Earth’s ice can be divided into two categories: ice on land — like glaciers and ice sheets — and sea ice, which forms from frozen sea water. Sea ice plays an important role in regulating our planet’s temperature. Catch up with 5 fast facts about sea ice: https://go.nasa.gov/3ja2s6j pic.twitter.com/Wcm67VX4rY

The research underscores how Arctic sea ice influences a region that plays an integral role in regulating the pace of global warming, sea level rise, and other effects of human-caused climate change.pic.twitter.com/bJuvfSJKQq
The findings come from the North Water Polynya, a large patch of exposed ocean in the Arctic that opens 4-5 times in winter. Allowing heat and moisture to escape from the ocean, this sea ice “hole” can be large enough to cover entire U.S. states such as Virginia.pic.twitter.com/BLfh4vkihv
Arctic sea ice hit its annual minimum extent on September 16. Our scientists Linette Boisvert and Alek Petty explain what that means:https://theconversation.com/arctic-sea-ice-hits-its-minimum-extent-for-the-year-2-nasa-scientists-explain-whats-driving-the-overall-decline-166549 …
3 years ago today, the
@NASA #ICESat-2 satellite launched from the Vandenberg Air Force Base. In 3 years, ICESat-2 has fired nearly 1 trillion laser shots to measure the heights of Earth’s icy regions, #trees, forests, & landforms, worldwide. Learn more at https://icesat-2.gsfc.nasa.gov/ pic.twitter.com/na2scjGy5p
#CRYO2ICE campaign, @NASA’s ICESat-2 and @ESA_EO’s CryoSat-2 look at Earth’s changing cryosphere together. The missions synced their orbits to conduct new science that would be impossible to explore with each mission independently.

ICESat-2 fires its laser 24/7! The satellite works night and day, filtering out those pesky light photons from the Sun. Here, ICESat-2 measured tree heights, the forest floor, the underwater depth of a lagoon, and even ocean waves off the southern coast of Mexico.pic.twitter.com/DNZCnBUnQ9
ICESat-2 data shows that in recent years, the Greenland ice sheet lost an average of 200 gigatons of ice per year, and the Antarctic ice sheet lost an average of 118 gigatons of ice per year, raising sea levels. Here’s how much ice was lost:https://twitter.com/NASAEarth/status/1258054469285228545?s=20 …
