It's fairly straightforward when you look at a simplified model. It's sort of the opposite of what clouds do. The really complicated part of it is when you look at a a 3-d model of the entire atmosphere and the earth's surface.
What is true is that natural effects like solar activity can overwhelm the effects of what we do by putting more CO2 in the atmosphere. But, the "global warming" that we are concerned with is superimposed on top of the natural cycles.

I think my main gripe is the fact that they blame it on our activities, if it is indeed happening. If it is happening and if we are causing it, I wish the politicians would stay out of it and quit using it to promote their agendas, such as cap and trade and numerous others. They try to guilt us into buying into their agendas. Then it becomes rep vs. dem and there goes the price of all of our commodities. Then they try to start raising taxes to take even more, all in the name of whatever their current agenda happens to be.
