Prospects for Mars colonies

I have long been skeptical about the prospects for off-world human colonies. Given that the International Space Station is the most expensive thing we have ever built and it is entirely reliant on supplies from Earth, it would be a gigantic leap just to make a self-sustaining closed life support system. Beyond that are many other obstacles, from radiation to Mars’ reduced gravity and even interpersonal conflict.

George Dvorsky has written an article with details on many of these challenges, which also quotes Louis Friedman on the psychological and philosophical implications of extraterrestrial expansion as an unlikely prospect:

If humans can’t make it to Mars, it means we’re destined to be “a single-planet species,” he said. What’s more, it suggests extraterrestrial civilizations might be in the same boat, and that the potential for “intelligent life to spread throughout the universe is very, very gloomy,” he told Gizmodo.

“If we can’t make it to a nearby planet with an atmosphere, water, and a stable surface—which in principle suggests we could do it—then certainly we’re not going to make it much beyond that,” said Friedman. “But if we’re doomed to be a single-planet species, then we need to recognize both psychologically and technologically that we’re going to have live within the limits of Earth.”

There’s a case to the made that the principal role that Mars is now playing for humanity is as some kind of faint hope that we can wreck the Earth and still somehow survive. That’s probably not healthy on any level. Having a crazy, desperate backup plan isn’t a substitute for a credible plan that doesn’t disregard or sacrifice almost everything humanity has ever valued. Furthermore, to degrade the Earth to the point where it no longer supports people would be an act of vandalism and malice toward the rest of life so severe that it would raise grave questions about whether it would be good for any life form, including us, for people to continue to survive.

The environmental effectiveness of “green” funds

It seems like a plausible rule for climate change reduction schemes that the people running them will generally prioritize other political and economic objectives over actual emission reductions. This meshes together with other forms of wishful thinking, where we give ourselves credit for overly generous assumptions about reduced emissions, then find every possible way to cheat to reduce the stringency of the system.

The latest example:

As so often, I am reminded of Stephen Gardiner 5th and 6th propositions about climate ethics from 2011:

In the perfect moral storm, our position is not that of idealized neutral observers, but rather judges in our own case, with no one to properly hold us accountable. This makes it all too easy to slip into weak and self-serving ways of thinking, supported by a convenient apathy or ideological fervor. Moreover, the devices of such corruption are sophisticated, and often function indirectly, by infiltrating the terms of ethical and epistemic argument.

And:

Given this, we are susceptible to proposals for action that do not respond to the real problem. This provides a good explanation of what has gone wrong in the last two decades of climate policy, from Rio to Kyoto to Copenhagen. However, the form of such “shadow solutions” is likely to evolve as a the situation deteriorates. Some recent arguments for pursuing geoengineering may represent such an evolution.

It’s also reminiscent of Greta Thunberg this year:

You don’t listen to the science because you are only interested in solutions that will enable you to carry on like before. Like now. And those answers don’t exist any more. Because you did not act in time. Avoiding climate breakdown will require cathedral thinking. We must lay the foundation while we may not know exactly how to build the ceiling.

No climate policy ever works as well as in an ideal case because those implementing it always have higher, more local, and more immediate priorities than the policy’s effectiveness at controlling climate change.

When I was at the Treasury Board Secretariat, for instance, I was told that when it came to the money the government was giving to car companies to supposedly improve their environmental performance it didn’t matter to us if there were any actual environmental benefits from what they were proposing, and it was similarly outside our mandate to consider whether the companies would have done the same things without the money.

We’re not coming at this like people determined to solve a problem. Instead, we’re acting like people who are being nagged to take action on a problem which we half-recognize but mostly just want to ignore. That meshes menacingly with how the problem keeps turning out to be more alarming than we feared, and where drastic action is necessary immediately to avoid catastrophe.

Germany: more climate concern than successful action

Among other things, this reinforces my view that “awareness raising” isn’t very meaningful and certainly isn’t sufficient to keep us from wrecking the global climate:

At the European elections 48% of voters said climate change was their top concern. The Green Party came second in that election and now leads Mrs Merkel’s Christian Democratic Union (CDU) in polls. Every week “Fridays for Future” protests fill the heart of Berlin with marching schoolchildren.

…

Much of the frustration comes from Germany’s sluggish performance. In the past decade it has spent a fortune rejigging its energy system while barely reducing emissions. This embarrassment comes with a price tag; under EU rules Germany could be liable for penalties worth tens of billions should it fail to meet its 2030 target. The 2020 goal is already abandoned.

Two factors explain this. First is Germany’s ongoing dependence on coal, particularly lignite, the dirty brown sort. Thanks to hefty subsidies, renewables account for over 40% of electricity production. But Mrs Merkel’s sudden abandonment of nuclear power after a tsunami-induced meltdown at a Japanese reactor in 2011, and warped price signals that made gas-fired power uneconomical, meant that cheap coal has made up much of the rest. The last mine is due to be shuttered by 2038. Too late, say activists.

Being “aware” or even concerned about climate change doesn’t have any importance if it doesn’t change behaviour, if people continue to default to dirty forms of energy, and if people won’t tolerate costs and risks as part of decarbonization.

Open thread: the Carbon Bubble

Surprisingly, despite the importance placed on it in the University of Toronto fossil fuel divestment brief and in the divestment movement generally, I don’t have a post on the idea of the carbon bubble. If we start with the temperature targets countries have chosen as the upper limit for tolerable climate change, we can calculate that the world’s total fossil fuel reserves are much bigger than necessary to bring us to that target. Hence, if governments achieve their climate change mitigation goals, most of the world’s fossil fuels will need to be left unburned and the profits firms expect to make from them will be unrealized. Under such a scenario, fossil fuel investments will be stranded.

Back in February, The Economist explained:

Yet amid the clamour is a single, jarring truth. Demand for oil is rising and the energy industry, in America and globally, is planning multi-trillion-dollar investments to satisfy it. No firm embodies this strategy better than ExxonMobil, the giant that rivals admire and green activists love to hate. As our briefing explains, it plans to pump 25% more oil and gas in 2025 than in 2017. If the rest of the industry pursues even modest growth, the consequence for the climate could be disastrous.

ExxonMobil shows that the market cannot solve climate change by itself. Muscular government action is needed. Contrary to the fears of many Republicans (and hopes of some Democrats), that need not involve a bloated role for the state.

…

According to ExxonMobil, global oil and gas demand will rise by 13% by 2030. All of the majors, not just ExxonMobil, are expected to expand their output. Far from mothballing all their gasfields and gushers, the industry is investing in upstream projects from Texan shale to high-tech deep-water wells. Oil companies, directly and through trade groups, lobby against measures that would limit emissions. The trouble is that, according to an assessment by the IPCC, an intergovernmental climate-science body, oil and gas production needs to fall by about 20% by 2030 and by about 55% by 2050, in order to stop the Earth’s temperature rising by more than 1.5°C above its pre-industrial level.

If accepted, this argument torpedoes the idea that sticking with fossil fuels is a path to prosperity while turning away from them to fight climate change is an economic sacrifice. If we’re really going to make the transition, the people who kept investing in fossil fuels until the end will have the most to lose.

Humour and group cohesion

Andy Weir’s hard sci-fi novel The Martian has a protagonist whose sense of humour was part of why he was selected as part of a crew for a Mars mission: “They all showed signs of stress and moodiness. Mark was no exception, but the way he showed it was to crack more jokes and get everyone laughing.”

Apparently, this accords with real research on interpersonal dynamics:

Something researchers have already learned from these experiments is that certain personality characteristics are essential to helping groups work well together. A good group needs a leader, a social secretary, a storyteller and a mixture of introverts and extroverts. Intriguingly, by far the most important role seems to be that of the clown. According to Jeffrey Johnson, an anthropologist at the University of Florida who has spent years examining relations between people in Antarctic crews overwintering at the South Pole, the clown is not only funny, he is also smart and knows each member of the group well enough to defuse most of the tensions that might arise during long periods of close contact. This sounds rather like the role of a jester in a royal court. The clown also acts as a bridge between different groups of people—in Antarctica the clowns linked scientists on the base with the tradesmen who also worked there. In groups that tended to fight most or to lose coherence, Dr Johnson found, there was usually no clown.

Perhaps that helps explain the sometimes childish humour in Mike Mullane’s account of the space shuttle program?

Open thread: decarbonizing fertilizer

As noted here before, getting humanity off fossil fuels requires more than replacing our electricity generation and transport systems with climate-safe alternatives. We also need to decarbonize the process of producing food and raw materials. Since most fertilizer is made from natural gas, engineering plant-fungal symbiosis to fix atmospheric nitrogen could be a promising route forward.

radioactive decay

“In nuclear physics, double beta decay is a type of radioactive decay in which two neutrons are simultaneously transformed into two protons, or vice versa, inside an atomic nucleus. As in single beta decay, this process allows the atom to move closer to the optimal ratio of protons and neutrons. As a result of this transformation, the nucleus emits two detectable beta particles, which are electrons or positrons.”
