@leafwax and colleagues estimate a climate sensitivity of 3.4C based on reconstructions of temperature and CO2 from the past.
Glad to see this major paper out! I've been citing the EarthArXiv version ever since @leafwax's great presentation at #VAMQUA20. A huge contribution by paleoclimatology to the climate-sensitivity conversation.

@rgatess @curryja Just saw this as well. Adding another piece of supporting evidence that ECS is near 3C: https://t.co/y26c6ncBv2
Paleodata: The last glacial maximum was 6 degrees cooler than the Holocene and yields an estimate of climate sensitivity of 3.4C for a doubling of CO2 in the atmosphere.
Then @leafwax from .@uarizona and colleagues provide a fantastic reconstruction of the climate of the last glacial maximum. High-level conclusion: cooling of about 6 C relative to modern (with many additional insights). https://t.co/acf49C5b47
Important new work with further paleoclimate constraints on climate sensitivity from the last ice age, which line up well with the WCRP estimate from earlier this summer.
And there is that ECS value of near 3 C again! The evidence continues to indicate that an ECS of <= 2 C is nothing more than wishful thinking. The good news is that it is unlikely that the ECS is > 5 C.

Our paper on Last Glacial Maximum (LGM) cooling and climate sensitivity is out today in @nature! This represents four years of work, so it feels really good to see it released. Here's a short thread on what it means... https://t.co/mH80pU5lZM
