Romero et al present an ice-free and paleo sea level chronology for James Ross Island in the northeastern Antarctic Peninsula area. They found that the advance of the local ice cap happened sometime after 40,000 years ago, and this implies a period of retreated ice in MIS 3. #Geology #Antarctica #IceSheets #SeaLevel https://doi.org/10.1016/j.quascirev.2026.110133

A robot swarm is on a mission to map #Greenland’s perilous #icesheets The fleet of drones, subs and sensors will map ice melt to forecast #climate #tippingpoints Data from expedition funded by #UK’s secretive new inventions agency, will feed into climate models. Idea is to forecast when #ice melt will tip climate-regulating ocean currents into shutdown, and try to develop early warning system that would let humanity know when #glaciers are changing https://www.sciencenews.org/article/robot-mission-map-greenland-ice-climate https://archive.ph/OaxnC

How is this for a feedback loop? Ice sheets build up during a glaciation lowering global sea level → reduced water load leads to increased mid ocean ridge volcanism after a 10-20 kyr lag → volcanism releases iron in the ocean → iron causes plankton blooms → atmospheric CO₂ goes down → ice sheets build up #ClimateChange #IceSheets #SeaLevel https://www.nature.com/articles/s41561-026-01982-7
