Climate chaos is inevitable. We can only avert oblivion

Sometimes we need to think the unthinkable, particularly when dealing with a problem as dangerous as climate change – there is no room for dogma when considering the future habitability of our planet. It was in this spirit that I and a panel of other specialists in climate, economics and policy-making met under the aegis of the Stockholm Network thinktank to map out future scenarios for how international policy might evolve – and what the eventual impact might be on the earth’s climate. We came up with three alternative visions of the future, and asked experts at the Met Office Hadley Centre to run them through its climate models to give each a projected temperature rise. The results were both surprising, and profoundly disturbing.
