Put It Back: Geologic Sequestration for Greenhouse Gas Emissions Reductions
March 1, 2011 at the Austin Forum
In this talk, Dr. Tip Meckel discusses one of the promising but little known options to reduce atmospheric emissions of the greenhouse gas carbon dioxide (CO2). Oxidation (by burning) of carbon stored in fossil fuels—coal, oil, gas—has transferred more than 250 billion tons of carbon into the atmosphere since 1800. Changes in atmospheric concentration of CO2 show that the rates of emission exceed the rates of uptake, resulting in increases of atmospheric CO2. Fossil fuel reserves and rapidly growing global energy demand suggest that continuation of “business as usual” will result in rapidly increasing concentration of CO2 in the atmosphere. A variety of risks ranging from increased average temperature to decreased pH of ocean surface water are predicted from this change.
