填空题
The science of climate change is easy. We burn
millions of tons of fossil fuels(矿物燃料) a year, sending millions of carbon
dioxide into the atmosphere. The gas acts like the windows of a greenhouse,
retaining heat that would otherwise radiate(散发)away. Result: The world is
warmer—half a degree or so in the past 100 years. Think it
doesn't matter? Your grandchildren will disagree. In the near term, this warning
contributes to accidental weather. More storms here; more drought (干旱) there.
Over time, the disastrous consequences may include melted ice caps and higher
sea levels. No more icebergs, No more Miami. With 4 96 of the
world population, the United States produces 22 % of all greenhouse gas.
Clearly, we bear some responsibility. Which is why, combined with the threat to
future Americans, the White House this week outlined a new plan to reduce
greenhouse gas emissions(排放). The plan is painfully modest. It
delays hard limits for 10 years, hoping that tax incentives(激励措施)and pollution
credits will spur(刺激)industries to act on their own. And the final
goal--reduction to 1990 levels by about 2010—is lower than much desire.
