Do CFCs cause climate change?

Another example of the science  not being “settled”.   Qing-Bin Lu, a professor of physics and astronomy, biology and chemistry at the University of Waterloo has found a strong correlation between the levels of CFC’s  (chlorofluorocarbon) and the levels of warming in earths atmosphere. The problem to be explained is why the climate has been cooling or at least steady temperature-wise since 2002. The atmospheric models produced by the IPCC show a strong feedback effect between the levels of CO2 and atmospheric temperatures, the problem is the real world observations show that is not what is happening.

Qing-Bin Lu says “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,”

His graph certainly looks interesting:
