The Environmental Protection Agency is preparing to publish a draft report next week on the state of the environment, but after editing by the White House, a long section describing risks from rising global temperatures has been whittled to a few noncommittal paragraphs.

Among the deletions were conclusions about the likely human contribution to warming from a 2001 report on climate by the National Research Council that the White House had commissioned and that President Bush had endorsed in speeches that year. White House officials also deleted a reference to a 1999 study showing that global temperatures had risen sharply in the previous decade compared with the last 1,000 years. In its place, administration officials added a reference to a new study, partly financed by the American Petroleum Institute, questioning that conclusion.

In the end, E.P.A. staff members, after discussions with administration officials, said they decided to delete the entire discussion to avoid criticism that they were selectively filtering science to suit policy.

Administration officials defended the report and said there was nothing untoward about the process that produced it. Mrs. Whitman said that she was "perfectly comfortable" with the edited version and that the differences over climate change should not hold up the broader assessment of the nation's air, land and water.
