| Ellesmere Island National Park in Canada. Ohio State University researchers and their colleagues have discovered the remains of a mummified forest that lived on the island 2 to 8 million years ago, when the Arctic was cooling. The remains could offer clues to how today’s Arctic will respond to global warming. Photo by Joel Barker, courtesy of Ohio State University. |

| An outcropping of mummified tree remains on Ellesmere Island in Canada. A melting glacier revealed the trees, which were buried by a landslide 2 to 8 million years ago, when the Arctic was cooling. The remains could offer clues to how today’s Arctic will respond to global warming. Photo by Joel Barker, courtesy of Ohio State University. |
