The Arctic ice is melting faster than predicted. In August 2012, calculations based on the satellite imagery indicated that the summer sea ice loss was 50 per cent higher than earlier estimates. 1 Scientific evidence now suggests that the Arctic, by the middle of the century, will be ice free in the summer. Scientists call it the ‘Arctic amplification’—the reduction in the ice cover not only reduces the reflection of the sunlight but also increases the absorption of heat as the darker water is exposed.
