Marine Cloud Brightening – A Governance Dilemma

A virtual side event for the
UN Ocean Conference 

1 July 2022 at 11:00 WEST – 12:15 WEST

This event was recorded on 1 July 2022, and will also available with interpretation into 中文, Español and Français.

The Carnegie Climate Governance Initiative (C2G) and the Joint Group of Experts on the Scientific Aspects of Marine Environmental Protection (GESAMP) held this virtual joint side event, ‘Marine Cloud Brightening – A Governance Dilemma‘ on 1st July 2022, 11:00-12:15 WEST; during the UN Ocean Conference, held between 27 June-1 July 2022. 

Actions and commitments made by countries under the Paris Agreement are insufficient to keep the global warming below 1.5 degrees Celsius to avoid catastrophic climate change, some vulnerable places in the world are already facing greatest impacts – the Great Barrier Reef has been severely damaged by marine heatwaves caused by climate change and is currently suffering its sixth mass bleaching. The IPCC 1.5 SP report predicted that up to 70% – 90% of coral reefs will have disappeared at 1.5C, more than 99% would be lost at 2C. To reduce bleaching on the reef, a group of Australian researchers and engineers are exploring and conducting outdoor experiments to test marine cloud brightening (MCB) locally which seeks to whiten clouds over the ocean to reflect solar radiation back into space in order to achieve cooling.   

MCB, is one type of solar radiation modification (SRM), that may have the potential to protect the marine environment by reducing climate hazards, but it could create novel risks, ethical and governance challenges – particularly if scaled up in a global climate intervention. An outstanding challenge is the governance of its research, in particular concerns about research that might put society on a “slippery slope” towards deployment and create distractions from the essential focus on emission reductions and removals.  Meanwhile, scientists,  policymakers and societies across the world do not know enough about its potential benefits or risks to be able to make well informed decisions about its potential development or use. How to deal with this dilemma?  How do we weigh up those concerns and the risks of not knowing whether or not SRM might be a potential additional climate response option? Can society learn from the MCB project that might advance the governance of SRM research?  

This event brought together guest speakers from different backgrounds to share their insights on these challenging questions as a contribution to the thematic 3: Minimizing and addressing ocean acidification, deoxygenation and ocean warming.

Phillip Williamson, Honorary Reader, School of Environmental Sciences, University of East Anglia

Phil Williamson has mostly worked for the UK Natural Environment Research Council (NERC, now part of UK Research and Innovation), based at the University of East Anglia as a programme Science Coordinator.  His main areas of expertise are in global climate change – how it affects natural systems and society, and what we can do about it – and ocean biogeochemistry, including the ocean carbon cycle and marine ecosystems. 

Following initial research in the 1970s on invertebrate ecology (both terrestrial and marine), Phil led the planning and implementation of a wide range of national and international research initiatives, including work for Plymouth Marine Laboratory and the International Geosphere-Biosphere Programme. Topics included marine zooplankton dynamics, microbial biodiversity, ocean-atmosphere interactions and climate geoengineering.   

Phil’s work for NERC at UEA included science coordination of the UK Ocean Acidification research programme (co-funded by NERC, Defra and DECC), the Shelf Sea Biogeochemistry programme (co-funded by NERC and Defra), and the UK Greenhouse Gas Removal programme (co-funded by NERC, other Research Councils and BEIS).  Phil has led two reports on climate geoengineering for the UN Convention on Biological Diversity (CBD); has co-authored reports on ocean fertilization for the Intergovernmental Oceanographic Commission (IOC-UNESCO) and on ocean acidification for OSPAR and the CBD; and was a lead author for the Intergovernmental Panel on Climate Change (IPCC) Special Report on Ocean and Cryosphere in a Changing Climate, also its Summary for Policy Makers and Glossary, all published in September 2019.  His current research interests focus on the role of the ocean in carbon dioxide removal, including the effectiveness of coastal ‘blue carbon’ as a nature-based climate solution. 

Phil has authored more than 100 other scientific publications, including six in Nature.  Together these have achieved more than 3,500 citations.  He has given many interviews for television (including BBC World News, Sky News and CNBC), radio (BBC R1, R2 and R4, Talk Radio, CBC and many regional radio stations) and print media, and has written articles for The Conversation and the popular press (including The Spectator).
