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…
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…
