The climate is changing. We want to know what happens next.

We are experts in how the climate system works. For decades, we've diligently studied the complex connections that determine whether a region is prone to monsoons or droughts, summertime thunderstorms or giant winter blizzards, vicious heatwaves or intense cold snaps. 

With this understanding, we've built sophisticated climate models that allow us to both understand past and present climate as well as investigate how the climate is likely to change in the future.

Global warming is already having a noticeable effect on the United States and the world. Warming air and oceans have begun amplifying storms, altering precipitation patterns, and contributing to sea level rise. Our scientists are working to quantify the changes that are already upon us and predict what the future may bring, as well as creating tools that allow other scientists to do the same.
