The global averagesurface temperature rose 0.6 to 0.9 degrees Celsius (1.1 to 1.6°F) between 1906 and 2005, and the rate of temperature increase has nearly doubled in the last 50 years. Temperatures are certain to go up further.Earth’s natural greenhouse effect Earth’s temperature begins with the Sun. Roughly 30 percent ofincoming sunlight is reflected back into space by bright surfaces like clouds and ice. Of the remaining 70percent, most is absorbed by the land and ocean, and the rest is absorbed by the atmosphere. The absorbedsolar energy heats our planet. As the rocks, the air, and the seas warm, they radiate “infrared radiation). From the surface, this energy travels into the atmosphere where much of it is absorbedby water vapor and long-lived greenhouse gases such as carbon dioxide and methane. When they absorbthe energy radiating from Earth’s surface, microscopic water or greenhouse gas molecules turn into tiny heaters— like the bricks in a fireplace, they radiate heat even after the fire goes out. They radiate in alldirections. The energy that radiates back toward Earth heats both the lower atmosphere and the surface,enhancing the heating they get from direct sunlight. This absorption and radiation of heat by the atmosphere—the natural greenhouse effect—is beneficial for life on Earth. If there were no greenhouseeffect, the Earth’saverage surface temperature would be a very chilly -18°C (0°F) instead of the comfortable 15°C (59°F) that it is today.What has scientists concerned now is that over the past 250 years, humans have been artificiallyraising the concentration of greenhouse gases in the atmosphere at an ever-increasing rate, mostly byburning fossil fuels, but also from cutting down carbon-absorbing forests. Since the Industrial Revolutionbegan in about 1750, carbon dioxide levels have increased nearly 38 percent as of 2009 and methanelevels have increased 148 percent.II.拓展提高书面表达如何解决全球变暖是我们全人类共同面临的一个难题。
