The Arctic is rapidly changing from the climate crisis, with no "new normal," scientists warn. Wildfires and permafrost thaw are making the tundra emit more carbon than it absorbs. From Alaska to Siberia, the Arctic is changing so rapidly that there is no "normal" there now, scientists warn. AdvertisementThe Arctic tundra now releases more carbon than it naturally draws down from the sky, as wildfires burn down its trees and permafrost thaw releases potent gases from its soil. The increase in average temperatures is changing weather and landscapes in the Arctic, speeding up the climate crisis worldwide.
