Alligators in the Arctic and how to avoid them : science, economics and the challenge of catastrophic climate change

"Ellesmere Island is in the very far north of Canada, above the arctic circle. It lies just to the west of Greenland, and like its bigger neighbor it is almost entirely glaciated. If you are on your way to the North Pole by way of Canada, this will probably be your last stop. Few scientists had made their way to Ellesmere when Mary Dawson, a paleontologist at the Carnegie Museum of Natural History, launched her first expedition there in 1973. Dawson, 42 at the time, was fascinated by the possibility that there had once been a land bridge between North America and Europe, and she hoped to find evidence that terrestrial species had migrated across it millions of years ago. Accompanied by a coworker, she hauled her gear to a remote camp and began scouring the desolate, frozen territory for fossil remains."
