Polar ice cap shrinking. Computer illustration of the globe, centred on the North Pole, showing the extent to which the Arctic ice cap (white) shrunk between 1980 and 2015. Perennial ice cover, the ice left at the end of the Arctic summer, has been steadily decreasing since observations began in 1979, at a rate of around 10 per cent per decade. This decrease is attributed to global warming. | |
