Unfortunately, the physics and chemistry are real, and factual. The title of Al Gore's book was rather apt, "An Inconvenient Truth".
As an aside, Gore was making reference to a much earlier quotation from muckraker novelist Upton Sinclair: 'It's hard to understand something when your paycheck depends on your not understanding it.' This is sometimes cited as Upton Sinclair's Law -- most frequently by political conservatives. The man was, among other things, a keen observer.
Dismissing it as opinion sells you and the rest of us short.
I still think Andrew should put his money where his mouth is. Talk is cheap; investment requires commitment. (In general, one of the quickest ways I have of dispelling humbug is to say 'Shall we make a wager on it?')
