Global warming? A Canadian scientist gives us good reason to question the "CO2 causes global warming" mantra. My favourite line is the quote from Groucho Marx: "Who are you going to believe, me or your own lying eyes?"
A peer-reviewed study by a respected Canadian physicist blames the interplay of cosmic rays and chlorofluorocarbons for 20th-century warming. The CFCs are now gone, and so is warming — perhaps for the next 50 years.
Qing Bin-Lu, a professor of physics and astronomy at Canada's University of Waterloo, is a believer in the value of drawing conclusions from observable data and not from selective data fed into computer models that are based on false assumptions and include "fudge factors."
In a peer-reviewed paper published in the prestigious online journal Physics Reports, Lu, who holds a Ph.D. in physics from the University of Newcastle, reports that CFCs, the compounds once widely used as refrigerants, and cosmic rays, which are energy particles originating in outer space, are mostly to blame for climate change, rather than carbon dioxide (CO2) emissions.
