Global warming? Well, here in Canada we see it as something kinda nice, especially in January. Just kidding.
I am not overly concerned about it because there is little or nothing we can do. The climate trend we call global warming will reverse itself when the earth eliminates the parasite known as man. Combatting global warming is not about saving the earth. The earth will go on regardless of what we do about it. Combatting global warming is about saving humans. However, if we were serious about it, we would reduce the number of people significantly to get back into a natural equilibrium. If we don't do it, nature will with famines, floods, plagues, etc.
