South Pole
In midsummer, as the sun reaches its maximum elevation of about 23.5 degrees, high temperatures at the South Pole in January average at . As the six-month "day" wears on and the sun gets lower, temperatures drop as well: they reach around sunset (late March) and sunrise (late September). In midwinter, the average temperature remains steady at around . The highest temperature ever recorded at the Amundsen–Scott South Pole Station was on Christmas Day, 2011, and the lowest was on June 23, 1982 (for comparison, the lowest temperature directly recorded anywhere on earth was at Vostok Station on July 21, 1983, though was measured indirectly by satellite in East Antarctica between Dome A and Dome F in August 2010). Mean annual temperature at the South Pole is -49.3 °C (-56.7 °F).
Eric Larsen (explorer)
In March 2014, Larsen and Ryan Waters crossed the Arctic Ocean from Northern Ellesmere Island to the geographic North Pole. Larsen has stated that his expedition may be the last ever to the North Pole because of melting ice due to climate change. 
In December 2012, Eric Larsen attempted to be the first person to bike to the South Pole. Departing Hercules Inlet, he made it 175 miles before turning around. In his attempt he set the record for the most miles traveled by bicycle in Antarctica. Daniel P. Burton broke the record in 2014 when he rode his bike to the South Pole.
