What has the NASA report revealed?
The vast arctic ice cap is shrinking so fast it could melt away completely before the end of this century. These are the dire warnings from NASA scientists who say they are stunned by the findings. They claim more ice on the North Pole is disappearing every year because of the climate changes. BBC’s science correspondent Christine McGourty reports:
A vast frozen wilderness, but the climate here is changing, and for the wildlife that could be devastating. Floating ice provides polar bears with a platform for hunting seals but new satellite data show sea ice melting at a rate of 8% every decade. This map shows how sea ice changes with the seasons, spreading in the cold arctic winter and then decreasing in the summer months to a September low. But this year, there’s 500,000 square miles less than in the 1970s.
选项
A、The global warming is slowing down.
B、The world’s climate is changing dramatically.
C、The ice around the arctic is disappearing very quickly.
