bbjsw10,
BlackDeuceCoupe,
you BOTH are right.
Ever here of Global Cooling? It is an effect first noticed by farmers when the pan evaporation rate slowly started decreasing around the world. There are hundreds of years of data on the pan evap rate. Global cooling is the effect that particulate matter in the air from the last 200 yrs of burning coal and other nasties has decreased the amount of sunlight reaching the surface, hence decreasing the pan evap rate. This effect was balancing out the increase in GHG until we started decreasing particulate matter emitted from the things we burn, say around the 60's or so. Since then, the worlds major power plants have become cleaner, allowing the human induced global warming effect to be seperated for the natural effects.
