Matthew Wielicki, a climate scientist and lead author of a major federal climate report, has been blocked by the Trump administration from releasing the final version of the document, which he says was suppressed due to its conclusions on climate change. Wielicki claims the White House pressured the National Oceanic and Atmospheric Administration (NOAA) to delay or alter the report, which details the impacts of rising global temperatures on the United States.
Background of the Report
The report, titled "Climate Science Special Report," is part of the National Climate Assessment, a quadrennial review mandated by Congress. It synthesizes thousands of peer-reviewed studies to project future climate impacts. Wielicki, a professor at the University of Alabama in Huntsville, has led the effort since 2015. The report's key findings include that human activities are the dominant cause of warming since the mid-20th century, and that extreme weather events are becoming more frequent and severe.
White House Interference Allegations
Wielicki told the Guardian that the White House Office of Science and Technology Policy (OSTP) requested changes to the report's executive summary, including the removal of references to human-caused climate change. When he refused, the White House blocked the report's release. "They wanted to water down the language to make it seem less certain," Wielicki said. "I refused to change the science." The White House has denied any interference, but Wielicki maintains that the report is being held up for political reasons.
Impact on Climate Policy
The suppression of the report could have significant implications for U.S. climate policy. Without the official assessment, federal agencies and local governments may lack the scientific basis for adaptation and mitigation strategies. Environmental groups have condemned the move, calling it an attack on science. "This is a clear attempt to hide the truth about climate change from the American people," said a spokesperson for the Union of Concerned Scientists.
Legal and Scientific Reactions
Several Democratic lawmakers have called for an investigation into the White House's actions. Senator Brian Schatz (D-Hawaii) said the administration is "putting politics ahead of science." Meanwhile, the American Geophysical Union issued a statement expressing "deep concern" over the suppression of the report. Wielicki has not ruled out legal action to force its release. "The report is complete and ready for publication," he said. "It's time to let the science speak."
