It's called global dimming- and it's happening at the same time that global warming is happening- mitigating some of the effects. Clouds (and other particles- eg. aerosols) in the atmosphere blocking sun rays- those rays still contribute to global warming but not as much as ones that make it to the ground. Speeding up global dimming is a horrible idea....you're basically increasing the amount of particulate matter in the air, not to mention the decreased amount of sunlight for vegetation, which has an effect on every living organism...
And what is with people arguing against global warming by saying it's happened before...nobody who believes in global warming (worth their salt) is denying that the earth's temperature moves in cycles. There is a natural fluctuation of greenhouse gases on earth- going along with a natural fluctuation of plant and animal life. The earth as a system is set up to handle it's own carbon cycle. However- free millions of years worth of trapped carbon in a matter of hundred years- there's no way that doesn't mess things up... could somebody please explain how they view this having no (or little) effect?
