Recent assessments have found the last glacial maximum implies a climate sensitivity of 2.4C (1.4C to 5.0C): www.science.org/doi/...
And the Pliocene implies a sensitivity of 3.1C (2.3C to 4.7C): www.pnas.org/doi/10....
Paleoclimate evidence generally provides the strongest constraint on high ECS.

ECS is certainly state-dependent (as the paleoclimate literature notes!). But we can learn something about what to expect in the future based on prior warm periods in the Earth's history, as well as more recent observations and climate models. agupubs.onlinelibrary.wiley.com/doi/10.1029/...
An Assessment of Earth's Climate Sensitivity Using Multiple Lines of Evidence

It underplays Hansen's work, saying it only relies on paleoclimate (ice age) info. That's not true. Hansen (& @leonsimons.com) also use recent temp readings during IMO2020 changes, and also used decrease in Earth's measured albedo in past 25 years.

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

#FossilFriday Fossils of Belemnites (Belemnitella americana) like the ones pictured are important to Geochemistry.
The famous "Pee Dee Belemnite" are historically a standard for Carbonate isotope ratios of δ13C.
δ13C is a stable carbon isotope used in many ways, such as inferring paleoclimate

Alt: GIF from the movie Starship Troopers. A group of soldiers are standing in a row wearing helmets and armor. One of the soldier says "I'm doing my part", subtitles show the text. This was from a scene in the movie that was a military recruiting ad.

that had previously favored them. It’s written as a general-audience synthesis rather than a paleoclimate methods paper, which is why isotope datasets and circulation models aren’t foregrounded, though the underlying literature is cited throughout with links. 🧵✂️

Higher RCPs and SSPs likely provide the most accurate indications of climate change over the next decades.
We need scenarios more in line with policy based greenhouse gas and aerosol emissions and models with paleoclimate and NASA satellite corrected climate sensitivity:

The ten I have picked and summarise in this article take a journey through the whole subject, starting with the paleoclimate as far back as 485 million years ago. We then jump forward to just 8.7 million years ago, the last time the Arctic was permafrost free but CO2 levels were only 350ppm.
