I´m surprised the Earth's net reflectivity, or albedo, hasn´t entered this discussion until now.

A 1997 UCLA study showed that Los Angeles is 5 degrees Fahrenheit warmer than the surrounding areas. Because of the traffic causing more CO2 in the air? No, it´s because mostly due to dark roofs and asphalt. Cars and power plants contribute, but only a bit; at high noon, the sun delivers to each square mile the power equivalent of a billion-watt electrical plant.

A mere 0.5 percent change would solve the greenhouse problem completely. Problem is that 70% of Earth is water and that absorbs more light than it reflects.
