National Academies Publish New Report Reviewing Evidence for Greenhouse Gas Emissions and U.S. Climate, Health, and Welfare

The report focuses on evidence gathered by the scientific community since 2009, when the U.S. Environmental Protection Agency found that greenhouse gas emissions threaten public health and welfare. The EPA recently gave notice of proposed rulemaking indicating its intention to rescind this finding.

The report says EPA's 2009 finding was accurate, has stood the test of time, and is now reinforced by even stronger evidence. Much of the understanding of climate change that was uncertain or tentative in 2009 has now been resolved by scientific research, the report says.

"This study was undertaken with the ultimate aim of informing the EPA, following its call for public comments, as it considers the status of the endangerment finding," said Shirley Tilghman, professor of molecular biology and public affairs, emeritus, and former president, Princeton University, and chair of the committee that wrote the report. "We are hopeful that the evidence summarized here shows the strong base of scientific evidence available to inform sound decision-making."

To prepare its report, the committee considered widely available datasets that provide information about greenhouse gas emissions, the climate system, and human health and public welfare; a broad range of peer-reviewed literature and scientific assessments; and more than 200 comments submitted in response to a request for information.

The report concludes:
