North American glaciers melting much faster than 10 years ago – study

Satellite images show glaciers in US and Canada, excluding Alaska, are shrinking four times faster than in previous decade

Glaciers in western North America, excluding Alaska, are melting four times faster than in the previous decade, with changes in the jet stream exacerbating the longer-term effects of climate change, according to a new study.

The retreat hasn't been equal in the US and Canada. The famous alpine ice masses in the Cascade Mountains in the north-west US have largely been spared from the trend.
