Dr. Tim Ball, one of the first Canadians to hold a Ph.D. in climatology, wrote his doctoral thesis at the University of London (England) using the remarkable records of the Hudson’s Bay Company to reconstruct climate change from 1714 to 1952. He has published numerous articles on climate change and its impact on the human condition. Dr Ball has served on numerous committees at the federal, provincial, and municipal levels on climate, water resources, and environmental issues. He was a professor of climatology at the University of Winnipeg for 28 years. He is currently working as an environmental consultant and public speaker based in Victoria and has written, with Dr Stuart Houston, 18th Century Naturalists on Hudson Bay, a book on the science and climate of the fur trade (McGill-Queens University Press, 2003).
So you would expect Dr. Ball to be right on board with global warming, right? wrong.
"The Science Isn't Settled - The Limitations of Global Climate Models," Dr. Timothy Ball, March 21, 2007
Computerized models of the earth’s climate are at the heart of the debate over how public policy should respond to climate change. Global climate models – also called general circulation models – attempt to predict future climatic conditions starting with a set of assumptions about how the climate works and guesses about what a future world might look like in terms of population, energy use, technological development, and so on.
Analysts have pointed out, however, that many of the assumptions used in modeling the climate are of dubious merit, with biases that tend to project catastrophic warming, and have argued that climate models have many limitations that make them unsuitable as the basis for developing public policy.
Dr. Tim Ball discussed the paper The Science isn't Settled, published by the Fraser Institute (www.fraserinstitute.ca/admin/books/files/ScienceIsntSettled.pdf), and examined two major limitations that hinder the usefulness of climate models to those forming public policy.
