Now we know: Canada melt down

Using high tech monitoring devices, including satellite images, scientists have reconstructed a major climate event that occurred on August 13, 2005. That afternoon the forty-one square mile Ayles Ice Shelf broke free of Canada's Ellesmere Island. It now floats free, an ice island off northeastern Canada.

Satellite images and earthquake monitoring devices recorded the event. Nobody lives in the area so it was only digital evidence that existed. Now scientists have visited the newly formed ice island. Its position will be closely watched.

Only five Canadian ice shelves remain connected to land. And measurements show they are 90% smaller than they were a century ago.

At the recent Geophysical Union conference, one report said most Arctic ice will be gone by 2040. Don't buy any real estate near sea level.
