Playing Roulette with Global Warming

The Massachusetts Institute of Technology have issued some seriously educational material about the risks of Global Warming, by contrasting the range of outcomes with and without Policy :-

“To illustrate the findings of their model, MIT researchers created a pair of ‘roulette wheels.’ The wheel on the right depicts their estimate of the range of probability of potential global temperature change over the next 100 years if no policy change is enacted on curbing greenhouse gas emissions.
