"Equilibrium climate sensitivity — how sensitive the Earth's climate is to changes in atmospheric carbon dioxide — may be underestimated in individual climate models, according to a team of climate scientists," writes A'ndrea Elyse Messer for Penn State News.

"The researchers [which included Andrei P. Sokolov of EAPS] used the Massachusetts Institute of Technology Earth System Model to test the sensitivity of probability distributions for three climate system properties, including equilibrium climate sensitivity. They included results from 25 different state of the science Earth system models, where each one is configured differently."
