The Arctic ice could melt in the summer of 2020, which would allow its navigation, as affirmed an expert from the University of Cambridge, which considers that this may be the most visible impact of climate change. "It's as if the man was removing the cap from the northern part of the planet," said the British media physics professor Peter Wadhams.
This is one of the conclusions of the study conducted Wadhams, the Polar Ocean Physics Group at Cambridge, having considered the measures of the ice collected by the British nuclear submarine HMS Tireless' in 2007 and those taken this year by an expedition led by polar adventurer Pen Hadow.
According to Wadhams, freighters do not have to rely on boats to break the ice to cross the Pacific to the Atlantic Ocean through the so-called Northwest Passage. This route will be ice free for several months a year, which will reduce the over 4,800-km route to do the boats that are in the Far East to Europe via the Suez Canal, the study adds.
"The North Pole will be exposed in ten years. One can navigate in a Japanese freighter car through the North Pole and into the Atlantic. The ice will retreat to an area north of Greenland and Ellesmere Island in 2020" Wadhams said. According to the expert, "the change in the Arctic ice in summer will be the biggest impact that global warming will have on the physical appearance of the planet."
The explorer Pen Hadow and his two teammates-Ann Daniels and Martin Hartley-spent 73 days between 1 March and 7 May of this year walking 450 kilometers in the Arctic while taking measurements. They made holes and 1500 found that the average thickness of ice floes was only 1.8 meters. Hadow said the newspaper 'The Times', techniques for future expeditions to the Arctic during the summer will have to be modified to adapt to frequent open water areas.
