Pole of inaccessibility to reach this false northern pole of inaccessibility was made by Sir Hubert Wilkins, who flew by aircraft in 1927. In 1941, the first Soviet expedition using an airplane landed 350 kilometers north of the false northern pole, thus actually becoming the first expedition to reach the real pole. Ignoring Soviet results, Sir Wally Herbert claimed to be the first to reach what was then considered to be the northern pole of inaccessibility on foot, arriving by dogsled in 1968. Explorer Jim McNeill claimed in 2006 that Herbert did not quite make the pole, and launched his own unsuccessful attempt
North Pole heat), rather than at altitude on a continental land mass. Despite being an ice cap, it shares some characteristics with a tundra climate ("ETf") due to the July and August temperatures peaking just above freezing. Winter temperatures at the northernmost weather station in Greenland can range from about , averaging around , with the North Pole being slightly colder. However, a freak storm caused the temperature to reach for a time at a World Meteorological Organization buoy, located at 87.45°N, on December 30, 2015. It was estimated that the temperature at the North Pole was between during the storm. Summer
