Lewis Pugh swims the North Pole in a Speedo

In order to raise awareness about climate change Lewis Pugh swam one kilometre across the North Pole with no more protection than a Speedo and a pair of goggles. Keep in mind that the temperature of the salt water at the North Pole, -1.8 Celcius, is below the freezing point of fresh water. This means that his fingers start to freeze from the moment he enters the water.
