AGU Fall Meeting 2013: Our understanding of future Arctic change is informed by the history of past changes, which often have been both large and abrupt. The well-known ice-age events such as the Younger Dryas show how sea-ice changes can amplify forcing to produce very large responses, with wintertime sea ice especially important. These changes…
Published on YouTube Dec 5, 2013: The most sobering evidence of the planet’s response to greenhouse gases comes from the fossil record. New evidence scientists are collecting suggests that ice sheets may be more vulnerable than previously believed, which has huge implications for sea level rise.
Glacial isostatic adjustment, why we have glacial and interglacial periods, how we can reconstruct climate history, and how the Earth is responding to the retreat of the continental glaciers. Video presentation by Meg Rosenburg (AGU Fall Meeting 2013) Post-glacial rebound
Glaciers Sizzle, Squirt Bubbles When Melting To Create Loudest Marine Environment; These Sounds Could Help To Measure Ice Melt By Sreeja VN: Sizzling underwater glacial ice, as it melts into warmer sea water, creates one of the loudest natural marine environments, and the air bubbles that pop during the process could help scientists measure the rate of…

Pine Island Glacier 2013, Nov. 10: This MODIS image taken by NASA’s Aqua satellite on Nov. 10, 2013, shows an iceberg that was part of the Pine Island Glacier and is now separating from the Antarctica continent. What appears to be a connection point on the top left portion of the iceberg is actually ice…

Published on YouTube Nov 21, 2013: This is an animated visualization of the startling decline of Arctic Sea Ice, showing the minimum volume reached every September since 1979, set on a map of New York with a 10km grid to give an idea of scale. It is clear that the trend of Arctic sea ice…
Video published on YouTube Nov 21, 2012 | Article published on July 22, 2013 by Nicole Casal Moore / University of Michigan ANN ARBOR—In events that could exacerbate sea level rise over the coming decades, stretches of ice on the coasts of Antarctica and Greenland are at risk of rapidly cracking apart and falling into…
