Eli Kintisch, Point of Inquiry guest (listen) and the author of Hack the Planet, was on "All Things Considered" yesterday. Here's an excerpt from the show transcript:
Another scientist is taking a different approach to geoengineering. Instead of looking to the sky for solutions, he's looking to the ocean. Victor Smetacek, a German oceanographer, is trying to cool the planet by growing carbon-absorbing gardens in parts of the ocean with little life. In 2009, Smetacek and a team of Indian and German scientists added 6 tons of iron into a section of the Southern Ocean, which rings Antarctica, to see if they could get a massive bloom of algae to flourish. Algae growing in the ocean cools the planet by sucking in carbon dioxide. The team did get algae to grow, but it was the wrong kind of algae. The 10-week experiment, called project LOHAFEX, is the world's largest geoengineering ...
