Fmr EPA Scientist: CO2 not a pollutant & not causing warming

Fred H. Haynie, a retired EPA research scientist, has devoted the past four years to a study of global climate change, and in particular the relationship to CO2, as illustrated in his ppt presentation:

The findings include 1) anthropogenic CO2 emissions have not caused the rise in background levels of CO2, which is primarily due to rising temperatures in the arctic ocean sink, and 2) a greenhouse effect of CO2 is not causing global warming. Thus, controlling CO2 emissions will have no effect on natural climate change, CO2 cannot be considered a pollutant, and attempts to control CO2 emissions will only result in lower efficiency and waste of energy.
