News Update 1: Strong southerly winds have melted a piece of Arctic ice in the Beaufort Sea the size of Texas, making it likely the Northwest Passage will be navigable for the second summer in a row. While end-of-summer ice melt is not expected to surpass last year’s record, it is likely to be a close second and Beaufort is open further north than ever before, one-third of the way from Alaska to the North Pole. The melting of the large chunk of ice is a sure sign of global warming, said Mark Serreze, of the National Snow and Ice Data Center. Elsewhere in the Arctic, record high temperatures forced closure of most of Auyuittuq National Park on Canada's Baffin Island. Melting permafrost, erosion and flooding led to evacuation by helicopter of 21 park visitors. Temperatures reached into the 80s for two weeks. The July average is usually 57.
