Hack the Planet

David Battisti had arrived in Cambridge, Massachusetts, expecting a bloodbath. So had many of the other scientists who had joined him for an invitation only workshop on climate science in 2007, with geoengineering at the top of the agenda. We can t take altering the atmosphere seriously, he thought, because there s no way we ll ever know enough to control it. But by the second day, with bad climate news piling on bad climate news, he was having second thoughts. When the scientists voted in a straw poll whether to support geoengineering research, filled with fear about the future, Battisti voted in favor of it.

While the pernicious effects of global climate change are clear, efforts to reduce the carbon emissions that cause it have fallen far short of what s needed. Some scientists have started exploring more direct and radical ways to cool the planet, among them pouring reflective pollution into the upper atmosphere and growing enormous blooms of algae in the ocean. Schemes that were science fiction just a few years ago have become earnest plans being studied by alarmed scientists determined to avoid a climate catastrophe. In Hack the Planet, Science magazine reporter Eli Kintisch looks more closely at this array of ideas and characters, asking if these risky schemes will work and just how geoengineering is changing the world.

Scientists are developing geoengineering techniques for worst case scenarios. But what would those desperate times look like? Kintisch outlines four circumstances in which climate change could be quick and cataclysmic: collapsing ice sheets, megadroughts, a catastrophic methane release, and slowing of the global ocean conveyor belt.

It takes compelling characters to come up with Earth cooling ideas like making cement from coal plant exhaust, spraying a fine mist over the entire Middle East, and spraying gas from airplanes to make shade. Kintisch takes readers from a geoengineering expedition on the frigid Southern Ocean to the halls of conservative think tanks to profile the players in this emerging field, including Russia s Yuri Israel, Edward Teller s former protégé Lowell Wood, and David Keith and Ken Caldeira, informal coleaders of the Geoclique that conducts and encourages geoengineering research. Kintisch tackles the scientific and geopolitical issues involvedincluding the dubious arguments for geoengineering in SuperFreakonomics.

As incredible and outlandish as many of these plans may seem, could they soon become our only hope for avoiding calamity, or will the plans of brilliant and well intentioned scientists cause unforeseeable disasters as they play out in the real world? And does the advent of geoengineering mean that humanity has failed in its role as steward of the planetor taken on a new responsibility? Kintisch lays out the possibilities and dangers of geoengineering in a time of planetary tipping points. His investigation is required reading as thedebate over global warming shifts to whether humanity should Hack the Planet.
