Celebrating NASA and the planet

Arctic and Antarctic regions act as air conditioners for the Earth system.

The connection between sea-level rise and Antarctica

Greenhouse gases are vital to life on Earth, but the growing concentration of certain gases, such as carbon dioxide, is throwing the planet’s delicate balance out of whack.

NASA keeps track of sea level change and its causes.

Illustrating the complicated patterns of rising and falling ocean levels across the globe from 1993 to 2015.

Climate models used by the Intergovernmental Panel on Climate Change estimate global temperature and precipitation patterns will change throughout the 21st century given current rising greenhouse gas concentrations. This visualization is based on a scenario in which carbon dioxide concentrations reach 670 parts per million by 2100, up from around 400 ppm today.

NASA's OMG and Operation IceBridge missions are investigating the thinning of Greenland's ice sheets from both above and below.

NASA-supported researchers have found that ice covering Greenland is melting faster than previously thought. The action is happening out of sight, below the surface.

Earth’s surface temperatures in 2017 were the second only to temperatures recorded in 2016, an El Niño year, and the hottest ever, since global estimates began.

The sea ice cap changes minimum summertime extent, which typically occurs in September, has been decreasing for decades at a rapid pace.
