In 2007 climate scientists were shocked when the regular summer retreat of the Arctic’s sea ice went far farther than they had ever seen before. In the spring of that year ice covered just under 15m km2 (5.8m square miles) of ocean—an area 90% as big as Russia. By mid-September, when it reached its minimum, there were just 4.17m km2 left. That is about the area of the European Union minus Greece. Since 1979, when satellites made such measurements possible, there had been no melt like it.
