Wow, Conventional Milk makes Twins!

44m.jpgHoly tentacular twins, Batman! This is crazy news, the first study linking the incidence of twins with environmental factors. The culprit is growth hormone fed to cows to increase milk production. According to this Wikipedia article, a third of all dairy cattle use Monsanto’s rBGH (or rBST) brand Posilac®, so obviously, use is widespread.

FEED – July 2006 (from the Union of Concerned Scientists)

1. Engineered hormone in milk may be linked to twinning. A recent study found that women who consumed dairy products were five times more likely to give birth to twins than vegan women. The study suggested that the use of engineered bovine growth hormone/bovine somatotropin (BGH/BST) to boost milk production in dairy cows may be related to the higher level of twinning. BGH is known to increase twinning in dairy cows. In addition, the rate of human twinning is twice as high in the United States, where BGH is used, as in Britain, where BGH is banned. BGH affects twinning rate by increasing insulin-like growth factor (IGF), a protein produced in the milk of both animals and humans, that promotes ovulation and may help early-stage embryos survive. A separate study found that levels of IGF were 13 percent lower in vegan women than in women who consumed dairy products. Read a press release about the study, which was published in The Journal of Reproductive Medicine.

If true, no woman should ever drink “conventional” milk (non-organic, non rGBH free, etc). Twins are fun, I love my twin nieces very much, but they are much more difficult to carry and deliver, and there are more complications.

Scary, but I suspect this is the tip of the iceberg as far as environmental effects on childbirth are concerned.

  • Oceans of Carbon Dioxide?

    Well, possibly the biggest climate change science news of the day, sequestration with a twist. Now if we can only get those friendly little carbon dioxide molecules to march down a couple of miles down to the ocean sediments to sequester themselves! But seriously, it will take a lot of pumping.

    Permanent carbon dioxide storage in deep-sea sediments — House et al., 10.1073/pnas.0605318103 — Proceedings of the National Academy of Sciences

    Stabilizing the concentration of atmospheric CO2 may require storing enormous quantities of captured anthropogenic CO2 in near-permanent geologic reservoirs. Because of the subsurface temperature profile of terrestrial storage sites, CO2 stored in these reservoirs is buoyant. As a result, a portion of the injected CO2 can escape if the reservoir is not appropriately sealed. We show that injecting CO2 into deep-sea sediments <3,000-m water depth and a few hundred meters of sediment provides permanent geologic storage even with large geomechanical perturbations. At the high pressures and low temperatures common in deep-sea sediments, CO2 resides in its liquid phase and can be denser than the overlying pore fluid, causing the injected CO2 to be gravitationally stable. Additionally, CO2 hydrate formation will impede the flow of CO2(l) and serve as a second cap on the system. The evolution of the CO2 plume is described qualitatively from the injection to the formation of CO2 hydrates and finally to the dilution of the CO2(aq) solution by diffusion. If calcareous sediments are chosen, then the dissolution of carbonate host rock by the CO2(aq) solution will slightly increase porosity, which may cause large increases in permeability. Karst formation, however, is unlikely because total dissolution is limited to only a few percent of the rock volume. The total CO2 storage capacity within the 200-mile economic zone of the U.S. coastline is enormous, capable of storing thousands of years of current U.S. CO2 emissions.

    Melamine Adulteration investigation gets cracking

    FDA agents raid pet food plant, offices – Yahoo! News

    WASHINGTON – Federal agents searched facilities of a dog and cat food manufacturer and one of its suppliers as part of an investigation into the widening recall of pet products, the companies disclosed Friday. Food and Drug Administration officials searched an Emporia, Kan., pet food plant operated by Menu Foods and the Las Vegas offices of ChemNutra Inc., according to the companies. Menu Foods made many of the more than 100 brands of pet food recalled since March 16 because of contamination by the chemical melamine. ChemNutra supplied the manufacturer with wheat gluten, one of the two ingredients tainted by melamine used in recalled pet products. Both companies said they were cooperating with the investigation.

    The initial “let’s blame China for everything” drumbeat is subsiding a little as the FDA finally begins its inspections, and we find the tangled web of the food import business unraveling just a little bit. At this point in time, the charges are flying like crazy.

    The origin within China of the wheat gluten and rice protein concentrate remains murky. For example, ChemNutra’s source for the twovegetable proteins, Suzhou Textile Import and Export Co., told The AP that food ingredients aren’t part of its business — but that employees often take on side deals. Stern said ChemNutra dealt with the company’s president.

    Side deals? How quaint? The solution is simple: Quarantine every food item from China until it has been tested for melamine. You do not know the extent of the problem yet. It only seems to get worse everyday. Make the manufacturers pay for the testing.  Tighten up the paperwork, exercise tighter control over where the ingredients come from, get everything in writing.

    Meanwhile, the manufacturers are getting their press releases out. From Blue Buffalo foods…

    We at the Blue Buffalo Company have just learned that American Nutrition Inc. (ANI), the manufacturer of all our cans and biscuits, has been adding rice protein concentrate to our can formulas without our knowledge and without our approval. This is product tampering, and it apparently has been going on for some time. The can formulas that we developed, and trusted them to produce, never contained any rice protein concentrate. It appears that only an FDA investigation of ANI’s rice protein concentrate supplies forced them to reveal this product tampering to us.

    While this activity by ANI is in itself unlawful, the situation is further clouded by the fact that ANI has been receiving rice protein concentrate from Wilber-Ellis, some of which the FDA has determined to be contaminated with melamine.

    If this is true (and we don’t know that for a fact), it’s plain ol’ cheating and food adulteration. What does American Nutrition have to say?

    The FDA has urged American Nutrition to issue a voluntary recall of pet foods manufactured using Wilbur-Ellis rice protein. None of these products is sold under an American Nutrition brand, but are sold through other independent companies. No American Nutrition brands or other products they manufacture for other businesses are affected by this recall.

    Why would I trust the word of anyone who’s accused of adding ingredients off the label? This story gets curiouser and curiouser, and it is pretty clear that between the “side dealers” in China and some greedy middlemen suppliers here, we have plenty of blame to go around.

    Stay tuned for more…

    The oceans cannot absorb infinite amounts of CO2

    While North Carolina and most of the South of the US reels under drought like conditions and the local newspaper is filled with all kinds of stories about water shortages, this one sentence, steeped in science-speak has caught the attention of climate scientists and general climate change worriers.

    The third process is indicated by increasing evidence (P =0.89) for a long-term (50-year) increase in the airborne fraction (AF) of CO2 emissions, implying a decline in the efficiency of CO2 sinks on land and oceans in absorbing anthropogenic emissions.

    Huh? What they’re saying is that while increasing CO2 emissions are rightfully blamed for the bulk of global warming, a not insignificant (18% to be precise) percentage can be linked to the fact that the oceans just are not absorbing CO2 at the rate that they used to. The reasons are yet unclear, but the trend can definitely be seen.

    OceanUptake.jpg

    The noise in the data is clear indication that there are many natural factors that greatly influence this uptake. But recent observational studies (not a free paper, look up reference 2, so I won’t link to it) in the North Atlantic are backing up this trend.

    The reasons could be as simple as decreasing solubility with increasing temperature, or with increasing ocean acidity, who knows. But it points in the general direction of our climate models being in danger of underestimating climate change effects.

    What does this mean for climate research? Well, there was a really interesting paper out in Science today (Reference 3, not free!) talking about the uncertainties in climate change estimates. The best guess (95% confidence interval) is between 2 and 4.5 degrees Celsius rise in temperature with doubling of CO2 levels in the atmosphere. But the probability graph around this estimate is not symmetrical, it has a long tail towards the right (>4.5 degrees). The paper discusses why this uncertainty is not related to model limitations, but is an inherent feature of the way climate change processes work, through non-linear feedbacks and multiplying processes.

    What these observations tell us is that uncertainty in climate estimates is not a bug, it’s a feature and will never go away. Also, all the uncertainty is on the wrong side, meaning we’re always in danger of underestimating climate change. There goes one more excuse for not tackling climate change with all the urgency it deserves.

    We will never predict how bad it will be, we only know it will be pretty bad, possibly worse.

  • Canada's Budget – FAIL on Renewables

    Canada's Conservative government released a federal budget last week that would kill off the country's main program for developing renewables and channel most of the money from a new “Green Infrastructure Fund” into carbon capture and storage CCS technology, or so-called “clean” coal.

    Of course, the carbon capture is not aimed at coal here specifically, but at the oil sands. More bad news –

    The new pro-coal budget effectively killed all support for the nation’s ecoENERGY Program for Renewable Energy (equivalent to America’s Production Tax Credit for renewables). The program was the nation’s main support mechanism for developing renewable energy. The Pembina Institute, a Canada-based sustainable energy think tank, reacts to the budget defeat:

    “The federal government’s failure to renew and expand this program has jeopardized at least 1,500 megawatts of “shovel read” wind energy projects across the country, while putting the brakes on billions of dollars of potential future investment.”

    The renewable energy industry had hoped for a five-year extension of the program in the budget, which would have spurred over $6 billion of private investment in the Canadian economy and created 8,000 jobs, according to the Institute.

    Note that this is not just the Conservatives. The Liberals are supporting this budget, and Liberal leader Michael Ignatieff has spoken glowingly about the oil sands industry.

    At this point, we do not control our own environmental future. The Conservatives are an Alberta centred party and their motivation is not surprising. The Liberals clearly want back in power and do not have the money to fight another election next month. Canadians seem to not favour the most logical option, a coalition government of the left leaning parties which make up a majority of seats and voting percentages in parliament, so the Liberals have to support the Conservative budget or face an election soon.

    With Ignatieff leading the Liberals, they know that all they need a little time to get money and reverse their losses from the previous election. His personal popularity advantage over previous Liberal leader Stephane Dion will most probably lead to better election results, especially if the Canadian economy continues to tank. A Liberal budget would have not killed the renewables, but would have not done anything to make the oil sands projects pay for all their externalities either.

    With the two main parties objectively in favour of unproven boondoggles and greenwashing, only firm decisive action by the US administration to institute some kind of carbon controls will change the game in Canada. My fear is that by killing money support at a critical time, you kill the renewables industry and disperse its people elsewhere, and no reversing course in 3 years will get those people and companies back.

  • NASA chief not worried about climate

    Ladies and gentlemen, I give you the chief of NASA, Michael Griffin

    NASA chief not worried about climate – Yahoo! News

    I guess I would ask which human beings, where and when, are to be accorded the privilege of deciding that this particular climate that we have right here today, right now, is the best climate for all other human beings. I think that’s a rather arrogant position for people to take,” Griffin said.

    Nothing more to say other than if I were American, I would first be a little ashamed, I would then start demanding his resignation. This is the chief of one of this country’s premier scientific institutions, one that does a lot of weather and climate research, one that employs the world’s foremost scientific voice on global warming. Here’s what Hansen had to say…

    James Hansen, a top NASA climate scientist, said Griffin’s comments showed “arrogance and ignorance,” because millions of people will likely be harmed by global warming in the future.

    Wow, he was being kind.

  1. Cool, one more thing that I can safely do that a woman. Or wait….does it make a difference if a man drinks the milk and then … you know… does the happy? Dang!

    I’m lactose intolerant anyway, like over 90% of South Indians. I’m glad to just not throw up. I like my coffee without cream, thank you.

  2. Nope, it\’s all on the woman\’s side! Of course, this is not why milk plays such a prominent role in Tamil movies (\”first night\”, anyone!), most Indian milk is hormone free, hormones being a little too expensive.
