Antarctica is losing ice quickly, in part because of climate change. Massive calving events, such as the one that formed the Delaware-sized (5,800 square kilometers, or 2,239 square miles) A-68 iceberg in 2017, can destabilize ice shelves and capture the public’s attention. But the infrequency of extreme calving events makes it difficult for scientists to […]
Vanishing Antarctic sea ice could lead to more storms in the Southern Ocean, new research shows. Scientists found that reduced Antarctic sea ice coverage in 2023 caused the ocean to lose extra heat to the atmosphere. That heat loss could disrupt ocean circulation currents and cause more frequent storms in areas where sea ice coverage […]

Credit: Sandee Oster Waterfall Bluff Rock Shelter (WB) (Eastern Cape Province (ECP), South Africa) contains archaeological deposits demonstrating persistent and continuous human occupation spanning from Late Marine Isotope Stage 3 (~39ka–29ka) to the mid-Holocene (~8ka). It is at this site that the first leopard seal (Hydrurga leptonyx) […]

A diagram shows one way the curtains could prevent warm seawater from reaching the terminus of the glacier. Credit: Nature (2024). DOI: 10.1038/d41586-024-00119-3 New studies about the Thwaites Glacier, also called the “Doomsday Glacier,” have sparked a conversation about geoengineering as a climate change solution. One study published in May and led by University of […]
