This story was updated Nov. 29 with the Senate committee's vote.

More than 300 scientists wrote to the Senate on Tuesday opposing Kathleen Hartnett White's nomination to the top White House environment post. They cited the importance of scientific integrity and wrote that they oppose her nomination "because one thing more dangerous than climate change is lying."

On Wednesday, the Senate Environment and Public Works Committee voted to move her nomination forward to a full Senate vote, along with the nomination of Andrew Wheeler, a coal lobbyist who President Donald Trump picked to be second in command at the Environmental Protection Agency.

If the Senate confirms White as head the Council on Environmental Quality, it would place a fossil fuels industry supporter and vocal denier of mainstream climate science at the center of federal interagency policy discussions on energy and environment.

White, a fellow of the conservative Texas Public Policy Foundation and former head of the Texas Commission on Environmental Quality, has written extensively against regulation of carbon dioxide, which she calls "the gas of life." She has also written in favor of increasing the use of fossil fuels and has criticized the Endangered Species Act.

"As scientists and scholars, we are alarmed by Ms. Hartnett White's actions and statements, particularly, her recent assertion that carbon dioxide is not a harmful pollutant," the scientists wrote in their letter to senators. "There is unanimous agreement across peer-reviewed climate science that carbon dioxide and other greenhouse gases released by human activities are contributing to the harmful effects of climate change. To state otherwise in the face of overwhelming evidence is simply unsupportable."

"This is not a partisan issue; it is a matter of defending scientific integrity," the letter says. "Climate change threatens us all, regardless of political affiliation. Confirming Kathleen Hartnett White at the helm of the Council on Environmental Quality would have serious consequences for people and the ecosystems of the only planet that can support us."

Amanda Lynch, a climate scientist at Brown University and head of the Institute at Brown for Environment and Society, drafted the letter and began collecting signatures from colleagues after hearing White's testimony at her Senate confirmation hearing in early November.

"The thing that tipped me over the edge was her appearance before the Senate where she just couldn't answer fundamental questions about environmental science that would affect her ability to do her job," Lynch said.

For example, White seemed to question whether warm water expands, which is basic physical science. When asked if the law of thermal expansion applies to sea water (starting at 9:39 in the video below), White replied: "Again, I do not have any kind of expertise or even much layman study of the ocean dynamics and the climate change issues."

Asked about her understanding of fossil fuels' impact on oceans, White said: "I have a very superficial understanding as far as that. Acidification issues are one. I have not read widely or deeply."

Asked about her previous statements that carbon dioxide is not dangerous, White said at the hearing: "CO2 in the atmosphere has none of the characteristics of a pollutant that contaminates and fouls and all of that that can have direct impact on human health. As an atmospheric gas, it is a plant nutrient."

The person who becomes head of the Council on Environmental Quality will have an impact on the discourse in the White House, Lynch noted.

"My hope is that there are some moderate Republicans that will take this into consideration when deciding whether to confirm her or not," Lynch said. "It's not a partisan issue. It's a matter of fact. We need to start to treat it as such."

"My sense is that President Trump does not necessarily disbelieve the scientists when they talk about climate change, based on what he has said in decades past," she said. "But it's become a political football."
