I enjoyed it, especially amused by the confused guy who was traipsing all around the world, trying to help stop the terrorism, nearly falling to his death in an ice crevasse in the Antartic, nearly getting eaten by cannibals, etc. etc. Escapist fiction. ;-D
But the science was excellent, and I really enjoyed that.
I suppose the computer models which predict all the scary scenarios are making an assumption that CO2 emissions in the future will be not only increasing arithmetically, but multiplying over the years.
If so, that is probably not the case, as emissions in the US, for instance, have apparently already plateaued.
