Long-term global cooling began in 2002, according to a just-released study in the Journal of Cosmology, a peer-reviewed publication produced at Harvard-Smithsonian’s Center for Astrophysics. Man-made global warming was real and dangerous, the study finds, but the danger has passed.

The study, authored by Qing-Bin Lu, a rising star at the Department of Physics and Astronomy at the University of Waterloo in Canada, explains why climate models have been so spectacularly wrong in trying to tie the global warming of the last half of the 20th century to CO2 — the climate modelers fingered the wrong culprit when they targeted CO2. The true culprits, Dr. Lu explains, were CFCs, the now banned substances that until the 1990s had been a refrigerant and propellant to products as diverse as air conditioners and hair spray cans.
