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.

El Nino and the blizzard of ’16

We kept hearing that it was the warmest winter ever, and then the blizzard came along and disproved it, right? Not exactly, according to NPR:

Scientists have been doing some forensic work to figure out what set this megastorm in motion. And they think they’ve found a trail that starts with the weather pattern called El Niño…

“A lot of climate change is actually going into the oceans,” he says.

He means the oceans are absorbing a lot of the extra heat from the atmosphere. That can alter their circulation, and where and when they release that heat back into the atmosphere.

“It’s changing the behavior of the oceans in a way that affects weather patterns around the globe,” Mann says.

“striking findings” from Pew Research Center

Pew Research Center has an interesting blog post showing some “striking findings” from their 2015 work, along with links to various surveys and analyses they did. Even if you didn’t tell me what the topics are, I would be interested in the graphics. Nice, clean time series plots, bar charts, “bump charts” – lots of bump charts, and even a pie. Their maps look good, except I don’t like the animated ones that move before you have time to look at them. They need a pause button.

You can see the striking findings on the site, but here are my top five:

  1. “For the first time since the 1940s, more immigrants from Mexico are leaving the U.S. than coming into the country.” Better move those guards to the other side of the wall! (Actually, there was a South Park episode about this as I recall…)
  2. 53% of white Americans say “Our country needs to continue making changes to give blacks equal rights with whites.” Which is not all that striking, except that it changed from 39% in March 2014 to 53% in July 2015. Unless there was some major flaw in the survey (and Pew is pretty good at surveys) that’s a big change in a short time.
  3. “People in countries with significant Muslim populations express overwhelmingly negative views of ISIS”. For example, 84% of people in the Palestinian territories disapprove.
  4. 88% of scientists think it is safe to eat genetically modified foods, versus 37% of U.S. adults. 82% of scientists think growing population will be a major problem, versus 59% of U.S. adults.
  5. 45% of the U.S. public thinks climate change is a very serious problem. But only 18% of people in China do!

Look at the pictures, they’re much better than my words.

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!

December 2015 in Review

Now it’s time to review December 2015, before we get on to reviewing 2015 as a whole.

Negative stories (-10):

  • Some car dealers are deliberately talking customers out of buying electric cars that they want, because the car dealer will make less money on oil changes. (-1)
  • Breaking news: we can’t believe everything we hear on the internet. Some of it is deliberate government and corporate propaganda, and some is “online filter bubbles” or marketing algorithms telling each of us only what we want to hear. Data used by all these algorithms is becoming more and more valuable. (-1)
  • Cyberattacks or superflares could destroy the U.S. electric grid. (-1)
  • Guns cause gut-wrenching, accidental deaths of children quite frequently in the U.S. The U.S. has a rate of violent assault 5-10 times higher than our close Anglo-American cousins, which in turn have higher rates than most of Europe and developed Asia. (-1)
  • 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 Run though, 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. (-2)
  • After more than a decade of drought, there may not be enough water to sustain both Lake Powell and Lake Mead in the U.S. desert southwest. Some are suggesting draining Lake Powell. (-1)
  • This year’s “super El Nino” might have happened with or without climate change, but climate change made it more likely. I have to admit though I enjoyed sitting on my front porch in shorts on Christmas here in Philadelphia. (-1)
  • Jeffrey Sachs makes a pretty good case that the rise of violent religious fanaticism in the Middle East is largely the CIA’s fault. (-2)

Positive stories (+13):

    • Las Vegas is planning to go all renewable by 2017, mostly centralized solar. (+1)
    • Children have a natural aptitude for learning to recognize patterns. Now all we have to do is figure out which patterns we should be teaching them to recognize. (+1)
    • Some U.S. Presidential candidates want to invest in infrastructure, which is good. A national infrastructure plan might also be good. (+1)
    • Ericcson released some technology predictions for 2016 and beyond: Artificial intelligence will start to assist us without the need for smartphone screens. Virtual reality will start to come into its own for tech support, sports, dating, and shopping. And we will start to see more sensors embedded in our homes and eventually our bodies. (+1)
    • Trends in Ecology and Evolution made some technology predictions too: “managed bees as transporters of biological control agents, artificial superintelligence, electric pulse trawling, testosterone in the aquatic environment, building artificial oceanic islands, and the incorporation of ecological civilization principles into government policies in China”. (+1)
    • A serious but treatable infection can destroy a tumor. (+1)
    • Self-driving cars could drastically reduce the amount of land required for parking in cities. There are some moves toward car-free central cities around the world. (+3)
    • 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. (+2)
    • New York City recently finished planting a million trees. (+2)

So we end the year on a positive note!

paste clever title about Christmas and climate change here

We pretty much have to check in with Eric Holthaus over at Slate on the freak Christmas heat wave.

To be clear: Global warming wasn’t primarily to blame/thank for this weekend’s ridiculously warm weather. A record-breaking El Niño has shunted the jet stream far to the north, paving the way for warm air to shatter records. The lack of snow so far—that may change later on this winter—has also helped keep things warmer: Without snow on the ground, the feeble December sun can warm things up much more efficiently. Third on the list, bumping up temperatures by perhaps a couple of degrees, is global warming. (Though, recent science suggests super-strong El Niños like this one might become more common in the coming decades.) Blaming an exceptionally warm December day entirely on global warming is just as misplaced as senators seeking to use a snowball as proof against it. Climate change made this weekend’s warmth more likely, but it wasn’t the main driving force.

the Paris agreement

There is plenty of media coverage on the Paris agreement by people more knowledgeable than me. Even though I’m not an expert, I like to skim the actual document and try to pull out a few key points myself, just like I do with the IPCC reports. I had to get all the way to page 21 to find what looks to me like the two most important provisions:

  • Holding the increase in the global average temperature to well below 2 °C above pre-industrial levels and to pursue efforts to limit the temperature increase to 1.5 °C above pre-industrial levels, recognizing that this would significantly reduce the risks and impacts of climate change

  • In order to achieve the long-term temperature goal set out in Article 2, Parties aim to reach global peaking of greenhouse gas emissions as soon as possible, recognizing that peaking will take longer for developing country Parties, and to undertake rapid reductions thereafter in accordance with best available science, so as to achieve a balance between anthropogenic emissions by sources and removals by sinks of greenhouse gases in the second half of this century, on the basis of equity, and in the context of sustainable development and efforts to eradicate poverty.

The first paragraph (sentence? nobody does a run-on sentence like the United Nations) is notable because it appears to be a commitment among most of the nations of the world to a more aggressive target than the 2 degrees C that seemed all but abandoned just recently. The second paragraph is nice because it conveys clearly that the goal is not just for emissions to stop growing. They have to be rolled back to a level where they are not actually adding to the amount of greenhouse gases in the atmosphere. It seems like that would almost certainly have to mean an end to fossil fuel burning, unless carbon is being captured on a large scale.

A more pessimistic way of looking at it though is that the “second half of this century” ends in 2099, and this wording seems like it would let things keep getting worse until then, and then let them stay at whatever bad level they are at.

I suspect that technology is likely to make fossil fuels obsolete well before 2099, and if so these targets will require no action to achieve. If we are still around in 2099, we will probably have new opportunities and problems that are well beyond our wildest imaginations now.

abandoning Lake Powell


Lake Powell is on the Colorado upstream of the Grand Canyon and Las Vegas, controlled by Glen Canyon Dam. Lake Mead is downstream of the Grand Canyon, controlled by Hoover Dam. With the decade-plus drought affecting the basin, there is actually talk of bypassing Glen Canyon Dam and just letting Lake Powell drain into Lake Mead.

One option involves filling Lake Mead first. This would allow Upper Basin water to flow past Glen Canyon Dam for storage in Lake Mead. A legal analysis published in The Water Report, issue 112, concluded that the plan doesn’t violate the Compact, because the counting point for Upper Basin water deliveries could be moved downstream, from Lees Ferry to Hoover Dam. Another option is to release water through Glen Canyon Dam’s river outlet works at 3,374-foot elevation. There’s also the option of drilling bypass tunnels — as former Reclamation Commissioner Floyd Dominy once suggested.

Upper Basin officials say that losing generation at Glen Canyon would cause a “spike” in electric power prices, raising rates by as much as 500 percent. This is highly unlikely. Glen Canyon Dam’s power may be marketed to 174 Southwestern utilities and providers, yet it contributes less than 1 percent of the total capacity of the Western power grid. There are also alternative power sources available.

If Glen Canyon Dam went offline, gas-fired power plants could instantly meet the demand at a similar cost. In fact, given Lake Powell’s recent decline, the dam has already been producing only 60 percent of its generating capacity. Yet no electricity rate “spikes” have occurred.

 

the Paris climate summit

Thomas Sterner at The Economist says that there really is a near-consensus among economists on how to reduce carbon emissions.

Economists keep on repeating: all you need is a price on carbon. This is true in one narrow sense: had there—by some (peak-oil or other) magic had there been a high price on carbon then the world economy would just adapt and we would hardly notice—just like we have “adapted” to expensive gold and titanium.

But the problems are practical and political.

The problem lies in how to design the institutions and instruments that create that high price when the market does not. Subsidies must be removed, fossil fuels taxed (or subjected to permit trade) and all countries need to agree on the details in a way that all find “fair”. In Copenhagen, people hoped for a treaty that kept warming below two degrees and an agreement that was generous in giving poor countries more of the remaining space.

One idea is for a decentralized system where individual countries each create carbon markets, then link them later.

The negative attitude to heavy UN negotiations is so strong that some welcome a more “decentralised architecture” of the climate negotiations and policymaking. Some claim we do not need an agreement. It is sufficient for each country to have an individual target and permit trading scheme and then all the permit schemes could be linked together. Linked permit markets would exhibit all the advantages to trade and circumvent the need for an international agreement.

It sounds like the strategy is to set relatively low, realistic expectations for this summit and then meet them. You can say that doing something is certainly better than doing nothing. You could also say that whatever we do will be too little, too late to solve the problem. Our deeply flawed species has failed this test and we are going to suffer the consequences.

The Bank of England on Climate Change

The Bank of England believes in climate change.

“The far-sighted amongst you are anticipating broader global impacts on property, migration and political stability, as well as food and water security.”

But he said because the cost would fall on future generations there was little impetus on the current one to fix it: “In other words, once climate change becomes a defining issue for financial stability, it may already be too late.”
