Simulation of past climate shows recent models may be too sensitive to carbon dioxide
A climate model simulation of the Early Eocene period roughly 50 million years ago returned temperatures that were too high compared to evidence in the geologic record, suggesting that the model may also project unrealistically high temperatures for the future.

Arctic Ocean likely to become ice-free in the summer for first time before 2050
The Arctic Ocean is likely to have its first ice-free summer before 2050, according to an analysis of simulations from more than 40 different climate models. How frequently the sea ice vanishes in the summer depends on the rate of greenhouse gas emissions in the future.

Irrigation alleviates hot extremes driven by human-caused climate change
New research finds that irrigation can cancel out, or even reverse, the increased risk of heat extremes associated with human-caused climate change.

NCAR climate model dataset available on the cloud
A massive dataset that is widely used by the climate and atmospheric research community to study phenomena such as extreme rainfall, ice loss, and extended droughts in North America, is now freely available on the commercial cloud.
