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).

  • Drugs in the water: Behold the power of synergy

    funky MathES&T Online News: Can drugs found in water harm humans?

    Researchers agree that aquatic species face the greatest risk from exposure to low levels of pharmaceuticals, such as synthetic hormones, which can act as endocrine disrupters at environmental levels. However, little is known about the potential human health effects arising from complex drug mixtures.

    Well, it is often more difficult to analyze complex mixtures because Experimental Design 101 makes you want to isolate the effects. And when you do compounds one by one in series, the tendency is to always add them up from the individual experiments. Unfortunately, body chemistry is not like that. I’ve always wanted to design a study that started complex and then tried to isolate later.

    To his surprise, Pomati observed that this mixture of drugs at environmental levels inhibited the growth of human embryonic kidney cells. After 48 hours of exposure, cell proliferation was reduced by 10–30% compared with controls. However, no inhibition was observed when cells were exposed to only the toxic cancer drug at environmental levels.

    Well, that seems conclusive enough, but here comes the “Experimental Design 101” Scold:

    The results show that the growth inhibition is not due to the single most cytotoxic compound alone. But that does not conclusively prove that synergistic or additive effects exist between drugs in the mixture, cautions Thomas Heberer of the Institute of Food Chemistry at the Technical University of Berlin. To show that the individual drugs behave additively, Heberer suggests that researchers should analyze the effects of compounds with a common mode of action, such as antibiotics, alone and in various mixtures.

    No, No, and No. Doing this presupposes that you know that mechanism of action, meaning you’ve half answered your question. The question Heberer is trying to answer is “do individual drugs with the same mode of action behave additively”. The question Pomati is trying to answer is “Can we demonstrate cytotoxic effects of a cocktail of drugs at ambient levels in a laboratory setting”? These are two completely different questions and Pomati’s question is more valuable at this point in time. Heberer’s strategy, on the other hand, will keep a lab well funded for years to come! But, it is very much the final step.

    It is more important at this point in time to demonstrate other effects such as endocrine disruption, mutagenicity, etc in the lab at environmentally relevant levels of mixtures. Then we can get a better handle on which  effects are relevant and which ones to ignore.

    On Google map, everythings back to normal after Katrina | Chron.com – Houston Chronicle

    Byoliveridley

    TBTB (Too busy to blog), but this struck me as very weird.

    On Google map, everythings back to normal after Katrina | Chron.com – Houston Chronicle

    Google’s popular map portal has replaced post-Hurricane Katrina satellite imagery with pictures taken before the storm, leaving locals feeling like they’re in a time loop and even fueling suspicions of a conspiracy.

    Scroll across the city and the Mississippi Gulf Coast, and everything is back to normal: Marinas are filled with boats, bridges are intact and parks are filled with healthy trees.

    “Come on,” said an incredulous Ruston Henry, president of the economic development association in New Orleans’ devastated Lower 9th Ward. “Just put in big bold this: ‘Google, don’t pull the wool over the world’s eyes. Let the truth shine.’ “

    I am sure there is the usual, non-conspiracy involving explanation to all of this, and I don’t know enough about NO geography to even verify this fact, but an explanation would be nice!

    Update:

    Turns out there was a major upgrade of the imagery on the 29th of March. Still does not explain the above…

  • Nanoparticles the new asbestos?

    Byoliveridley

    I am sure everyone has heard about the wonders of nanotechnology, but what about the other side?

    ScienceDaily: Tiny Inhaled Particles Take Easy Route From Nose To Brain

    In a continuing effort to find out if the tiniest airborne particles pose a health risk, University of Rochester Medical Center scientists showed that when rats breathe in nano-sized materials they follow a rapid and efficient pathway from the nasal cavity to several regions of the brain, according to a study in the August issue of Environmental Health Perspectives

    There was a time when asbestos was the wonder material, malleable and fire resistant, capable of being woven into sheets, and being incorporated into buildings for fire retardation. Unfortunately, many cases of asbestosis and mesothelioma later, not so wonderful. Asbestos is a special case because the fibers started out big and would keep breaking down into smaller particles till they reached that magic size range between 0.1 and 1-2 um where they could stay suspended in the air for a long time, and also take advantage of the lungs’ inability to filter particles that size to any great degree of efficiency.

    Nanoparticles are an order of magnitude smaller, and hence behave more like gases. They may  also contain choice toxic heavy metals such as manganese which are not usually floating around in the air at these small sizes. So, this study is a little scary, especially for the folks in the manufacturing end of things, these miracle particles seem to be going straight to the brain. Traditional masks and air handling systems are not designed to filter such fine particles, so I am sure they’re floating around in the air waiting to be breathed in.

    Update 9:00 AM, 8-3-2006
    Well, I swear, I did not see this before I wrote this morning!

    The question of the day, however, is are they safe for humans and other living things? Earlier this year, Andrew Seaton, A U.K. scientist who was the lead author of a 2004 report investigating the saftey of nanotechnological materials raised a bit of a ruckus by comparing carbon nanotubes to asbestos fibers. Asbestos once had its day in the sun as an all-purpose wonder material. But then we learned that tiny asbestos fibers, once ingested by the human body, could be extremely deadly. Carbon nanotubes: also easy to ingest, and exquisitely capable of penetrating cell structures. Could they be equally toxic?

    Killer nets reinstated

    Council Decisions: March 2006

    Drift Gillnet Management

    The Council adopted a recommendation to NMFS to authorize an exempted fishing permit (EFP) that would allow drift gillnet fishing in the current August 15-November 15 closed area. The EFP fishery would be governed by several requirements for all vessels, including, to carry an observer; to limit total fishing effort in the EFP fishery to 300 sets; to immediately cease the EFP fishery if, and when, two leatherback sea turtles were encountered by the fishing gear; and to immediately cease the EFP fishery if one mortality or serious injury occurred to any of the following marine mammals: short-finned pilot whale, sperm whale, fin whale, gray whale, humpback whale, or minke whale.

    And, with that, starts the rather egregious practice of drift gillnet fishing. The restrictions seem fairly tight, an observer on every boat, and end to the fishery after two incidences of capture. There is definitely more than meets the eye here, I don’t know what. Drift gillnet fishing is well documented to cause turtle catch, this from the 1998 Fishery Bulletin for 1990-1995

    In the drift gillnet fishery, seven out of 387 mammals observed entangled were released alive. In the set gillnet fishery, five out of 1,263 mammals observed entangled were released alive. Estimates of incidental kill are presented along with estimates of entanglement for species that were observed to be released alive. For the period under consideration, the estimated mortality for the drift gillnet fishery was over 450 marine mammals each year. A total of 20 turtles and 3 seabirds were observed entangled during the entire period. The most frequently entangled species in this fishery were common dolphins, Delphinus spp., and northern elephant seals, Mirounga angustirostris. Estimated cetacean mortality in the driftnet fishery decreased from 650 in 1991 to 417 in 1995; pinniped mortality decreased from 173 in 1991 to 116 in 1995. Estimated cetacean mortality in the set gillnet fishery ranged from a high of 38 in 1991 to a low 14 in 1993; pinniped mortality rose to a high of 4,777 in 1992 and then decreased to 1,016 in 1995. We postulate that there has been a decline in the number of pinnipeds and cetaceans in the setnet fishery owing to area closure. No similar proposal can be made for the driftnet fishery. The most frequently entangled mammals in the setnet fishery were California sea lions, Zalophus californianus, and harbor seals, Phoca vitulina. Six turtles and 1,018 seabirds were estimated entangled in this fishery during the NMFS Observer Program from July 1990 to December 1995.

    So what’s the deal, this thing caught 20 turtles in 5 years, so it is going to catch turtles, no doubt about it. Anyone who does not get what the death of one adult sea turtle means read this. Sea turtles are wonderfully fragile animals given their size, they take long to mature sexually, they do not breed all that much and less than 1% of turtle hatchlings survive to adulthood. Leatherbacks are highly endangered.

    I have a feeling that this is the first part of a one-two punch intended to reinstate the famed turtle killer long line swordfish nets on the pacific coast. The “proof” that these nets do not catch turtles will be used to lobby for longline swordfishing in, oh say three months?

  • “Boutique” Fuels still fashionable – EPA

    Byoliveridley

    So, when someone says something that is refuted rather indisputably by one of their agencies, maybe a retraction is in order? I won’t hold my breath, but this is good news. Region-specific pollution problems require and demand region-specific solutions. It is as “Boutique” as saying you have to vacuum a carpet and sweep a wooden floor. But, as we all know, the first step to vilifying something is to give it a French appellation.

    EPA: Special fuels not to blame for costs

    EPA: Special fuels not to blame for costs

    By H. JOSEF HEBERT, Associated Press WriterThu Jun 22, 4:38 PM ET

    “Boutique” gasoline blends to help states meet clean air rules are not a factor in higher prices as President Bush has suggested, says a draft of a study ordered by the White House.

    Although often cited as a reason for volatile gasoline prices, so-called “boutique fuels” have not caused unusual distribution problems or contributed to price increases, the report concludes.

    The review was conducted by a task force headed by the Environmental Protection Agency and involving representatives from the 50 states as well as the Energy and Agriculture departments.

  • Clubbing baby seals

    Byoliveridley

    Regarding the recent brouhaha that started with the EU banning Canada’s seal products, I confess to being in two minds about Canada’s sealing practices. Of course, clubbing baby seals to death seems barbaric, but so is confining pigs (intelligent and cute in the right circumstances!) to pens where they can barely move and slaughtering them, so is de-beaking chickens and cooping them up in ultra small cages, so is fattening cows with growth hormones, then slaughtering them. If you have any questions, I give you

    and this:

    and this too:

    Okay, now that you have become part of the meatrix, why is industrial animal farming, which is way more destructive on the planet, the people involved and the animals completely and utterly acceptable while the (admittedly barbaric) “culling” of a small proportion of a wild population of seals is banned?

    Yes, seals are cute, but so are chickens, baby pigs, calves, you name it, I even think most snakes are cute, it’s all optics anyway.

    If you’re against the seal clubbing, you need to be against all current animal farming practiced in all of the Americas, and yes, Europe as well.

    FAQs: The Atlantic seal hunt

    Few facts in this debate go unchallenged. All sides agree on where and when. But the answers to how, why, and even how many aren’t as clear. 

    Even the language is chosen carefully. Hunt or slaughter. Sea mammals or baby seals. Cherished tradition or economic disaster. Cod-eating nuisance or adorable innocent.

    The images of the hunt are even more powerful, and seal hunt opponents know it. Most people find the pictures difficult to watch, but supporters say the same kind of thing happens in slaughterhouses — places where cameras aren’t allowed

One Comment

  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.
