In Greenland’s Melting Ice, A Warning on Hard Climate Choices…

Greenland is melting at an unprecedented rate, causing vast quantities of ice to disappear and global sea levels to rise. The fate of the ice sheet is not sealed, but unless CO2 emissions are sharply cut, the long-term existence of Greenland’s ice is in doubt… Read the article here at Yale Environment 360: https://e360.yale.edu/features/in-greenlands-melting-ice-a-warning-on-hard-climate-choices Advertisements

Is Warming Bringing a Wave of New Diseases to Arctic Wildlife?…

Intro: Rapid warming and vanishing sea ice in the Arctic has enabled new species, from humpback whales to white-tailed deer, to spread northward. Scientists are increasingly concerned that some of these new arrivals may be bringing dangerous pathogens that could disrupt the region’s fragile ecosystems… Read the full article here at Yale Environment 360: https://e360.yale.edu/features/is-warming-bringing-a-wave-of-new-diseases-to-arctic-wildlife

As Greenland Warms, Nature’s Seasonal Clock Is Thrown Off-Kilter…

For millennia, ecosystems in Greenland and throughout the Arctic have been regulated by seasonal changes that govern the greening of vegetation and the migration and reproduction of animals. But a rapidly warming climate and disappearing sea ice are upending that finely tuned balance… This full article is at Yale Environment 360, read it here: https://e360.yale.edu/features/as-greenland-warms-natures-seasonal-clock-is-thrown-off-kilter

‘Archived’ heat has reached deep into the Arctic interior, researchers say…

Summary:  Arctic sea ice isn’t just threatened by the melting of ice around its edges, a new study has found: Warmer water that originated hundreds of miles away has penetrated deep into the interior of the Arctic… Read the article here at sciencedaily.com: https://www.sciencedaily.com/releases/2018/08/180829143836.htm

‘Abrupt thaw’ of permafrost beneath lakes could significantly affect climate change models…

Summary:  Methane released by thawing permafrost from some Arctic lakes could significantly accelerate climate change, according to a new study. Unlike shallow, gradual thawing of terrestrial permafrost, the abrupt thaw beneath thermokarst lakes is irreversible this century. Even climate models that project only moderate warming this century will have to factor in their emissions, according […]
