Antarctica :

The climate of Antarctica is the coldest on the whole of Earth. Antarctica has the lowest temperature ever recorded: −89.2 °C at Vostok Station. It is also extremely dry (technically a desert), averaging 166 millimetres of precipitation per year. Even so, on most parts of the continent the snow rarely melts and is eventually compressed to become the glacial ice that makes up the ice sheet. Weather fronts rarely penetrate far into the continent.
