  • Bokashi is a system that essentially pickles your compost.
  • There is an unlikely but plausible scenario where Gary Johnson, the Libertarian candidate, could become President of the United States this fall. Speaking of implausible scenarios, I learned that RIchard Nixon made a serious attempt to pass a basic income bill in 1969.
  • Here is a short video explaining the Fermi Paradox, which asks why there are no aliens. Meanwhile Russian astronomers are saying there might be aliens.

modeling the Maya collapse

This interesting study included a computer model of how drought and agricultural practices could have combined to destroy the ancient Mayan civilization.

Conceptualizing sociohydrological drought processes: The case of the Maya collapse

With population growth, increasing water demands and climate change the need to understand the current and future pathways to water security is becoming more pressing. To contribute to addressing this challenge, we examine the link between water stress and society through socio-hydrological modeling. We conceptualize the interactions between an agricultural society with its environment in a stylized way. We apply the model to the case of the ancient Maya, a population that experienced a peak during the Classic Period (AD 600-830) and then declined during the ninth century. The hypothesis that modest drought periods played a major role in the society’s collapse is explored. Simulating plausible feedbacks between water and society we show that a modest reduction in rainfall may lead to an 80% population collapse.Population density and crop sensitivity to droughts, however, may play an equally important role. The simulations indicate that construction of reservoirs results in less frequent drought impacts, but if the reservoirs run dry, drought impact may be more severe and the population drop may be larger.

  • The U.S. government’s dominant ideology of free trade and globalization may have roots in U.S. government propaganda designed to provide hidden subsidies to Japan and Korea, our Cold War allies in Asia. And resulting financial deregulation in the 1990s may have been the beginning of the end for the U.S. empire.
  • A new study says that ice melting in Antarctica could double sea level rise projections in the long term. Meanwhile, in the short term, the drought in Southeast and South Asia is getting more and more severe.
  • Robert Paxton says Trump is pretty much a fascist. Although conditions are different and he doesn’t believe everything the fascists believed. Umberto Eco once said that fascists don’t believe anything, they will say anything and then what they do once in office has nothing to do with what they said.

  • Brookings has a new report on encouraging innovation in the water sector. A lot of it is just about charging more, and it should be fairly obvious why that is politically controversial even if it is the right thing economically. But the report did have an explanation of decoupling (p. 28) which I found helpful. Decoupling is an answer to the puzzle of how a utility can support conservation without losing its revenue base.
  • The U.S. Department of Energy says the technical potential of solar panels is to supply about 39% of all energy use. And electric cars may be about to come roaring back in a big way.
  • Better management of agricultural soil might be able to play a big role in carbon sequestration.

Obama vs. Drought

Obama is worried enough about drought that he stopped whatever else he was doing and issued a presidential memorandum called Building National Capabilities for Long-Term Drought Resilience. It’s pretty vague but basically orders federal agencies to work together on resilience and support for new technologies.

Also, according the Wikipedia, the difference between an executive order and a presidential memorandum is…there is no difference. There are different kinds though. I like that there is one called a “memorandum of disapproval”. I can think of a few people I may send those to tomorrow.

Mekong drought

The El Nino drought in Southeast Asia appears to be getting worse.

While Thailand continues to block rivers feeding the Mekong and divert small volumes, Vietnam said it had recorded the lowest levels of the Mekong River since 1926.

Salinity in the Mekong Delta is a growing problem for Vietnam’s rice bowl and has been made worse by rising sea levels pushing salty water upstream.

Modelling conducted by the Mekong River Commission predicted salt intrusion on Vietnam’s main Mekong channel would reach up to 162 kilometres inland this year, which is nearing the Cambodian border.

A normal year would see salt intruding only 98 kilometres inland.

Thailand is hoping the rainy season comes in late May, but the current El Nino weather pattern has so far exceeded forecasts — meaning South-East Asia’s water resources and regional relations could be further tested.

 

February 2016 in Review

I’m going to try picking the three most frightening posts, three most hopeful posts, and three most interesting posts (that are not particularly frightening or hopeful) from February.

  • The U.S. election season certainly is getting interesting, although not really in a good way. ontheissues.org has a useful summary of where U.S. political candidates stand…what are the words I’m looking for…on the the issues. Nate Silver has an interesting online tool that lets you play around with how various demographic groups tend to vote.
  • Fire trucks don’t really have to be so big.
  • Titanium dioxide is the reason Oreo filling is so white.

drought in the Mekong basin

Here’s a Straits Times story on drought in the Mekong basin, focusing on increased pumping of river water for agriculture in Thailand.

The Mekong, which originates in the Tibetan plateau, travels for more than 4,000km through China, Myanmar, Laos, Thailand, Cambodia and Vietnam before draining into the South China Sea. It supports the world’s largest inland fishery, and is a vital source of water for agricultural communities in that area.

Yet it is also a contested resource. China’s hydroelectric dams to the north, as well as those being built in Laos, have been fingered for hampering the migration of fish and blocking the movement of nutrient-rich silt downstream.

Riverside communities suffering sudden, drastic fluctuations in water level they attribute to dam operations upstream fear Thailand’s plans will only make their lives more difficult.

So it’s fed by snowmelt in an age of climate change, then goes through several countries that are considering or in the process of building dams, then provides food and economic livelihood for a whole lot of people. It sounds like a dangerous recipe. Hopefully this year’s drought is El Nino related and will not recur for awhile.

By the way, shame on you Straits Times for using a picture of a drainage channel in Nakhon Sawan province, which is in the Chao Praya basin and nowhere near the Mekong. It doesn’t change the story but it just seems like lazy journalism, and when a journalist is lazy about one detail you happen to know about, you wonder what other details they might be lazy about that you don’t.

2015 Year in Review

I’m going to try picking the most frightening, most hopeful, and most interesting post from each month. If the most interesting is also the most frightening or most hopeful, I’ll pick the next most interesting. Then I’ll have 12 nominees in each category and I’ll try to pick the most frightening, hopeful, and interesting posts of the year.

JANUARY

Most frightening: Johan Rockstrom and company have updated their 2009 planetary boundaries work. The news is not getting any better. 4 of the 9 boundaries are not in the “safe operating space”: climate change, loss of biosphere integrity, land-system change, altered biogeochemical cycles (phosphorus and nitrogen).

Most hopeful: It is starting to seem politically possible for the U.S. to strengthen regulation of risk-taking by huge financial firms.

Most interesting: Taxi medallions have been called the “best investment in America”, but now ride-sharing services may destroy them.

FEBRUARY

Most frightening: There are some depressing new books out there about all the bad things that could happen to the world, from nuclear terrorism to pandemics. Also a “financial black hole”, a “major breakdown of the Internet”, “the underpopulation bomb”, the “death of death”, and more!

Most hopeful: A new study suggests a sudden, catastrophic climate tipping point may not be too likely.

Most interesting: Government fragmentation explains at least part of suburban sprawl and urban decline in U.S. states, with Pennsylvania among the worst.

MARCH

Most frightening: The drought in California and the U.S. Southwest is the worst ever, including one that wiped out an earlier civilization in the same spot. At least it is being taken seriously and some policies are being put in place. Meanwhile Sao Paulo, Brazil is emerging as a cautionary tale of what happens when the political and professional leadership in a major urban area fail to take drought seriously. Some people are predicting that water shortages could spark serious social unrest in developing countries.

Most hopeful: If we want to design ecosystems or just do some wildlife-friendly gardening, there is plenty of information on plants, butterflies, and pollinators out there. There is also an emerging literature on spatial habitat fragmentation and how it can be purposely designed and controlled for maximum benefit.

Most interesting (I just couldn’t choose between these):

  • Innovation in synthetic drugs is quickly outpacing the ability of regulatory agencies to adapt. (I struggled whether to put this in the negative or positive column. Drugs certainly cause suffering and social problems. But that is true of legal tobacco and alcohol, and prescription drugs, as well as illegal drugs. The policy frameworks countries have used to deal with illegal drugs in the past half century or so, most conspicuously the U.S. “war” on drugs, have led to more harm than good, and it is a good thing that governments are starting to acknowledge this and consider new policies for the changing times.)
  • Germ-line engineering is much further along than anyone imagined.” This means basically editing the DNA of egg and sperm cells at will. I put this in the positive column because it can mean huge health advances. Obviously there are risks and ethical concerns too.

APRIL

Most frightening: A group of well-known economists is concerned that the entire world has entered a period of persistently low economic growth, or “secular stagnation“.

Most hopeful: Donald Shoup, author of The High Cost of Free Parking, is retiring. That might sound bad, but his ground-breaking ideas are continuing on and actually seem to be going mainstream.

Most interesting:

  • Biotechnology may soon bring us the tools to seriously monkey with photosynthesis. (This is one of those stories where I struggle between the positive and negative columns, but clearly there is a potential upside when we will have so many mouths to feed.)
  • Peter Thiel thinks we can live forever. (positive, but do see my earlier comment about mouths to feed…)

MAY

Most frightening: We’ve hit 400 ppm carbon dioxide in the atmosphere, not just some places sometimes but pretty much everywhere, all the time.

Most hopeful: The rhetoric on renewable energy is really changing as it starts to seriously challenge fossil fuels on economic grounds. Following the Fukushima disaster, when all Japan’s nuclear reactors were shut down, the gap was made up largely with liquid natural gas and with almost no disruption of consumer service. But renewables also grew explosively. Some are suggesting Saudi Arabia is supporting lower oil prices in part to stay competitive with renewables. Wind and solar capacity are growing quickly in many parts of the world.Lester Brown says the tide has turned and renewables are now unstoppable.

Most interesting: Human chemical use to combat diseases, bugs, and weeds is causing the diseases, bugs and weeds to evolve fast.

JUNE

Most frightening: One estimate says that climate change may reduce global economic growth by 3% in 2050 and 7-8% by 2100. Climate change may also double the frequency of El Nino. The DICE model is available to look at climate-economy linkages. Dennis Meadows and Jorgen Randers describe what a coming long, slow decline might look like. Rising temperatures in the Arctic are drying things out, leading to more fires, which burns more carbon, which raises temperatures, in an accelerating feedback loop.

Most hopeful: Stock values of U.S. coal companies have collapsed.

Most interesting: According to Paul Romer, academic economics has lost its way and is bogged down in “mathiness”.

JULY

Most frightening: James Hansen is warning of much faster and greater sea level rise than current mainstream expectations.

Most hopeful: Edible Forest Gardens is a great two book set that lays out an agenda for productive and low-input ecological garden design in eastern North America. You can turn your lawn into a food forest today.

Most interesting:

AUGUST

Most frightening: Steven Hawking is worried about an artificial intelligence arms race starting “within years, not decades”.

Most hopeful: It may be possible to capture atmospheric carbon and turn it into high-strength, valuable carbon fiber. This sounds like a potential game-changer to me, because if carbon fiber were cheap it could be substituted for a lot of heavy, toxic and energy-intensive materials we use now, and open up possibilities for entirely new types of structures and vehicles.

Most interesting:

  • gene drive” technology helps make sure that genetically engineered traits are passed along to offspring.
  • Technology marches on – quantum computing is in early emergence, the “internet of things” is arriving at the “peak of inflated expectations”, big data is crashing into the “trough of disillusionment”, virtual reality is beginning its assent to the “plateau of productivity”, and speech recognition is arriving on the plateau. And super-intelligent rodents may be on the way.
  • Robotics may be on the verge of a Cambrian explosion, which will almost certainly be bad for some types of jobs, but will also bring us things like cars that avoid pedestrians and computer chips powered by sweat. I for one am excited to be alive at this moment in history.

SEPTEMBER

Most frightening: Climate may be playing a role in the current refugee crisis, and the future may hold much more of this.

Most hopeful: The right mix of variety and repetition might be the key to learning.

Most interesting: Edward Tufte does not like Infographics.

OCTOBER

Most frightening: Corrupt Russian officials appear to be selling nuclear materials in Moldova.

Most hopeful: Elephants seem to have very low rates of cancer. Maybe we could learn their secrets.

Most interesting: Stephen Hawking is worried about inequality and technological unemployment.

NOVEMBER

Most frightening: I noticed that Robert Costanza in 2014 issued an update to his seminal 1997 paper on ecosystem services. He now estimates their value at $125 trillion per year, compared to a world economy of $77 trillion per year. Each year we are using up about $4-20 trillion in value more than the Earth is able to replenish. The correct conclusion here is that we can’t live without ecosystem services any time soon with our current level of knowledge and wealth, and yet we are depleting the natural capital that produces them. We were all lucky enough to inherit an enormous trust fund of natural capital at birth, and we are spending it down like the spoiled trust fund babies we are. We are living it up, and we measure our wealth based on that lifestyle, but we don’t have a bank statement so we don’t actually know when that nest egg is going to run out.

Most hopeful: There are plenty of ways to store intermittent solar and wind power so they can provide a constant, reliable electricity source.

Most interesting: Asimov’s yeast vats are finally here. This is good because it allows us to produce food without photosynthesis, but bad because it allows us to produce food without photosynthesis.

DECEMBER

Most frightening: Cyberattacks or superflares could destroy the U.S. electric grid.

Most hopeful: We had the Paris agreement. It is possible to be cynical about this agreement but it is the best agreement we have had so far.

Most interesting: I mused about whether it is really possible the U.S. could go down a fascist path. I reviewed Robert Paxton’s five stages of fascism. I am a little worried, but some knowledgeable people say not to worry. After reading Alice Goffman’s book On the Runthough, one could conclude that a certain segment of our population is living in a fascist police state right now. There is some fairly strong evidence that financial crises have tended to favor the rise of the right wing in Europe.

DISCUSSION

Well, one thing that certainly jumps out on the technology front is biotechnology. We have a couple articles about the possibility of drastic increases in the human lifespan, and what that would mean. “Germ-line engineering”, “gene drive”, and “CRISPR” are all ways of monkeying with DNA directly, even in ways that get passed along to offspring. To produce more food, we may be able to monkey with the fundamentals of photosynthesis, and if that doesn’t work we can use genetically engineered yeast to bypass photosythesis entirely.

At the risk of copyright infringement, I am reproducing the “Gartner hype cycle” below, which was mentioned in one of the posts from August.

Gartner Hype Cycle

Gartner Hype Cycle

Government and corporate labs have been making huge advances in biotechnology in the last decade or so, so it is well beyond the “innovation trigger”. It has not yet reached the “peak of inflated expectations” where it would explode onto the commercial and media scene with a lot of fanfare. I expect that will happen. We will probably see a biotech boom, a biotech bubble, and a biotech bust similar to what we saw with the computers and the internet. And then it will quietly pervade every aspect of our daily lives similar to computers and the internet, and our children will shrug and assume it has always been that way.

Obviously there are dangers. A generation of people that refuse to die on time would be one. Bioterrorism is obviously one. Then there is the more subtle matter that as we raise the limit on the size our population and consumption level can attain, the footprint of our civilization will just grow to meet the new limit. When and how we come up against these limits, and what to do about it, is the subject of the updates to two seminal papers on these issues, by Rockstrom and Costanza. We have entered an “unsafe operating space” (Rockstrom), where we are depleting much more natural capital each year than the planet can replenish (Costanza), and there will be consequences. The Paris agreement is one hopeful sign that our civilization might be able to deal with these problems, but even if we deal with the carbon emission problem, it might be too late to prevent the worst consequences, and there are going to be “layers of limits” as the authors of Limits to Growth put it all those decades ago. If we take care of the global warming problem and figure out a way to grow food for 50 billion people, eventually we will grow to 50 billion people and have to think of something else.

So without further ado:

Most frightening: I can’t pick just one. In the relatively near term, it’s the stalling out of the world economy; the convergence of climate change, drought, and the challenge of feeding so many people; and the ongoing risks from nuclear and biological weapons.

Most hopeful: I see some hope on energy and land use issues. The Paris agreement, combined with renewable energy and energy storage breakthroughs, the potential for much more efficient use of space in cities rather than letting cars take up most of the space, are all hopeful. The possibility of making carbon fiber out of carbon emissions is a particularly intriguing one. At my personal scale, I am excited to do some sustainable gardening of native species that can feed both people and wildlife. I don’t expect my tiny garden to make a major difference in the world, but if we all had sustainable gardens, they were all connected, and we weren’t wasting so much space on roads and parking, it could start adding up to a much more sustainable land use pattern.

Most interesting: I’ve already mentioned a lot of stuff, so I will just pick something I haven’t already mentioned in the discussion above: the rise of synthetic drugs. It’s just an interesting article and makes you think about what it will mean to have advanced chemical, information, and biological technologies in the hands of the little guy, actually many, many little guys. It is a brave, new, dangerous, exciting world indeed. Happy new year!
