Fatal Thaw: The Sámi Fight to Preserve an Ancient Culture as the Arctic Warms
One of the world's biggest religions has joined the global debate about climate change—on the side of the angels. After months of anticipation, Pope Francis on Thursday morning released the official text of “Laudato Si’,” or “Praise Be to You,” his encyclical on reversing climate change.
As global temperatures continue to rise on land and at sea, wild animals and plants are on the move worldwide, looking for conditions they can tolerate. These climate change-driven migrations have been starkly visible in the Arctic for years. As ocean ice cover contracts, reports of species like polar bears and walruses being driven onto land have grown over the past decade.
For decades, wind, river and ocean currents have carried DDT, PCBs and other persistent organic chemical pollutants into the Arctic from industrial and agricultural production elsewhere in the world, creating serious health problems for humans and wildlife as they accumulate in the food chain. As the effects of these chemicals have become better understood, nations have moved to phase out and clean up many of them under the international Stockholm Convention.
