Canary in the coal mine – Alaska

At a Senate hearing on Thursday, Sen. Bernie Sanders called Alaska the “canary in the coal mine” on climate change and cited threats to Native American communities from rising seas as a result of global warming.

The village of Newtok, Alaska, near the Arctic Circle, may be underwater by 2017, according to the U.S. Army Corps of Engineers, Sanders noted. More than 180 other native Alaskan villages also are at risk because of climate change, Sanders added.
