Even though you've already been thoroughly debunked, I feel the need to chime in about this global cooling malarky.
See, there are two types of gasses that make a difference to these discussions. Carbon oxides and sulphur oxides. Sulphur oxides reflect heat, so warmth from the sun bounces back out into space and the earth cools down a little bit. Fortunately for us, scrubbing our exhaust gasses and purifying our fuels meant that we could stop pumping suplhur oxides into the atmosphere. Yay us!
Carbon oxides behave a little differently, they absorb heat, so any heat that would be radiating out gets caught by the carbon oxides and makes them wiggle a little faster, which warms up all the air around it. Unfortunately, no one has come up with an "easy" way to stop pumping carbon oxides into the atmosphere, everything we have would require us to change what we are doing. We don't want to change, so the science telling us about it must be wrong.
