And you have proof for this statement? Ever before is a long time. It seems to me that there have been all sort of effort to curb CO2 emission and now you are telling me that nothing we have done has done any good at all. Just why should anyone even bother to try?
What about when volcanoes erupt? Just a drop in the bucket compared to what my car spews out. I think not.
Or maybe, CO2 is not the problem. Just maybe there is no problem. Good news is always natural a phenomenon, but bad news is always caused by humans. Is that your theory?
If you were to look back at my (multitudinous) posts on this subject — you'll see that my bona fides are in order. We're in total agreement on the subject.
