Past Event

Seminar: "Ocean fertilisation - can seeding new life in the ocean absorb our excess carbon?"

This seminar is hosted by the Oxford Geoengineering Programme

Algal Bloom PhotoSummary: The proposed geoengineering technique of ocean fertilisation involves adding nutrients to enhance the ocean’s capacity to draw carbon dioxide out of the atmosphere. The theory is that by providing certain nutrients to those parts of the ocean that are deficient in them, we can seed new life that will ‘feed’ on carbon dioxide from the atmosphere. But what are the risks of these proposals? How would they affect the balance of life in the oceans? What is technically feasible and what kind governance structures would be required to regulate such activities.

This event is part of a series:

Geoengineering Seminar Series: “The science, governance and ethics of climate intervention techniques.”

This seminar series is hosted by the Oxford Geoengineering Programme Geoengineering - the deliberate, large-scale intervention in the Earth's natural systems to counteract climate change - is a controversial subject. This series of seminars will explore the science behind proposed techniques and address their potential impacts and side-effects - both environmental and social. Each...
