Global Climate Change
Vital Signs of the Planet
CO2 video for carbon feature
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.

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.

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.
