Change Is Good (Maybe)

Sharyn Hedrick

Really, who knows what all the effects of climate change will be? One thing triggers another, which triggers another, and some of it can be predicted on the basis of past and current reactions, and some of it simply can't. One scientist thinks he's found a possible positive effect. The melting glaciers, he says, are releasing iron into the ocean, which may, under the right circumstances, feed phytoplankton. The phytoplankton, in turn, trap carbon dioxide: http://cosmosmagazine.com/features/may-bright-side-glacier-melt/
