Arctic ice-melting this summer has already been so extreme that it has easily passed the last record low, set in 2007.
Sea ice cover in the Arctic has fallen to its lowest level since satellite records began 33 years ago, scientists said recently, prompting experts to warn the world had entered “uncharted territory” in the rate of climate change.
