Jan Veizer

Ján Veizer is an emeritus professor of Earth Sciences at the University of Ottawa and holder of the NSERC/Noranda/CIFAR Industrial Chair in Earth System Isotope and Environmental Geochemistry. He is one of the world leaders in isotope geochemistry^{[citation needed]} and its use in determining Earth's climatic and environmental history^{[citation needed]}.

Dr. Veizer has received the 1987 W.W. Hutchison Medal for young individuals making exceptional advances in Canadian earth science research, the 1991 Willet G. Miller Medal for outstanding contributions in geology, the 1992 Gottfried Wilhelm Leibniz Prize for understanding of the geochemistry of sediments, the 1995 Logan Medal which is the Geological Association of Canada's highest honour[1], the 2000 Bancroft Award for contributions furthering the public understanding of the Earth sciences.

The Gottfried Wilhelm Leibniz Prize, which carries a 1.55 million euro value, allowed him to embark on an ambitious research program that greatly expanded science's knowledge of isotopic changes through time^{[citation needed]}.

He has researched global warming but attributes more of the warming to non-human influences. [2] However this research has been criticized [3] and the cosmic ray theory put forward by Veizer supported by few other scientists.
