Recent assessments have found the last glacial maximum implies a climate sensitivity of 2.4C (1.4C to 5.0C): science.org/doi/10.1126/scia… And the Pliocene implies a sensitivity of 3.1C (2.3C to 4.7C): pnas.org/doi/10.1073/pnas.25… Paleoclimate evidence generally provides the strongest constraint on high ECS.

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: ow.ly/clo450Y5yUn

Modern-day ECS estimates from recent assessments, including the Sherwood, Webb et al (2020 study (yellow), IPCC AR6 (red) and this study (blue). Dots show central estimates. The coloured bars show the likely range and the very likely range is given by whiskers. Chart by Carbon Brief based on data provided by V Cooper and K Armour

Theres an important new study from many of the leading researchers on paleoclimate and climate sensitivity. They provide a new, more robust estimate of climate sensitivity from the last glacial maximum, suggesting a sensitivity of 2.9C (95%: 2.1 to 4.1C) science.org/doi/10.1126/scia…

I'm excited to share a new paper in @ScienceAdvances led by UW's @VTCoop showing that the last ice age provides much stronger constraints on Earth's climate sensitivity and future warming when ice-sheet driven temperature patterns are accounted for. science.org/doi/10.1126/scia…

Last Glacial Maximum pattern effects reduce climate sensitivity estimates

Ice sheet–driven temperature patterns amplified glacial cooling, implying less future warming than previously estimated.

New paper of ours on tropical high clouds is out now! The satellite-observed area feedback, aka “iris” feedback, is not as stabilizing as previously thought. If all else is equal, this would increase climate sensitivity slightly. @NCAR_CGD @NCAR_Science doi.org/10.1029/2023JD039364

UW's @VTCoop has shown that accounting for spatial patterns of temperature change makes the LGM an even stronger constraint, which with other lines of evidence suggests climate sensitivity is very likely between about 2K and 4K. Look for this work soon! eartharxiv.org/repository/vi…

New paper in @PNASNews led with @cristiproist shows that a weird spatial pattern of temperature change has slowed global-mean warming since 1980. Because the pattern could evolve in the future, observed warming doesn’t help us constrain long-term warming. pnas.org/doi/10.1073/pnas.23…
