求几篇有关全球变暖的英语阅读理解（初中级别的）
Global warming may or not be the great environmental crisis of the 21st century, but—regardless of weather 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 in on a path to a solution. But the real truth is that we don't know enough to believe global warming, and — withour major technological breakthroughs — we can't do much about it.
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 Protocol. It allowed countries that joined to punish those that didn't. But it hasn't reduced CO? emissions (up about 25% since 1990), and many signatories didn't adopt tough enough policies to hit their 2008 — 2012 targets.
The practical conclusion is that if global warming is a potentail 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 engineering one. The inconvenient truth is that if we don't solve the engineering problem, we're helpless.
全球变暖有可能是21世纪巨大的环境危机，也有可能不是，但是无论它是或不是我们对此都无能为力。我们会争论不休，作为一个国家，或许会做出一些听起来相当认真的承诺来避免这一危机。但是这些承诺看起来越是令人印象深刻、越是有意义，就越是不太可能被遵守。
戈尔称全球变暖是一个“让人感到麻烦的事实”，似乎只要认识到它的存在就可以把我们带往一条解决问题的途经上去。但是真正的事实是，我们没有掌握足够的知识去缓解全球变暖，并且如果没有重大的技术突破，我们对此也束手无策。
没有哪个政府会对经济增长和个人自由（限制电力的使用，驾驶和旅游）采取严格的限制令，虽然这样的限制可以缓解全球变暖。即便事实如此，执政者们还是想表明他们在“采取措施”。就拿《京都协议》来说吧，它允许其成员国惩罚非成员国。但是它并没有起到减少二氧化碳的排放量（自从1990年以来上升了25%）的作用，并且，许多签字国并没有采取足够严格的政策来尽力完成他们所制定的2008—2012年度的目标。
比较实际的结论是，如果全球变暖是一个潜在的灾难，那么的解决办法就是新技术。只有积极进取的研究开发项目才可能会找到办法打破我们对于化石燃料的依赖，或者找到应对这一难题的办法。
全球变暖这场辩论所存在的问题是，它本是一个技术问题，却都已经变成了一个道德问题。这个被忽视的真相就是，如果不能解决这个技术问题，我们将对此束手无策。
