our new paper on how Paleoclimate Pattern Effects in the Pliocene lead to tighter constraints on the modern response to CO2 (a.k.a. climate sensitivity)
Proceedings of the National Academy of Sciences@pnas.org · 6mo agoThe Pliocene climate was more sensitive than the current climate, suggesting that the upper bound of potential 21st-century warming—an estimate informed by Pliocene warming—should be revised down from 5 °C to 4 °C, according to the authors. In PNAS: https://ow.ly/U5H750Y5yUo
Really excited to see this paper out!! Led by @vtcoop.bsky.social we show that if you use cold and warm paleoclimates together, you can reduce uncertainty in Earth's climate sensitivity by quantifying the pattern effect and more precisely constrain future climate change www.pnas.org/doi/10.1073/...

Got a call to visit the work post room as there was a parcel for me… (first time in 10+years!) It was a book, sent to contributing authors I presume, of papers that came out of an ISSI workshop in 2022. It’s easy to forget that journals often still have physical copies… a joy to flick through.

Fantastic to have spent two days at Leeds discussing physical climate science with new and old colleagues. Looking forward to the opportunities ahead @earthandenvleeds.bsky.social. And it’s great to be back where it all began 20 odd years ago as a student, but now on the other side of the fence…
