摘要

When coal, oil, and natural gas are burned to generate electricity, drive automobiles, run factories, and heat homes, the atmosphere is polluted with carbon dioxide, a gas that traps heat like the glass panes of a greenhouse. Scientists have been observing the buildup of carbon dioxide and other so-called greenhouse gases in the atmosphere for decades with increasing interest and concern. Yet, the problem of human-induced global climate change, or global warming, didn't emerge onto the public agenda until 1988, when a string of unusually hot weather, coupled with the Congressional testimony of NASA scientist Jim Hansen proclaiming a "high degree of confidence" that humans already were changing the Earth's climate, garnered headlines around the country.
