Hello fellow Wikipedians,

I have just modified one external link on Community Earth System Model. Please take a moment to review my edit. If you have any questions, or need the bot to ignore the links, or the page altogether, please visit this simple FaQ for additional information. I made the following changes:

• Added archive https://web.archive.org/web/20150411061405/http://www2.cesm.ucar.edu/models to https://www2.cesm.ucar.edu/models

When you have finished reviewing my changes, you may follow the instructions on the template below to fix any issues with the URLs.

"High climate sensitivity in CMIP6 model not supported by paleoclimate"

Please add information about this to the article.

Here is what I added to 2020 in science, it could also be used here (you can also edit it there):

• Scientists report that one of the climate models – the CMIP6 model CESM2 – is not supported by paleoclimate records. Comparing simulations of this model with geological evidence suggests that it's climate sensitivity is too high. This indicates that this model may not perform realistically at high CO2 concentrations, overestimating global warming at high levels of CO2 where its equilibrium climate sensitivity is 5.3 °C and modelled tropical land temperature exceeds 55°C. They recommend using paleoclimate constraints of past warm and cold climates to benchmark the performance of climate models.

Please also add information on this (from the press release):

The predecessor to CESM2, the CESM1.2 model, did a remarkably good job of simulating temperatures during the Early Eocene, according to the researchers. It has an equilibrium climate sensitivity of 4.2 C
