The changes point toward increasingly unstable ecosystems at high latitudes

Insulating effect of deeper snow is thawing ancient carbon permafrost reserves

UCI, NASA scientists studied the role of warming sea water on the island’s land ice

New tool enables year-round, direct measurements of frozen arctic soils

UCI and NASA JPL scientists study impact of warm, salty water beneath glaciers

Antarctica and Greenland are dotted with automated weather stations, 30-foot metal tubes equipped with sensors to record temperature, atmospheric pressure, wind speed and other conditions. The outposts gather a lot of useful readings for scientists hoping to understand the transformation of polar environments brought on by climate change, but data formats vary from station to […]

Sea ice is melting due to global warming, enabling greater maritime access to the Arctic Ocean. Emissions from transoceanic cargo ships taking advantage of this could either warm the climate further by darkening snow and ice surfaces or cool it by enhancing cloud reflectance. In a study published recently in the American Geophysical Union journal […]

Findings paint less dire climate picture, as ancient emissions are more harmful

UCI is sustaining its outsized reputation for tracking and tackling environmental challenges
