The Economist compares the risk of emitting trace amounts of CO2 to the risk ‘of blowing your head off in a game of Russian roulette’
'Last time round the IPCC said it was likely to be between 2 and 4.5 degrees—meaning there was a 66% chance of its sitting in that range. That left 17% chances that it would be less, or more...And their likelihoods, though low, are not that low: 17% is the chance of blowing your head off in a game of Russian roulette'
