Combating Global Warming with Frankensulfates

I don’t quite know how to react.

Chemical & Engineering News: Latest News – Support Voiced For Geo-Engineering Research To Combat Global Warming

The call to at least consider audacious geo-engineering steps that would fill the stratosphere with globe-cooling aerosols to check global warming got louder last week. In Science, Tom M. L. Wigley of the National Center for Atmospheric Research, in Boulder, Colo., writes that reducing carbon dioxide emissions is the long-term solution to global warming but that nearer term engineering of the atmosphere might provide “additional time to address the economic and technological challenges faced by a mitigation-only approach” (DOI: 10.1126/science.1131728). Last month, Nobelist Paul J. Crutzen of the Max Planck Institute for Chemistry, in Mainz, Germany, made headlines with an essay in the journal Climatic Change calling for more research into the pros and cons of injecting sulfate-based aerosols into the stratosphere as a sunlight-reflecting, cooling foil to global warming (C&EN, Aug. 7, page 19).

The paper is still not out for public consumption, because “YOUR INSTITUTIONAL SUBSCRIPTION DOES NOT INCLUDE THIS ITEM:” (How an organization that is funded wholly by government (taxpayer) money can publish in journals that make you pay to read their contents is the subject of a different rant). Nevertheless, this modeling effort builds on Crutzen’s earlier essay which I just finished reading.

Sulfate particles reflect incoming solar radiation, reducing the amount of light incident on earth and lowering the average temperature. This has been known for years, and I am sure every aerosol scientist has thought “Well, if there was some way of putting particles in the atmosphere to reflect more light, this whole global warming thing would just go away”. But the obvious issue with this approach is that sulfates in the troposphere are nasty, they cause acid rain, haze, increased mortality, etc. Crutzen expands on this further.

The great advantage of placing reflective particles in the stratosphere is their long residence time of about 1–2 years, compared to a week in the troposphere. Thus, much less sulfur, only a few percent, would be required in the stratosphere to achieve similar cooling as the tropospheric sulfate aerosol (e.g., Dickinson, 1996; Schneider, 1996; NAS, 1992; Stern, 2005). This would make it possible to reduce air pollution near the ground, improve ecological conditions and reduce the concomitant climate warming. The main issue with the albedo modification method is whether it is environmentally safe, without significant side effects

Which I guess is the key question, let alone the practicalities of introducing and maintaining 5.3 Tg (terra grams or million metric tonnes) of sulfur in the stratosphere successfully. This is a 10% increase from the current emissions of 55 Tg/year, so I guess it is not a terribly large number. Crutzen estimates that it will cost 25-30 billion dollars per year to have a loading of 1-2 Tg (to combat the most optimistic global warming scenario), though he cites a personal communication with someone at the National Academy of Sciences in 1992. This number is bogus, how do you know what something will cost if you don’t know how you’re going to do it? Crutzen has some ideas…

Locally, the stratospheric albedo modification scheme, even when conducted at remote tropical island sites or from ships, would be a messy operation. An alternative may be to release a S-containing gas at the earth’s surface, or better from balloons, in the tropical stratosphere

In other words, speculation at this point in time. The bottom line is this, the idea is not revolutionary, heck, even I thought of this in the mid 90s when I was doing sulfate aerosol work. The mechanics of how this will be done without causing some unforeseen other major issue is the real question that will take years to answer. Meanwhile, this silly personal virtue called conservation still works, look at this graph (from an NY Times article through the Washington Monthly), if Cali can do it, so can you.

  • Canada and Climate Change Regulation – Politics as Usual

    Weasel (from wikipedia)

    *Weasel picture courtesy wikipedia

    “We need to hear more about the American position, the European position, the Chinese position” before considering the bill, McGuinty told CBC News.

    CBC

    With that rather weasely statement, Canada’s Liberal Party signalled that it will support a further delay in a vote that would set realistic limits on Canada’s Greenhouse gas emissions. I was too angry yesterday to write a decent post about it, but hey, as my partner often says, “Anger is a positive emotion”. So, here goes.

    What is it?
    Bill C-311 – The Climate Change Accountability Act. aims to set binding emission targets for greenhouse gas emissions (excluding land use, land use change and forestry) for Canada. Here’s the a short sentence from the preamble:

    this legislation is intended to ensure that Canada reduces greenhouse gas emissions to an extent similar to that required by all industrialized countries in order to prevent dangerous climate change, in accordance with the scientific evidence on the impacts of increased levels of global average surface temperature and the corresponding levels of atmospheric concentrations of greenhouse gases;

    Okay, ending a long sentence with a semi-colon, strange, but there it is, a very clear and concise statement of fact intending for Canada to set realistic targets for GHG reduction

    What are the targets?
    25% below 1990 levels by 2020, 80% below 1990 levels by 2050. This is in line with IPCC recommendations (pdf) (See page 776, thanks Climate Progress) to stabilize temperature rise to < 2°C and GHG concentrations to 450 ppm CO2 eq.
    Hansen, other prominent scientists and activists at 350.org have a more ambitious target in mind, 350 ppm. In comparison, proposed legislation by John Kerry and Barbara Boxer in the US senate would reduce GHG emissions by 20% from 1990 levels, and 80% by 2050. So, this bill proposes targets that are in line with what the world’s greatest polluter (per capita, historical) is proposing and current official consensus. There is a lot of small print in the exemptions, agriculture is a big one on the US side and land use and forestry appear to be a rather significant omission on the Canadian side.

    Bottom Line: The targets are exactly what is recommended by the IPCC, are reasonable and in line with what our biggest trading partner has proposed. They need to be strengthened in the near future, but are good for now.

    What it doesn’t do
    It does not establish a mechanism to bring about these reductions, only specifies that the government come up with scientifically sound interim targets and an emissions reduction regulatory strategy, be it emissions trading, or carbon taxes, etc. That’s fine, given Canada’s balance of powers and separation of province-federal powers, it would be best for an executive approach to regulation writing.

    History

    Bill C-311 is not new. An identical version passed the House of Commons in 2008 and was stymied by an election call. Since Canada has a bicameral legislature, the bill needed to be passed by the Canadian Senate as well and the election blocked this vote. Right now, it needs a vote to get out of committee and on the floor of the House.

    So what happened?
    Well, the NDP wanted to get the bill out for vote. The Bloc Quebecois supported them. The Conservatives, in a delaying tactic, wanted to extend the committee study period for another month, citing a “need for more expert testimony”, the Liberals agreed with them and the bill is stalled for now. Why? It is all politics.

    The Politics
    This is where the story gets interesting, and epitomizes everything that is wrong with Canada’s current political system! Canada is currently (since 2006 and 2 elections on), run by a minority Conservative government. Minority governments work very differently in Canada compared with typical parliamentary democracies such as India, Israel, etc. There are no coalitions, no alliances, especially now since the Conservative party is well to the right of every other party in Parliament. Canada has four other prominent parties, the Liberals, a centrist, business friendly party that has previously governed, the NDP, a left leaning union friendly party, the Green party, an environmental issues and good governance driven party (no seats in parliament), and the Bloc Quebecois, a regional party based in Quebec which wins seats only in Quebec.

    For the Conservative party to pass legislation, they need the support of one other party. Of course, to stymie legislation, they can use various parliamentary procedures. This is why C-311 is a private member’s bill, the government, which is vehemently opposed to any meaningful climate change mitigation regulation, would not bring something like this up for vote.

    The NDP would like to be responsible for meaningful regulation on climate change as it is in line with their stated principles and also neatly aligns with their desire to be seen as a serious opposition party, and as a party capable of governing at the federal level.

    The Liberals, well, they ran their last election on a radical restructuring of the Canadian tax system called the Green Shift. This envisaged a reduction in personal income taxes combined with the establishment of a carbon tax. The Liberals lost the election, and have been a lot more cautious about bringing up environmental issues. I happen to believe that the loss was primarily due to poor election strategy, a leader with the charisma of a freshly painted wall, and a flawed electoral system that allows for too much vote splitting, “wasted” votes and is unrepresentative. But, the media has run with the “it must be the environment” meme, and currently view any environmental legislation as a vote loser. This is in direct contradiction with polling data (pdf) that indicates the opposite to be true.

    Anyway, the Liberals appeared to be getting back into the energy game. Their dear leader Michael Ignatieff (@m_ignatieff) recently tweeted about a revolutionary new clean energy plan, which seems sensible enough and forward thinking. Also, the Liberals supported this identical bill last year, and until recently. Here’s the NDP with a collection of helpful quotes from the Liberals on C-311:

    “Parliamentarians don’t know where this country is going, as a sovereign nation state, on climate change. The really good news and the good faith behind Bill C-311 is helping to prompt a timely debate of where we’re going in advance of the important Copenhagen negotiation.” – David McGuinty, Environment Committee, June 18, 2009

    “[Bill C-311] has been reintroduced under a new MP, a bill that was put forward in the last Parliament by the leader of the NDP. As such, it really has no material changes compared to its predecessor bill.” –David McGuinty, Hansard, March 4, 2009

    “It’s very simple: we won’t be taken seriously until we are serious about the environment.” – Speech to the Vancouver Board of Trade, October 13, 2009 – MIchael Ignatieff

    Unfortunately, the price for success against the government in this half-assed minority government situation is likely an election! Opinion polls indicate that an election held today would likely result in very much the same situation as the last time around, maybe even an increased near majority for the Conservatives.

    The Conservatives (in blue) have a solid lead over the Liberals (Red) and the NDP (in orange) apparently have a 20% ceiling. In a normal parliamentary system, this would mean an alliance between the NDP and Liberals to win the election pretty handily (note that the votes would not additive, but there is a conservative vote ceiling around 40%). But as long as electoral reform is off the table, and the extremely hidebound Canadian mainstream media does nothing other than bemoan the lack of electoral participation while roundly condemning any alternative that would increase such participation, we are stuck with ths situation in which a Conservative government takes this country slowly rightward where it really does not want to be taken, given that solid majorities are against said conservative policies.

    In Conclusion
    Canada dithers again on climate change. To the core supporters of the Conservative party, this is as should be. However, for the majority of the country, for the international reputation of the country, and for the political system as a whole, this is an unacceptable delay. The Liberals win no friends by being indecisive and showing no leadership. The NDP is stuck with no amount of “responsible” opposition work giving it any traction in the polls, the political intelligentsia of Canada would not accept an NDP ascendancy. The political system does not reward cooperation. So, we remain stuck, a country of many beautiful words and very little action.

    Happy Friday!

    Feds punt on Bisphenol A

    By studiously ignoring all the subtle hormone disruption effects of bisphenol A and concentrating on easily observable neurological effects, the CERHR essentially does the industry’s bidding.

    Some risk linked to plastic chemical – Los Angeles Times

    A federal panel of scientists concluded Wednesday that an estrogen-like compound in plastic could be posing some risk to the brain development of babies and children.

    Bisphenol A, or BPA, is found in low levels in virtually every human body. A component of polycarbonate plastic, it can leach from baby bottles and other hard plastic beverage containers, food can linings and other consumer products.

    Culminating months of scientific debate, the decision by the 12 advisors of the Center for the Evaluation of Risks to Human Reproduction — part of the National Institutes of Health — is the first official, government action related to the chemical. Their recommendation will be reviewed for a federal report that could lead to regulations restricting one of the most used chemicals.

    The scientists ranked their concerns about BPA, concluding they had “some concern” about neurological and behavioral effects in fetuses, infants and children, but “minimal” or “negligible” concern about reproductive effects. The findings put the panel roughly in the middle — between the chemical industry, which has long said there is no evidence of danger to humans, and the environmental activists and scientists who say it is probably harming people.

    For a detailed look at how bisphenol research has been corrupted by industry sponsored “focused counter research” – where the goal is to show no effects and the experiment is tiled to ensure this goal, read this excellent article in the The Public Library of Science Biology Open Source Journal. Note, because it is Open Access, you can actually read it without selling a kidney! Some highlights…

    The moment we published something on bisphenol A, the chemical industry went out and hired a number of corporate laboratories to replicate our research. What was stunning about what they did,” vom Saal says with a mix of outrage and bemused disbelief, “was they hired people who had no idea how to do the work. Each of the members of these groups came to me and said, ‘We don’t know how to do this, will you teach us?’”

    More…

    The HCRA report, commissioned before Schwartz’s tenure, concluded that “the weight of the evidence for low-dose effects is very weak” [15]. Industry groups hailed the report as a comprehensive review by independent experts and quickly disseminated its findings. Yet the “comprehensive” report reviewed just 19 of 47 studies available in April 2002, and when it was published more than two years later, three panelists asked not to be listed as authors.

    What the hell, just read the whole article, especially the bit about the Harvard Center for Risk Analysis and its well documented industry shillness.

    The key to understanding bisphenol research is to realize that it is a hormone disruptor that works at low doses. At high doses, normal toxicological testing doses that is, it floods the hormone receptors and slows down the receptor pathways. So, the usual technique of testing in rats and mice at high doses and extrapolating will not work.

  • Do Voluntary Environmental Programs Work?

    Through the most excellent Environmental Valuation & Cost-Benefit News blog comes notice of a book that answers a question that’s been on my mind off and on.

    Environmental Valuation & Cost-Benefit News – Post details: Reality Check: The Nature and Performance of Voluntary Environmental Programs in the United States, Europe, and Japan

    Despite a growing theoretical literature trying to explain how and why voluntary programs might be effective, there is limited empirical evidence on their success or the situations most conducive to the approaches. Even less is known about their cost-effectiveness.

    The book’s called Reality Check (and long byline) and at $40 is too expensive for a look see! But here’s a teaser:

    The central goals of Reality Check are understanding outcomes and the relationship between outcomes and design. Most of the programs it studies have positive results, but they are small compared with business-as-usual trends and the impact of other forces–such as higher energy prices. Importantly, potential gains may be quickly exhausted as the “low-hanging fruit” is picked up by voluntary programs. By including in-depth analyses by experts from the U.S., Europe, and Japan, the book advances scholarship and provides practical information for the future design of voluntary programs to stakeholders and policymakers on all sides of the Atlantic and Pacific.

    So, the answer is no, I guess. Voluntary programs catch the bulk of changes that can be carried out easily anyway and may have been part of the company plans. They also make for good Company PR. The greater the threat of regulation and good enforcement, I guess, the more power you have to set up a good voluntary program. But if it is all carrot and no stick, who knows…

    For an example of what a voluntary program looks like, here’s Climate Wise from the EPA.

  • New Device could make internal combustion 15-20% more efficient

    Improving engine efficiency and reducing pollutant emissions are extremely important. Here, we report our fuel injection technology based on the new physics principle that proper application of electrorheology can reduce the viscosity of petroleum fuels. A small device is thus introduced just before the fuel injection for the engine, producing a strong electric field to reduce the fuel viscosity, resulting in much smaller fuel droplets in atomization. Because combustion starts at the droplet surface, smaller droplets lead to cleaner and more efficient combustion. Both laboratory tests and road tests confirm our theory and indicate that such a device improves fuel mileage significantly. The technology is expected to have broad applications, applicable to current internal combustion engines and future engines as well.

    Electrorheology Leads to Efficient Combustion.

    According to the press release, this is a very simple device. It has one small advantage over the usual snake oil, it is academic research and has been peer reviewed.

    Good stuff, hope this is an easy after market addition to any vehicle with fuel injection. However, the press release also notes that the prototype is being developed for diesel engines only, and that the research was based mainly on diesel, wonder why…

    Power to Build Border Fence Is Above U.S. Law

    Banana Republic Alert…

    Securing the nation’s borders is so important, Congress says, that Michael Chertoff, the homeland security secretary, must have the power to ignore any laws that stand in the way of building a border fence. Any laws at all.

    Last week, Mr. Chertoff issued waivers suspending more than 30 laws he said could interfere with “the expeditious construction of barriers” in Arizona, California, New Mexico and Texas. The list included laws protecting the environment, endangered species, migratory birds, the bald eagle, antiquities, farms, deserts, forests, Native American graves and religious freedom.
