One of nature’s woody behemoths — the North American snow forest — may soon begin shrinking.

The continent’s boreal forest reposes in subarctic latitudes, spanning much of Alaska and Canada. Scientists had previously suggested that its range might shift northward as the climate warms, helping maintain its expansive breadth.
