Studying the animals’ tusks reveals that diet and exposure to pollution have shifted over the past half century in response to sea-ice decline. Human emissions have also led to a sharp rise in the presence of mercury in recent years, according to an international team of researchers.</p> Mon, 29 Mar 2021 14:20:29 +0000 webfull 169475 at /channels /channels/channels/news/arctic-researcher-wins-prestigious-2020-loreal-canada-women-science-research-excellence-fellowship-326444 <p><strong>Emily Choy</strong> [Post Doctoral Fellow, NRS.

Sea ice is frozen ocean water that melts each summer, then refreezes each winter. The amount of summer sea ice in the Arctic has been steadily shrinking over the past few decades because of global warming. Since satellite records began in 1979, summer Arctic ice has lost 40% of its area and up to 70% of its volume, the Guardian said.</p> Thu, 23 Apr 2020 15:21:54 +0000 webfull 160292 at /channels /channels/channels/news/north-pole-will-be-ice-free-summer-321739 <p>Summer Arctic sea-ice is predicted to disappear before 2050, resulting in devastating consequences for the Arctic ecosystem.
