Amused - your lack of understanding the basic science here, and your ability to cling to faulty and dis-proven arguments - keep it coming, it's good entertainment.
You know - stuff like 'it's plant food', and my favorite today - 'the bit of CO2 that man is responsible for' - 29 billion tons - per year - is a 'bit'? Really?
Guess how many forests man has eliminated in the past 400 years? How about more than half of them? We wipe out 16 million hectares ( or just a bit - as you might say) - here's a stretch - fewer forests - less CO2 absorbed by plants?
You just don't get it - you think there is this big scam going on, and you and your right-wing cronies aren't going to fall for it - and you grasp at every little thing that has even the slightest hint of impropriety - and cling to it, even when it's discarded.
I can only guess how you would have been during the 'smoking is bad for your health' discussions, or the 'HIV causes AIDS' issues.
It's a fact that the earth has drastically (yes, in an historical sense) warmed in the past 90 years. It's a fact that the level of CO2 in the air has drastically increased.
The only issues undecided are what the impacta are going to be - we can model and estimate all we want, but only time will tell. I keep hearing the anti-GW crowd yapping it up about all the doom N' gloom predictions - but where are they exactly? Saying it's going to get warmer, and that in turn is going to cause more ice to melt - that's not exactly doom and gloom - it's basically just common sense
In the mean-time, morons like you hold up progress on things like alternative fuel sources, less pollution producing factories, less reliance on foreign fuel sources, cleaner air, etc....all because someone named Gore happened to be the first person in the political spotlight to champion the cause.
Finally - for the AT P&N geniuses that think they have the scientific solutions to global warming - please stop - climatologists have considered all of the possible impacts - that's their job - not someone who just read something on Wikipedia.
