There was a Horizon programme about this theme some months back. The sceptics (or pillocks) strongly believe that one unsubstatiated hypothesis is enough evidence to counter overwhelming scientific evidence.

To the effect - "My opinion is possible, therefore it must be true and therefore all other evidnece must be false".

Has anyone thought through that in the end it is the wealthy who don't give a f*** if they destroy the planet as it is a problem for later generations, and in their view it would vbe better for a couple of billion p[eople to die than have to change their lifestyle."

Maybe then it is the biilions who are being selfish, how dare they expect to have water or a climate that sustains life if it robs some magnate of a few dollars!
