Lee Felich has covered this in his post on the subject. To restate: CO2 resulting from burning fossil fuels has a unique isotopic signature. Not saying that volcanic activity doesn't contribute to CO2 loading but you'd think it was part of the normal "background" variation that can be accounted for in the quoted known CO2 record over the last 800,000 years.
Everyone should reread Lee's post carefully if they didn't the first time through. It is well reasoned and covers the bases on the global warming discussion. Nice touch that Lee can't get funding for climate research :-) Thanks Lee!
