A rare hole has opened up in the ozone layer above the Arctic. Scientists say it is due to the result of unusually low temperatures in the atmosphere above the north pole. The hole has reached record dimensions but it isn't dangerous to human unless it moves to south. If it moves towards the south, humans will be at risk of sunburn. But according to current trends, the hole is expected to disappear altogether in a few weeks.
