Lake ice is also thinner each winter.The scientists surveyed 402 lakes on the North Slope，where permafrost (permanently frozen ground)and shallow lakes dominate the area.In 2011, the lake ice was 38 percent thinner than in 1950, and 22 percent fewer lakes froze through to their bottoms. “When we saw the actual numbers we were shocked at how dramatic the change has been，” lead study author Cristina Surdu, of the University of Waterloo in Canada，said in a statement.Surdu and her coauthors analyzed the changes in lakeice thickness and ice cover with satellite images and climate model simulations(satellite images are only available from 1991)． The climate models suggest the Arctic lakes froze almost six days later and broke up about 18 days earlier in the winter of 2011 pared with the winter of 1950.“The changes in ice and the shortened winter affect Northern munities that depend on ice roads to transport goods，”Surdu said.For example, every winter, oil panies build roads over frozen lakes to carry supplies to Prudhoe Bay. “The dramatic changes in lake ice may also contribute to further warming of the entire region, because open water on lakes contributes to warmer air temperatures，” Surdu said.The Arctic is warming twice as fast as the rest of the planet, for reasons that may include its layered atmosphere, which traps heat, and the loss of sea ice and snow cover, which help reflect the suns energy when present. 【語篇解讀】　本文主要講述北極湖冰的變化及其帶來的影響。 1．What does the text mainly tell us?
