极地科学家发现今年北极无冰

NORTH POLE; POLAR SCIENTISTS REVEAL DRAMATIC NEW EVIDENCE OF
CLIMATE CHANGE: It seems unthinkable, but for the
first time in human history, ice is on course to disappear entirely
from the North Pole this year. The disappearance of the Arctic sea
ice, making it possible to reach the Pole sailing in a boat through
open water, would be one of the most dramatic - and worrying -
examples of the impact of global warming on the planet. Scientists
say the ice at 90 degrees north may well have melted away by the
summer. "From the viewpoint of science, the North Pole is just
another point on the globe, but symbolically it is hugely
important. There is supposed to be ice at the North Pole, not open
water," said Mark Serreze of the US National Snow and Ice Data
Centre in Colorado.
