Global Warming - It's Not A Theory

Clean Technica: Global Warming Is Not A Theory. It Is A Measurement.

What is so hard to understand about global warming? It is the same physical process that occurs in a car on a hot day that we all experience. The visible light rays from the sun, distributed in a spectrum determined by the sun’s surface temperature (about 5,500C) easily penetrate the car’s glass windows and are absorbed by the car’s interior which gets warm and often hot to the touch. These warm or hot surfaces then reradiate in a spectrum different from the sun’s radiative spectrum because of their vastly different surface temperatures.
