In ca 2012, as part of the Discover the Physical Sciences Breakfast Lecture Series at the University of California, climate researcher Eric Rignot (NASA/JPL) outlined our understanding of changes in the major cryosphere hotspots in Antarctica and Greenland, in his talk titled “Response of the Great Ice Sheets to Climate Warming”. Read about his newest…

East Antarctica, which holds the potential of raising global sea level by almost 200 feet, has long been considered stable and unlikely to change in the future. But recent observations have hinted that East Antarctica is starting to wake. #TottenGlacier In this briefing, researchers will present new findings on how a group of glaciers in…

How burning Forests melt Ice Sheets

2018, Aerosols, Cryosphere, Deglaciation, Extreme Weather, Greenland, Heat wave, Ice Sheets, Impacts, Science Talk, USA, WildfireLeave a comment

Forest fires can melt glaciers thousands of miles away by changing the colour of the ice – all thanks to a heavy little particle called black carbon. This strange story of smoke, dust and algae looks at the lesser-known half of a positive feedback loop: not only does climate change make fires bigger and badder,…

This week, #NASAExplorers head back in time…by going underground. In the Arctic, a frozen layer of soil – permafrost – trapped dead plants and animals for thousands of years. As the climate warms, that soil is beginning to thaw, releasing carbon dioxide and methane. Release via https://www.youtube.com/watch?v=y7ZbghndiwQ
