Hi,
Hopefully this will be the start of some more rational viewing of the subject, as I have said before CO2 plays a minute role in the grand plan.
You would have to get to levels of more than 5-6% (currently 0.04%) before any significant impact would be seen, and I have doubts that it could get there, as the ecosystem appears to be highly optimized to the removal of CO2 from the atmosphere.
Also the dataset that has been presented to the general public has been highly manipulated to prove the global warming case, i.e. the medieval warming period as well as the cooling period in the 70's didn't happen as far as they were concerned and were removed from the dataset.
The cooling process of the earth is driven by convection, a process that we are all familar with, and not infra red radiation (black body)which they want us to believe to make their models work.
Whereas particular matter pollution is a problem as it DOES effect rainfall by overloading the cloud formation process.
