  • Estimating Remaining Lifetime of Humanity Abstract 1. Introduction
    Estimating remaining lifetime of humanity Yigal Gurevich [email protected] Abstract In this paper, we estimate the remaining time for human existence, applying the Doomsday argument and the Strong Self-Sampling Assumption to the reference class consisting of all members of the Homo sapiens, formulating calculations in traditional demographic terms of population and time, using the theory of parameter estimation and available paleodemographic data. The remaining lifetime estimate is found to be 170 years, and the probability of extinction in the coming year is estimated as 0.43%. 1. Introduction Modern humans, Homo sapiens, exist according to available data for at least 130,000 years [4], [5]. It is interesting, however, to estimate the time remaining for the survival of humanity. To determine this value there was proposed the so-called doomsday argument [1] - probabilistic reasoning that predicts the future of the human species, given only an estimate of the total number of humans born so far. This method was first proposed by Brandon Carter in 1983 [2]. Nick Bostrom modified the method by formulating the Strong Self-Sampling Assumption (SSSA): each observer-moment should reason as if it were randomly selected from the class of all observer-moments in its reference class. [3]. In this paper, we apply the SSSA method to the reference class consisting of all members of our species, formulating calculations in traditional demographic terms of population and time, using the parameter estimation theory and the available paleodemographic data. 1 To estimate the remaining time t we will fulfill the assumption that the observer has an equal chance to be anyone at any time.

  • Anthropic Measure of Hominid (And Other) Terrestrials. Brandon Carter Luth, Observatoire De Paris-Meudon
    Anthropic measure of hominid (and other) terrestrials. Brandon Carter LuTh, Observatoire de Paris-Meudon. Provisional draft, April 2011. Abstract. According to the (weak) anthropic principle, the a priori proba- bility per unit time of finding oneself to be a member of a particular popu- lation is proportional to the number of individuals in that population, mul- tiplied by an anthropic quotient that is normalised to unity in the ordinary (average adult) human case. This quotient might exceed unity for conceiv- able superhuman extraterrestrials, but it should presumably be smaller for our terrestrial anthropoid relations, such as chimpanzees now and our pre- Neanderthal ancestors in the past. The (ethically relevant) question of how much smaller can be addressed by invoking the anthropic finitude argument, using Bayesian reasonning, whereby it is implausible a posteriori that the total anthropic measure should greatly exceed the measure of the privileged subset to which we happen to belong, as members of a global civilisation that has (recently) entered a climactic phase with a timescale of demographic expansion and technical development short compared with a breeding gen- eration. As well as “economist’s dream” scenarios with continual growth, this finitude argument also excludes “ecologist’s dream” scenarios with long term stabilisation at some permanently sustainable level, but it it does not imply the inevitability of a sudden “doomsday” cut-off. A less catastrophic likelihood is for the population to decline gradually, after passing smoothly through a peak value that is accounted for here as roughly the information content ≈ 1010 of our genome. The finitude requirement limits not just the future but also the past, of which the most recent phase – characterised by memetic rather than genetic evolution – obeyed the Foerster law of hyperbolic population growth.

  • Apocalypse Now? Initial Lessons from the Covid-19 Pandemic for the Governance of Existential and Global Catastrophic Risks
    journal of international humanitarian legal studies 11 (2020) 295-310 brill.com/ihls Apocalypse Now? Initial Lessons from the Covid-19 Pandemic for the Governance of Existential and Global Catastrophic Risks Hin-Yan Liu, Kristian Lauta and Matthijs Maas Faculty of Law, University of Copenhagen, Copenhagen, Denmark [email protected]; [email protected]; [email protected] Abstract This paper explores the ongoing Covid-19 pandemic through the framework of exis- tential risks – a class of extreme risks that threaten the entire future of humanity. In doing so, we tease out three lessons: (1) possible reasons underlying the limits and shortfalls of international law, international institutions and other actors which Covid-19 has revealed, and what they reveal about the resilience or fragility of institu- tional frameworks in the face of existential risks; (2) using Covid-19 to test and refine our prior ‘Boring Apocalypses’ model for understanding the interplay of hazards, vul- nerabilities and exposures in facilitating a particular disaster, or magnifying its effects; and (3) to extrapolate some possible futures for existential risk scholarship and governance. Keywords Covid-19 – pandemics – existential risks – global catastrophic risks – boring apocalypses 1 Introduction: Our First ‘Brush’ with Existential Risk?

Viewpoint Most Inhumane of Weapons by Daisaku Ikeda TOKYO - I believe that most of the world’s citizens would agree that nuclear weapons should be considered inhumane. It is encouraging to see that there is now a growing, if still nascent, movement to outlaw nuclear weapons based on this premise. This was highlighted at the 2010 Review Conference of the Parties to the Treaty on the Non-Proliferation of Nuclear Weapons (NPT), whose Final Document noted a “deep concern at the catastrophic humanitarian consequences of any use of nuclear weapons” and reaffirmed “the need for all States at all times to comply with applicable international law, including international humanitarian law”.

    Phillip Stillman Two Nineteenth- Century Contributions to Climate Change Discourse: The Narra- W e a tive of Hu- t h e r man Extinction S c a and the p e g o Logic of Eco- a t 8 sys- tem Management 92 The Narrative of Human Extinction ... Consider the following passage from Oscar Wilde’s “Decay of Lying” (1891): Where, if not from the Impressionists, do we get those wonderful brown fogs that come creeping down our streets, blurring the gas-lamps and changing the houses into monstrous shadows? [...] The extraordinary change that has taken place in the climate of London during the last ten years is entirely due to a particular school of Art. [...] For what is Nature? Nature is no great mother who has borne us. She is our creation. It is in our brain that she quickens to life. Things are because we see them, and what we see, and how we see it, depends on the Arts that have influenced us.1 The speaker is Vivian, a self-consciously sophistical aesthete, and his argument is that “Nature” is the causal consequence of “Art.” Not long ago, a literary critic might have quoted such a passage with unmitigated approbation: “Things are because we see them, and what we see, and how we see it, depends on the Arts that have influenced us.” The post-structural resonance of that kind of claim is strong, and the Jamesonian tradition of treating art as a means through which ideology reproduces itself depends heavily on the conviction that between the knower and the known, there must be some determining symbolic mediation.2 Now, however, it is difficult not to hesitate over the assertion that the “extraordinary change that has taken place in the climate of London during the last ten years is entirely due to a particular school of Art.” Now we tend to take referential 1 Oscar Wilde, “The Decay of Lying,” in The claims about “Nature” very seriously, especially with regard to Artist as Critic: Critical Writings of Oscar Wilde, ed.

    FROM LONGITUDE TO ALTITUDE: INDUCEMENT PRIZE CONTESTS AS INSTRUMENTS OF PUBLIC POLICY IN SCIENCE AND TECHNOLOGY Clayton Stallbaumer* I. INTRODUCTION On a foggy October night in 1707, a fleet of Royal Navy warships ran aground on the Isles of Scilly, some twenty miles southwest of England.1 Believing themselves to be safely west of any navigational hazards, two thousand sailors discovered too late that they had fatally misjudged their position.2 Although the search for an accurate method to determine longitude had bedeviled Europe for several centuries, the “sudden loss of so many lives, so many ships, and so much honor all at once” elevated the discovery of a solution to a top national priority in England.3 In 1714, Parliament issued the Longitude Act,4 promising as much as £20,0005 for a “Practicable and Useful” method of determining longitude at sea; fifty-nine years later, clockmaker John Harrison claimed the prize.6 Nearly three centuries after the fleet’s tragic demise, another accident, also fatal but far removed from longitude’s terrestrial reach, struck a nation deeply. Just four days after its crew observed a moment’s silence in memory of the Challenger astronauts, the space shuttle Columbia disintegrated upon reentry, killing all on board.7 Although * J.D., University of Illinois College of Law, 2006; M.B.A., University of Illinois College of Business, 2006; B.A., Economics, B.A., History, Lake Forest College, 2001. 1.

  • Confronting the Threat of Nuclear Winter Seth D
    Confronting the Threat of Nuclear Winter Seth D. Baum Global Catastrophic Risk Institute http://sethbaum.com * http://gcrinstitute.org Futures 72: 69-79. This version 14 October 2015. Abstract Large-scale nuclear war sends large quantities of smoke into the stratosphere, causing severe global environmental effects including surface temperature declines and increased ultraviolet radiation. The temperature decline and the full set of environmental effects are known as nuclear winter. This paper surveys the range of actions that can confront the threat of nuclear winter, both now and in the future. Nuclear winter can be confronted by reducing the probability of nuclear war, reducing the environmental severity of nuclear winter, increasing humanity’s resilience to nuclear winter, and through indirect interventions that enhance these other interventions. While some people may be able to help more than others, many people—perhaps everyone across the world—can make a difference. Likewise, the different opportunities available to different people suggests personalized evaluations of nuclear winter, and of catastrophic threats more generally, instead of a one-size-fits-all approach. Keywords: catastrophic threats, global catastrophic risk, nuclear war, nuclear winter, risk reduction 1. Introduction The explosion of nuclear weapons causes enormous fireballs, burning everything in the vicinity. Most of the ensuing smoke rises past the clouds, into the stratosphere, where it spreads around the world and remains for a time on the order of ten to twenty years. A large enough nuclear war would send up so much smoke that the global environment would be fundamentally altered. Surface temperatures and precipitation would decline, while ultraviolet radiation increases.

    Direct Fusion Drive Rocket for Asteroid Deflection IEPC-2013-296 Presented at the 33rd International Electric Propulsion Conference, The George Washington University, Washington, D.C., USA October 6{10, 2013 Joseph B. Mueller∗ and Yosef S. Raziny and Michael A. Paluszek z and Amanda J. Knutson x and Gary Pajer { Princeton Satellite Systems, 6 Market St, Suite 926, Plainsboro, NJ, 08536, USA Samuel A. Cohenk Plasma Physics Laboratory, 100 Stellarator Road, Princeton, NJ, 08540 and Allan H. Glasser∗∗ University of Washington, Department of Aeronautics and Astronautics, Guggenheim Hall, Seattle, WA 98195 Traditional thinking presumes that planetary defense is only achievable with years of warning, so that a mission can launch in time to deflect the asteroid. However, the danger posed by hard-to-detect small meteors was dramatically demonstrated by the 20 meter Chelyabinsk meteor that exploded over Russia in 2013 with the force of 440 kilotons of TNT. A 5-MW Direct Fusion Drive (DFD) engine allows rockets to rapidly reach threaten- ing asteroids that and deflect them using clean burning deuterium-helium-3 fuel, a compact field-reversed configuration, and heated by odd-parity rotating magnetic fields. This paper presents the latest development of the DFD rocket engine based on recent simulations and experiments as well as calculations for an asteroid deflection envelope and a mission plan to deflect an Apophis-type asteroid given just one year of warning. Armed with this new defense technology, we will finally have achieved a vital capability for ensuring our planet's safety from impact threats. ∗Senior Technical Staff, [email protected].

  • Planetary Defence Activities Beyond NASA and ESA
    Planetary Defence Activities Beyond NASA and ESA Brent W. Barbee 1. Introduction The collision of a significant asteroid or comet with Earth represents a singular natural disaster for a myriad of reasons, including: its extraterrestrial origin; the fact that it is perhaps the only natural disaster that is preventable in many cases, given sufficient preparation and warning; its scope, which ranges from damaging a city to an extinction-level event; and the duality of asteroids and comets themselves---they are grave potential threats, but are also tantalising scientific clues to our ancient past and resources with which we may one day build a prosperous spacefaring future. Accordingly, the problems of developing the means to interact with asteroids and comets for purposes of defence, scientific study, exploration, and resource utilisation have grown in importance over the past several decades. Since the 1980s, more and more asteroids and comets (especially the former) have been discovered, radically changing our picture of the solar system. At the beginning of the year 1980, approximately 9,000 asteroids were known to exist. By the beginning of 2001, that number had risen to approximately 125,000 thanks to the Earth-based telescopic survey efforts of the era, particularly the emergence of modern automated telescopic search systems, pioneered by the Massachusetts Institute of Technology’s (MIT’s) LINEAR system in the mid-to-late 1990s.1 Today, in late 2019, about 840,000 asteroids have been discovered,2 with more and more being found every week, month, and year. Of those, approximately 21,400 are categorised as near-Earth asteroids (NEAs), 2,000 of which are categorised as Potentially Hazardous Asteroids (PHAs)3 and 2,749 of which are categorised as potentially accessible.4 The hazards posed to us by asteroids affect people everywhere around the world.
