> I agree that humans contribute somewhat to it, but to what degree and to what ends, I know we have no clue. You said that you agree the physics of carbon dioxide is well understood. Human activity has drastically altered the net amount of carbon dioxide added to the atmosphere annually (all carbin emissions minus all carbon sink absorptions). We emit a relatively small amount compared to nature, but nature was fairly balanced before by also storing most of that in carbon sinks. Do you not think this is true for some reason? This fact makes it seem pretty apparent to me that we are driving much of the changing temperatures and thus also the changing climate.
