Update: Journal has no plans to retract NOAA study despite data manipulation concerns


The chief executive of a prominent science group said they currently have no intention of retracting a study at the center of a controversy involving accusations of scientific malpractice by National Oceanic and Atmospheric Administration (NOAA) scientists.

Rush Holt, president of the American Association for the Advancement of Science (AAAS), told lawmakers Tuesday he saw no reason to retract a 2015 NOAA study claiming to have eliminated the global warming “pause” from the temperature record.

Dr. John Bates, the former principal scientist at the National Climatic Data Center in Asheville, N.C., went public with complaints that NOAA scientists put a ‘thumb on the scale’ to get results that showed more global warming since 1998.

Holt said he sees nothing wrong with the study, and that Bates’ accusations amounted to an “internal” NOAA dispute over archiving practices. NOAA’s 2015 study was published in the journal Science, which is published by AAAS.

“This is not the making of a big scandal,” said Holt, a former Democratic congressman. “This is the internal dispute between two factions of an agency.”

“There’s nothing to suggest there are problems with that work,” Holt said.

Texas Republican Rep. Lamar Smith disagreed.

“It may be a lot more serious than you think,” said Smith, who chairs the House Committee on Science, Space and Technology.

Smith launched an investigation into Karl’s 2015 study, eventually hearing from other NOAA employees the study may have been rushed to influence policymakers meeting at a United Nations summit later that year.

Smith subpoenaed NOAA for emails related to the study, but the agency fought back. NOAA eventually handed over emails, but many were redacted. Smith has used Bates’ public complaints as a launch pad for further inquiry.
