I don't know, that all up for questions, I think (for already stated reasons). When you cover the entire land of the Earth with concrete, steal, or gravel, you have to wonder if that is causing a temperature impact. It seems more likely than focusing on our tiny impact to normal CO2 cycles, mostly based on one study in the '70's and a steady flood of deceptive use of data with misleadingly framed charts all coming generally from one source.
