A new analysis shows that the cause may instead be reduced snow accumulation in the Mackenzie delta each winter; without as much snow to reflect sunlight, the ice is easier to break up in spring. If the same phenomenon applies to sea ice, it could explain why sea ice is disappearing so much faster than predicted.<\/p>\n<p><!--more--><\/p>\n<p><span style=\"text-decoration: underline;\"><a href=\"http:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/2013GL058761\/abstract\" target=\"_blank\">Original research paper<\/a><\/span>\u00a0published in the\u00a0journal\u00a0<em>Geophysical Research Letters<\/em>\u00a0on\u00a0<strong>March 10, 2014<\/strong>.<\/p>\n<p><span style=\"text-decoration: underline;\"><strong>Names and affiliations of selected<\/strong><strong>\u00a0authors<\/strong><\/span><\/p>\n<h4><a href=\"http:\/\/www.sfu.ca\/geography\/people\/faculty\/lance-lesack\" target=\"_blank\">Lance Lesack<\/a>, Simon Fraser University<\/h4>\n","protected":false},"excerpt":{"rendered":"<p>As the climate warms, scientists predict more precipitation, higher river flows and earlier ice breakup in the spring.
