...Scientists estimate that unless emissions of CO2 and similar compounds are controlled, global temperatures by the end of the next century will rise how many degrees Fahrenheit...
...Earth is warming--that's a fact. Burning fossil fuels raises atmospheric CO2-concentrations--that's a fact, too. But that anthropologically elevated CO2-levels contribute to global warming--that's a religious question. Or so it has long seemed...
...panel also warns that temperatures could rise even higher than previously predicted if emissions of so-called greenhouse gases such as CO2 were not curbed. Estimated temperature increases over the next 100 years are between three and 11 degrees Fahrenheit. This upper bound is up from 6.3 degrees estimated in the last report in 1995. In comparison, current temperatures are only nine degrees Fahrenheit warmer than at the end of the last Ice Age thousands of years ago, but it is not necessary to look at the worst-case scenario. Even the lower bound of three degrees Fahrenheit would...
...Meteorology at MIT. Often described as a champion to political conservatives and industrial interests, he has become famous for statements such as "we don't have any evidence that [global warming] is a serious problem." On the basis of his own climate model, Lindzen has so far argued that CO2 does not contribute to global warming. Now, however, he helped write one chapter of the 1000-page assessment, and was recently quoted as saying that "there has to be a human component to the change that's under...
...Bush, on the other hand, do not want to sign the treaty since it excludes many developing countries, including India and China.

The ultimate goal must be to include all developed and developing countries in a joint effort to curb the world's greenhouse gas emissions, but this cannot happen without U.S. leadership...
