A British explorer has braved sub-zero temperatures to become the first person to swim at the North Pole.
Lewis Gordon Pugh took to the freezing waters on Sunday to highlight the devastating impact of climate change on the natural world.
It took him 18 minutes and 50 seconds to swim 0.6 miles in waters created by melted sea ice at temperatures of 29-degree F — the coldest a human has swum in.
