Climate change: Arctic permafrost now melting at levels not expected until 2090.

A "series of anomalously warm summers” has dramatically accelerated melting rates at three sites despite average annual ground temperatures remaining low. Ponds and hillocks have formed as a result.  

Permafrost hs begun thawing in the Canadian Arctic more than 70 years early because of climate change, according to new research. 

It had been thought that the permafrost - ground that remains frozen for at least two years - would remain until at least 2090.
