Climate scientist Dr. Murry Salby, Professor and Climate Chair at Macquarie University, Australia explains in a recent, highly-recommended lecture presented at Helmut Schmidt University, Hamburg, Germany, why man-made CO2 is not the driver of atmospheric CO2 or climate change. Dr. Salby demonstrates:

CO2 lags temperature on both short [~1-2 year] and long [~1000 year] time scales
The IPCC claim that “All of the increases [in CO2 concentrations since pre-industrial times] are caused by human activity” is impossible
“Man-made emissions of CO2 are clearly not the source of atmospheric CO2 levels”

Satellite observations show the highest levels of CO2 are present over non-industrialized regions, e.g. the Amazon, not over industrialized regions
96% of CO2 emissions are from natural sources, only 4% is man-made
Net global emissions from all sources correlate almost perfectly with short-term temperature changes [R2=.93] rather than man-made emissions
Methane levels are also controlled by temperature, not man-made emissions
Climate model predictions track only a single independent variable – CO2 – and disregard all the other, much more important independent variables including clouds and water vapor.
The 1% of the global energy budget controlled by CO2 cannot wag the other 99%
Climate models have been falsified by observations over the past 15+ years
Climate models have no predictive value
