I agree with BKBrown on this. "Global Warming" is just the earth's natural cycle and nothing new. Its just something for the environmentalists to latch onto to spread fear and their agenda. Studies have shown the earth's average temp has actually decreased by 1.5 degrees (I believe that was the number) over the last decade, yet the believers still scream the earth's gonna burn up because some cow farted somewhere. I'm not saying we shouldn't, within reason, do what we can to preserve the environment, but we can certainly do it without being alarmist and running around screaming the sky is falling.
