Washington By 2020, the United States will emit almost one-fifth more gases that lead to global warming than it did in 2000, increasing the risks of drought and scarce water supplies.
That projection comes from an internal draft report from the Bush administration that is more than a year overdue at the United Nations. The Associated Press obtained a copy Saturday.
The United States already is responsible for roughly one-quarter of the world's carbon dioxide and other "greenhouse" gases that scientists blame for global warming.
The draft report, which is still being completed, projects that the current administration's climate policy would result in the emission of 9.2 billion tons of greenhouse gases in 2020, a 19 percent increase from 7.7 billion tons in 2000.
