Arctic report card



A “report card” that tracks multiple changes in the Arctic environment has found that while some indicators show signs of stabilization, other changes are dramatic. In 2007, the central Arctic region lost almost 40 percent of its summertime sea ice, relative to amounts of Arctic sea ice in the 1980s, according to the report card, organized by NOAA and issued on 17 October by an international team of scientists. The report also found that permafrost temperatures are stabilizing in North America and Eurasia but permafrost melt remains a key problem, and that changes in Arctic animal populations have been mixed over decades. “This annual update provides key information to decision makers and the scientific community on changes that are taking place in the Arctic now,” said Richard Spinrad, NOAA assistant administrator for oceanic and atmospheric research.
