The sad thing is everyone will suffer because certain groups found it in their interests to lie and slander to cover up the science and their responsibility.

While a few useful idiots still regurgitate the dogma that AGW is some commie plot, and that we only have Al Gore's word for it - it is clear the entities that fed them these lies KNEW better...

For those that claim the scientists and NASA are somehow cashing in by engaging in a conspiracy to sell the idea of AGW, that is completely delusional. Exxon profits in 2012 were ~45 Billion dollars-

NASA's entire budget is less than half that... Denying the fact human emissions are warming the Earth is no more valid than the Flat Earthers claims, or those claiming we never landed on the moon... the fact that they have to resort to the slanderous and laughable claims of a vast conspiracy demonstrates just how for from reality they have become.

We all will suffer the consequences for this malfeasance and stupidity, but it will be the poorest of the world that will suffer disproportionately... so its not really Karma... its a crime.
