This study instead investigates influences of Arctic sea ice loss on the Eastern Hemisphere westerly wind on the poleward side of the polar front jet (PFJ), which has significantly weakened in winter but strengthened in summer since 1980s. Observational analyses indicate that the Eastern Hemisphere...
Arctic sea ice has reached its minimum extent (覆盖面积) for the year 2012,setting a record for the lowest summer cover since satellite data collection began.The sea ice extent has fallen to 3.41 million sq km on 18 September-50% lowerthan the 1979-2000 average.On August 26, sea ice ext...

Arctic sea ice has been steadily decreasing since the beginning of satellite records in 1979, but a new study comes with a warming prediction: By the end of this century, Arctic sea ice may disappear during the summer, which could drive polar bears and other ice-dependent species extinction....

1That Arctic sea ice is disappearing has been known for decades. The underlying cause is believed by all but a handful of climatologists to be global warming brought about by greenhouse-gas emissions. Yet the rate the ice is vanishing confuses these climatologists’ models. These predict that if...
根据第二段中的Throughout the spring and summer, Arctic seaice melted away faster than it usually does ,causing the largest loss of Arctic sea ice coversince satellite records began in the 1 970s. This year's minimum was reached on September15, at 3.74 million m2 compared with the previous...
The decline in sea ice seen in the Arctic in recent decades has been linked by scientists to the spread of a deadly virus in marine (海洋的) mammals. Researchers found that Phocine distemper virus (PDV) had spread from animals in the North Atlantic to populations in the North Pacific. Ac...
Beyond the disappearing ice cover, the remaining ice is also becoming less reflective as warming temperatures and increased rainfall create thinner and wetter ice and more melt ponds that reflect less solar radiation. This effect has been most obvious in the Arctic, where sea ice has become less...
Huge Waves Destroying Arctic Ice Faster than Expected Ice covers much of the Arctic Ocean(北冰洋).Some pieces of ice are huge,like moving islands.As temperatures have increased,however,some of the ice has begun to disappear.Scientists have discovered huge waves(海浪) in the arcti...
