Potential and risks of Carbon Geoengineerin.

Multiple options have been proposed to deliberately enhance the storage of carbon in natural reservoirs, and thus reduce the magnitude of climate change and/or the efforts otherwise needed to reduce greenhouse gas emissions directly. These ‘Carbon Geoengineering’ options range from afforestation to bio-energy with carbon capture and storage to ocean iron fertilisation. But what is their potential (and their costs!), and what are the possible unintended consequences? This lecture will give an overview of the current understanding on this rapidly moving topic.
