2、ming over the past century Soot in the higher latitudes of the Earth ， where ice is more common ， absorbs more of the sun's energy and warmth than an icy,white background Dark-colored black carbon ， or soot ， absorbs sunlight, while lighter colored ice reflects sunlight "ThisSoot in areas w

3、ith snow and ice may play an important role in climate change Also ，if snow and ice covered areas begin melting ， the warming effect increases ，as the soot becomes more concentrated on the snow surfaceprovides a positive feedbackas glaciers and ice sheets melt，they tend to get even dirtier,"sai

4、d DrJames Hansen ，aresearcher at NASA's Goddard Institute for Space StudiesNewYorkHansen found soot's effect on snow albedo(solarenergy reflected back to space)，which may be contributing totrends toward early springs in the Northern Hemisphere， suchas thinning Arctic sea ice ， melting glacie

5、rs and permafrost Soot also is believed to play a role in changes in the atmosphere above the oceans and land"Black carbon reduces the amount of energy reflected by snow back into space ，thus heating the snow surface more than if there were no black carbon， "Hansen said Soot'sincreased

6、 absorption of solar energy is especially effective in warming the world's climate"This forcing is unusually effective， causing twice asmuch global warming as acarbon dioxide forcing of the samemagnitude "Hansen noted Hansen cautioned ，although the role of soot in altering global clima

7、te is substantial， it does not alter the fact thatgreenhouse gases are the primary cause of climate warming during the past century Such gases are expected to be thelargest climate forcing for the rest of this centuryThe researchers found that observed warming in theNorthern Hemisphere was large in

8、the winter and spring at middle and high latitudes These observations were consistent with the researchers'climate model simulations which showedsome of the 1argest warming effects occurred when there were heavy snow cover and sufficient sunlight1 Paragraph 3 _ 2 Paragraph 4 _ 來(lái)源：考試大3 Paragraph
