　　More ice melted from the surface of the Greenland Ice Sheet this year than ever before recorded, report scientists from the University of Colorado. The same team found that the extent of Arctic sea ice reached the lowest level in the satellite record in 2002, offering further proof that climate change is already changing the Arctic.

　　Researchers from the University of Colorado (UC) say that the speeding up melting appears to be linked to changes in Northern Hemisphere(北半球) atmospheric circulation (环流) patterns. The study also found temperatures during the summer of 2002 were warmer than usual over much of the Arctic Ocean.

　　“It is likely that sea ice extent will continue to decline over the 21st century as the climate warms,” researchers added. “With these trends (趋势), we may see a 20 percent reduction in the yearly average sea ice by 2050, and by then there might be no ice at all during the summer months.”

　　The report was released on Saturday at the yearly fall meeting of the American Geophysical Union, just one week after an announcement by the National Aeronautics and Space Administration (NASA) that sea ice is melting about nine percent faster than earlier research had showed, and could disappear entirely by the end of this century.

　　“This trend of disappearing arctic sea ice is one example of the environmental damage that can be linked to carbon dioxide emissions,” said Morgan. “When we have the means to reduce CO₂ emissions and prevent further damage, we should do our best. National leaders must act now to improve energy efficiency and increase the use of renewable energy sources, like wind and solar, before it's too late.”

　　UC scientists judge that a change in the Greenland climate toward warmer conditions would lead to an increase in the rate of sea level rise, which will bring disasters to the human beings.
