Researchers say DOE report cherry-picks data to downplay threat of greenhouse gases

The last assessment of the state of climate science from the United Nations’s Intergovernmental Panel on Climate Change (IPCC), published in its final form 2 years ago, was a monumental effort, with 721 volunteer scientists synthesizing all available published research. Yesterday, the Department of Energy (DOE) released its own climate assessment, as part of a campaign by the U.S. Environmental Protection Agency (EPA) to overturn its landmark endangerment finding from 2009, which found that burning fossil fuels endangers public health and established carbon dioxide as a pollutant EPA could regulate. But the DOE report—called A Critical Review of Impacts of Greenhouse Gas Emissions on the U.S. Climate—had fewer authors than IPCC’s: just five.

Handpicked by DOE Secretary Chris Wright, a fossil fuel entrepreneur, the authors are well known to climate scientists. Although the members of this Climate Working Group all hold scientific doctorates, they hold contrarian views on climate science that are out of step with the mainstream. The report, assembled in months, argues that some of the warming attributed to fossil fuel burning is instead driven by natural cycles or variability in the Sun, and that sea level rise has not been accelerating. Climate researchers say the authors cherry-picked evidence and highlighted uncertainties to achieve the net effect of downplaying the impacts of climate change. “This shows how far we have sunk,” says Naomi Oreskes, a historian of science at Harvard University. “Climate denial is now the official policy of the U.S. government.”
