Antarctic Sea Ice Near Historic Lows; Arctic Ice Continues Decline

Sea ice at both the top and bottom of the planet continued its decline in 2024. In the waters around Antarctica, ice coverage shrank to near-historic lows for the third year in a row. The recurring loss hints at a long-term shift in conditions in the Southern Ocean, likely resulting from global climate change, according […]

Studying Arctic Ice

In this image from July 12, 2011, crew from the U.S. Coast Guard Cutter Healy retrieve a supply canister dropped by parachute during the Impacts of Climate on Ecosystems and Chemistry of the Arctic Pacific Environment, or ICESCAPE, mission. ICESCAPE was a multi-year project sponsored by NASA to determine the impact of climate change upon […]

Meet NASA’s Twin Spacecraft Headed to the Ends of the Earth

Launching in spring 2024, the two small satellites of the agency’s PREFIRE mission will fill in missing data from Earth’s polar regions. Two new miniature NASA satellites will start crisscrossing Earth’s atmosphere in a few months, detecting heat lost to space.

NASA Study: More Greenland Ice Lost Than Previously Estimated

A new, comprehensive analysis of satellite data finds that majority of glaciers on the landmass have retreated significantly. The Greenland Ice Sheet has shed about one-fifth more ice mass in the past four decades than previously estimated, researchers at NASA’s Jet Propulsion Laboratory in Southern California reported in a new paper.

This US-Indian Satellite Will Monitor Earth’s Changing Frozen Regions

NISAR will study changes to ice sheets, glaciers, and sea ice in fine detail, as climate change warms the air and ocean. NISAR, the soon-to-launch radar satellite from NASA and the Indian Space Research Organisation (ISRO), will measure some key Earth vital signs, from the health of wetlands to ground deformation by volcanoes to the […]
