The Centre for the Study of Existential Risk (CSER) is an interdisciplinary research centre within the University of Cambridge dedicated to the study and mitigation of risks that could lead to civilizational collapse or human extinction. Our research focuses on Global Catastrophic Biological Risks, Extreme Risks and the Global Environment, Risks from Artificial Intelligence, and Managing Extreme Technological Risks. Our work is shaped around three main goals:

• Understanding: we study existential risk.
• Impact: we develop collaborative strategies to reduce existential risk.
• Field-building: we foster a global community of academics, technologists and policy-makers working to tackle existential risk.

Our last Six Month Report was in April 2019. Since then, we have continued to advance existential risk research and grow the field. Highlights include:

• Publication of two academic books by Sir Partha Dasgupta on the sixth mass extinction and on population ethics.
• Publication of seven academic papers on risks associated with AI and nuclear weapons, release norms for machine learning, mediation in climate diplomacy, avoiding polarisation around negative emission technologies, and new technologies for producing animal feed more sustainably.
• Publication of a policy report on how governments can better understand extreme risks, influencing the EU AI ethics guidelines, and engaging with leading UK and international policy-makers.
• Ellen Quigley’s appointment to advise Cambridge University on responsible investment.
• Ten expert workshops on AI risks, climate change, managing global catastrophic risks, and biosecurity.
• Raising awareness of existential risk through articles, podcasts, TV appearances, lectures and the Ground Zero Earth’ exhibition.
• Hosting our first internship scheme, with four Summer Visitors.
• Hiring five new team members, with recruitment about to begin for four more.

2. Policy Engagement – Impact:

We have had the opportunity to speak directly with policymakers and institutions across the world who are grappling with the difficult and novel challenge of how to unlock the socially beneficial aspects of new technologies while mitigating their risks. Through advice and discussions, we have the opportunity to reframe the policy debate and to hopefully shape the trajectory of these technologies themselves.

• We published a Policy Report Managing global catastrophic risks: Part 1 Understand. Its purpose is to inform policy-makers at a national level how they can better understand global catastrophic risks. We put out a press release and it received media coverage in Vox, the Irish Times, and elsewhere. We had several meetings in London, New York, Washington DC, San Francisco and Canberra to discuss the report with policy-makers.
• The EU’s AI ethics guidelines were published. It reflected advice that Haydn Belfield and Dr Shahar Avin had submitted to the High-Level Expert Group, drawing attention to the recommendations in The Malicious Use of Artificial Intelligence report. The EU’s Ethics Guidelines are likely to affect policy and corporate behaviour across Europe.
• Dr Catherine Rhodes was involved in three submissions to the UK Parliament’s Joint Committee on the National Security Strategy Inquiry on Biosecurity and Human Health: Preparing for Emerging Infectious Diseases and Bioweapons:
• Co-author of BHH0010 – Written evidence submitted by Dr Cassidy Nelson et al. This developed from an FHI roundtable.
• Lead in drafting BHH0005 – Written evidence submitted by Biosecurity Research Initiative at St Catharine’s College (BioRISC), Cambridge.
• Individual submission BHH0007 – Written evidence submitted by Dr Catherine Rhodes, Executive Director, Centre for the Study of Existential Risk ‘International Governance of Biosecurity and Human Health: Challenges and Opportunities for Coordination and Coherence’.
• The All-Party Parliamentary Group for Future Generations held two events in Parliament, continuing our engagement with MPs and Peers on long-termism:
• 11 June: Drones, Swarming and the Future of Warfare, with David Hambling, Journalist and Author of ‘Swarm Troopers’, and Sebastian Brixey-Williams, Programme Director, BASIC. Report here.
• 22 May: Negative emissions technologies: a necessary step or a false hope? with Dr Naomi Vaughn, Charlotte Morgan and Dr David Reiner. Report here.
• 21 May: CSER was a partner in the Zero Carbon Futures Symposium organised by Carbon Neutral Cambridge. This also involved participants from the Greater Cambridge Shared Planning Service, South Cambridgeshire District Council, Cambridge City Council, and local businesses. Its aim was to help accelerate the local transition to Net Zero Carbon by informing policy development for the new Greater Cambridge Local Plan. Report here.
• 21 May: Dr Catherine Rhodes and Dr Sam Weiss Evans participated in a policy roundtable on emerging technologies where there is a need for global coordination and frameworks co-organised by the Centre for Science and Policy (CSaP) and the Cabinet Office G7/G20 team.

Topics included horizon-scanning and foresight, targeting and misinformation.
• Dr Jess Whittlestone spoke at the OECD 2019 Forum on AI ethics principles.
• September: Dr Ellen Quigley participated in the United Nations Principles for Responsible Investment (PRI) conference. She has been appointed to work with Cambridge University's Chief Financial Officer to establish a ‘responsible investment’ research programme. We have hired two research assistants to support her in this work.
• CSER researchers continued meetings with top UK civil servants as part of the policy fellows program organized by CSaP.

3. Industry Engagement – Impact:

Researchers continued their extensive and deep collaboration with industry. Extending our links improves our research by exposing us to the cutting edge of industrial R&D, and helps to nudge powerful companies towards more responsible practices.

• August / September: Haydn Belfield spent a month embedding at a leading AI company in San Francisco, deepening our links and collaborating on a multistakeholder report. He also contributed to two reports on publication/release norms. Previously in San Francisco, he chaired several sessions at Effective Altruism Global San Francisco and participated in an invite-only workshop on AI and international security.
• Dr Catherine Rhodes attended the Australian Leadership Retreat, and was a speaker in the sessions ‘Climate Change and Ecological Breakdown’, ‘Leadership for Existential Threats’, and ‘Is Australia’s Sovereignty at Risk?’. The ALC is Australia’s premier forum for top-100 CEOs and national policymakers.
• Dr Sean O hEigeartaigh gave a keynote talk at the Times Higher Education Innovation Summit in Korea, and met with experts from KAIST. He also participated in several meetings and working groups of the Partnership on AI.
• Dr Shahar Avin continued running 'scenario exercises' exploring different possible AI scenarios. He has run over thirty so far, with some participants from leading AI labs. He aims to explore the realm of possibilities, and educate participants on some of the challenges ahead.

4. Academic Engagement – Field-building:

8. Publications

• Partha Dasgupta, Peter Raven and Anna McIvor (Eds.). (2019). Biological Extinction. Cambridge University Press.
• “The rapidly increasing human pressure on the biosphere is pushing biodiversity into the sixth mass extinction event in the history of life on Earth. The organisms being exterminated are integral working parts of our planet's life support system, and their loss is permanent. Like climate change, this irreversible loss has potentially devastating consequences for humanity. As we come to recognise the many ways in which we depend on nature, this can pave the way for a new ethic that acknowledges the importance of co-existence between humans and other species. Biological Extinction features chapters contributed by leading thinkers in diverse fields of knowledge and practice, including biology, economics, geology, archaeology, demography, architecture and intermediate technology. Drawing on examples from various socio-ecological systems, the book offers new perspectives on the urgent issue of biological extinction, proposing novel solutions to the problems that we face.”
• It draws upon the 2017 workshop with the Vatican’s Pontifical Academy of Sciences he co-organised.
• Partha Dasgupta. (2019). Time and the Generations - population ethics for a diminishing planet. New York: Columbia University Press),
• “How should we evaluate the ethics of procreation, especially the environmental consequences of reproductive decisions on future generations, in a resource-constrained world? While demographers, moral philosophers, and environmental scientists have separately discussed the implications of population size for sustainability, no one has attempted to synthesize the concerns and values of these approaches. Time and the Generations blends economics, philosophy, and ecology to provide tentative answers to two fundamental questions: What level of economic activity can our planet support over the long run, and what does the answer say about optimum global population numbers? Dasgupta develops a population ethics that can be used to evaluate our choices and guide our sense of a sustainable global population and living standards. Structured around a central essay from Dasgupta, the book also features a foreword from Robert Solow; correspondence with Kenneth Arrow; incisive commentaries from Joseph Stiglitz, Eric Maskin, and Scott Barrett; an extended response by the author to them; and a joint paper with Aisha Dasgupta on inequalities in reproductive decisions and the idea of reproductive rights.”

• “Increasing attention has been given in the literature to the impact of digital technologies, and in particular autonomy and machine learning, on nuclear risk. Most of this attention has focused on ‘first-order’ effects: the introduction of technologies into nuclear command-and-control and weapon-delivery systems. This essay focuses instead on higher-order effects: those that stem from the introduction of such technologies into more peripheral systems, with a more indirect (but no less real) effect on nuclear risk. It first describes and categorizes the new threats introduced by these technologies (in section I). It then considers policy responses to address these new threats (section II).”
• Asaf Tzachor. (2019). The Future of Feed: Integrating Technologies to Decouple Feed Production from Environmental Impacts. Industrial Biotechnology Vol. 15, No. 2.
• “Population growth, an expanding middle-class, and a global shift in dietary preferences have driven an enduring demand for animal products. Since animal products are playing a vital role in human diets, their consumption is predicted to increase further. However, the great dependency of animal husbandry on global staple feed crop soybean; the environmental consequences of soybean production; and barriers for soy cropland expansion cast doubt on food system sustainability. The need to mitigate future demand for soy with other feed sources of similar nutritional profile, and thereby decouple food and feed production from ecological pressures, is compelling. Yet, the literature and science of sustainable agriculture is one of incremental improvements, featuring primarily crop production intensification. A different, more profound approach to the design of feed systems is required to ensure sustainable food security. The question arises if alternative technologies exist to support such a design. This paper explores a particular novel configuration of four advanced technologies recently deployed in the region of Hengill, Iceland: light-emitting diode systems, advanced indoor photobioreactors, atmospheric carbon capture technology, and geothermal energy technology. In situ system analysis and data triangulation with scientific literature and data from independent sources illustrate the potential of these integrated technologies to produce algal-based animal feed. The analysis suggests that a highly sustainable soybean equivalent is technically attainable for feed purposes. The integrated system requires less than 1% of arable land and fresh water compared with soybean cultivation and is carbon negative. In addition, it provides a pesticide- and herbicide-free cultivation platform. This new configuration provides one pathway for the future of feed.”

• “Current conceptions of mediation can often fail to capture the complexity and intricacy of modern conflicts. This Research Handbook addresses this problem by presenting the leading expert opinions on international mediation, examining how international mediation practices, mechanisms and institutions should adapt to the changing characteristics of contemporary international crises.”
• Ovadya, A. and Jess Whittlestone. (Working Paper). Reducing malicious use of synthetic media research: considerations and potential release practices for machine learning. arXiv preprint.
• “The aim of this paper is to facilitate nuanced discussion around research norms and practices to mitigate the harmful impacts of advances in machine learning (ML). We focus particularly on the use of ML to create “synthetic media” (e.g. to generate or manipulate audio, video, images, and text), and the question of what publication and release processes around such research might look like, though many of the considerations discussed will apply to ML research more broadly. We are not arguing for any specific approach on when or how research should be distributed, but instead try to lay out some useful tools, analogies, and options for thinking about these issues.”
• Simon Beard. (2019). Book Review - Climate Justice: Integrating Economics and Philosophy. Economics and Philosophy.
• “Debates about justice are increasingly seen as vital to policy-making and international dialogue on climate change and how we should respond to it. While many disciplines have participated in these debates, philosophers and economists are often the most vocal. However, given the many historical disagreements between these disciplines this raises the question of whether we are fighting on the same team. This important volume of essays, edited by a philosopher and an economist who have contributed to both academic debates and real-world policy forums on climate change, argues that we are.”
• Haydn Belfield. (2019). How to respond to the potential malicious uses of artificial intelligence? Journal of Unsolved Questions.
• “Artificial intelligence (AI) is beginning to change our world – for better and for worse. Like any other powerful and useful technology, it can be used both to help and to harm. We explored this in a major February 2018 report The Malicious Use of Artificial Intelligence: Forecasting, Prevention, and Mitigation. We co-authored this report with 26 international experts from academia and industry to assess how criminals, terrorists and rogue states could maliciously use AI over the next five years, and how these misuses might be prevented and mitigated. In this piece I will cover recent advances in artificial intelligence, some of the new threats these pose, and what can be done about it.”

• “This paper identifies critical lessons from the climate change experience to guide how communications and engagement on negative emissions can be conducted to encourage functional public and policy discourse. Negative emissions technologies present a significant opportunity for limiting climate change, and are likely to be necessary to keep warming below 2°C. While the concept of negative emissions is still in its infancy, there is evidence of nascent polarization, and a lack of nuance in discussion of individual technologies. We argue that if negative emissions technologies are to be implemented effectively and sustainably, an effective governance regime is needed; built on functional societal discourse and avoiding the ideological baggage of the broader climate change debate or the controversies concerning geoengineering. At its core, our argument is to avoid the ideological bundling of negative emissions; this can be pursued directly and via careful selection of communication frames and the use of non-partisan, trusted messengers. Whether these lessons are heeded may determine if negative emissions are governed proactively, or are distorted politically, misused and delayed.”
