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)
The 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
