Why is Arctic ice melting 50 years too fast?
On Aug. 19, 2007, a joint survey by the Japan Agency for Marine-Earth Science and Technology and the Japan Aerospace Exploration Agency revealed that Arctic ice was melting at a far quicker rate than anticipated. What’s particularly alarming about this discovery is that the United Nations‘ scientific models anticipated that the ice levels measured by the Japanese team would not be reached until after 2040 — and possibly not until 2050.

The melting has caused coastal ice in parts of Canada and Alaska to become quite brittle. That ice easily breaks away in large chunks (a process known as calving ) and melts in the open ocean. There’s also less sea ice in t
