NASA is an expert in climate and Earth science. While its role is not to set climate policy or prescribe particular responses or solutions to climate change, its purview does include providing the robust scientific data needed to understand climate change and evaluating the impact of efforts to combat it. NASA then makes this information available to the global community – the public, policy- and decision-makers and scientific and planning agencies around the world. (For more information, see NASA's role.)

The following selected resources from U.S. government organizations provide information about options for responding to climate change.
