A group of Arctic explorers has made the grueling journey to the North Pole and drilled a hole in the ice to take the first ever sample of ocean water at the pole in an effort to better understand the impacts of climate change. The explorers, part of a group called the Catlin Arctic Survey, completed the sampling expedition after failing to last year, reported the Guardian. The team reached the geographic North Pole on May 12 after a 60-day trek across the frigid Arctic ice.
