The heatwave that swept across much of Europe over July has made its way to Greenland, accelerating the melting of the island’s ice sheet. Scientists from the Danish Meteorological Institute said that since 1 June, the ice sheet has lost 240 gigatonnes, compared to a loss of 290 gigatonnes in the whole of 2012. The melting of ice in Greenland alone will contribute between 5 and 33 centimetres to rising global sea levels by the year 2100.
