The reasoning behind saying that pollen counts are higher and linking that to CO2 without doing some investigation is spin and presenting that as "fact" is "brainer no-using".

Logic and reasoning often have nothing to do with what is really happening, which is why theories are boundless and anything can be "proven" with rhetoric.

Cars today are putting out less pollution than they did thirty years ago. CO2 levels have been measured as being higher than they were thirty years ago, therefore more CO2 causes cars to pollute less.
