Even today, less than one-tenth of Arctic sea ice passing through the Fram Strait is over 4 meters thick. The unprecedented lows reached in 2005, and again in 2007, marked a transition point across the Arctic Basin, shifting this ice-capped environment to a thinner, more vulnerable landscape. This shift to thinner ice makes it easier for large sheets of sea ice, or &#8220;ice floes&#8221; to enter the Strait and melt in warm Atlantic waters, preventing the winter growth of sea ice from lasting through the summer. Overall, ice floes now spend one-third less time in the Arctic since 2007. These findings highlight the existence of thresholds and &#8220;non-linear&#8221; changes in cryosphere, and the very long-lasting impacts of current global warming on the world&#8217;s ice stores.<\/p>\n<p><a href=\"https:\/\/www.nature.com\/articles\/s41586-022-05686-x\">https:\/\/www.nature.com\/articles\/s41586-022-05686-x<\/a><\/p>","protected":false},"excerpt":{"rendered":"<p>Nature, 15 March 2023 An examination of decades of measurements from the Fram Strait concluded that Arctic sea ice crossed an essentially irreversible threshold of loss between 2005-2007, when fully half of the Arctic&#8217;s thick multi-year ice disappeared &#8212; and has never recovered.
