This post is by Martha Roberts, an economist at Environmental Defense. It’s the first of a three-part series on carbon sequestration – storing carbon or carbon dioxide (CO2) in soils, trees, geological formations, and oceans.
1. Biological Sequestration
2. Geological Sequestration
3. Ocean Sequestration
Global warming is occurring because – day after day, hour after hour – human activities pump large amounts of greenhouse gases into the atmosphere. One way to decrease emissions is to store carbon or CO2 someplace other than the atmosphere.
There are two vastly different ways of sequestering carbon: biological and geological. The topic of this post is biological sequestration, which is among the biggest of the "low hanging fruits" for making quick, substantial cuts in emissions.
