A year ago, I blogged about a famous book called "SuperFreakonomics" by Steven Levitt and Stephen Dubner (read my review here). One chapter in their book titled "What Do Al Gore and Mount Pinatubo Have in Common?" is all about solutions to climate change. In this chapter, Levitt and Dubner specifically embrace geo-engineering solutions which are highly controversial in climate change circles. One of the wild and far fetched geo-engineering ideas reported, evidently thought of by Intellectual Ventures, is the garden hose to the sky:
"A team of British researchers called SPICE (Stratospheric Particle Injection for Climate Engineering) is trying to pump particles of water into the atmosphere as a test run before moving onto sulfates and aerosols that would reflect sunlight away from earth, mimicking the aftereffect of a massive volcanic eruption. SPICE is building the garden hose at an undisclosed location, with £1.6 million in U.K. government funding and the backing of the Royal Society".
Essentially a long garden hose from the Earth would pump sulfur dioxide into the stratosphere to allow for a cooling effect.
Sound a little nuts to you? This is one of many geo-engineering ideas out there. Amid the ambivalence about how to mitigate GHGs and adapt to climate change, geo-engineering nerds and fanatics are proposing solutions that, while controversial on the surface, may have some merit if we explore our curiosities and gamble with risks. I am skeptical of geo-engineering myself but am interested nonetheless.
