The England Environment Minister Blogs

He seems to write it himself, has comments and all, some of which aren’t very friendly. One of his posts talks about a Carbon ration card, meaning everyone starts off with a set of carbon credits, which you can either use, or sell back to the trading bank so that people who use more carbon can buy more.

The principle is simple: there would be a decision about the nation’s
annual level of carbon emissions, permits/quotas for that level would be issued on a per capital basis (probably for personal food, household energy and travel emissions), and those who spent under the wuota would be able to sell to those who spend above.

Well put, and in classic blog style, no spellcheck!

Meanwhile, in the US, we have the chair of the powerful Senate Committee on Environmental and Public Works and well known Global Warming denier.

But coolness and hipness aside, it is refreshing for a minister (secretary, whatever you call them) to communicate in this fashion and be accepting of comments and criticism. We need a few more of these on the other side of the Atlantic (no,  not Antarctica, look West).

  • Virulent E-Coli strain lives in grain-fed cattle.

    Interesting side note about the spinach E-Coli outbreak

    Leafy Green Sewage – New York Times

    Where does this particularly virulent strain come from? It’s not found in the intestinal tracts of cattle raised on their natural diet of grass, hay and other fibrous forage. No, O157 thrives in a new — that is, recent in the history of animal diets — biological niche: the unnaturally acidic stomachs of beef and dairy cattle fed on grain, the typical ration on most industrial farms. It’s the infected manure from these grain-fed cattle that contaminates the groundwater and spreads the bacteria to produce, like spinach, growing on neighboring farms.

    Well, talk about unforeseen consequences, cows really should not eat grain. Go watch my favorite food cartoon ever, the Meatrix, and its most excellent sequel, The Meatrix 2: Revolting for more.

    When cows were switched from a grain diet to hay for only five days, O157 declined 1,000-fold. This is good news. In a week, we could choke O157 from its favorite home — even if beef cattle were switched to a forage diet just seven days before slaughter, it would greatly reduce cross-contamination by manure of, say, hamburger in meat-packing plants.

    Seems easy enough to implement, if impossible to enforce.

    March Babies not so Bright? – Pesticides to Blame?

    Byoliveridley

    An Indiana scientist makes a rather provocative argument that exposure to pesticides in the womb can explain why Indiana babies conceived in July-August (Born March and April?) have lower achievement scores than the other kids.

    ScienceDaily: Conception Date Affects Babys Future Academic Achievement

    Dr. Winchester and colleagues linked the scores of the students in grades 3 through 10 who took the Indiana Statewide Testing for Educational Progress (ISTEP) examination with the month in which each student had been conceived. The researchers found that ISTEP scores for math and language were distinctly seasonal with the lowest scores received by children who had been conceived in June through August.

    “The fetal brain begins developing soon after conception. The pesticides we use to control pests in fields and our homes and the nitrates we use to fertilize crops and even our lawns are at their highest level in the summer,” said Dr. Winchester, who also directs Newborn Intensive Care Services at St. Francis Hospital in Indianapolis.

    “Exposure to pesticides and nitrates can alter the hormonal milieu of the pregnant mother and the developing fetal brain,” said Dr. Winchester. “While our findings do not represent absolute proof that pesticides and nitrates contribute to lower ISTEP scores, they strongly support such a hypothesis.”

    Well, that is a bold leap of faith, and use of a correlation=causation argument that I don’t appreciate in most cases. Has this kind of work been done in other countries, or in urban environments without pesticide use?

    I am sure that many chemicals have subtle, but significant effects on developing fetuses. And the chemicals the authors mention have links with hypothyroidism..

    Nitrates and pesticides are known to cause maternal hypothyroidism and lower maternal thyroid in pregnancy is associated with lower cognitive scores in offspring.

    There is a link, but without further data, I think the conclusions are a stretch. But, something to keep in mind I guess if you live in Indiana and want to plan a baby!

    Disclaimer: I was conceived in June, and was in the upper echelons of achievement through school. So, by the power of personal experience, I am predisposed to scepticism. OTH, I grew up in a big city with consistently high pollution levels throughout the year and not much pesticide exposure.

  • Update: Canada's Carbon Targets Survive

    Byoliveridley

    In a vote today, the Canadian Parliament voted to keep debate on Bill C-311 alive. The vote was 155-137. This is good news, though the bill likely faces an uncertain future even if it passes parliament, thanks to Canada’s nominated and recently conservative majority senate. It was heartening to see the liberals vote en masse in favour of realistic targets. I am also attaching in verbatim, an email received from Michael Ignatieff’s office this morning on the bill.

    On behalf of Michael Ignatieff, I would like to acknowledge receipt of your recent email regarding Bill C-311, The Climate Change Accountability Act.

    Mr. Harper is isolated on the environment – he’s behind the provinces and our peer countries when it comes to taking leadership on climate change and the environment, and has undermined international progress at every turn.

    The Liberals are taking the Harper Conservatives to task over their failure to commit to a principled environmental policy backed up by real action. We’re calling on the government to immediately put in place a national climate change plan with economy-wide regulations on emissions and strategic investments in renewable and clean energy.

    Michael Ignatieff and the Liberal Party are also supporting Bill C-311 as part of our staunch opposition to Mr. Harper’s laissez-faire approach to the environment and climate change. We support its central principle – that Canada needs to take immediate, ambitious action to get us back on track to reducing emissions and improving our renewable energy sources.

    We must be clear, however: Bill C-311 is not a climate change plan. It picks targets, but it does not lay out a plan on how Canada can reach those targets. That’s where it comes up short. The Liberal Party has put forward a credible, achievable climate and clean energy strategy that will create jobs and make our economy – and our country – one of the cleanest and most competitive in the world. Canada cannot afford to miss this opportunity.

    Thank you for taking the time to write the office of Michael Ignatieff on this important issue.

  • More bad news for Nalgene

    Nalgene, and other so called safe hard plastics made from polycarbonates. Read here for background and all previous Bisphenol A postings.

    PLoS Genetics – Bisphenol A Exposure In Utero Disrupts Early Oogenesis in the Mouse

    In the course of studies to assess the effects of BPA on the mouse oocyte, we have uncovered a novel “grandmaternal” effect: exposure to BPA during pregnancy disturbs oocyte development in unborn female fetuses. When these fetuses reach adulthood, the perturbations are translated into an increase in chromosomally abnormal eggs and embryos. Thus, low-dose BPA exposure during pregnancy has multigenerational consequences; it increases the likelihood of chromosomally abnormal grandchildren. Our studies also provide mechanistic insight, and, surprisingly, suggest that BPA acts in the fetal ovary not by mimicking the actions of estrogen but by interfering with the function of one of the known estrogen receptors. Thus, our data suggest that estrogen plays a far earlier role in oocyte development than previously suspected and, importantly, raise the possibility that a variety of substances—both synthetic and naturally occurring—that mimic the actions of estrogen or act as estrogen antagonists may affect early oocyte development.

    Once again, caution is involved in the interpretation of the results, mice are more sensitive than humans to environmental exposures. The heartening part of this, and other recent studies is that work is now being carried out at doses that are more representative of ambient exposures, making results much more relevant. The part in bold is equally interesting. Estrogen is a very powerful hormone that has so many unknown effects on the body (and the mind, presumably :-;)

  • Energy efficiency, electricity, power plants

    Byoliveridley

    Suppose I paid you for every pound of pollution you generated and punished you for every pound you reduced. You would probably spend most of your time trying to figure out how to generate more pollution. And suppose that if you generated enough pollution, I had to pay you to build a new plant, no matter what the cost, and no matter how much cheaper it might be to not pollute in the first place.

    Well, that’s pretty much how we have run the U.S. electric grid for nearly a century. The more electricity a utility sells, the more money it makes. If it’s able to boost electricity demand enough, the utility is allowed to build a new power plant with a guaranteed profit. The only way a typical utility can lose money is if demand drops. So the last thing most utilities want to do is seriously push strategies that save energy, strategies that do not pollute in the first place.

    Energy efficiency, electricity, power plants | Salon News

    There are some things you wish you could have written, and the first paragraph is one of those. Romm nails it. Clearly, the most efficient MW of electricity is the one that was never used. But unless utilities are paid to conserve, not paid to produce, they will always build, build build.

    Excellent summary of arguments he makes all the time over at the gristmill. Now to find out what BC does. Canada is one of the worst in terms of energy use per capita. Some of it can be linked to the cold climate, but Germany is plenty cold too, and uses a third less per person.

    This article compares BC and California and finds BCHydro lacking in its incentives to save. The key is “decoupling”

    Significantly, California adopted regulations so that utility company profits are not tied to how much electricity they sell. This is called “decoupling.”

    BC’s per capita energy consumption is 0.26, well below the Canadian average and on the decline as Canada as a whole is getting worse. But more can be done.

    The key value judgment to be made here is that reducing energy use benefits all of us. The system should be set up in such a way that it benefits the utility as well. This way, they’re on the same side.

    Also, while a carbon tax is all well and good, it is not sufficient. Energy efficiency requires investment up front and people would rather pay 50 bucks a year in carbon tax than pay 300 bucks up front to insulate their homes better and save a 100 bucks a year in energy costs. Rebates only work if you have money up front. Giving people a $100 check is nice, but only if they spend it on improving energy efficiency. But, it’sjust money and we all know that money gets spent (beer, beer beer!) Subsidies work better as they reduce the cost of things. I would rather buy 10 compact fluorescent lamps for a buck each with the government chipping in the extra 10 bucks than get it back at the end of the year as a rebate, or pay 20c extra per incandescent lamp as a carbon tax.

    All rambling aside, a really good article on the value of energy efficiency.

  • The Onion on Conservation

    Byoliveridley

    This is so sad, though there is more than a kernel of truth to it. Individual efforts mostly make people feel better about themselves (hey, I recycle, makes me feel good!). It is the Onion and it does go too far. Of course individual efforts add up, and more importantly, force the important players like government and big industry to modify their behavior just a little bit (at least that is what I tell myself).

    I’m Doing My Inconsequential Part For The Environment | The Onion – America’s Finest News Source

    Every day, without fail, I meticulously organize my recyclables into five distinct categories, thereby subtracting an eyedropper’s worth of garbage from the countless tons of waste that ferment in our landfills. It only takes a few extra minutes, but just think of the impact it totally lacks. I also refuse to use anything but “Earth-friendly” paper products—some of which contain up to 10 percent recycled materials. For me, it’s worth shouldering the extra cost, but, unfortunately, only a scant few of us bother to do the same. And growing some of my own organic vegetables in my backyard garden also, to my immense gratification, reduces the use of toxic chemical-based pesticides and herbicides present in corporate farming techniques by as much as 0.0000000000000000000000000000000000000001 percent.

  1. yup, government minister bothering to explain his ideas in a blog.. pretty cool. Some of the comments on his blog are very interesting too. Examines more than one angle of the Carbon voucher concept.
