ENVIRONMENT: Polar swimmer demonstrates ice cap melting

Lewis Gordon Pugh, known as 'The Polar Bear' because of his ability to swim in icy waters, has swum in the Arctic ocean to raise awareness of climate change. He performed the stunt to demonstrate that the same waters were frozen ten years ago. Pugh is able to swim in temperatures which would kill other people because of his ability to control his body temperature.
