A new study led by researchers from ±«ÓćÖ±²„ finds that cold-adapted Arctic species, like the thick-billed murre, are especially vulnerable to heat stress caused by climate change.</p> <p>ā€œWe discovered that murres have the lowest cooling efficiency ever reported in birds, which means they have an extremely poor ability to dissipate or lose heat,ā€ says lead author Emily Choy, a Postdoctoral Fellow in the Natural Resource Sciences Department at ±«ÓćÖ±²„.</p> Tue, 06 Jul 2021 20:42:55 +0000 shirley.cardenas@mcgill.ca 269913 at /newsroom /newsroom/channels/news/narwal-tusks-reveal-mercury-exposure-related-climate-change-330059 <p>In the Arctic, climate change and pollution are the biggest threats to top predators like narwhals. Studying the animalsā€™ 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 14:13:31 +0000 shirley.cardenas@mcgill.ca 257550 at /newsroom /newsroom/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.

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, theĀ GuardianĀ said.</p> Thu, 23 Apr 2020 15:21:53 +0000 amelia.souffrant@mail.mcgill.ca 209119 at /newsroom /newsroom/channels/news/increasingly-mobile-sea-ice-risks-polluting-arctic-neighbours-321204 <p>The movement of sea ice between Arctic countries is expected to significantly increase this century, raising the risk of more widely transporting pollutants like microplastics and oil between neighbouring coastal states, according to new research from ±«ÓćÖ±²„ in collaboration with University of Colorado Boulder, Columbia University, and Arizona State University.</p> Thu, 19 Mar 2020 16:53:17 +0000 shirley.cardenas@mcgill.ca 203540 at /newsroom /newsroom/channels/news/scientists-scan-horizon-future-invasive-species-challenges-268002 <p><span>Shipping and mining in the Arctic.
