er, this line is neither common nor sense - photosynthesis and plant life is a little more complex than that - in the first place, plants do reverse the process, using oxy and producing co2; in the 2nd place just because necessary does not mean that more of it is better (ie glass of water vs 2 gallons of water - if you drink enough water you will die). The problem with excess co2 (without going into the quantum mechanics of the interactions between molecules and radiation) is that co2 (along with water vapor and ozone) absorbs infra-red (heat) energy that normally would radiate out into space. Oops, back step - we receive energy from the sun in the form of radiation, which is absorbed and re-radiated back out into space in a balance. The less energy re-radiated back out into space, the warmer the system becomes.

Change is part of society and economics. If people can't adopt to change then they'll be left in the dust. But just because some national leader (Al Gore) spouts drabble long enough and the media takes the bait doesn't mean that we need to follow as well. As rational people, we need to examine with reason what is being shoveled to us and ask if it makes sense. With all the inconsistencies I've heard about global warming and the money trail I talked about above, global warming just doesn't pass my smell test.

Al Gore did not spout drabble - his movie contained some minor errors but then Al Gore is not a scientist - he is a concerned citizen reporting a problem. Show us some the your 'examine with reason' and tell us what does not make sense. What are the particular inconsistancies you have heard about global warming? What is the science that you have looked at? What is the money trail you are talking about? The money trail from the global warming deniers is far more interesting - what few scientists that are on that side of the discussion are usually in the pay of the petroleum, mining, interests -- doesn't that fail your sniff test?
I could go on but will wait to see if you are interested in discussing this in more detail.
