Sen. Tom Carper recently wrote to Environmental Protection Agency Acting Administrator Andrew Wheeler to express grave concerns regarding his recent public comments with respect to the Trump administration’s release of the Fourth National Climate Assessment.

The nearly 1,700-page scientific report, congressionally-mandated and issued the day after Thanksgiving by 13 federal agencies and more than 300 federal experts, highlights the impacts climate change has on human health, the economy and the environment. The report also highlights some of the vulnerabilities in communities across the country such as deteriorating infrastructure, stressed ecosystems and economic inequality that will leave certain areas more susceptible to the most damaging effects of climate change.

The letter notes that since the report was released, comments made by President Donald Trump, White House Press Secretary Sarah Huckabee Sanders and Wheeler sought to undermine its findings. In the letter, Carper also demanded documents that detail EPA’s views and involvement in shaping the Trump administration’s response to its own report.

“If the U.S. continues to ignore the dangers of climate change, the costs for all Americans will be devastating,” wrote Carper. “This isn’t an alarmist prediction. It doesn’t come from some left-leaning organization, and it doesn’t come from talk radio. It comes directly from our nation’s leading scientists. We may not all agree about what to do to address these dire warnings, but it disturbs me greatly that counter to the commitment you made to me during your confirmation hearing, you seem to be actively working to undermine and distort the scientific evidence itself.”
