I can only imagine that if Al Gore has invested 10% in Chicago Climate Excgange it could be argued he is putting his money where his mouth is.
Say he did not believe in AGW but just wanted to make money out of it - and then if the evidence year after year just was not adding up i.e temps started drifting down to the long term average or we entered an ice-age - he would really be stuffed - the exchange would be shut down
Similarly with Goldman Sachs - I think they would only invest their dosh after a lot of research to say they were on the right horse
You could argue there is a massive world-wide conspiracy but I can't accept that - too many diverse people - the internet - the truth would come out
So the fact they put their money where their mouth is does not concern me
But I should ask you about the petro-chemical industry - they have made huge investments yet many are accepting AGW warming (after years sponsoring the stallers)
Why would they do that ? human nature would suggest they stick with the sceptics unless the evidence was just too compelling
