2016高考训练题。阅读理解阅读下列短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项。We know that the earth has become warmer over the last century. The Intergovernmental Panel on Climate Change (IPCC), a group established by the World Meteorological Organization and the United Nations Environment Program, reports that the average surface temperature of the earth has increased during the twentieth century by 0.6°+ 0.2°C.(The + 0.2°C means that the increase might be as small as 0.4°C or as great as 0.8°C). This may seem like a small shift, but although regional and short—term temperatures do fluctuate(变动) over a wide range, global temperatures are generally quite stable. In fact, the difference between today’s average global temperature and the average global temperature during the last Ice Age is only about 5 degrees C. Indeed, it’s warmer today around the world than at any time during the past 1,000years, and the warmest years of the previous century have occurred within the past decade.
We also know that human activities—primarily the burning of fossil fuels—have increased the greenhouse gas content of the earth’s atmosphere significantly over the same period. Carbon dioxide is one of the most important greenhouse gases, which trap heat near the planet’s surface.
The vast majority of climate researchers agree with these overall findings. The scientific disagreements that do still exist primarily concern detailed aspects of the processes that make up these largely accepted general themes.
