Understanding Climate Change

Global warming and its impacts

NCAR researchers are leaders in the field of climate science. Scores of our scientists have played key roles in assessing the state of the science for the Intergovernmental Panel on Climate Change. The NCAR-based Community Earth System Model has been an important analysis tool for the IPCC reports, and this sophisticated software is freely available for use by climate researchers across the world.

As experts on climate, we get asked a lot of questions about global warming and climate change. Here are some resources to help answer those questions, and a look at some of our most recent research findings.
