Would some degree of warming be bad for most societies and natural environments? "During the 20th century, " writes Dr. Patrick Michaels, "we have already proceeded more than half way to doubling the natural carbon dioxide greenhouse effect. Here is what resulted: Life expectancy doubled in the free and developed world. The developing world is catching up as their emissions rise. Corn production peracre increased fivefold. The growing season in the coldest latitudes increased slightly, but enough to increase greenness by 10 percent. "
The small amount of warming that occurred during the past century consisted primarily of increased minimum temperatures at night and during winters. This means higher average temperatures, should they occur, would not result in more daytime evaporation, which some claim would lead to droughts and desertification. Warmer winters would mean longer growing seasons and less stress on most plants and wildlife, producing a substantial benefit for the global ecosystem. Finally, past warming has been accompanied by increased cloudiness, a phenomenon also predicted by most global climate models. This means a warmer world would probably be a wetter world, which once again would be beneficial to most plant and animal life.
Ex-Vice President Al Gore claimed that " hundreds of millions of people may well become even more susceptible to the spread of diseases when populations of pests, germs, and viruses migrate with the changing climate patterns". Gore has also claimed that global warming will cause floods, droughts, heavy rainfall, forest fires, retreating glaciers, and heavier snowfall. In addition to often being at odds with each other, Gore’s claims are at odds with most scientific research. The two historical epidemics described by Gore to validate his prediction were unrelated to climate change. The Black Death, for example, was transmitted by rats, which flourish in cool as well as warm climates. Cholera has been a threat in warm as well as cold climates, and is readily brought under control by treating water supplies with chlorine(氯).
The latest research suggests that sea levels would decline, not rise, if temperatures rise, due to increased evaporation from the oceans and subsequent precipitation over land. Increasing polar temperatures by a few degrees would not cause ice or snow to melt because the original temperatures are so low that an increase of a few degrees would leave them well below freezing. The IPCC itself found " inadequate data to determine whether consistent global changes in climate variability or weather extremes have occurred over the 20th century," with some regions exhibiting greater variability and others less. In short, a slightly warmer world would probably be greener and a little cloudier than our world today, but otherwise not much different. [br] What’s Dr. Patrick Michaels’ opinion towards global warming?
选项
A、It can prolong the grow season in the low latitudes.
B、It will shorten people’s life span.
C、Some degree of it can benefit human.
D、Some degree of it can cause a reduction in grain yield.
答案
C
解析
观点态度题。第一段Here is what result后全部是Patrick Michaels对一定程度的全球变暖造成的影响的观点:人们的平均寿命延长,作物增产,最冷的纬度地区的种植季节有所延长。故可以看出他认为一定程度的全球变暖是会有益于人类的,[C]项是对文意的正确理解,故为答案。文中说最冷纬度地区的种植季节可以增加,根据常识判断最冷纬度区应该在高纬度区,而非低纬度区,故[A]项错误。[B]、[D]正好与文意相反,故也都排除。
