Arctic sea ice could break apart completely at the North Pole this year, allowing ships to sail over the normally frozen top of the world.
The potential landmark thaw - the first time in human history the pole would be ice-free - is a stark sign of global warming, according to an article Friday on the web site of the The Independent, a London newspaper.

"First time in human history" may be stretching it a little. Antarctica was ice free as recently as 4000 BC. There are surviving maps recopied at Alexandria that show it as two islands. So it's not much of a stretch to suspect that the Arctic was also ice free at the time.
