A point on human extinction risk analysis.

To look at existential risk rationally requires that we maintain a cool, detached perspective. It’s somewhat hard to think of how this might be done, although watching videos of planetary destruction could actually help! As a detective needs to look at a few crime scenes before he can get experienced and move beyond being a simple gumshoe, existential risk analysts need to view simulations and thought experiments of planetary destruction before they can consider it without flinching. Because it is impossible to acquire experience of human extinction risk, as by definition no one is alive afterwards, we have to settle for simulations.

The reaction of many educated adults to extinction risk discussions reminds me of the reaction kids in my Middle School health classes had to the mention of the word “penis”: adolescent giggling. If I were to get onstage in front of a random audience and start talking about existential risk when they didn’t expect it, using words like “planetary destruction”, they’d probably start giggling, at least in their minds. Obviously, we have a way to mature as a society until we can look calmly at the prospect of our own demise. By resolving to do so yourself, you can be a part of the solution instead of the problem.

Last week a blogger for the Houston Chronicle, Eric Berger, covered my post on immortality and extinction risk, and the immaturity of most of the comments received is expected but also telling. One reader writes that we should hire Will Smith to save the world, another writes: “I don’t worry about this sort of thing, because when it happens, I’ll be dead and won’t care.” Just like how you get to see someone’s true self a little better when they’re a tad tipsy, we get to see what people really think of extinction risk analysis by their anonymous comments on a big website. When people are on the record, they aren’t likely to make pithy comments like those on the blog, but they might be thinking them, and what they say in public is likely to be a dressed-up version of these sentiments. For instance, there’s an article that appeared in The Mercury on the 22nd of April in 2003, “Disastronomer Royal: More Apocalyptic then the Pope”, which exemplifies the reaction to those who take the prospect of extinction risk seriously, referring to Martin Rees in this case. Extinction denialist articles are not hard to find on the Internet: just Google them.

Ideally, existential risk analysis should be getting hundreds of millions of dollars in funding, as the study of global warming does today. Until there are planetary immune systems in place that can respond so quickly and comprehensively that the likelihood of terminal disaster is reduced to practically nothing, existential risk mitigation should be the number one priority of the human species. And the first step is for individuals, such as yourself, to look at the prospect of human extinction in a serious way.

There are dozens of published existential risks; there are undoubtedly many more that Nick Bostrom did not think of in his paper on the subject. Ideally, the Lifeboat Foundation and other organizations would identify each of these risks and take action to combat them all, but this simply isn’t realistic. We have a finite budget and a finite number of man-hours to spend on the problem, and our resources aren’t even particularly large compared with other non-profit organizations. If Lifeboat or other organizations are going to take serious action against existential risk, we need to identify the areas where we can do the most good, even at the expense of ignoring other risks. Humans like to totally eliminate risks, but this is a cognitive bias; it does not correspond to the most effective strategy. In general, when assessing existential risks, there are a number of useful heuristics:

- Any risk which has become widely known, or an issue in contemporary politics, will probably be very hard to deal with. Thus, even if it is a legitimate risk, it may be worth putting on the back burner; there’s no point in spending millions of dollars for little gain.

- Any risk which is totally natural (could happen without human intervention), must be highly improbable, as we know we have been on this planet for a hundred thousand years without getting killed off. To estimate the probability of these risks, use Laplace’s Law of Succession.

- Risks which we cannot affect the probability of can be safely ignored. It does us little good to know that there is a 1% chance of doom next Thursday, if we can’t do anything about it.

Some specific risks which can be safely ignored:

- Particle accelerator accidents. We don’t yet know enough high-energy physics to say conclusively that a particle accelerator could never create a true vacuum, stable strangelet, or another universe-destroying particle. Luckily, we don’t have to; cosmic rays have been bombarding us for the past four billion years, with energies a million times higher than anything we can create in an accelerator. If it were possible to annihilate the planet with a high-energy particle collision, it would have happened already.

- The simulation gets shut down. The idea that “the universe is a simulation” is equally good at explaining every outcome- no matter what happens in the universe, you can concoct some reason why the simulators would engineer it. Which specific actions would make the universe safer from being shut down? We have no clue, and barring a revelation from On High, we have no way to find out. If we do try and take action to stop the universe from being shut down, it could just as easily make the risk worse.

- A long list of natural scenarios. To quote Nick Bostrom: “solar flares, supernovae, black hole explosions or mergers, gamma-ray bursts, galactic center outbursts, supervolcanos, loss of biodiversity, buildup of air pollution, gradual loss of human fertility, and various religious doomsday scenarios.” We can’t prevent most of these anyway, even if they were serious risks.

Some specific risks which should be given lower priority:

- Asteroid impact. This is a serious risk, but it still has a fairly low probability, on the order of one in 105 to 107 for something that would threaten the human species within the next century or so. Mitigation is also likely to be quite expensive compared to other risks.

- Global climate change. While this is fairly probable, the impact of it isn’t likely to be severe enough to qualify as an existential risk. The IPCC Fourth Assessement Report has concluded that it is “very likely” that there will be more heat waves and heavy rainfall events, while it is “likely” that there will be more droughts, hurricanes, and extreme high tides; these do not qualify as existential risks, or even anything particularly serious. We know from past temperature data that the Earth can warm by 6–9 C on a fairly short timescale, without causing a permanent collapse or even a mass extinction. Additionally, climate change has become a political problem, making it next to impossible to implement serious measures without a massive effort.

- Nuclear war is a special case, because although we can’t do much to prevent it, we can take action to prepare for it in case it does happen. We don’t even have to think about the best ways to prepare; there are already published, reviewed books detailing what can be done to seek safety in the event of a nuclear catastrophe. I firmly believe that every transhumanist organization should have a contingency plan in the event of nuclear war, economic depression, a conventional WWIII or another political disaster. This planet is too important to let it get blown up because the people saving it were “collateral damage”.

- Terrorism. It may be the bogeyman-of-the-decade, but terrorists are not going to deliberately destroy the Earth; terrorism is a political tool with political goals that require someone to be alive. While terrorists might do something stupid which results in an existential risk, “terrorism” isn’t a special case that we need to separately plan for; a virus, nanoreplicator or UFAI is just as deadly regardless of where it comes from.

Recently, our international spokesperson, Philippe Van Nedervelde, spoke to the deputy editor of Betterhumans, Parish Mozdzierz, on the Lifeboat Foundation, its goals and activities. Here is the first question:

Betterhumans: How did the formation of the Lifeboat Foundation come about?

Philippe Van Nedervelde: Lifeboat Foundation’s founder, Eric Klien, was shaken wide awake by 9/11. The new reality of what we call (exponentially accelerating) “Asymmetric Destructive Capability” (ADC) fully hit him: ever smaller groups of people can create ever more enormous amounts of damage. And all of this thanks to advances in technology. As a bracelet-wearing cryonicist, he knew of the potentials of nanotechnology (having attended MIT Nanotechnology Group meetings in the late 1980s), and that 9/11 was just a taste of things to come. Accordingly, the Lifeboat Foundation was incorporated within months of 9/11.

With many governments pursuing new ways to power their cities via green energy, it looks like they soon may have another option to add to their list.

While most people think of cows as a “unconverted” forms of lunch and dinner, these harmless beasts may be able to energize our communities through the smelly presents that they often leave behind.

(Globes Online) GES said that the Hefer Valley plant is the first large-scale plant of its kind in Israel, and one of the first in the world. The plant utilizes 600 tons of manure a day. The manure is sterilized, and the solid and liquid waste are then processed to produce methane, which drives the generators to make electricity.

Granite Hacarmel CEO Amiaz Sagis said, “This is unquestionably an important milestone. This facility fits in with Granite Hacarmel’s strategy to invest in infrastructures and ecology. The company is also investing resources to develop alternative energy, water treatment, and desalination.”

Ironically this whole development began when the Hefer Valley Cooperative Society was ordered to find a solution towards reducing the pollution being produced by 12,000 cows. It seems that after some head scratching, this power plant was built, allowing the community to not only reduce pollution, but find a unique way at keeping the lights on.

Although many nations would benefit from turning cow manure (or sheep, horse, camel, etc.), there probably is not enough of this stuff to both fuel our planet and make our gardens grow. However, if researchers found a way to turn “human manure” into energy, we could ultimately find a renewable energy source that can keep up with our ever growing population.

NASA’s Marshall Space Flight Center has designed a nuclear-warhead-carrying spacecraft, that would be boosted by the US agency’s proposed Ares V cargo launch vehicle, to deflect asteroids.

The Ares V launch vehicle is scheduled to first fly in 2018. It would launch 130 tons to LEO.

I welcome this study for providing a clearer analysis of the deflection options and the analyzing costs of searching for threatening asteroids.

The 8.9m (29ft)-long “Cradle” spacecraft would carry six 1,500kg (3,300lb) missile-like interceptor vehicles that would carry one 1.2MT B83 nuclear warhead each, with a total mass of 11,035kg.

99942 Apophis is a near-Earth asteroid that caused a brief period of concern in December 2004 because initial observations indicated a relatively large probability that it would strike the Earth in 2029. It is 350 meters across and weighs about 46 million tons.

The study team assessed a series of approaches that could be used to divert a NEO potentially on a collision course with Earth. Nuclear explosives, as well as non-nuclear options, were assessed.
• Nuclear standoff explosions are assessed to be 10–100 times more effective than the non-nuclear alternatives analyzed in this study. Other techniques involving the surface or subsurface use of nuclear explosives may be more efficient, but they run an increased risk of fracturing the target NEO. They also carry higher development and operations risks.
• Non-nuclear kinetic impactors are the most mature approach and could be used in some deflection/mitigation scenarios, especially for NEOs that consist of a single small, solid body.
• “Slow push” mitigation techniques are the most expensive, have the lowest level of technical readiness, and their ability to both travel to and divert a threatening NEO would be limited unless mission durations of many years to decades are possible.
• 30–80 percent of potentially hazardous NEOs are in orbits that are beyond the capability of current or planned launch systems. Therefore, planetary gravity assist swingby trajectories or on-orbit assembly of modular propulsion systems may be needed to augment launch vehicle performance, if these objects need to be deflected.


This diagram shows that the nuclear options work better and can handle asteroids up to 950 meters in size


This is a table that shows that a performance index of 1 means a method was good enough to perform a successful deflection. Less than 1 means more launches are needed.


This is a drawing of the deflection vehicle

The Lifeboat foundation has the asteroid shield program

Increasingly, tools readily available on the Internet enable independent specialists or even members of the general public to do intelligence work that used to be the monopoly of agencies like the CIA, KGB, or MI6. Playing the role of an armchair James Bond, Hans K. Kristensen, a nuclear weapons specialist at the Federation of American Scientists (FAS) in Washington, D.C., recently drew attention to images on Google Earth of Chinese sites. Kristensen believes that the pictures shed light on China’s deployment of its second-generation of nuclear weapons systems: one appears to be a new ballistic missile submarine [see above image]; others may capture the replacement of liquid-fueled rockets with solid-fuel rockets at sites in north-central China, within range of ICBM fields in southern Russia.

See also: Nuclear terrorism: the new day after from the Bulletin of Atomic Scientists. From the article:

Finally, there is the question of whether the U.S. government would behave with rational restraint. This, of course, assumes that there is a government. A terrorist nuclear attack on Washington could easily kill the president, vice president, much of Congress and the Supreme Court. But in a July 12 Washington Post op-ed, Norman Ornstein revealed that the federal government has refused to make contingency plans for its own nuclear decapitation, which means that U.S. nuclear weapons could be in the hands of small, enraged launch control teams with no clear line of authority above them. Assuming that the federal government was still there, however, we can only imagine (using the reaction to the loss of a mere two buildings on 9/11 as a metric of comparison) the public rage at the loss of a city and the intense, perhaps irresistible, pressure on the president to make someone, somewhere pay for this atrocity.

Dear Lifeboat Readers,

I am a member of the Neuroscience Scientific Advisory Board at the Lifeboat Foundation and have recently posted to the BioPreserver Program page (please read the page replicated below).

I would like to initiate a conversation about expending more effort on preserving other species and their habitats. We are all understandably concerned about humanity’s survival and the Lifeboat Foundation is a testament to the numerous technologically advanced ways we can ensure our species’ survival in the future. However, I would like to hear from others who may be concerned that in our focus on our own survival we may not be doing enough for the myriad of other species with whom we share the planet. I would argue that there is less attention paid to the survival of our species’ moral integrity than there ought to be. Would it speak well of our species if we survived while everyone else (other species) disappeared? To put it bluntly, in the future, after having escaped numerous threats to survival, will we be able to look in the mirror as a species and like what we see?

For instance, with the current rate of losses, our closest living relatives, the chimpanzees, will be extinct in the wild in 50 years. The causes are indisputably anthropogenic. If we let this happen, what will it do to the morale and the psychological fiber of our species? The question of survival is not only a question of physical and psychological survival, but also survival of our integrity.

And while efforts to preserve the DNA of threatened species are laudable and important, they should not lull us into complacency about the future for other species.

With this said, I would like to propose discussing ways that the Lifeboat Foundation can apply more of its resources and talents to ensuring that there is enough room in the lifeboat for the other “nations of species” with whom we share the planet.

I look forward to your comments and ideas. Thank you, Lori Marino

BIOPRESERVER PAGE

We are currently in the midst of the sixth great mass extinction event in our planet’s history. The die-off of species is occurring at 100 to 1000 times the natural background rate and is largely due to human activities. At the current rate of die-off 1 in 4 mammals (and numerous other animal groups) will be gone in thirty years. All life forms, and especially animals, are complex organisms that thrive in a highly intricate dynamic milieu with each other and the planet’s ecosystems and this situation may limit our ability to respond once species do meet extinction.

Therefore, we also support efforts to preserve and protect the continued existence of endangered animals before they reach the endpoint of extinction. This is a critical component to BioPreserver and an important parallel effort to The Frozen Ark Project by the University of Nottingham, Natural History Museum, Zoological Society of London, and others to collect, preserve and store the DNA and viable cells from animals in danger of extinction.

We acknowledge the probability that once species are extinct it will be more difficult to reinstate their presence in the future. Although DNA preserves the genetic template of any given species it does not preserve the way these genetic instructions unfold in the physical, social and psychological context to yield the whole animal in all of its essence. Therefore, we support the joint effort to preserve both crucial genetic material of endangered animals and their present lives and habitats.

The US-led effort to expand the military BMEWS (ballistic missile early warning radar system) to Poland and the Czech Republic provoke Russian military strategists. Putin has proposed using their already operative radar base in Azerbajian (See “Azeri radar eyed for US shield”, BBC) in exchange for information from the US system. The US/NATO proposed TMD (theater missile defense) will also integrate early warning systems for short-range missiles in southern Europe. Is the race for space awareness and the weaponization of space inevitable?

The justification for the missile shield is the potential threat of long range missiles from Iran and North Korea (See “N-Korea test fires missile”, BBC). Military experts predict that with the current progress of nuclear research and missile technology available to Iran they will pose a threat to the US in 2015. NATO and Russia co-operate in certain military matters through the Russia-Nato Council but has increasingly been in conflict over the Iranian nuclear program and the European missile shield. (See “Russia-NATO: A marriage of convenience”, RIA Novosti). Russia has also demonstrated the ineffectiveness of the missile shield by launching their RS-24 multiple missile system carrying 10 warheads (See “RS-24 Missiles to replace old systems within next few years”, Interfax).

Terrestrial radars need to be complemented by satellites to keep track of missile launches across the planet (so called “boost phase interceptors”, see “Missile defense, satellites and politics”, The Space Review) to ensure complete space awareness. The Chinese Space Agency tested an anti-satellite missile earlier this year (See “Pentagon says China’s anti-satellite test posed a threat to nations”, AP). The move towards a hot space war could be imminent. The official press release was the only information given from Chinese authorities. The secrecy surrounding space capabilities was recently challenged by French authorities when they discovered 20–30 unregistered US surveillance satellites. (See “French says ‘non’ to U.S. Disclosure of Secret Satellites”, Space.com).

The race for the control of space is threatening to destabilize established military power structures. Secrecy is not the way of solving imbalances in international relations. Space is a part of the “commons” and should be dealt with accordingly. I propose an open source approach to the space awareness problematique. There are several approaches to distributed space awareness, e.g. launching private satellites for surveillance and distribution of real-time satellite imagery in order to counter a military space race. The alternative is a UN led control organization like the IAEA.

Other organizations like the Lifeboat Foundation could also play an important role in developing a threat reduction system for the ongoing cold space war.

Vladimir Putin is acting pretty crazy these days. The latest is that he is threatening to point nuclear missiles at Europe because the US is planning to install a missile defense system in Poland. How will this make Europe less inclined to have a missile defense system..? From CNN:

Speaking to foreign reporters days before he travels to Germany for the annual summit with President Bush and the other Group of Eight leaders, Putin assailed the White House plan to place a radar system in the Czech Republic and interceptor missiles in neighboring Poland. Washington says the system is needed to counter a potential threat from Iran.

In an interview released Monday, Putin suggested that Russia may respond to the threat by aiming its nuclear weapons at Europe.

“If a part of the strategic nuclear potential of the United States appears in Europe and, in the opinion of our military specialists, will threaten us, then we will have to take appropriate steps in response. What kind of steps? We will have to have new targets in Europe,” Putin said, according to a transcript released by the Kremlin. These could be targeted with “ballistic or cruise missiles or maybe a completely new system” he said.

As a Russian-American myself, I am appalled and disappointed that Putin’s anti-Americanism has reached the point where he feels he has to threaten Europe with nuclear attack because the US is planning to install a missile defense system there. All I can do is take pleasure in the fact that Putin has stated he will step down within the year, and pray that the next person to hold his office doesn’t behave like a gangster on the world stage.

The European Commission is funding a 2-year, $312,000 study on the safety and ethical aspects of synthetic biology. From the introduction part of the site:

We will pursue our objectives by means of a fact-finding mission, contribution to the European “inaugural” Conference on Synthetic Biology in Zurich (SB 3.0), an open e-forum and an international workshop. The foreseen impact of our project will be no less than to stimulate a European debate on these issues at an early stage. Past experiences, especially in the field of GM-crops, have shown the importance of an early bio-safety and ethics debate. The community recognized this need, but up to now discussions are fragmentary. Our project aims to stimulate a European debate in a proactive way. That way we will contribute to the European synthetic biology community, supplementing genuine biosafety and bioethics aspects.

Looks like a great start on addressing a very important area of concern. For a blog post of mine that goes into a bit more detail on the issue of synthetic biology and its risks, see here.
