The battle to prevent or at least slow global warming has intensified in the past year as scientists have learned more about the magnitude of the problem. One of the leading climate experts, Inez Y. Fung, director of the Atmospheric Sciences Center at the University of California, Berkeley, recently showed that the earth may soon lose its ability to absorb much of the greenhouse gas that is raising temperatures. The oceans and continents currently soak up about half the carbon dioxide produced by the burning of fossil fuels. In the oceans, the gas combines with water to form carbonic acid; on land, plants take in more carbon dioxide and grow faster.
But computer modeling done by Fung and her colleagues indicates that these
carbon sinks
will become less effective as the earth continues to warm. For example, as the tropics become hotter and drier in the summer, plants will reduce their respiration of carbon dioxide to avoid water loss. Atmospheric measurements over the past decade have confirmed this effect. If the oceans and land take in less carbon dioxide, more will remain in the atmosphere and global warming could accelerate catastrophically. Despite these warning signs, the government administration has opposed approval of the Kyoto Protocol, the international treaty mandating reductions in greenhouse gas emissions. But nine states in the northeastern U.S. are attempting to sidestep the federal government’s opposition by taking action on their own. Last August the group reached a preliminary agreement to reduce emissions of carbon dioxide by 10 percent by 2020. The plan requires approval by the state legislatures, but environmentalists are already hoping that other regions of the U.S. will follow suit. If adopted nationwide, the proposal would lower greenhouse gas emissions by roughly as much as the Kyoto Protocol would have.
Steve Howard, chief executive of the Climate Group, is tackling the global-warming problem from a different angle. Founded in 2004, the Climate Group is a coalition of corporations and local governments that have voluntarily committed to reducing their greenhouse gas emissions. Members include oil giant BP (British Petroleum Co. PLC), drug-maker Johnson & Johnson, and Starbucks. Businesses in the Climate Group have discovered that improvements in energy efficiency can enhance profits as well as cut fossil-fuel emissions; BP, for instance, slashed its energy bills by $650 million over 10 years. "We have seen important evidence about successful emission reduction scattered here and there in the most surprising places all over the globe," Howard says. "We are working to bring all of it together so that it forms a body of evidence."
Which of the following is true of the reactions of authorities to the global warming?
选项
A、The government decides to rewrite the Kyoto Protocol.
B、Parts of the U.S. will follow the federal government’s advice.
C、The U.S. has approved the new plan of gas emissions.
D、Nine states in the U.S. will paddle their own canoe.
答案
D
解析
事实细节题。根据reactions of authorities可知需到后两段寻找答案。第三段说到美国东北部的9个州决定单独采取行动,可知D项为正确选项。
