Nah, global warming is a fallacy. We've only been keeping track of the weather since the 1890's. It's a natural cycle. How can anyone know what the temperature fluctuations have been like before that, barring geological knowledge of ice ages and other very extreme temperature changes? The Earth cools down, it gets hotter, etc. IMO (and in the opinion of many scientists) global warming can in no way be proven or validated. It's cyclical. That is not to say that we should not do our best to protect the environment, but the global warming theory is tenuous at best.
