The magnitude of the global climate crisis is such that even the most committed environmentalists are liable to live in a state of denial. The award-winning writers collected here have made it their task to shake off this disbelief, bringing the incomprehensible within our grasp and shaping an emotional response to mankind's unwitting creation of a tough new planet. From T.C. Boyle's account of early eco-activists, to David Mitchell's vision of a near future where civilization dwindles as oil sells for $800 a barrel - these stories blend speculative and literary fiction and range across time. The aim is to make the danger posed by climate change as accessible to the imagination as subjects more common to the best of contemporary fiction. Royalties from I'm With the Bears will go to 350.org, an international grassroots movement working to reduce the amount of CO2 in the atmosphere.
