This is nothing new, although this article, NoCaste, does lump all the questions into one big pile...
I, being an environmental biologist and botanic, have never believed the "Global Warming" theory, personally.
I do believe that the warming/cooling is a natural phenomenon.

you can get a free e-book, for a limited time, entitled "Global Warming - Global Cooling
Natural Cause Found". It's very interesting!
Peace and Good Will!
