You left out the pollution-caused Global Dimming that masks (for the time being) the massive temperature-increasing impact of humans burning carbon, especially at 30,000 feet and producing jet 'condesation trails' that act as a giant sun-screen.
Global Dimming means we have coal and oil TIGER by the tail.
If we drastically cut CO2 emissions, the world's man-made sunshade of air pollution will vanish and termperatures will suddenly rise to intolerable levels.
If we don't drastically cut CO2 output, the world's man-made sunshade of air pollution will stay aloft and termperatuers will rise slowly to intolerable levels.
If you doubt the validity of jet con-trails acting as a giant sun-shade, go to this increbible site:
