More on Sequestering Carbon

A good article on current and future methods of carbon sequestration for reducing greenhouse gases is “Down with Carbon” (Science News May 10, 2008, pp. 18-23.) The article is written at a level that students will understand. Some promising possibilities for long-term storage include the bottom of the ocean, in sandstone/saline aquifers deep underground, or in volcanic rock formations. There are also some interesting synthetic materials called zeolites in development that can soak up carbon.

Instructors will be interested in the detailed report by the Intergovernmental Panel on Climate Change (IPCC) entitled “Carbon Dioxide Capture and Storage – Summary for Policymakers”. The article has some great illustrations that would be useful in teaching. They can be used free with acknowledgment.
