Duf: You need to learn more about the actual problem. Its a complex topic, but average temperatures do exist and they do go up and down even from year to year, but if you compare all the averaged temperatures over an extended period of time, the warming is unequivicol and quite extreme. Think there were warm spells and cold spells along the way and things cycle? There were and are and things do cycle, but even with those small variations the overall temp keeps moving up and up and up. Unfortunately many people like yourself simply think in terms of single temperatures vs. sustained warming with small ups and downs along the way.

There are of course local variances...this winter was cold right? So we automatically assume that the farther north we would go, the colder it would get, unfortunately thats not the case, there were cold areas over Europe and Asia, due to normal cycles like el-nino, but up north in the arctic its been down right balmy. You need to think on a global scale. For instance about 90% of the earth's glaciers are melting rapidly, however there are areas where they are growing becuase warming oceans are humidifying local air masses leading to more snow in a few select areas which are actually growing some glaciers. But that's like saying 90% of me is being eaten alive by a tiger, but at least 10% of me is ok... not great logic.

I also understand your confusion with "global cooling," however that was a real concern caused by the emission of ozone, and the growth of the ozone hole, a once common pollutant that breaks down our atmosphere and was eliminated from common usage thanks to a united effort by the UN. Its in effect the exact opposite, but equally as real problem from the emission of greenhouse gasses which trap heat next to the earth.

I urge you to do some more, even very very basic research... start here: http://www.pewclimate.org/global-warming-basics

and even if you question or don't understand the science, isn't it about time we got off foreign oil and dirty coal anyways? Clean energy is good for national security, good for jobs and good for the environment, need anything else?
