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 […]

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 […]

International Ocean Satellite Monitors How El Niño Is Shaping Up

Sentinel-6 Michael Freilich is the latest satellite contributing to a 30-year sea level record that researchers are using to compare this year’s El Niño with those of the past. Not all El Niño events are created equal. Their impacts vary widely, and satellites like the U.S.-European Sentinel-6 Michael Freilich help anticipate those impacts on a […]
