The CBC reports:
The amount of ice in the Arctic Ocean shrank this summer to the sixth lowest level, but that is much higher than last year’s record low.
The ice cap at the North Pole melts in the summer and grows in winter; its general shrinking trend is a sign of global warming. The National Snow and Ice Data Center said Friday that Arctic ice was at 1.97 million square miles (5.1 million sq. kilometers) when it stopped melting late last week.
