There is no disputing the real-time effects of climate change. Alaska is warming faster than anywhere else in America, setting off a circumpolar scramble for oil and other resources given up by the melting ice and threatening the livelihood of those who still live off the land and the sea.
“Up here in Alaska, I would say most people do not have an argument that climate change is happening because we see it,” said Douglas Causey, a wildlife biologist at the University of Alaska at Anchorage. “The debate is not whether climate change is happening. The debate is over what’s causing it.”
