No conclusion, still improving
Updated climate models are clouded by scientific biases, researchers findhttps://phys.org/news/2022-09-climate-clouded-scientific-biases.htmlCloud and radiation biases over the Southern Ocean have been a long-lasting problem in the past generations of global climate models," said corresponding author Yuan Wang, now an associate professor in the Department of Earth, Atmospheric, and Planetary Sciences at Purdue University. "After the latest CMIP6 models were released, we were anxious to see how they performed and whether the old problems were still there."

Wang said the researchers were also motivated by other studies in the field that point to the Southern Ocean's cloud coverage as a contributing factor to some CMIP6 models' high sensitivity, when the simulations predict a surface temperature that rises too quickly for the rate of increased radiation. In other words, if improperly simulated, the Southern Ocean clouds may cast a shadow of doubt on the projection of future climate change.
