Bush Backs Spending for a 'Global Problem'

A group of distinguished American scientists last week confirmed that the world is warming and humans are probably to blame for most of the climate change. The analysis by a committee of the U.S. National Research Council (NRC) also confirmed that essentially identical conclusions from an international study had not been unduly distorted when summarized for public consumption. The NRC committee did play up the uncertainties in the international report, however--a point that President George W. Bush emphasized this week in calling for new research and technology initiatives to combat what is clearly a global problem.
