Hill Heat

The leading contender for the Republican nomination to compete for Sen. Tom Harkin’s (D-Iowa) seat doubts the science of climate change and rejects any response that calls for more than voluntary actions. In a May 9, 2014 interview with the Des Moines Register editorial board, Iowa state senator Joni Ernst, a candidate for the U.S. Senate, expressed her disbelief in the science of anthropogenic climate change.

Yes, we do see climates change but I have not seen proven proof that it is entirely man-made. I think we do have cyclic changes in weather, and I think that’s been throughout the course of history. What impact is man-made. . . but I do think we can educate people to make good choices.

In reality, the carbon-dioxide greenhouse effect is a physical fact known since the 1800s. The only scientifically plausible systematic explanation for the rapid and continuing warming of the planetary climate since 1950 is industrial greenhouse pollution.

When asked how she believes the nation should respond to “our current climate situation,” her first recommendation was “encouraging people to, obviously, recycle.” She repeatedly and adamantly opposed “cap and trade” as a “tax on energy” and a “mandate.” She then argued the renewable fuel standard, which mandates the use of ethanol in gasoline, was not a mandate.

During the interview, Ernst expressed the similarly contrarian and evidence-less belief that Iraq had weapons of mass destruction before the United States invaded in 2003.

Ernst has been endorsed for the June 3 Republican primary by the Register, Sarah Palin, the National Rifle Association, and the U.S. Chamber of Commerce. If she wins, she will face Rep. Bruce Braley in the general election.
