Hah - I only meant your reputation as a prolific and highly rated commenter. As for my response... you seem to have made a few presumptions about what I believe. Your comments about "all at once" restoring a pre-1900s atmospheric level, or humans ever having been able to "dial in" a climate aren't reflective of what I feel, fwiw. As the question you asked, I mentioned the closed system/sequestered carbon because I don't think it's valid to include carbon that has been removed from the atmosphere (CACO3, coal deposits, etc) when talking about a normal climate cycle. I don't entirely understand the differences in the framing at the end, either. If you believe we need to reduce CO2 emissions, then we're in agreement. And regarding the postscript - I didn't mean to be pedantic, nor am I an expert in the subject. I was just pointing out the discrepancy, and I probably didn't have to, so my apologies there.
