Ellesmere Island was once entirely ringed by a single enormous ice shelf that broke up in the early 1900s.

All that is left today are the four much smaller shelves.

Ecosystems 'face extinction'

During the last century when ice shelves would break off, thick sea ice would eventually form in their place.
What caused the warming in the early 1900's? Must have been all them SUV's.
So, according to this article, thin ice breaks off and floats away and is then replaced by thick ice. How would global warming cause this?
