Scientists debate carbon sequestration and geoengineering options

This week’s issue of Nature Geoscience (cover —  “Locking carbon in minerals”), timed to coincide with Copenhagen climate talk preparations, carries a focus on carbon sequestration.

Contributors include Phil Boyd of NIWA and University of Otago, who weighs in on the geopolitics of geoengineering.

Other articles and commentaries look at mandatory sequestration linked to fossil fuel extraction, air capture of CO2 (here and here), and trends in the sources and sinks of carbon.  The importance of agricultural emissions for Europe’s greenhouse gas balance is argued. Views on options for sequestration, including mineral and deep ocean, are also discussed.
