Climate Q&A

What does NASA have to do with global warming?

NASA employs the world’s largest concentration of climate scientists. NASA’s mission to study Earth involves monitoring atmospheric conditions, global temperatures, land cover and vegetation, ice extent, ocean productivity, and a number of other planetary vital signs with a fleet of space-based sensors. This information is critical in understanding how Earth’s climate works and how it is responding to change.

In addition to collecting information about the Earth, NASA also builds global and regional climate models to understand the causes and effects of climate change, including global warming. NASA shares its climate data and information with the public and policy leaders freely and in a timely manner. As part of the U.S. Climate Change Science Program, NASA works with other agencies—including the National Oceanic and Atmospheric Administration, the U.S. Geological Survey, the Environmental Protection Agency, the Department of Energy, and many others—to conduct research and to ensure climate science results are available to all users to address a broad range of societal needs.
