Recent assessments have found the last glacial maximum implies a climate sensitivity of 2.4C (1.4C to 5.0C): https://t.co/3b43E7sSw4
And the Pliocene implies a sensitivity of 3.1C (2.3C to 4.7C): https://t.co/V3LGLOWxcY
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: https://t.co/Qe0Vv4ekLM

@25_cycle Agreed, and it is important to distinguish between the two concepts (ESS and ECS) when analyzing paleo evidence for modern climate change. Cheers!

How much will the Earth warm from greenhouse-gas emissions? 📈
@_ClimateCraze Hi @_ClimateCraze -- if you take a closer look at the paper, I think you'll find it is not hyperventilating. In fact we are downweighting the most extreme warming scenarios based on multiple lines of evidence

Our new paper on tropical cloud feedbacks is out in @NatureGeosci. We show that changes in high cloud area do not provide a negative feedback on climate change like previously thought. Instead, high clouds become thinner with warming, which acts as a...
