Sea level rise: New iceberg theory points to areas at risk of rapid disintegration
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…
ESA Cryosat Animation of Arctic Sea Ice Thickness 2010-2013 with commentary
Via ESA, 11 September 2013: Offering new insights into our fragile polar regions, ESA’s CryoSat mission has provided three consecutive years of Arctic sea-ice thickness measurements, which show that the ice continues to thin. Although satellites have witnessed a downward trend in the extent of sea ice over the last two decades, it is essential to…
