Ice shelf breaks off

Much of Canada’s remaining intact ice shelf has broken apart into hulking iceberg islands thanks to a hot summer and global warming, scientists said. Canada’s 4000-yearold Milne Ice Shelf on the northwestern edge of Ellesmere Island had been the country’s last intact ice shelf until the end of last month when satellite photos showed about 43 per cent of it had broken off. The 187sq k undulating white ice shelf of ridges and troughs dotted with blue meltwater had been larger than the District of Columbia but now is down to 106sq k.
