The Ottawa Citizen manages a very nice discussion of the theories of a distinguished Canadian scientist about Global Warming.
It is not hysterical and it presents the information in a mostly balanced way. Kudos.
A prominent University of Ottawa science professor says what we know about global warming is wrong -- that stars, not greenhouse gases, are changing Earth's climate.And he was able to do the research because of that $2.2 million grant from Germany. ;)
Jan Veizer says high-energy rays from distant parts of space are smashing into our atmosphere in ways that make our planet go through warm and cool cycles.
...he has published his theory in Geoscience Canada, the journal of the Geological Association of Canada. The article is called "Celestial Climate Driver: A Perspective from Four Billion Years of the Carbon Cycle."
In his paper, Mr. Veizer concludes: "Empirical observations on all time scales point to celestial phenomena as the principal driver of climate, with greenhouse gases acting only as potential amplifiers."
...The Royal Society of Canada called him "one of the most creative, innovative and productive geoscientists of our times," and added: "He has generated entirely new concepts that have proven key in our understanding the geochemical history of Earth."
He was the director of the Earth System Evolution Program of the Canadian Institute of Advanced Research. He held a special research chair at the University of Ottawa.
He won the 1992 Gottfried Wilhelm Leibniz Prize, worth $2.2 million, and representing the German government's highest prize for research in any field. The judges said he "has in front of his eyes the overall picture of the Earth during its entire 4.5 billion years of evolution," and he is "one of the most creative ... geologists of his time."
...Mr. Veizer felt uncomfortable with the idea that high levels of carbon dioxide alone are causing hot spells. For one thing, he says, Earth would have needed vastly more carbon dioxide than today to change temperatures so much. For another, his reading of the graphs shows that some rises in carbon dioxide came after increases in temperature, not before. And in one case at least, we appear to have had very high carbon dioxide at a cold time -- an "icehouse," not greenhouse.
He wondered: What if something else makes the temperature go up and down?
The $2.2-million German prize ended up financing his research. The professor says he would never have found financial support any other way; the prize gave him "absolute freedom."
