Arctic sea ice shrinks to record low - NewsX

The Arctic ice cap has shrunk to lowest extent ever, surpassing a record set only five years ago, signalling the long-term impact of global warming. With possibly two weeks' further melt likely before the ice reaches its minimum extent and starts to refreeze ahead of the winter, satellites showed it had shrunk to 4.1 million sq km on Sunday. The record is widely seen by scientists at the NSIDC and elsewhere as a strong signal of long-term climate warming. Arctic sea ice follows an annual cycle of melting through the warm summer months and refreezing in the winter. It has shown a dramatic overall decline over the past 30 years.
