Scigliano: Global Warming's Evil Twin

We thought we’d heard the last of acid rain, but a story by Eric Scigliano at OnEarth.org is a reminder of that environmental plague of the 1970s. Fossil fuel consumption increases CO2 in the atmosphere, causing global climate change. But it also forces CO2 into our seas, decreasing their pH. In this in-depth investigation on the effect of ocean acidification on oysters, Eric tells us what it takes to run a Pacific Northwest oyster farm, how acidicity can destroy it, and possible solutions.
