When we wake up to the truth, we will see all-out conversion to clean, renewable energy as an absolute necessity, the equivalent of WWIII. The plan is explained in *The Present* @ TruthContest (.) com, check it out, what this book says will blow your mind and turn our world right-side up.

Joe Bastardi? Who claimed that the Arctic was going to go back to normal in his 2012 summer sea ice extent prediction and then looked like a fool as it decreased in 2012 and smashed the record in 2013 for lowest extent. Yea...follow him.

James Hansen is truly the Messiah of Environmentalism. The non-believers should be cleansed ! We could even team up with the middle eastern muslims against our common enemy, the pro westerners in American and Europe.

Are you saying that the at times hypocritical or misguided actions of one man are proof that a concept involving the entire earth is invalid?
And who is really making the money?
The handful of small energy companies making millions promoting electric cars, solar panels, and other new ways of obtaining energy...
or the multiple oil companies making BILLIONS...promoting that Climate Change is a joke is great for their business!
