Ms. Bumiller: Mr. President, why did your administration change its position on what causes global warming?
THE PRESIDENT: I don't think we did.
Ms. Bumiller: According to --
THE PRESIDENT: I don't think so, Elisabeth.
Ms. Bumiller: You said that it's almost certainly carbon monoxide which you hadn't said in the past, carbon dioxide.
THE PRESIDENT: I think that was my position during the campaign, if I'm not mistaken.
Ms. Bumiller: It changed --
MR. McCLELLAN: You're talking about the National Academy of Science report?
Ms. Bumiller: Yes, yes.
MR. McCLELLAN: We've always talked about how that would - we'd be guided by their science on the issue, and that's why the President has done a lot in terms of climate change, advancing the science of climate change, and also doing more research --
THE PRESIDENT: Let me get back with you on that, because I think you might -- I don't know why you said what you just said.
Ms. Bumiller: Well, we had a story in the paper this morning saying that you issued a report saying --
THE PRESIDENT: Oh, okay, well, that's got to be true.
WASHINGTON (Reuters) -- Warmer temperatures in North America since 1950 were probably caused in part by human activity, the Bush administration said in a report that appeared to contradict the White House position there was no clear scientific proof on the causes of global warming.
In a report sent to Congress this week, the administration noted a recent government-sponsored study supported the view of many scientists that human action from driving automobiles to running power plants helped cause global warming.
"North American temperature changes from 1950 to 1999 were unlikely to be due only to natural climate variations," the report said.
Warmer temperatures that occurred from 1900 to 1949 were "likely due" to natural causes, the report added.
The brief passage in the report was surprising because President Bush and other senior administration officials have long insisted there was no clear scientific proof to link human activities to global warming.
In an interview with the New York Times, published on its Web site, Bush was asked why his administration had changed its position. "Ah, did we?" Bush replied. "I don't think so."
White House spokesman Trent Duffy said the study did not change the administration's position and more research was needed. "The president's policy is the same ... we need to fill in the knowledge and the scientific gaps," he said.
Bush withdrew the United States from participating in the Kyoto treaty that sought to reduce global warming emissions produced mostly by industrialized nations. He said the accord's tough requirements would be too costly to the U.S. economy.
The White House has promoted a voluntary program for U.S. power plant and oil refinery owners and other industries to cut their so-called greenhouse gas emissions.
The specific study on temperature changes from 1950 to 1999 was included in a list of research projects on climate change sponsored by various government agencies that were recently completed or are under way.
In its report to Congress on the research, the administration said the studies did not "make any findings of fact that could serve as predicates for regulatory action."
One environmental group said, however, the report put pressure on Bush to address the global warming issue when the president lays out his plans for a second term at the Republican convention next week in New York.
"It will be interesting to see whether he plans to do something about global warming or just continue ignoring it for political reasons," said Philip Clapp, president of the National Environmental Trust.
