A Canadian climate scientist has broken ranks with many of his colleagues and says that carbon dioxide is not the cause of climate change. He blames instead chlorofluorocarbons, known as CFCs.
The scientist is Qing-Bin Lu, a professor of physics and astronomy, biology and chemistry in Waterloo University’s Faculty of Science in Ontario Province.
A release from the university said that the professor’s peer-reviewed study had been published in the International Journal of Modern Physics B this week.
Much of the scientific establishment blames what they call global warming on an increase of carbon dioxide in the atmosphere, and they usually blame human activities for raising the level.
In a release from the university Lu said that since 2002, global temperatures have actually declined and the decline correlates with a reduction in chlorofluorocarbons over the same period. The university said the findings are based on in-depth statistical analyses of observed data from 1850 up to the present time, Lu’s cosmic-ray-driven electron-reaction theory of ozone depletion and his previous research into Antarctic ozone depletion and global surface temperatures.
In Costa Rica there is a major effort to make the country carbon neutral by 2021, although the term has not been fully defined. The central government also has received international funds to begin developing a carbon credit system. There also is substantial private investment in firms that will measure the carbon footprint of businesses, for now on a voluntary basis.
Former U.S. vice president Al Gore has become the leading advocate against human-caused changes in the carbon dioxide level, mainly through his movie “An Inconvenient Truth.” He also is involved in carbon trading schemes.
Costa Rican President Laura Chinchilla has gone on record demanding that First World countries compensate developing lands because the carbon they produce results in warmer weather and stronger storms.
“Conventional thinking says that the emission of human-made non-CFC gases such as carbon dioxide has mainly contributed to global warming. But we have observed data going back to the Industrial Revolution that convincingly shows that conventional understanding is wrong,” said Lu in a university release. “In fact, the data shows that CFCs conspiring with cosmic rays caused both the polar ozone hole and global warming.”
“My calculations of CFC greenhouse effect show that there was global warming by about 0.6 °C from 1950 to 2002, but the earth has actually cooled since 2002. The cooling trend is set to continue for the next 50-70 years as the amount of CFCs in the atmosphere continues to decline,” he said.
Chlorofluorocarbons concentrations in the atmosphere have been in decline because of the Montreal Protocol on Substances that Deplete the Ozone Layer adopted in 1987. They have been used in the manufacture of aerosol sprays, blowing agents for foams and packing materials, as solvents, and as refrigerants, according to the U.S. National Oceanic and Atmospheric Administration.
Lu says that cosmic rays, not ultraviolet light, break down chlorofluorocarbons, the ozone-depleting molecules, and then ozone. The chlorofluorocarbons are blamed for the so-called Antarctic ozone hole.
“This study underlines the importance of understanding the basic science underlying ozone depletion and global climate change,” said Terry McMahon, dean of the faculty of science. “This research is of particular importance not only to the research community, but to policy makers and the public alike as we look to the future of our climate.” He was quoted in the same release.
The university release is HERE! The bombshell study is certain to generate strong reactions because so many researchers have academic investments in the carbon dioxide theory.
