20、the past 30 years, it has warmed more than any other region on the earth. Most scientists agree that Arctic weather and climate are changing because of humancaused climate change.Arctic warming is causing changes to sea ice, snow cover, and the extent of permafrost (永久冻地) in the Arctic. In the first

21、 half of 2010, air temperatures in the Arctic were 4 Celsius warmer than the 1968 to 1996 reference period. Satellite data show that over the past 30 years, Arctic sea ice cover has declined by 30 percent. Satellite data also show that snow cover over land in the Arctic has decreased, and glaciers (
