NASA explores. From its earliest days of sounding rockets and balloon-borne instruments, to Apollo and Hubble and missions to Mars. This mission of exploration has also always focused on our own corner of the universe, Earth - the home frontier. Earth is still the only planet we've ever been to, as this video explains.

NASA scientists are working to understand if our land and ocean can continue to absorb carbon dioxide at the current rate – and for how long.

This visualization shows sea surface temperature (SST) data from January 2016 through March 2020.

This animation shows the change in atmospheric nitrogen dioxide (NO₂) levels as a result of COVID-19 stay-at-home restrictions.

Carbon dioxide is the main heat-trapping greenhouse gas that humans emit. How much do you know about it and its impact on global warming and climate change?

A visualization shows global temperature changes per latitude zone from 1880 to 2022.

Color-coded map of changing global surface temperature anomalies from 1880 through 2022. 

This movie shows the evolution of several regions of the Greenland Ice Sheet between 2008 and 2300 based on three different climate scenarios.

Ice covers 10 percent of Earth's surface and helps moderate the planet's temperature. Glaciers and ice sheets around the world are melting at an alarming rate. By keeping an eye on Earth's ice from space, NASA satellites help us understand the global effects of climate change.

Nuestra Tierra tiene fiebre. Nuestros científicos creen que la temperatura de la Tierra podría subir de 3 a 10 grados Fahrenheit durante este siglo.

Continuing key Earth observations is really important to see how our atmosphere, land, and ocean are changing over time. A long-term record, combined with cutting-edge observations from the new NASA Earth System Observatory, will continue to push boundaries to better understand our ever-changing planet.

The relentless rise of carbon dioxide levels in the atmosphere.
