I *do* hope you're not falling into the trap of believing statements and conclusions made by a corporate-sponsored study on AGW! After all, we all know how misleading and worthless all those Exxon-supported studies were (hint: they reached the 'wrong' conclusion). After all, it is widely accepted and acknowledged that scientific research is only valid when it is funded by government taxation, and never by private business concerns. That would be another Proof by Consensus, right? ;-)
You - honestly and very correctly - touched on the subject but I'll step out and say it plainly - I seriously doubt Deutsche Bank believes or even cares about carbon footprints and impacts on the environment. What they *really* want is an opportunity to make gobs money buying and selling an imaginary product ('carbon credits') that world-wide consumers / taxpayers will be forced to purchase. Being a skeptic (aka heretic), I doubt their 'study' has *any* other purpose - if there was a program to buy/sell 'Whale Credits', they'd discover a sudden urge to 'protect this noble and intelligent species'. Regardless, yet-another survey of scientists and opinions proves nothing (Argument by Authority, again).
But I *could* be wrong. I'll read the 51-page PDF and respond soon... we'll see.
