[DAILYCALLER] A group of adventurers, sailors, pilots and climate scientists that recently started a journey around the North Pole in an effort to show the lack of ice, has been blocked from further travels by ice.The Polar Ocean Challenge is taking a two month journey that will see them go from Bristol, Alaska, to Norway, then to Russia through the North East passage, back to Alaska through the North West passage, to Greenland and then ultimately back to Bristol. Their objective, as laid out by their website, was to demonstrate "that the Arctic sea ice coverage shrinks back so far now in the summer months that sea that was permanently locked up now can allow passage through."
