Washington — There’s a 50-50 chance that the North Pole will be ice-free this summer, which would be a first in recorded history, a leading ice scientist says.

The weather and ocean conditions in the next couple of weeks wil determine how much of the sea ice will melt, and early signs are not good, said Mark Serreza. He’s a senior researcher at the National Snow and Ice Data Center and [sic] the the University of Colorado in Boulder, Colo.
