You are no more “right” that either side of the argument, they do not know shit, neither do you. Best guesses is all we get today.

My best guess, the primary cause of warming, storm intensification, glaciers melting ( much faster in the northern hemisphere) the ice extent getting smaller over the North Pole each winter is megapolises, perfect heat storage areas. CO2, nah, if an effect, a thousand times smaller than heat islands. Why is Phoenix hotter longer, CO2? (Laugh out loud!). It is because it is a hundred times larger than it was and has 5 million people here now. Asphalt and concrete store heat all year here, not just in the summer.
