Let's do the experiment, and see how inaccurate the climate models are.

Lets keep burning peak oil like gangbusters, enriching the Saudis & Iranians who hate the west even further, throw in some liquified coal CO2 for good measure, avoid taking any actions that might adversely effect Exxon/Mobil profits, and see what happens. We will need to keep track of how hot it gets, how much the seal level rises, how much the hurricane strengths & damage increase, how much drought intensifies and food production decreases, and of course we'll need to count the excess deaths.
