I found this site very interesting. I haven't read all of it yet, though.  They referenced all the information that they used. This petition has been signed by around 17,100 scientists. Sorry if its already been posted.

 

One of the things I found interesting is that humans adding CO2 to the atmosphere is actually HELPING plant and animal life. Moving Carbon from under the earth's surface (where its oil, natural gas, etc.) to the atmosphere allows it to be converted into living matter like plants. Very cool!

Oregon Petition really has about 17 000 signatories, but according to a survey conducted by Scientific American, only about 200 climatologists (extrapolation) on the list agree with the statements these days: http://www.sciam.com/page.cfm?section=sidebar&articleID=0004F43C-DC1A-1C6E-84A9809EC588EF21

Yes, CO2 leads to faster plant growth rates, but it is also poisonous in large quantities, in addition to being a greenhouse gas. For example, if you're closed for a long enough time in an air-tight space, you don't die to the lack of oxygen, but to CO2 poisoning because CO2 replaces the oxygen in your blood. That's because the CO2 concentration goes up as you exhale it. We're basically doing the same to the environment with adding CO2 to atmosphere from outside of the natural cycle. There's only so much CO2 that the ecosystem can handle.

You mean like the 8,000 PPM when the dinosaurs were around? As opposed to the 380 PPM nowadays?
