Balloon Juice

Come for the politics, stay for the snark.

Damn right I heard that as a threat.

Why is it so hard for them to condemn hate?

You don’t get rid of your umbrella while it’s still raining.

This blog will pay for itself.

But frankly mr. cole, I’ll be happier when you get back to telling us to go fuck ourselves.

Take hopelessness and turn it into resilience.

The frogs are rarely mistaken.

Incompetence, fear, or corruption? why not all three?

Seems like a complicated subject, have you tried yelling at it?

We need to vote them all out and restore sane Democratic government.

Israel is using food as a weapon of war. Unforgivable.

Republicans don’t lie to be believed, they lie to be repeated.

Is it irresponsible to speculate? It is irresponsible not to.

“I never thought they’d lock HIM up,” sobbed a distraught member of the Lock Her Up Party.

Can we lighten up on the doomsday scenarios?

Innocent people don’t delay justice.

Republican speaker of the house Mike Johnson is the bland and smiling face of evil.

Teach a man to fish, and he’ll sit in a boat all day drinking beer.

Russian mouthpiece, go fuck yourself.

Give the craziest people you know everything they want and hope they don’t ask for more? Great plan.

Whatever happens next week, the fight doesn’t end.

The arc of the moral universe doesn’t bend itself. it’s up to us.

Relentless negativity is not a sign that you are more realistic.

The Giant Orange Man Baby is having a bad day.

Global Warming Topics Suggested By Readers

by Cheryl Rofer|  October 11, 20184:22 pm| 52 Comments

This post is in: Climate Change Solutions, Readership Capture

FacebookTweetEmail

Y’all gave me quite an earful on global warming issues. In this post, I’m collecting them into larger categories. I won’t try to identify every contributor, and some suggestions came from more than one. If I missed your suggestion, let me know in the comments.

I am not an expert on all these topics, although I can put together creditably surveys of many of them. I am more than happy to hear from anyone who has expertise in an area and is willing to write a guest post. So far, Martin has volunteered on actions in California, Dan B on communication, and Boussinesque on ocean-related issues.

And yes, I know that the classification can be cut in different ways. I’m just trying to put things together in a way to provoke discussion and eventually start to choose topics for posts.

Climate Models

  • Where is the tipping point?
  • We have enough data now that we can move past the models into doing time series analysis and estimation. The economist time series guy who helped the climate scientists on that is Peter Phillips of Yale. (Disentangling greenhouse warming and aerosol cooling to reveal Earth’s climate sensitivity)

Electrical Generation

  • Modernization of the grid – Smart grid
  • Solar
  • Wind
  • Nuclear
  • Regulation

Transportation

  • Air travel
  • Mass transit
  • Eliminate the internal combustion engine
  • Shipping

Agriculture

  • High metabolism plants to soak up all the CO2?
  • BBC – Would you give up beef to save the planet?
  • Forestry for carbon sequestration
  • Ocean fertilization
  • Soil for carbon sequestration
  • Indoor farming
  • Livestock production

Mining

  • Fracking
  • Cement manufacture, substitution

Economy

  • Jobs created and saved
  • Economic opportunity for women
  • Fossil fuel divestment
  • Balancing economic development for poor countries against energy usage
  • Transition – natural gas as a transitional fuel
  • Occupational transitions

Governmental Actions

  • VOTE DEMOCRATIC
  • Carbon tax
  • Carbon trading
  • Importance of collective action rather than consumer choices
  • Funding for research
  • California as model (links here and here and here)
  • Establishing virtuous outcomes through regulation, positive feedback loops
  • Updates on currently proposed legislation, at the federal or state level, and why it’s important for the climate. Push to call congresspeople.
  • What we can call on our individual cities to do. What policies should we be talking to our city councilors about? What has worked well in other places? How do we help people realize that these changes can be cost effective?
  • Changing code requirements for more efficient buildings
  • Could there be an environmental equivalent of ActBlue?

Mitigation

  • Coastal infrastructure
  • Displaced persons
  • Population growth
  • Denser cities
  • Wood as construction material
  • Have one less child if you’re planning to have more.
  • Switch to a plant based diet (or mostly plant based)
  • Banning all 2-stroke engines
  • Suggestions for good climate change fighting organizations to donate to or volunteer for.
  • How to make individual changes easier, or how to get more people involved in doing them.

Communicating the Issues

  • Effective viral methods like the Parkland students, the Beto campaign, and how the annoying Avenatti gets headlines.
  • Effective storytelling
  • Fox News as a problem
  • Coastline maps projecting sea-level rise
  • Some sort of recognition and memorialization of each island as it disappears. They should not be consigned to the dustbin of history.
  • A graphic that breaks down how Americans consume energy
  • Downsides of global warming – local and regional impacts, crop yields and food, ocean acidification

Resources

  • William Nordhaus, who just won the Nobel Memorial Prize in economics
  • Weitzman and Stern
  • “Chasing Ice”
  • Reddit has a subsection titled “ELI5”. Explain Like I’m 5. (Example and example)
  • Marvel Avengers
  • Drawdown
  • Michael Coney’s novel “Rax”

    Communicating the Issues

    I didn’t follow the last discussion, but I think the most important point here (and the most difficult) is changing people’s beliefs and priorities. Getting thought leaders on board will be critical: political leaders, religious leaders, media people, and so forth.

    I took this course a couple of years ago. It specifically goes point by point through various climate change denial claims if you feel to need to bring the science into an argument that you might be having with someone:

    If it hasn’t been mentioned before:

    Skeptical Science (being skeptical about global warming skepticism) blog has excellent resources on the history, basic physics, mass and energy balance equations, math and statistics, measurement methods, and particularly good at debunking bogus claims of climate science skeptics.
    I wonder if the odd name is click bait to get laypeople who are climate science skeptics to look at it.
    Everything is presented at, I think, a high school graduate or first year undergrad level.

    https://www.skepticalscience.com/

    One of the national physics associations also has a great website, but I’ll have to go look for it.

    Why is Avenatti so disliked here? Sure, he’s egotistical and self-promoting, but you need to be to some extent in this media environment to get noticed, and he is attacking the right people and hasn’t done anything awful as far as I know.

    My game is the electric industry, what do we need to know? Market forces are driving the industry to wind, solar, and now storage. Duke Energy announced today a $500 million investment in storage over the next decade or so. A utility in my state did an all-source RFP and things like solar-storage came in way below the cost new combined cycle gas plants. The future is coming very soon. But it’s not done overnight either. Clear-headed policies could speed it up, but the D’s would have to be in control of everything in this country.

    Nuclear is simply too expensive by an order of magnitude. Georgia Power is building two nuclear units–just checked–they announced the cost was $1.1 Billion more than expected, now up to $8.4 Billion. This won’t cut it. Plus, the waste issue has never been solved.

    Companies are still working on nuclear fusion, however.

    Many of the hard problems arw in a category that could be called “disrupting carbon lock-in”
    And lock-in is actively defended and heavily funded – the fights will be political, regulatory, messaging/narratives, etc. And they will be hard.

    People are always asking “what can I personally do to combat climate change?” and right now honestly the answer is “elect Democrats.” Because the GOP isn’t gonna move on this and we can’t wait for a third party to become electable before we act. (US-specific but can extrapolate.)

    Nicholas Stern has a good non-technical survey article (just a little math and people can skip it and get the gist) on economic policy and global warming.

    Public economics as if time matters: Climate change and the dynamics of policy
    N Stern – Journal of Public Economics 162, 2018 – Elsevier
    https://www.sciencedirect.com/science/article/pii/S004727271830046X

    I can only find the journal version, so might be behind a paywall, so may need to get to a college campus to download it.

    And, I am looking for the other really good climate change blog that explains the math and science behind it. I think a lot of places emphasize the mere statistics way to much, and I am a statistical kind of person, so I would normally be prejudiced in the opposite direction. For questions like climate science, statistics only take you so far, and are in the big picture, relatively ‘mere’, or at least very far from sufficient for a good understanding.
    Anyway, I thought it was the American Physical Society, but they just have a good page on it, So it is somebody else I am thinking of.

    There was a paper by GMO (Graham Mayer Otterlink) which suggests that while carbon may be nearly solvable, other things (ocean loss of productivity, land loss of agricultural productivity)will still do massive harm to human prosperity and the environment. An interesting read. GMO is an investment company.

    @Bill Arnold:

    And lock-in is actively defended and heavily funded

    Much of the value of Exxon and Shell ( and Aramco) is based on oil reserves still in the ground, and the expectation that it is coming out at a profit.
    If that assumption goes away,and that oil is NEVER coming out, then much of the value of their stock also goes away.

    @catclub: The use of variable discount rates that are very low and can go to zero is part of what Stern is talking about, but he covers a lot more ground than that.

    A lot of CW that is taken for granted now doesn’t have much solid theoretical justification in economics. Forcing the use of discount rates suggested by observed market interest rates, and that are biased against long term projects is just one of them. You look at early literature, economists were much more open minded and even, like, inquiring, about whether, for some purposes, discount rates used for long term projects should be anything but zero. Nowadays you have pooh-bahs saying that a zero discount rate can’t ever be rational, and leads to intractable problems. I don’t think that is true. The math and rationality do not demand non-zero discount rates. And I think if you read back to beginnings of all of the economic policy planning hoo-haw, back to the 1930s through early 1960s, you get a different picture.

    Trillions of dollars. That’s a lot of power.
    The wikipedia article looks not-bad (hadn’t looked previously):
    Carbon lock-in

    Carbon lock-in refers to the self-perpetuating inertia created by large fossil fuel-based energy systems that inhibits public and private efforts to introduce alternative energy technologies. Related to the concept of technological lock-in, the concept is most used in relation to the challenge of altering the current energy infrastructure to respond to global climate change.
    The concept and term was first coined by Gregory C. Unruh in a 1999 …
    The source of carbon lock-in inertia in energy systems arises from the co-evolution of large interdependent technological networks and the social institutions and cultural practices that support and benefit from system growth. The growth of the system is fostered by increasing returns to scale.

    Wikipedia references this, which has a lot of citations. (I need to study it.)
    Understanding carbon lock-in (2000)

    This paper narrative argues that industrial economies have been locked into fossil fuel-based energy systems through a process of technological and institutional co-evolution driven by path-dependent increasing returns to scale. It is asserted that this condition, termed carbon lock-in, creates persistent market and policy failures that can inhibit the di!usion of carbon-saving technologies despite their apparent environmental and economic advantages. The notion of a Techno-Institutional Complex is introduced to capture the idea that lock-in occurs through combined interactions among technological systems and governing institutions. While carbon lock-in provides a conceptual basis for understanding macro-level barriers to the diffusion of carbon-saving technologies, it also generates questions for standard economic modeling approaches that abstract away technological and institutional evolution in their elaboration. The question of escaping carbon lock-in is left for a future paper.

    (I think this issue (trumps? No) overrides almost else. Bigotry? Yes. Getting rid of GOP until they’re forced to change their marketing? Yes. But. This. This first.)

    It’s too late to prevent further warming, although there is time (we hope) to mitigate its extent. The big expense and headache will be dealing with all the outcomes, that is, how we adapt to the many problems warming brings.

    There are some scary thresholds we don’t want to cross, and it may be too late. One, melt the permafrost, releasing all the methane locked within, a greenhouse gas much more potent than carbon dioxide. This is already underway. Two, let the ocean keep absorbing atmospheric CO2 until it becomes too acidic (from the formation of carbonic acid) to support the critters at the bottom of the food chain. Result is the collapse of ocean food webs. Three, make winters warm enough to turn mountain snowpack to rain, then your water supply will run off and not be there when you need it. Four, a lot of ecosystems will be royally screwed up.

    At the same time that we need to take unified, world-wide actions to reduce greenhouse gasses, we also need to take unified, world-wide actions to combat the white supremacy / Trump / Putin / Bannon / Miller / “us first” mentality.

    To deal with Global warming, we need to act together, for the good of everyone. All of us, together. And our nation has placed in power a group of people who don’t give a rat’s ass about the “good of everyone.”

    If one part of the world is trying to stave off a threat to us all, and another — fairly powerful, but not all-powerful — part of the world wants to build walls because they don’t care about the “threat to us all,” they only see the threat of some other people trying to get into their space, then there is no hope for unified action.

    All we can do is try to make people as safe as we can.

    Thanks. I acquired a copy, and it looks interesting, with some recent references since it is a 2018 paper.
    It has a much broader focus (macro) than the line of scholarship exemplified by Gregory C. Unruh linked above that focuses on path dependencies and lock-in and breaking/bypassing them.

    I’m struggling for an analogy here; perhaps something like this, but rendered by a talented storyteller:
    We’re on a road to hell. The maintainers of that road (who, or their children, will burn/starve/[choose their fate] along with the rest of us) have dug deep deep moats on both sides of the road, filled with piranhas and candiru, crocodiles, ebola, flesh-eating bacteria, brain-eating amoebas, etc, to discourage us from forging new paths that lead somewhere other than hell, or even to purgatory. Our job as sappers build bridges over those moats, which are also defended by active evil sappers tasked with blowing up such bridges.
    Most of these enemies think that they are Good People.

    To me, one of the bigger issues that often gets overlooked,is how large a percentage of the world’s population lives along estuaries for major rivers. Because as sea levels rise,the gradient for rivers flowing to the ocean grows less, forcing wider and wider flood patterns. Simple evaluations of sea levels and coastal elevations sometimes ignore how the impacts will reach far upstream.

    Nothing in a Nuclear reactor is “off the shelf”, it’s all custom made to mil-cert standards with extreme redundancies and safety standards.

    A radiation spill or nuclear melt down is a much bigger “deal”, with the consequences lasting for hundreds of thousands of years, than say a natural gas pipeline explosion.

    However, warming of surface waters in equatorial ocean regions will severely hit productivity in those regions. Big hit to global protein production.
    Found an interesting looking recent paper (PDF)- Declining oxygen in the global ocean and coastal waters

    Analyses of direct measurements at sites around the world indicate that oxygen-minimum zones in the open ocean have expanded by several million square kilometers and that hundreds of coastal sites now have oxygen concentrations low enough to limit the distribution and abundance of animal populations and alter the cycling of important nutrients.

    Coastal artisinal fishing is an important source of food in many parts of the world.

    Two-stroke engines are remarkably polluting in terms of hydrocarbons and other pollutants, but that doesn’t mean they put out more carbon dioxide per unit of work performed. They actually put out more power per unit of displacement than four-stroke engines. Phasing them out is an environmental issue but not particularly a global warming issue. That will change when we have enough +/- carbon-neutral power that doing work with electricity more than offsets things like transmission and charging inefficiencies.

    Sorry about that.
    I’m looking through both papers tonight; both are interesting (and spawned plenty of descendant papers). I need to understand this material better to be able to properly mentally model it. Technical advances will happen in the necessary technologies, e.g. bulk electrical storage, higher density batteries for transportation, transmission, etc. Commercialization and large scale deployment of them will be fought by entrenched interests, passively (through existing lock-in) and actively (including in the political realm).

    That’s true of Gen1/Gen2 light-water reactors. They are expensive, unsafe, dirty, and a proliferation risk. Molten salt reactors like the LiFTR have none of these problems.

    Cost: Light-water reactors have to be custom built for each location. They are huge. They cost billions of dollars. LiFTRs are small – the whole reactor portion could fit into a shipping container. They could be built on an assembly line using *one* approved design that could be used in any location. There is no need for cooling towers. They do not need to be built near a source of water.

    Safety: The design of light water reactors makes them inherently dangerous. If anything gets too out of whack, you have an unavoidable meltdown. With thorium liquid-salt reactors like the LiFTR, if anything gets too out of whack, the reaction stops and everything shuts down on its own. There is zero meltdown possibility. They are walk-away safe.

    Dirty: As we all know, the waste from light-water nuclear reactors is something we have to store for tens of thousands of years. Since transporting the stuff is problematic and storage facilities are scarce, we often end up storing waste on the same site as the plant. This is a terrible idea, in that it makes accidents so much worse, and yet it is a common practice. LiFTR waste is hot for just 300 years – and some of the waste (“fission products”) have medical, commercial, and military application.

    Proliferation: The plutonium coming out of light water reactors is perfect for making bombs. The waste coming out of LiFTRs is much harder to weaponize and there’s a lot less of it.

    There was a LiFTR in operation at Los Alamos for about a decade, but it was mothballed. Molten salt reactor technology was abandoned in the sixties in order to focus on light-water reactors, the latter of which would give us fuel for bombs. Thanks, Nixon! LiFTR research is now happening in China and India.

    @Tim in SF: all that sounds too good. So why is no nation or large multinational company deploying them?

    @beef:

    the plants are expensive to build, expensive to insure, and expensive to decommission. that’s a lot of it. also, they have to be built along ocean, lakes or major rivers and that land is expensive.

    There’s about a billion dollar regulatory hurdle to development and deployment in the US. Some US companies are working on it, like Flibe Energy. China and India are way out ahead of us.

    @Interstadial:

    today’s two strokes can be phased out not by outright banning an entire cycle of engine, but by modifying regulations in order to eliminate the under-50cc exception. that’s a hell of a lot simpler, and it allows future engines to come to market if in fact companies figure out a way to make them compliant with current standards.

    likewise, if we’re going to make them full-on illegal because they don’t meet emission standards, we should also make four-stroke engines that don’t come close to meeting today’s emissions standards illegal.

    @catclub:

    india is cutting back on reactor building, including their experimental thorium program.

    as to proliferation, thorium reactors produce a reasonable amount of protactinium which readily decays into uranium 233, which is usable in weapons.

    i guess thorium is definitely better than what we have now (especially in places like india that have lots of thorium and not a lot of uranium), but it’s not the panacea many people promise.

    @chopper: I don’t know what people have been saying about every idea in nuclear power for the past fifty years. I only know what I’ve researched myself for the past twelve years.

    We are using Gen-1 solid-fuel, light-water reactors in this country. What I’m talking about is entirely different kind of reactor – a Gen-4 molten-salt reactor. They are so different I can’t even come up with an analogy. A lawn-mower and a Prius are closer together than a Gen1 and a Gen4 reactor.

    Wind and solar have become the lowest cost ways to produce electricity. The unsubsidized global average for wind is $45/MWh and for solar it’s $40/MWh. The cost of wind and solar will continue to fall rapidly over the coming years.

    New nuclear is currently $130/MWh. Bringing the cost of nuclear down to that of wind and solar is highly unlikely. The world has been working to reduce the cost of nuclear for over a half century but the cost has only risen.

    Over the last five years global electricity generation has moved from fossil fuel to renewable energy by 0.8% a year. The planet now gets 65% of its electricity from fossil fuels.

    In order to reach 0% fossil fuels by 2050 we would need to average an annual transition from FF to RE of 2% per year. That’s about 2.5x the rate we are now moving and should not be a difficult thing to do. To reach 0% by 2040 would mean moving a bit less than 4x as fast, not at all impossible. Especially when one considers that many countries (and US states) have barely started to install wind and solar generation.

    Between now and 2050 we will have to replace almost all existing coal and gas plants. Things get old and wear out. We’re going to have to replace those plants with something. New coal would be very expensive as well as not acceptable. Wind and solar are the obvious choices. The installed cost of wind and solar are a small fraction of the cost of new coal and they have no fuel costs.

    We have the technology we need. We really do not need to invent anything new. Wind and solar are our cheapest sources of electricity. If the changeover time was not critical we could sit back and let market forces clean our grids. Over time the less expensive would push out the more expensive. But we need to find a way to accelerate the transition.

    One way it, obviously, to vote in office holders who will move things along. A revenue neutral carbon price would probably be the most effective thing a government could do. Tax the burning of carbon fuels, driving their cost higher. Utilities will move faster to less expensive renewables. Use the tax money collected to subsidize utility bills so that the cost of electricity will not be changed and the economy impacted.

    On an individual level the most important thing to do is to conserve. Install LEDs. They’ll pay for themselves very quickly. Get rid of the old beer fridge in the garage that hardly gets used. Shop for appliances that get high marks on the Energy Star ratings. Turn off stuff when you aren’t using it.

    Buy your electricity from a provider that sells only green electricity if you have the option. Even if it costs a few more bucks a month. As non-green providers lose customers to green providers they’ll clean up their acts.

    If the math works for you, install solar. Don’t assume that it’s too expensive based on some numbers from a couple years back. The cost has really dropped in many places.

    @chopper: “india is cutting back on reactor building, including their experimental thorium program.”

    The Indian thorium program that was cut was a solid fuel breeder reactor program. They developed their own THOREX reprocessing. That was cut.

    There is still Indian research on thorium molten salt reactors.

    I don’t see this topic there, and perhaps it isn’t the type that you are tracking, but there is some concern that the nutritional value of some crops may decrease with increasing CO2:
