Nick Bostrom and Milan M Cirkovic Introduction

The term 'global catastrophic risk' lacks a sharp definition. We use it to refer, loosely, to a risk that might have the potential to inflict serious damage to human well-being on a global scale. On this definition, an immensely diverse collection of events could constitute global catastrophes potential candidates range from volcanic eruptions to pandemic infections, nuclear accidents to worldwide tyrannies, out-of-control scientific experiments to climatic changes, and cosmic hazards to...

Martin J Rees Foreword

Wells gave a lecture at the Royal Institution in London, highlighting the risk of global disaster 'It is impossible', proclaimed the young Wells, 'to show why certain things should not utterly destroy and end the human race and story why night should not presently come down and make all our dreams and efforts vain. something from space, or pestilence, or some great disease of the atmosphere, some trailing cometary poison, some great emanation of vapour from the interior of the...

Doomsday Argument

The Doomsday Argument (DA) is an anthropic argument purporting to show that we have systematically underestimated the probability that humankind will become extinct relatively soon. Originated by the astrophysicist Brandon Carter and developed at length by the philosopher John Leslie,8 DA purports to show that we have neglected to fully take into account the indexical information residing in the fact about when in the history of the human species we exist. Leslie (1996) - in what can be...

Risks from unintended consequences

We have already encountered climate change - in the form of sudden global cooling -as a destructive modality of super-eruptions and large impacts (as well as possible consequence of large-scale nuclear war, to be discussed later). Yet it is the risk of gradual global warming brought about by greenhouse gas emissions that has most strongly captured the public imagination in recent years. Anthropogenic climate change has become the poster child of global threats. Global warming commandeers a...

Fermis paradox

Fermi's paradox also known as the 'Great Silence' problem consists in the tension between 1 naturalistic origin of life and intelligence, as well as astrophysical sizes and ages of our Galaxy and 2 the absence of extraterrestrials in the Solar System, or any other traces of extraterrestrial intelligent activities in the universe.10 In particular, the lack of macroengineering or astroengineering activities observable from interstellar distances tells us that it is not the case that life evolves...

Peter Taylor Catastrophes and insurance

This chapter explores the way financial losses associated with catastrophes can be mitigated by insurance. It covers what insurers mean by catastrophe and risk, and how computer modelling techniques have tamed the problem of quantitative estimation of many hitherto intractable extreme risks. Having assessed where these techniques work well, it explains why they can be expected to fall short in describing emerging global catastrophic risks such as threats from biotechnology. The chapter ends...
