Red Earth, Green Earth, Blue Earth

You know what might forestall climate change? We could add iron to the ocean, spurring massive phytoplankton blooms that would sequester CO2 to the icy depths. Or might not. An Indo-German led team has set out to spread 20 tons of iron sulphate across a 115 square mile area of the Scotia Sea near Antarctica to test this idea.

As a bonus, it may promote more zooplankton, which would help the Antarctic ecosystem, particularly penguins, seals, and whales.

Of course, it is experimental. The image above is from ETC Group, who are not down with it.
