William Happer, PhD Biography

Professor of Physics at Princeton University
Con to the question "Is Human Activity Primarily Responsible for Global Climate Change?"

“The cessation of observed global warming for the past decade or so has shown how exaggerated NASA’s and most other computer predictions of human-caused warming have been—and how little correlation warming has with concentrations of atmospheric carbon dioxide. As many scientists have pointed out, variations in global temperature correlate much better with solar activity and with complicated cycles of the oceans and atmosphere. There isn’t the slightest evidence that more carbon dioxide has caused more extreme weather…
The current levels of carbon dioxide in the earth’s atmosphere, approaching 400 parts per million, are low by the standards of geological and plant evolutionary history. Levels were 3,000 ppm, or more, until the Paleogene period (beginning about 65 million years ago). For most plants, and for the animals and humans that use them, more carbon dioxide, far from being a ‘pollutant’ in need of reduction, would be a benefit…

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.”
