Soot and Snow: a Hot Combination 1. New research from NASA scientists suggests emissions of black soot alter the way sunlight reflects off snow. According to a computer simulation, black soot may be responsible for 25 percent of observed global warming over the past century. 2. 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. 3. Soot in areas with snow and ice may play all 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 surface. "This provides a positive feedback, as glaciers and ice sheet smelt, they tend to get even dirtier," said Dr. James Hansen, a researcher at NASA’s Goddard Institute for Space Studies, New York. 4. Hansen found soot’s effect on snow albedo (solar energy reflected back to space), which may be contributing to trends toward early springs in the Northern Hemisphere, such as thinning Arctic sea ice, melting glaciers and permafrost. Soot also is believed to play a role in changes in the atmosphere above the oceans and land. 5. "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’s increased absorption of solar energy is especially effective in warming the world’s climate. "This forcing is unusually effective, causing twice as much global warming as a carbon-dioxide forcing of the same magnitude," Hansen noted. 6. Hansen cautioned, although the role of soot in altering global climate is substantial, it does not alter the fact that greenhouse gases are the primary cause of climate warming during the past century. Such gases are expected to be the largest climate forcing of the rest of this century. 7. The researchers found that observed warming in the Northern Hemisphere was large in the winter and spring at middle and high latitudes. These observations were consistent with the researchers’ climate model simulations, which showed some of the largest warming effects occurred when there were heavy snow cover and sufficient sunlight. A. Soot’s Role in Changes in the Climate and the Atmosphere B. Observations of Warming in the Northern Hemisphere C. Explanation of Increased Warming Effect Caused by Soot D. Effort to Reduce Snow Albedo E. Ways to Reduce Soot Emission F. Greenhouse Gases as the Main Factor of Global Warming Paragraph 6 ______

Common Problems, Common Solutions The chances are that you made up your mind about smoking a long time ago—and decided it’s not for you. The chances are equally good that you know a lot of smokers—there are, after all about 60 million of them, work with them, and get along with them very well. And finally it’s a pretty safe bet that you’re open-minded and interested in all the various issues about smokers and nonsmokers—or you wouldn’t be reading this. And those three things make you incredibly important today. Because they mean that yours is the voice—not the smoker’s and not the anti-smoker’s—that will determine how much of society’s efforts should go into building walls that separate us and how much into the search for solutions that bring us together. For one tragic result of the emphasis on building walls is the diversion of millions of dollars from scientific research on the causes and cures of diseases which, when all is said and done, still strike the nonsmoker as well as the smoker. One prominent health organization, to cite but a single instance, now spends 28 cents of every publicly contributed dollar on "education" (much of it in anti-smoking propaganda) and only 2 cents on research. There will always be some who want to build walls, who want to separate people from people, and up to a point, even these may serve society. The anti-smoking wall-builders have, to give them their due, helped to make us all more keenly aware of choice. But our guess, and certainly our hope, is that you are among the far greatest number who know that walls are only temporary at best, and that over the long run, we can serve society’s interest better by working together in mutual accommodation. Whatever virtue walls may have, they can never move our society toward fundamental solutions. People who work together on common problems, common solutions, can. According to the passage, the writer looks upon the anti-smoking wall-builders’ actions ______.
