“I, and many other scientists, think the warming will be small compared the natural fluctuations in the earth’s temperature, and that the warming and increased CO2 will be good for mankind.”

“We know that carbon dioxide has been a much larger fraction of the earth's atmosphere than it is today, and the geological record shows that life flourished on land and in the oceans during those times. The incredible list of supposed horrors that increasing carbon dioxide will bring the world is pure belief disguised as science.”

“Shut up...The demonisation of carbon dioxide is just like the demonisation of the poor Jews under Hitler. Carbon dioxide is actually a benefit to the world, and so were the Jews.”

“I like to call this the CO2 anti-defamation league, because, there is the CO2 molecule, and it has undergone decade after decade of abuse, for no reason. We’re doing our best to try and counter this myth that CO2 is a dangerous pollutant. It’s not a pollutant at all. ... We should be telling the scientific truth, that more CO2 is actually a benefit to the earth.”

“There’s a whole area of climate so-called science that is really more like a cult. It’s like Hare Krishna or something like that. They’re glassy-eyed and they chant. It will potentially harm the image of all science.”

“I am trying to explain to my fellow Americans the serious damage that will be done to us, and indeed to the whole world, by cockamamie policies to ‘save the planet’ from CO2.”

“Temperatures have not risen very much, and most of the temperature rise is probably completely natural, and has nothing to do with increasing CO2. Industrialization probably played a small role, but I think it's very hard to tell how much.”
