Research suggests the current decline in Arctic sea ice is the longest and steepest in more than 1,400 years.

The study co-written by scientists at the Geologic Survey of Canada uses 69 different information sources to give the most detailed history ever of the northern oceans.

It concludes Arctic waters have lost more ice over the last 50 years than any time since 561 AD.

It also finds that the current trend has lasted longer than any other decline over that period.

The report's authors say the most probable explanation is warmer air and sea temperatures caused by greenhouse-gas-induced climate change.
