re: #333 danrudy
IF you consider how much co2 and heat is thrown in to the atmosphere in only one volcano eruption or from naturally occuring forrest fires from lighting strikes the amount of production by man is peobably miniscule.
I think we give ourselves much to much credit for our ability to change levels. Nature can do it much faster and efficiently.
Sorry, my man, we have increased CO2 levels by 33% over anything we have been able to record over the last 400,000 years when lightning, forest fires, and volcanoes were constantly doing their thing. This one is on us.
