MIT Spectrum - Winter 2007

There's one basic answer to the question, Why are we worried about energy? The answer is climate change, argues MIT's Ron Prinn: if there were no global warming threat associated with fuels like oil and coal, there'd be no crisis.

We developed the Greenhouse Gamble™ wheels to convey uncertainty in climate change prediction. Each wheel represents a different set of greenhouse gas policies, and each slice shows the likelihood of temperature change in that range by 2100.
