Global warming may or may not be the great environmental crisis of the 21st century, but — regardless of whether it is or isn’t — we won’t do much about it. We will argue over it and may even, as a nation, make some fairly solemn-sounding commitments to avoid it. But the more dramatic and meaningful these commitments seem, the less likely they are to be observed.
Al Gore calls global warming an "inconvenient truth," as if merely recognizing it could put us on a path to a solution. But the real truth is that we don’t know enough to relieve global warming, and — without major technological breakthroughs — we can’t do much about it.
From 2003 to 2050, the world’s population is projected to grow from 6.4 billion to 9. 1 billion, a 42% increase. If energy use per person and technology remain the same, total energy use and greenhouse gas emissions(mainly, CO

)will be 42% higher in 2050. But that’s too low, because societies that grow richer use more energy. We need economic growth unless we condemn the world’s poor to their present poverty and freeze everyone else’s living standards. With modest growth, energy use and greenhouse emissions more than double by 2050.
No government will adopt rigid restrictions on economic growth and personal freedom(limits on electricity usage, driving and travel)that might cut back global warming. Still, politicians want to show they’re "doing something. " Consider the Kyoto Protoco(京都议定书). It allowed countries that joined to punish those that didn’t. But it hasn’t reduced CO
2
emissions(up about 25% since 1990), and many signatories(签字国)didn’t adopt tough enough policies to hit their 2008—2012 targets.
The practical conclusion is that if global warming is a potential disaster, the only solution is new technology. Only an aggressive research and development program might find ways of breaking our dependence on fossil fuels or dealing with it.
The trouble with the global warming debate is that it has become a moral problem when it’s really an engineering one. The inconvenient truth is that if we don’t solve the engineering problem, we’re helpless.
What is said about global warming in the first paragraph?
选项
A、It may not prove an environmental crisis at all.
B、It is an issue requiring worldwide commitments.
C、Serious steps have been taken to avoid or stop it.
D、Very little will be done to bring it under control.
答案
D
解析
判断题。根据题干将本题定位到文章首段。该段首句提到,不管全球变暖是否是21世纪最大的环境危机,我们都不会为之付出太多。D项与第二个破折号后的句子we won’t domuch about it意思一致,故为正确答案。
