Canadian scientists joined a military expedition to the Arctic. What the scientists found is quite disturbing.
Scientists travelling with the troops found major new fractures during an assessment of the state of giant ice shelves in Canada’s far north.
The team found a network of cracks that stretched for more than 10 miles (16km) on Ward Hunt, the area’s largest shelf.
There is a satellite image at the link provided above. 10 mile cracks in sea ice is not indicative of a stable system. Unstable systems don’t move gradually from one state to another. Typically, changes are quick. Don’t be surprised if the break up occurs with minimal signals: the notice has already been given.
