Alexei Turchin – Lifeboat News: The Blog https://lifeboat.com/blog Safeguarding Humanity Mon, 09 Sep 2019 12:42:28 +0000 en-US hourly 1 https://wordpress.org/?v=6.6.2 Russian x-risks newsletter, summer 2019 https://lifeboat.com/blog/2019/09/russian-x-risks-newsletter-summer-2019 Mon, 09 Sep 2019 12:42:28 +0000 https://lifeboat.com/blog/2019/09/russian-x-risks-newsletter-summer-2019

This is the first Russian x-risks newsletter, which will present news about Russia and global catastrophic risks from the last 3 months.

Given the combination of high technological capabilities, poor management, high risk tolerance and attempts to catch up with West and China in the military sphere, Russia is prone to technological catastrophes. It has a 10 times higher level of aviation catastrophes and car accidents than developed countries.

Thus it seems possible that a future global catastrophe may be somehow connected with Russia. However, most of the work in global catastrophic and existential risk (x-risks) prevention and policy efforts are happening in the West, especially in US, UK and Sweden. Even the best policies adopted by the governments of these countries may not help if a catastrophe occurs in another country or countries.

Http://immortality https://lifeboat.com/blog/2018/12/http-immortality Mon, 24 Dec 2018 14:22:44 +0000 https://lifeboat.com/blog/2018/12/http-immortality Ok, the new version of my global risk prevention map is up (pdf link is in comments) and now it is accompanied by recently the published article “Approaches to the Prevention of Global Catastrophic Risks.”


Abstract: Many global catastrophic and existential risks (X-risks) threaten the existence of humankind. There are also many ideas for their prevention, but the meta-problem is that these ideas are not structured. This lack of structure means it is not easy to choose the right plan(s) or to implement them in the correct order. I suggest using a “Plan A, Plan B” model, which has shown its effectiveness in planning actions in unpredictable environments. In this approach, Plan B is a backup option, implemented if Plan A fails. In the case of global risks, Plan A is intended to prevent a catastrophe and Plan B to survive it, if it is not avoided. Each plan has similar stages: analysis, planning, funding, low-level realization and high-level realization. Two variables—plans and stages—provide an effective basis for classification of all possible X-risks prevention methods in the form of a two-dimensional map, allowing the choice of optimal paths for human survival. I have created a framework for estimating the utility of various prevention methods based on their probability of success, the chances that they will be realized in time, their opportunity cost, and their risk. I also distinguish between top-down and bottom-up approaches.

CSER Special Issue: ‘Futures of Research in Catastrophic and Existential Risk’ https://lifeboat.com/blog/2018/10/cser-special-issue-futures-of-research-in-catastrophic-and-existential-risk Tue, 02 Oct 2018 19:03:21 +0000 https://lifeboat.com/blog/2018/10/cser-special-issue-futures-of-research-in-catastrophic-and-existential-risk The Centre for the Study of Existential Risk’s (CSER) special issue Futures of Research in Catastrophic and Existential Risk was recently published. CSER is an interdisciplinary research centre within the University of Cambridge dedicated to the study and mitigation of risks that could lead to human extinction or civilisational collapse.

The special issue, edited by CSER postdoc Dr Adrian Currie, brings together a wide range of research on existential and catastrophic risk. This research is increasingly multi-disciplinary and broad in scope. It considers how existential risk is conceptualized as well as challenges in communication, responsibility and epistemology. Many of the fifteen papers collected here were originally presented at our first Cambridge Conference on Catastrophic Risk in 2016.

Asteroids and comets as space weapons https://lifeboat.com/blog/2018/09/asteroids-and-comets-as-space-weapons Mon, 24 Sep 2018 13:02:26 +0000 https://lifeboat.com/blog/2018/09/asteroids-and-comets-as-space-weapons

A dual use research of concern (DURC) refers to research in the life sciences that, while intended for public benefit, could also be repurposed to cause public harm. One prominent example is that of disease and contagion research (can improve disease control, but can also be used to spread disease more effectively, either accidentally or maliciously). I will argue here that DURC can and should be applicable to any technology that has a potential dual use such as this.


Approximately 66 million years ago, a 10 km sized body struck Earth, and was likely one of the main contributors to the extinction of many species at the time. Bodies the size of 5 km or larger impact Earth on average every 20 million years (one might say we are overdue for one, but then one wouldn’t understand statistics). Asteroids 1 km or larger impact Earth every 500,000 years on average. Smaller bodies which can still do considerable local damage occur much more frequently (10 m wide bodies impact Earth on average every 10 years). It seems reasonable to say that only the first category (~5 km) pose an existential threat, however many others pose major catastrophic threats*.

Given the likelihood of an asteroid impact (I use the word asteroid instead of asteroid and/or comet from here for sake of brevity), some argue that further improving detection and deflection technology are critical. Matheny (2007) estimates that, even if asteroid extinction events are improbable, due to the loss of future human generations if one were to occur, asteroid detection/deflection research and development could save a human life-year for $2.50 (US). Asteroid impact mitigation is not thought to be the most pressing existential threat (e.g. artificial intelligence or global pandemics), and yet it already seems to have better return on investment than the best now-centric human charities (though not non-human charities – I am largely ignoring non-humans here for simplicity and sake of argument).

The purpose of this article is to explore a depressing cautionary note in the field of asteroid impact mitigation. As we improve our ability to detect and (especially) deflect asteroids with an Earth-intersecting orbit away from Earth, we also improve our ability to deflect asteroids without an Earth-intersecting orbit in to Earth. This idea was first explored by Steven Ostro and Carl Sagan, and I will summarise their argument below.

This is how the world ends: will we soon see category 6 hurricanes? https://lifeboat.com/blog/2018/09/this-is-how-the-world-ends-will-we-soon-see-category-6-hurricanes Sun, 16 Sep 2018 21:02:26 +0000 https://lifeboat.com/blog/2018/09/this-is-how-the-world-ends-will-we-soon-see-category-6-hurricanes

Not the end, but interesting… Also, note that hupercanes are possible products of some mathematical instability, where the speed start to grow almost unlimited after some threshold. Buts Cat 6 is not a hypercane, as in the hypercane winds will be 500 mph.


There is no such thing as a category 6 hurricane or tropical storm — yet. But a combination of warmer oceans and more water in the atmosphere could make the devastation of 2017 pale in comparison .

Risks for Life on Habitable Planets from Superflares of Their Host Stars https://lifeboat.com/blog/2018/08/risks-for-life-on-habitable-planets-from-superflares-of-their-host-stars Sat, 11 Aug 2018 01:37:09 +0000 https://lifeboat.com/blog/2018/08/risks-for-life-on-habitable-planets-from-superflares-of-their-host-stars We explore some of the ramifications arising from superflares on the evolutionary history of Earth, other planets in the solar system, and exoplanets. We propose that the most powerful superflares can serve as plausible drivers of extinction events, and that their periodicity corresponds to certain patterns in the terrestrial fossil diversity record. On the other hand, weaker superflares may play a positive role in enabling the origin of life through the formation of key organic compounds. Superflares could also prove to be quite detrimental to the evolution of complex life on present-day Mars and exoplanets in the habitable zone of M- and K-dwarfs. We conclude that the risk posed by superflares has not been sufficiently appreciated, and that humanity might potentially witness a superflare event in the next $\sim {10}^{3}$ years, leading to devastating economic and technological losses. In light of the many uncertainties and assumptions associated with our analysis, we recommend that these results should be viewed with due caution.

Uncertain human consequences in asteroid risk analysis and the global catastrophe threshold https://lifeboat.com/blog/2018/08/uncertain-human-consequences-in-asteroid-risk-analysis-and-the-global-catastrophe-threshold Wed, 08 Aug 2018 19:22:21 +0000 https://lifeboat.com/blog/2018/08/uncertain-human-consequences-in-asteroid-risk-analysis-and-the-global-catastrophe-threshold

By pure coincidence, the article by Seth Baum was published just 5 days after a small asteroid exploded over early warning Tule station in Greenland.


This paper studies the risk of collision between asteroids and Earth. It focuses on uncertainty in the human consequences of asteroid collisions, with emphasis on the possibility of global catastrophe to human civilization. A detailed survey of the asteroid risk literature shows that while human consequences are recognized as a major point of uncertainty, the studies focus mainly on physical and environmental dimensions of the risk. Some potential human consequences are omitted entirely, such as the possibility of asteroid explosions inadvertently causing nuclear war. Other human consequences are modeled with varying degrees of detail. Direct medical effects are relatively well-characterized, while human consequences of global environmental effects are more uncertain. The latter are evaluated mainly in terms of a global catastrophe threshold, but such a threshold is deeply uncertain and may not even exist. To handle threshold uncertainty in asteroid policy, this paper adapts the concept of policy boundaries from literature on anthropogenic global environmental change (i.e., planetary boundaries). The paper proposes policy boundaries of 100 m asteroid diameter for global environmental effects and 1 m for inadvertent nuclear war. Other policy implications include a more aggressive asteroid risk mitigation policy and measures to avoid inadvertent nuclear war. The paper argues that for rare events like large asteroid collisions, the absence of robust data means that a wide range of possible human consequences should be considered. This implies humility for risk analysis and erring on the side of caution in policy.

Mystery meteor reportedly exploded with 2.1 kilotons of force above a US military base — and the Air Force said nothing https://lifeboat.com/blog/2018/08/mystery-meteor-reportedly-exploded-with-2-1-kilotons-of-force-above-a-us-military-base-and-the-air-force-said-nothing Mon, 06 Aug 2018 20:02:21 +0000 https://lifeboat.com/blog/2018/08/mystery-meteor-reportedly-exploded-with-2-1-kilotons-of-force-above-a-us-military-base-and-the-air-force-said-nothing

Meteors could be a possible trigger of the nuclear war.


Data from NASA’s Jet Propulsion Laboratory shows a record of an object of unspecified size traveling at 24.4 kilometers per second (about 54,000 mph, or Mach 74) at 76.9 degrees north latitude, 69.0 degrees west longitude, on July 25 at 11:55 p.m. That latitude and longitude checks out as almost directly over Thule, Greenland.

[1710.05796] The Cosmological Models with Jump Discontinuities https://lifeboat.com/blog/2018/07/1710-05796-the-cosmological-models-with-jump-discontinuities Mon, 30 Jul 2018 23:02:49 +0000 https://lifeboat.com/blog/2018/07/1710-05796-the-cosmological-models-with-jump-discontinuities

Risks of sudden sigularities:


The article is dedicated to one of the most undeservedly overlooked properties of the cosmological models: the behaviour at, near and due to a jump discontinuity. It is most interesting that while the usual considerations of the cosmological dynamics deals heavily in the singularities produced by the discontinuities of the second kind (a.k.a. the essential discontinuities) of one (or more) of the physical parameters, almost no research exists to date that would turn to their natural extension/counterpart: the singularities induced by the discontinuities of the first kind (a.k.a. the jump discontinuities). It is this oversight that this article aims to amend.

The human physiological impact of global deoxygenation https://lifeboat.com/blog/2018/06/the-human-physiological-impact-of-global-deoxygenation Sat, 30 Jun 2018 23:15:17 +0000 https://lifeboat.com/blog/2018/06/the-human-physiological-impact-of-global-deoxygenation

Article (2017) about oxygen depletion. “There has been a clear decline in the volume of oxygen in Earth’s atmosphere over the past 20 years. Although the magnitude of this decrease appears small compared to the amount of oxygen in the atmosphere, it is difficult to predict how this process may evolve, due to the brevity of the collected records. A recently proposed model predicts a non-linear decay, which would result in an increasingly rapid fall-off in atmospheric oxygen concentration, with potentially devastating consequences for human health. We discuss the impact that global deoxygenation, over hundreds of generations, might have on human physiology. Exploring the changes between different native high-altitude populations provides a paradigm of how humans might tolerate worsening hypoxia over time. Using this model of atmospheric change, we predict that humans may continue to survive in an unprotected atmosphere for ~3600 years. Accordingly, without dramatic changes to the way in which we interact with our planet, humans may lose their dominance on Earth during the next few millennia.”

Human dominion over planet Earth is driving profound changes that may culminate in extinction. Loss of natural vegetation and the burning of fossil fuels are altering our atmosphere at an alarming rate [1]. Two interconnected themes have received the most attention: the accelerated rise in atmospheric carbon dioxide concentration and the escalation of global temperatures. These changes are accompanied by natural phenomena with potentially catastrophic consequences, such as increasingly unpredictable climate subsystems and rising sea levels from polar ice cap recession [2–4]. If such environmental hazards were not a sufficient threat to the survival of Earth’s 7 billion plus human inhabitants, there is yet another concerning change already underway, global deoxygenation.
