Report by the E.P.A. Leaves Out Data on Climate Change

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.

The report, commissioned in 2001 by the agency's administrator, Christie Whitman, was intended to provide the first comprehensive review of what is known about various environmental problems, where gaps in understanding exist and how to fill them.

The editing eliminated references to many studies concluding that warming is at least partly caused by rising concentrations of smokestack and tail-pipe emissions and could threaten health and ecosystems.

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.
