Oh and a great article on wired about 'hacking the planet'

http://www.wired.com/wiredscience/20...ktheplanet-qa/

While humans have unintentionally been altering Earth’s climate for centuries, some scientists have begun to study how to intentionally hack the globe to cool the overheated planet.

Eli Kintisch’s new book, Hack the Planet provides a thorough and nuanced portrait of the development of geoengineering. Through long acquaintance with the field’s biggest names, Kintisch, a staff writer for Science, paints a deep sociological portrait of a radical new scientific discipline bursting messily into the world.
He reminds us that even though the techniques may be wild and global, many of the people dreaming them up are regular scientists trying to deal rationally with a carbon problem that they don’t see society solving. Faced with a warming world, they are torn between watching nature die or trying to surgically kill it themselves.
