[grrr]

let me start by saying i am not totally convinced about global warming being man made, some of the reasons are (maybe some of the scientific community can answer these)
1. carbon dioxide is supposed to be a greenhouse gas, but with my little understanding of chemistry it is heavier than air. so given the figures that have been produced about the billions of tons we are emmitting into the atmosphere we should be wading around in a co2 soup, however the co2 content in air is still around 4% which has not altered in the last 20 years.
2. current emmisions for uk cars is to be under 135g of carbon per km. if this is the case we are somehow producing more in emissions than we are actually feeding in in feul and air? if this is true we are well on the way to inventing perpetual motion.
Please do not take these as cynical remarks, but somehow the math does not add up. for global warming and climate change to be believable, the information being given has to be plausable.

I welcome your response Graham
