"In the four years since President Bush took office, scientific sleuths trying to understand the extent of global climate change -- and finger the culprits -- have come up with several important new clues:
• Glaciers in the Antarctic and in Greenland are melting much faster than expected, and the fastest moving glacier in the world has doubled its speed.
• Worldwide, plants are blooming several days earlier than they did a decade ago, and animals are migrating toward cooler climates across the globe.
• The oceans have absorbed extra heat trapped in the atmosphere, which indicates Earth's temperature should rise by another degree Fahrenheit in the coming decades.
The president's scientific and policy advisers on global warming do not dispute these findings, but none of them has persuaded the White House to alter its current climate policy. Rather than endorsing mandatory limits on carbon dioxide emissions linked to warming, the course embraced by most of America's allies, the White House is focusing on technological fixes: developing energy sources that burn cleaner or finding ways to extract excess carbon dioxide out of the atmosphere. "Our approach is founded on sound science, and on trying to address, with different strategies, climate change," said Paula J. Dobriansky, undersecretary of state for global affairs.

"We're learning fast, but part of what we're learning is the climate system is really complicated. . . . I don't think we'll ever make the kind of prediction Bush would want," said Wallace S. Broecker, a geochemist at Columbia University's Lamont-Doherty Earth Observatory. Broecker believes the United States has to act quickly to counter its contribution to global warming. "If we don't pick up the pace, we're not going to get there." The United States is taking part in the Buenos Aires talks even though the administration opted out of the Kyoto Protocol, which will restrict carbon emissions in most industrialized nations starting in 2008. Dobriansky said U.S. officials will try to convince their counterparts that technological change, not government mandates, offers the best chance to preserve both economic growth and the environment."
