The document discusses how rapidly Arctic sea ice is disappearing due to global warming. It states that Arctic ice may completely vanish by the end of the century according to US scientists. Recent satellite images showed ice volume was at record low levels, with an area over 5 times larger than the UK already lost. The loss of ice is occurring at a rate of 8% per year in a self-perpetuating cycle that could lead to temperatures not seen in over a million years if action is not taken.
