Hey Groggy and Basketcase,
I'm arguing with some Republicans elsewhere. They feel that since CO2 has such a minuscule relative composition in the earth's atmosphere or within water vapor, that it's effect on AGW is negligible. I looked up something on Wikipedia that explains that there was a rise in CO2 in terms of PPM by 40% since 2000 I think, and that CO2 has the greatest impact on UV radiation and the GHE.
Does their argument hold water (no pun intended)?
Think of it this way.
Give your pal 4 drinks and his blood alcohol level might be around 800 PPM and he'll be arrested for drunk driving.
The CO2 level we're talking about is 400 PPM, its enough to make the planet tipsy and get too much of a warm feeling.
Trace amounts do make a big difference.
Take an aspirin and that's only about 3PPM of your body, but it makes you feel better, take about 40 and your up to 120 PPM and you're probably dead.
Hey Moviefan!
I noticed that you've still failed to spot the difference in your heartland institute supplied version and the IPCC legit version.
Its pretty basic, someone with even high school science should be able to spot it.
No wonder you fall for their crap so easily.
Thanks for showing how easy a sucker you are.
