Artful Dodger:

Of course, you realize that global warming is not about daily or seasonal weather events, but rather about the long-term averages of atmospheric temperatures. This winter is actually not that cold, at least not here where the temperature is almost 20 degrees higher than usual. That is not what global warming is about. It is about an increase of almost 2 degrees in average atmospheric temperatures over the last 100 years and the fact that those increases in temperature coincide with the burning of fossil fuels on a massive scale. Are fossil fuels to blame for global warming? Only if one sees a correlation between burning of fossil fuels and the increase in atmospheric long-term averages since the start of the industrial revolution. Just because winter is cold it does not mean that all that carbon dioxide has no effect on the atmosphere. The question is not whether this winter is cold or not, but rather whether average winter temperatures have increased in the last 200 years.

Of course, if global warming does not exist, then it is ok to keep burning fossil fuels and polluting the atmosphere. After all, car and factory exhaust fumes are really harmless!
