Please don't get me wrong, I'm all for clean energy and protecting the environment but not at the expense of sane, rational, clear thinking. But the hype that surrounds the "Global Warming" bandwagon makes me deeply suspicious.
Perhaps its because I'm old enough to remember the hype around "Global Cooling" in the 1970s that led to the banning of CFCs. Back then we were all going to freeze to death and the Australian Great Barrier Reef was going to be destroyed before the end of the century. Well, the century came and went and that little piece of propaganda was conveniently forgotten. Apparently, Global Warming will destroy it by 2020.
I won't be surprised if our grandchildren look back on us as the generation of Henny Penny, the Post-Cold War generation that lacked a super villain and so got all upset about the sky falling.
Anyway, the guts of this post is to point you to an obscure comment by National Geographic that points out that Mars has warmed by roughly the same amount as the Earth over roughly the same period of time.
Evidently, the Martians aren't looking after their planet either.
As a side note, author Michael Crichton has an interesting perspective on all this
