"A small but dangerous parasite, the winter tick, is spreading north and west as winters become shorter and now is knocking at Alaska's border. The winter tick, which has already devastated moose populations in New England and the upper Midwest, has been confirmed in Canada's Yukon Territory and in the Northwest Territories, where it's infecting elk, mule deer and some moose."

"Emissions from thawing permafrost are now outpacing the uptake of carbon dioxide during the growing season, a new study suggests".

"The Supreme Court on Monday refused to hear a challenge to the U.S. Fish and Wildlife Service’s decision to designate 187,000 square miles of Alaska’s coast and waters a critical habitat for the threatened polar bear."

"President Trump signed an executive order [Friday] that reverses a ban on drilling in much of the Arctic and ensures a legal fight over an obscure provision of the Outer Continental Shelf Lands Act."

"As the underwater methane leak in Cook Inlet, Alaska continues well into its third month, even basic environmental monitoring has been impossible because of ice cover. The ice also prevents any repair to the pipeline or response to the leak."
