To those who still doubt Global Warming:
We do know that the Earth is getting substantially warmer on the whole, and the glaciers are getting smaller. One can try to point the finger at other reasons for this, but the fact is that for the past hundred some odd years since the Industrial Revolution, we've been dumping more stuff into the atmosphere -- and on a continuous basis -- than probably in the rest of human history combined. Meanwhile, the theory of global warming seems to have been in place long enough that it should get credit for predicting the changes that are now occurring. I heard of global warming and greenhouse gases as a grade schooler, and I'm in my 40's. So it wasn't an after-the-fact explanation by environmentalists. But blaming "other" factors is pretty convenient for polluters who don't want to change their ways, which means not just industrial giants, but most of us humans in the industrialized world. Hard as it is to believe, the atmosphere holds only a finite amount of air, and the junk billions of people pump into it makes a difference -- same thing for the ocean and the land. So while there may be additional, complicating factors (global dimming from the particulates slowing down the warming from the gases??), I think it's pretty safe to say we've made a mess of a nice planet with our excessive ways. I'm not saying I've just proved global warming, but try on this perspective for a while and see if it doesn't make sense.
