Climate Change - From the unique vantage point in space, NASA collects critical long-term observations of our changing planet - EARTH

NASA applies ingenuity and expertise gained from decades of planetary and deep-space exploration to the study of our home planet. The Earth Science Division operates more than 20 satellites in orbit, sponsors hundreds of research programs and studies, and funds opportunities to put data to use for societal needs. We develop new ways to observe the oceans, land cover, ice, atmosphere, and life, and we measure how changes in one drive changes in others over the short and long term. While listening to and collaborating with industry leaders, international partners, academic institutions, and other users of our data, we deepen knowledge of our planet, drive innovations, and deliver science to help inform decisions that benefit the nation and the world.

How Do We Know Climate Change is Real?

There is unequivocal evidence that Earth is warming at an unprecedented rate. Human activity is the principal cause.

Earth-orbiting satellites and new technologies have helped scientists see the big picture, collecting many different types of information about our planet and its climate all over the world. These data, collected over many years, reveal the signs and patterns of a changing climate.

Wildfires and Climate Change

Earth's warming climate is amplifying wildland fire activity, particularly in northern and temperate forests. When fires ignite the landscape, NASA’s satellites and instruments can detect and track them. This information helps communities and land managers around the world prepare for and respond to fires, and also provides a rich data source to help scientists better understand this growing risk.
