Do you know what is under the sands of the Sahara desert? River beds, forests, savannahs, grass plains like the midwest and signs of civilization. Do you know why it's now a desert instead of all those things? Climate change. Denying that climate changes happen is rather, er...thoughtless. And denying science in general when you have no grasp of it is, er...not conducive to your long term survival. You are fated to future disappointment and chagrin, don't you ever get tired of being wrong about everything all of the time?

I don't think any thoughtful person believes climate never changes, nor do/would they 'deny science'. Some of you people are so condescending it's pathetic. What you've pointed out is common knowledge and should serve as an example for you not me. There's nothing you can do to stop these things from happening. Laying a guilt trip on mankind and declaring people to be the cause of something that's obviously been an ongoing process is wrong. People are being exploited on a mass scale... they appeal to their better side to get them to join a crusade that will lead them into poverty and substandard living conditions. The fact that they get them to do it willingly and happily is devilish in the extreme. In my mind, you're destined to become the Eloi.
Whatever.
