The Ethics of Meteor and Asteroid Defense

The meteor which caused extensive damage and numerous injuries in Chelyabinsk, Russia, yesterday is an unpleasant wake up call for those of us here on Earth. We live in a cosmic shooting gallery. Not only did a 150 foot wide chunk of rock (named 2012 DA14) whiz by us and miss, but a smaller rock – estimated to be 50 feet wide – hit the atmosphere over Chelyabinsk, causing extensive damage. And in the evening (Pacific Standard Time), another meteor was spotted over the San Francisco Bay Area, but thankfully caused no damage.

The Chelyabinsk meteor and 2012 DA14 were on completely different trajectories and were therefore unrelated events.  Quite possibly the third meteor sighting was unrelated to either of the others as well. We just live in the midst of a lot of falling rocks (i.e. the solar system) and sometimes we get hit.  Not very often, thankfully, but enough to warrant concern. If 2012 DA14 had hit the Earth’s atmosphere, for example, the estimated explosion would have been in the megaton range, enough to destroy a large city.

Now, for all of the previous history of the Earth, there has not been anything to be done about threatening space rocks. They were simply a fact of life, and for most of human history they were not even understood. But now we understand them, and we also have the technological capacity – should we choose to develop it – to find and stop many of these threats.

In other words our inability to stop these kinds of dangers are now our choice.

We need to take responsibility for this choice to do nothing. If we do not find the threats and develop ways to deal with them we are now negligent. We are negligent because we know the danger and yet proceed anyway, without doing anything to lessen the danger.

I’ve said this before: morality and technology are highly related. They are highly related because technology increases power, and increased power means increased moral responsibility.  The more evil you can do, the more your moral responsibility to not do that evil.  The more good you can do, the more good you are responsible to do. Our choice to not even fully know about the potential threats, much less prepare for them, is a choice to allow evil to happen, and for that we are responsible.

But now I have a prediction. As of yesterday, Russia is going to get serious about meteor and asteroid defense. Two hits in 105 years (the other being the Tunguska Blast) and Chelyabinsk being a center of nuclear research add some context. And that means Russia is going to start probing seriously powerful technologies which have dual use as seriously dangerous weapons. And (though the Cold War is over) that is going to make the United States take notice, and perhaps respond with its own research.  And that will  result in further countries (Europe, China) and then the UN taking notice.

We can consider the geopolitical situation to have been dealt an interesting card by Mother Nature. Hopefully this card, as a warning, will result in an orderly and unified human response towards these types of extraterrestrial threats. Ideally, some type of multinational research coalition can be formed to not only find more of these threats but to also figure out ways to stop them, and then, hopefully and with great caution, develop the actual means to neutralize these threats.

This will involve exceedingly dangerous research, because any technology capable of diverting an asteroid away from the Earth will also be able to divert one towards it. But, like geoengineering, this may be a technology that, for better or for worse, we are simply forced into. At this point in history, to not pursue asteroid defense is irrational because it takes a risk that simply ought not be taken: the risk that at any time, anywhere on Earth, millions – or worse -  could die from a potentially preventable disaster.

“Why a Four Degree Celsius Warmer World Must Be Avoided” Infographic

The World Bank (not known for its bleeding-heart environmental activism) has issued a new report on global warming entitled “Turn Down the Heat: Why a 4 Degree C Warmer World Must Be Avoided.”

Why should we avoid it? Because it would be verging on apocalyptic. Coral reefs dead, rainforests dead, sections of the tropics becoming uninhabitable due to heat, spreading deserts, ice sheets collapsing, rising sea levels inundating cities and entire countries… The infographic below tries to be optimistic, but it is best to know the truth: we are currently a ship of fools sailing for planetary-scale disaster. So much for tending God’s garden (this will be the second time we’ve lost that job!).

Politically there is no will  (at least in the USA and other major CO2 emitters) to fix the problem. As I have said before, I think we are being forced into the geoengineering option, because the technical solution, no matter how crazy it is, is not as difficult as the moral-political solution.

In any case, enjoy the graphic, and check out the others at the Visual.ly environment section.

Cloud Atlas by David Mitchell: A Philosophical and Ethical Book Review

Cloud Atlas by David Mitchell is a spectacular novel. It is a tour-de-force through six stories, each story with its own genre, creating a multigenre whole unlike any work I’ve read before. (There may be other works out there like this, but I don’t know them – I’m an ethicist, not a lit guy – so if you have suggested readings, let me know!)

I picked up this book because I saw the trailer for the movie version by the Wachowskis (of “The Matrix” fame) that is coming out today. I could tell that the story was going to be fascinatingly intricate, and that a movie could not do it justice, so I wanted to read the novel first before seeing the movie. I won’t include the trailer here because it may affect your reading of the story; it did for me (while reading I kept thinking “I wonder who is going to play this character?”). I will review the movie in a few days and include the trailer then.

In this review I am going to try to avoid specific spoilers, however, the generalities of the work will come up and especially what I see as the moral and philosophical core of the work. If you read this review it may spoil the novel for you on that level, so if that concerns you, just go read the book instead, then come back.

But if you want to know anyway, come along. Here’s how we will go: 1) The story itself, its style and composition, 2) Its major themes, 3) Its similarities and differences with a few other works, and a few allusions I picked up, 4) Its movie potential.

Geoengineering Goes Rogue

It was only a matter of time, but I had no idea it would be this soon. Geoengineering has gone rogue.

An environmental entrepreneur whose plan to dump iron in a patch of the Pacific Ocean was shelved four years ago after a scientific outcry has gone ahead with a similar experiment without any academic or government oversight, startling and unnerving marine researchers.

My first reaction is “environmental entrepreneur”? And my second one is “wow, this is a completely new thing.” Never in human history has a small group of humans intentionally tried to manipulate the atmosphere, much less without any kind of oversight. A true ethical novum. Brought to us by our own scientific-technological power. The New York Times continues:

The entrepreneur, Russ George, said his team scattered 100 tons of iron dust in mid-July in the Pacific several hundred miles west of the islands of Haida Gwaii, in northern British Columbia, in a $2.5 million project financed by a native Canadian group.

The substance acted as a fertilizer, Mr. George said, fostering the growth of enormous amounts of plankton that were monitored by the team for several months. He said the result could help the project meet what it casts as its top goal: aiding the recovery of the salmon fishery for the native Haida people.

But marine scientists and other experts said the experiment, which they learned about only in news reports this week, was shoddy science, irresponsible and probably in violation of international agreements intended to prevent tampering with ocean ecosystems under the guise of trying to fight the effects of climate change.

While the environmental impact of Mr. George’s foray could well prove minimal, they said, it raises the specter of what they have long feared: rogue field experiments that could upend ecosystems one day put the planet at risk. Mark L. Wells, a marine scientist at the University of Maine, said that what Mr. George’s team did “could be described as ocean dumping.”

I have discussed geoengineering and the hubristic dangers that accompany it before, arguing that it might seem logical and yet still be, perhaps, a very bad choice. I really do have mixed feelings on it. But what I can say with certainty is that anybody just going out and deciding to do it on their own must be stopped and held responsible for some type of violation.  This is an issue concerning the common good, not just of all humanity, but for the entire ecosphere. We can’t just have individuals going out there and doing giant experiments with no supervision or legitimate authorization (even if this is, in fact, what we have already accidentally done with fossil fuels, chlorofluorocarbons, and so on – this is not a road to continue on).

This is a fascinating test case, and luckily, a rather minor one. Iron dumping for plankton fertilizer is a relatively small thing compared to, say, spewing tons of sulfur dioxide into the atmosphere to reflect sunlight and cool the earth. But now that the threshold has been crossed, we can expect to see more of this, and perhaps states “going rogue” in major ways, and not just one guy and his friends.

Strange times we live in.

Is Geoengineering Now Inevitable? Or, Is the Only Solution to a Technological Problem More Technology?

Scaling the Heights of the Scala Naturae (Wikipedia)

Once a year I teach a course at Santa Clara University called “Energy, Climate Change, and Social Justice.” I love teaching it. The premise is to help engineering graduate students learn how to think ethically about the problems generated by global warming, with an eye towards coming up with innovative solutions. We look at conventional and renewable energy sources, vulnerabilities that different areas and people’s of the world face due to global warming, and potential policy solutions to help get the world on track towards carbon neutrality or negativity.

But this year a strange thought continually crossed my mind as I was teaching the course. Is active human control over the climate now inevitable?  A few months ago a friend of mine at another university had expressed to me the wish that humans would not be responsible for the Earth’s environment – not responsible for the climate, not responsible for the weather, not responsible for the deaths and destruction and rising oceans. To him it seemed much better that such events were not blameworthy, that things could just happen and they would not be anyone’s fault. The idea of filing a lawsuit over climate change just seemed very wrong. Shouldn’t there just be some things that no-one is responsible and guilty for? Would that not be a better world?

I was unsure how to respond, but the question remained on my mind. I agree that a world where humans were not responsible for the climate might be a better world, but I’m not sure we can ever go back. Here is my thinking.

SpaceX did it. Off the Earth, up to the ISS, and back again. The era of private spaceflight is really here. And what is SpaceX’s long range goal? Elon Musk wants to go to Mars. Not just his company – him, personally. And, while he’s at it, he’s going to save the world.

If you haven’t heard of Planetary Resources, you should. They’ve got billionaire backing. And they want to gobble up asteroids for their platinum. (Well, and their other elements too.) Between these guys and SpaceX, exploration is actually becoming really interesting again. And why should Christians or ethicists care? (go here to find out) Because, in the words of Alfred North Whitehead “Without adventure, civilization is in full decay.” And I think these folks are proving that we are not nearly dead yet.

Now, from air to water, literally. For areas with fresh water shortage this is brilliant: a wind turbine that condenses water from the air.  It would be perfect for the Marshall Islands, where is is windy, humid, and fresh water is unreliable. And if you were an ancient Greek, this could count as elemental transmutation.

And how about a new kind (not just a new use) of wind power while we are at it?

Yes, Chinese medicine can be dangerous.  Lots of medicines can be dangerous. The early chemist and pharmacist Paracelsus (real name: Philippus Aureolus Theophrastus Bombastus von Hohenheim – you can see why he went by Paracelsus) is noted for his phrase “the dosage makes the poison.” But seeing as many forms of Chinese medicine have never actually been scientifically tested to see what they do – in any dosage – taking them can be especially dangerous.

What Kind of a World for Our Children?

My father is a quiet man. Very smart, but not exactly philosophical. I once asked him if he had any wisdom to share with me after his long life and he said (in sum) “no.”

Which is why something he said to me many years before strikes me as all the more important. He said “I don’t think we’re leaving you a world as good as the one we were given.”

When you are a little kid that doesn’t really make sense. The world changes? The world gets better and worse? Why is it worse now? What happened to make it worse?

Now that I’m an adult it unfortunately makes perfect sense.
