Scientists first started to see changes in the Arctic climate in the 1970s and 1980s. And over
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 (
22、冰川) in Greenland and northern Canada are decreasing. In addition, frozen ground in the Arctic has started to melt (融化)Changes in the Arctic climate are important because the Arctic acts as a refrigerator for the rest of the world. The Arctic region gives off more heat to space than it absorbs from o
23、utside, which helps cool the planet. So changes in the Arctic climate could affect the climate in the rest of the world.Predicting the Arctic climate is difficult. Some of the changes in the Arctic could also have positive feedback effects, or effects that reduce the amount of warming. For example,
24、if warm temperatures make the Arctic growing season longer, more plants can survive and take up more carbon from the air.Scientists are studying the many factors that influence Arctic climate to help figure out how feedbacks work and what will happen in the future. Researchers are also investigating
25、 how the changes in the Arctic climate will affect climate in other parts of the world. Scientists study data collected by satellites and at ground stations.语篇解读：本文主要介绍北极变暖的基本情况及其造成的影响。1According to the first paragraph, changes in the Arctic climate _.Astarted to happen in the 1970sBmake the region
