But that is THE problem. It has to get that bad and even now with all of the evidence out there people still deny that we have any impact at all. People will be rowing to work denying it still. Whatever happens has nothing to do with our precious oil and gas, you know that stuff that makes a few people rich enough to impact elections and keep naive people skeptical about it.
How many deniers would you have if we had renewable energy already in place before discovering oil as a power source? I bet none.
