Jan Veizer

From Wikipedia, the free encyclopedia

Ján Veizer, born in Slovakia, 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 an award-winning isotope geochemist; his research intersts have included the use of chemical and isotopic techniques in determining Earth's climatic and environmental history ^[1].

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,which carried a 1.55 million euro value, awarded 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.

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 is supported by few other scientists.
