John Kerry was hit with an ethics complaint Tuesday alleging he "disregarded" scientific evidence on climate issues.

Protect the Public's Trust filed the complaint against the Biden administration's special presidential envoy for climate, detailing a May 10 speech in which Kerry claimed 15 million people perish every year due to greenhouse gas emissions.

"This claim is both tremendously consequential and entirely unsupported by scientific evidence," the letter to State Department and White House Office of Science and Technology Policy officials states.

PPT is calling for an investigation into Kerry's comments for violating the Biden administration's scientific integrity policies and are asking the government to "adequately correct the public record and deter similar hysterical claims in the future."

“[Fifteen] million people are dying every single year around this planet as a consequence of greenhouse gas emissions in the atmosphere, in the air which travels around and drops in the form of pollution and is warming the ocean at record rates, changing the chemistry of the ocean itself," Kerry, a former secretary of state, said at the U.S. Department of Agriculture's AIM for Climate Summit. "Without action, millions of lives and the livelihood of the planet is at risk."

In addition to Kerry's 15 million air deaths, he also said another 10 million people die annually from extreme heat.

“There are few more perilous breaches of scientific integrity than for public officials to convey inaccurate data to the public knowingly or recklessly, especially when it is done to justify politically motivated decisions or agendas," PPT Director Michael Chamberlain told the Washington Examiner. "Simply put, hysteria, hyperbole, and misrepresentation of data have no place in our government’s official pronouncements."

PPT's letter countered Kerry's claims with data with some of the most far-reaching death toll predictions in scientific literature, which claim the globe could see 3.4 million deaths per year by 2100, which is both significantly less than Kerry's prediction and also 77 years from now. Many of the deaths are attributed to wildfires and mosquito-borne illnesses.

"Despite the enormity of Mr. Kerry’s claim, he did not cite any scientific evidence for its basis," the letter states. "Nor is there any apparent scientific research that supports a claim that there are currently 15 million people dying yearly due to greenhouse gas emissions – or any other single cause of death that is tracked."

According to PPT, Kerry violated several of the Biden administration's scientific integrity policies, including a February 2021 memorandum called "Restoring Trust in Government Through Scientific Integrity and Evidence-Based Policymaking," OSTP's "Framework for Federal Scientific Integrity Policy and Practice," and the State Department's scientific integrity policy.

"The American public’s trust in its government has plunged to depths never before seen and is unlikely ever to recover if we have powerful officials throwing out numbers unsupported by evidence," Chamberlain said.

Neither OSTP nor the State Department returned a request for comment from the Washington Examiner.
