[单项选择]Climate Change：The Long Reach
1 Earth is warming Sea levels are rising. There’s more carbon in the air and Arictic ice is melting faster than at any time in recorded history. Scientists who study the environment to better gauge（评估） Earth’s future climate now argue that these changes may not reverse for a very long time.
2 People burn fossil fuels like coal and oil for energy. That burning releases carbon dioxide，a colorless gas. In the air，this gas traps heat at Earth’s surface. And the more carbon dioxide released，the more the planet warms. If current consumption of fossil fuels doesn’t slow，the long-term climate impacts could last thousands of years—and be more severe than scientists had been expecting.Climatologist Richard Zeebe of the University of Hawaii at Manoa offers this conclusion in a new paper.
3 Most climate-change studies look at what’s going to happen in the next century or so.During that time，changes in the planet’s environment could
[单项选择] In the United States the science of climate change still remains a controversial issue. Part of the problems is that it is complex and hard to isolate its parts. We do know how vital it is to life. The atmosphere forms a gaseous, protective envelope around earth protecting the earth from the cold of space, from harmful ultraviolet light, and from all but the largest meteors. After traveling over 93 million miles, solar energy strikes the atmosphere and earth’’s surface, warming the planet and creating what is known as the "bio sphere" which is the region of earth capable of sustaining life. Atmospheric circulation is one important reason that life on earth can exist at higher latitudes because equatorial heat is transported poleward, moderating the climate.
The atmosphere is not just a protector but also a great transporter. The transport of water vapor in the atmosphere is an important mechanism by which heat energy is redistributed poleward. Heat energy absorbed at the equator
