Only in the US could a politician get away with saying something like this…

“We are short of carbon dioxide for the needs of the plants,” Anderson, a retired science teacher, told the committee overseeing environmental programs in the the state on Tuesday. “Concentrations reached 600 parts per million at the time of the dinosaurs and they did quite well. I think we could double the carbon dioxide and not have any adverse effects.”

Such claims are at odds with credible climate science, according to Joe Andrade, a retired University of Utah engineering professor. Carbon levels at 500 ppm would warm the planet and acidify the oceans to a devastating degree, he said.

Yes the planet will be just fine with more carbon dioxide in the air and life will go on but it’ll be life that’s much different than what we are use to. It’s virtually a consensus among scientists (and countries outside the US) that man made global warming through CO2 and other green house gasses is a problem.
