Leading independent ice scientists from the University of Cambridge joined the Greenpeace ice breaker Arctic Sunrise on an expedition to test Arctic
sea ice thickness, in a year that could mark the lowest sea ice minimum on record. Temperature rise in the Arctic is among the fastest on Earth due to emissions of carbon dioxide from oil, coal and gas. As climate change causes the Arctic’s sea ice cover to recede, the ice’s cooling effect caused by its reflecting solar radiation back into space is reduced, causing temperatures to rise even faster.
