      Panelist Who Dissents on Climate Change Quits
      August 23, 2005

      A scientist who has long disagreed with the dominant view that global
      warming stems mainly from human activity has resigned from a panel
      that is completing a report for the Bush administration on
      temperature trends in the atmosphere.

      The scientist, Roger A. Pielke Sr., a climatologist at Colorado State
      University, said most of the other scientists working on the report
      were too deeply wedded to particular views and were discounting
      minority opinions on the quality of climate records and possible
      causes of warming.

      "When you appoint people to a committee who are experts in an area
      but evaluating their own work," he said in an interview, "it's very
      difficult for them to think outside the box of their research."

      Administration officials said the resignation would not affect the
      quality or credibility of the report, a draft of which is being
      finished in the next few weeks.

      The report, the first product of President Bush's 10-year climate
      change research program, is likely to be closely scrutinized by
      climate scientists and environmental and industry groups for any sign
      of bias or distortion.
      Its main focus is to explore why thermometers at the earth's surface,
      especially in the tropics, have measured more warming than has been
      detected by satellites and weather balloons in the troposphere, the
      layer of the atmosphere up to where jetliners cruise.

      Dr. Pielke contends that changes in landscapes like the spread of
      agriculture and cities could explain many of the surface climate
      trends, while most climate experts now see a clear link to
      accumulating emissions of heat-trapping gases like carbon dioxide.

      James R. Mahoney, an assistant secretary of commerce and the director
      of the federal climate research program, said the scientists involved
      in generating the report were "representative of the broad views" on
      the questions.

      Mr. Mahoney noted that drafts of the climate report would be reviewed
      by the National Academy of Sciences and were subject to public

      "I'm disappointed that Dr. Pielke has chosen to resign over this,"
      Mr. Mahoney said.

      Dr. Pielke said he decided to resign after three papers on the
      troposphere trends were published online on Aug. 11 by the journal
      Science. The papers said errors in satellite and balloon studies in
      the tropics explained why earlier analyses failed to find warming in
      the troposphere.

      Several authors of those papers, who are also authors of the coming
      government report, said at the time that the new findings would be
      discussed in the report.

      Dr. Pielke said those statements were an effort to influence the
      shape of the final report.

      Several authors of those papers denied this, saying the process of
      creating the reports is intended to be public, while the contents
      remain confidential for now.

      John R. Christy, another author of the coming report who like Dr.
      Pielke doubts that human-caused warming poses a serious threat, said
      that while disagreements were normal, the effort to generate the
      report was improving understanding.

      "This process is the worst way to generate scientific information,"
      said Dr. Christy, who teaches at the University of Alabama,
      Huntsville. "Except for all the others."
