The size and severity of the global climate crisis is such that even the most committed environmentalists can drift into a state of denial. The award-winning writers collected here have made it their task to shake off this nagging 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 Nathaniel Rich's comic fantasy about a marine biologist haunted by his youth, and David Mitchell's vision of a near future where oil sells for $800 a barrel - these ten provocative, occasionally chilling, sometimes satirical stories bring a human reality to disasters of inhuman proportions.

Royalties from the sale of I'm with the Bears will go to 350.org, an international grassroots movement working to reduce the amount of CO2 in the atmosphere.

With contributions by Margaret Atwood, Paolo Bacigalupi, T.C. Boyle, Toby Litt, Lydia Millet, David Mitchell, Nathaniel Rich, Kim Stanley Robinson, Helen Simpson, and Wu Ming.
