Excellent Editorial on CO2 mitigation

It is nice to get away into the mountains for a while and not think about work, or climate change, but, reality drags you back. This is a great primer on various CO2 mitigation strategies, explaining in plain language, carbon taxes, cap and trade systems and such. It does tilt heavily towards the carbon tax approach, but that’s fine, I like it better than cap and trade anyway!

Time to tax carbon – Los Angeles Times

The proposed fixes for climate change are as numerous as its causes. Most only tinker at the edges of the problem, such as a California bill to phase out energy-inefficient lightbulbs. To produce the cuts in greenhouse gases needed to slow or stop global warming, the world will have to phase out the fossil fuels on which it relies for most of its power supply and transportation — especially the coal-burning power plants that account for about 32% of the annual emissions of carbon dioxide in the U.S. and that generate about half of our electricity. There are three basic methods of doing that, which are the subject of debate and legislation at every level of government.

    Flood risks from global warming underestimated.

    As CO2 levels in the atmosphere increase, plants uptake less water from the soil. Betts’ model indicates that there could be a 6 percentage point increase due to this effect on top of the 11% increase in global water flows due to direct climate effects.

    BBC NEWS | Science/Nature | Climate flooding risk ‘misjudged’

    Researchers say efforts to calculate flooding risk from climate change do not take into account the effect carbon dioxide (CO2) has on vegetation. Higher atmospheric levels of this greenhouse gas reduce the ability of plants to suck water out of the ground and “breathe” out the excess. Plants expel excess water through tiny pores, or stomata, in their leaves. Their reduced ability to release water back into the atmosphere will result in the ground becoming saturated.

    Feedbacks, always a problem and hard to predict.

  • Plastic Bag Use – Money Talks

    In 2002, Ireland passed a tax on plastic bags; customers who want them must now pay 33 cents per bag at the register. There was an advertising awareness campaign. And then something happened that was bigger than the sum of these parts.Within weeks, plastic bag use dropped 94 percent. Within a year, nearly everyone had bought reusable cloth bags, keeping them in offices and in the backs of cars. Plastic bags were not outlawed, but carrying them became socially unacceptable — on a par with wearing a fur coat or not cleaning up after one’s dog.

    Motivated by a Tax, Irish Spurn Plastic Bags – New York Times

    Turns out that you can swiftly alter habits, attitudes, perception and behavior by charging people 33 cents per bag! Plastic bags are a convenience only because they are free.

    Also, if you read the entire article, you will realize that ad-hoc, voluntary, or piecemeal approaches by individual retailers, cities or states will not make as much of an impact as a national policy.

    All hail Ireland!

  • Better Place electric car experiment not in good place

    You may have heard of Shai Agassi and Better Place (link’s to a TED talk, so you know he was important!), the car company that was going to revolutionize electric cars by separating the battery infrastructure from the car and setting up a number of battery swap stations. The goal was to remove “range anxiety” as batteries could be swapped out in 5 minutes or less. Their first experiment was in Israel and it appears to have not worked.

    Why a Promising Electric Car Startup Failed – Yale E News

    But such rosy projections never came close to materializing. One of the unexpected things to go wrong was that the company didn’t get much help from Israel. Although Shimon Peres, the former Israeli president, was an enthusiastic Better Place supporter, Israel — unlike the U.S. — provides no subsidies to EVs. Local authorities, whose permission was needed to build battery-switching stations, put up unexpected roadblocks

    Not surprised one bit. System change requires institutional support.The status quo bias in favour of the current infrastructure is massive. Gasoline cars work well for people who drive cars, regardless of the expense, which is incremental, hence easily disregarded, or pollution concerns, which are unseen and to which people only have shallow affinities for. People don’t like uncertainty or novelty in routine. If we want to produce less pollution in travel, electric cars cannot just be plugged in to the current infrastructure. This quote from David Roberts of the Grist explains it well:

    Lurking in the background is the notion that the “promise of electric cars” is false until an electric car can plop down in America’s current transportation system and do everything an internal-combustion-engine car can do. <snip> The problem, however, is not merely that our cars consume too much oil. It’s that our transportation system consumes too much oil. A better system won’t merely involve better cars, it will involve driving less, telecommuting more, using more public transportation, sharing cars, making cars smarter, and building more and better electrical infrastructure.

    betterplace

    The current infrastructure was built with sustained government support over decades and is propped up by trillions of dollars in taxes, subsidies to fossil fuel industry and such. It works for the people using it, if not for life on this planet in the long term. If I was driving, if my commute is 20 minutes, an electric car will still only take 20 minutes. If you’re stuck in traffic in a hellish commute, an electric car doesn’t help you at all. An electric car would save some money in the long run, but  no individual or market is going to build me a charging station in my apartment or workplace, or set up a range of battery swappers from scratch. 

    Building a sustainable infrastructure is not something a market can do, or is designed to do. It will be up to us to visualize where we want to go, and spend the money, time and effort needed to make it happen. We are also up against a large and well established system that does not really want this change to happen, and has spent decades eroding trust in the institutions that would have to make this change happen.

    Looking forward

    What needs to happen for electric cars to be a small part of the solution? The larger part involves system change to reduce daily transport needs, de-emphasize private transport and encourage bike, bus train and walk. For cars to be a part of the solution:

    1. Governments/communities will need to build millions of charging stations (no, markets will not make this happen magically)
    2. Regulations must force electric car companies to provide standard battery replacement systems (imagine a different battery compartment for each battery operated appliance you own!)
    3. Gas stations may need to be retrofitted and eventually replaced with battery swap stations for longer distance private travel.
    4. We need to fund research in better electricity storage and continuous charging using existing road infrastructure.
    5. Money? The true social cost of carbon could be $250 a ton, BC’s carbon tax is at $30 a ton, clearly we are all free-riding. Carbon taxes, financial transaction fees, taxing the rich and more need to happen.

    Are our governments and institutions up to this massive task?

  • Climate Deniers Get Top Science Posts

    Seriously, I’ve had enough of Bush North up here in Canada, he has to go and luckily, he’s only running a minority government, so it’s not 4 more years…

    globeandmail.com: Global warming critics appointed to science boards

    Top Canadian scientists are accusing the Harper government of politicizing science funding and jeopardizing climate research by naming global warming critics to key boards that fund science.

    The government’s actions are “dreadful,” said Garry Clarke, a leading international glaciologist at the University of British Columbia, and undercut public pledges to tackle climate change.

    “Their mouths are doing one thing and their hands are doing something different,” Prof. Clarke said.

    Already alarmed over funding cuts to basic research, scientists say two appointments in particular are worrisome. Mark Mullins, the executive director of the conservative-leaning Fraser Institute – and a former adviser to the Canadian Alliance Party – was recently appointed to the Natural Sciences and Engineering Research Council of Canada (NSERC), which funds university research projects that have included studies on climate change.

    Desmogblog has more, including choice quotes from the economists and oil geologists that run this country’s science.

    Mullins: “It strikes me that the science is not settled,” he said in a 2007
    interview posted at BCbusinessonline. “‘Put caps on global emitters’ is
    not the natural conclusion I would come to.”

    Weissenberger: “To those who doubt the scientific basis of global warming theory, we
    say: Don’t let a cabal of government-funded scientists, environmental
    activists and journalists convince us they’re the mainstream.” — April
    28, 2006″

    These are the people who will be deciding who gets science money in Canada.

    This has probably been the most unscientific administrations in Canada’s recent history.

    I think it is time to throw the bums out, it’s time for another election!

  • Cleaner Air Brings Drop in Death Rate – New York Times

    Cleaner Air Brings Drop in Death Rate – New York Times

    When air pollution in a city declines, the city benefits with a directly proportional drop in death rates, a new study has found.

    In other news, Dog bites man (I have never typed “dog bites man” into google news before – shocking…)

    Well, the Dockery and company published a seminal set of articles on the 6 city study back in the 90s that are the gold standard of air pollution epidemiology. It takes large long-term studies like these to establish even tenuous correlations, and their graphs connecting particle concentrations and mortality were beautiful straight lines.

    This follow up is pretty cool because the cities had made most of the reductions in the 70s and 80s after the passage of the Clean Air Act and this study clearly demonstrates that the bar for lowering mortality/cancer rates by lowering fine particle levels has not been reached yet. The abstract of the paper is below the fold.

  • John Kerry and the Environment

    The fight in the Senate | Gristmill: The environmental news blog | Grist

    Kerry, everyone’s favorite democrat summarizes the non-coal/auto democrat’s energy/environmental policy plans int he US senate.

    Highlights:

    1. Increase Fuel Economy standards
    2. Increase contribution of renewable sources
    3. No drilling in the Alaskan National Wildlife Refuge (ANWR)
    4. No liquid coal
    5. NO MORE COAL WITHOUT SEQUESTRATION!!!

    This is all very sensible. He does not mention biofuels/corn ethanol, which I guess is because he’s from Mass, not exactly corn central.

    He’s a good man, this John Kerry.
