Can the climate be hacked to keep the Earth's surface temperatures manageable? Can we get away with hijacking natural cycles (emulating volcanoes, pumping nutrients into the oceans, tinkering with the solar reflectivity of clouds) without radically screwing up weather patterns—or starting a war? Or is it a cop-out even to talk about this, rather than focus on kicking ass and taking names on the carbon emissions front?
Huh? Did he say "war"? Well, since climate heeds no human boundaries, any serious intervention by scientists could require a level of global cooperation that makes Copenhagen look like a cakewalk—and we all know how that turned out. If any country were to start testing this stuff unilaterally on a big scale, let's just say it would not be terribly popular.
But all the technical, cultural, and political roadblocks didn't dissuade leading geoengineering researchers from attending last week's big powwow at the Asilomar Conference Center—a longtime science haven and site of a similar meeting on genetic engineering back in 1975. Like that historic meeting, this one's ostensible purpose (activists envision something more nefarious) was for the scientists to discuss possible ground rules for future experimentation and for navigating, well, the technical, cultural, and political roadblocks. And like that meeting, this one has been criticized as an attempt to legitimize a potentially dangerous area of science.
Not to say the attendees were all gung-ho to put their ideas into practice. As climate scientists deeply concerned about human contributions to global warming, most were somewhat wary about the implications of climate hacking. That's one thing reporter Jim Rendon learned when we sent him to Asilomar to check out the scene. His dispatches below, and their links to our past geoengineering coverage, will give you a sort of Climate Hacking 101. Considering the world's inaction on addressing the most pressing problem of our time, you'll need it. We're all going to be hearing a lot more about human volcanoes and so on in the not too distant future.
Dispatch 1: Geoengineering Bad Fixes for Worse Problems
As climate-intervention scientists meet, fans see a Plan B where critics see a delay tactic.
Dispatch 2: Who Eats Geoengineering Risk?
Any large-scale test would require true international cooperation.
Dispatch 3: Do We Test Geoengineering?
Any meaningful field run would be a contentious, high-risk venture.
Dispatch 4: Geoengineering for Fun and Profit
Should scientists—or anyone—be allowed to cash in on high-risk climate fixes?
