‘Unprecedented’ ice loss as Greenland breaks record

Scientists say the loss of ice in Greenland lurched forward again last year, breaking the previous record by 15%.

A new analysis says that the scale of the melt was “unprecedented” in records dating back to 1948. High pressure systems that became blocked over Greenland last Summer were the immediate cause of the huge losses.

Using data from the Grace and Grace-FO satellites, as well as climate models, the authors conclude that across the full year Greenland lost 532 gigatonnes of ice – a significant increase on 2012.

The researchers say the loss is the equivalent of adding 1.5mm to global mean sea levels, approximately 40% of the average rise in one year.
