Snakes in NY

Byoliveridley

What fun, we saw three snakes hiking at the Turkey Mountain Nature Preserve in Westchester County, NY (the highest point in Westchester county, the information plaque claims that on a clear day, you can see the Manhattan skyline to the south). They were at different parts of the trail and we nearly stepped on them each time. They seemed in no hurry to escape and we got within a foot each time. Unfortunately, no camera except the cellphone, which is worse than no camera at all!

There were a couple of really sluggish rat snakes…

And there was a rather more active garter.

    Chemical & Engineering News: Latest News – Bisphenol A May Trigger Human Breast Cancer

    Soto and her colleagues exposed pregnant rats to bisphenol A at doses ranging from 2.5 to 1,000 µg per kg of body weight per day. By the time the pups exposed at the lowest dose reached the equivalent of puberty (50 days old), about 25% of their mammary ducts had precancerous lesions, a proportion three to four times higher than among the nonexposed controls. Mammary ducts from all other exposure groups showed elevated levels of lesions. Cancerous lesions were found in the mammary glands of one-third of the rats exposed to 250 µg/kg/day.

    Bisphenol A is used in the manufacture of polycarbonate plastics and epoxy resins. It is found in many food and beverage containers, including baby bottles. It is also found in canned food linings and dental composites, and it leaches from all of these products. In one study, Soto notes, urine samples from 95% of the human subjects contained the chemical.

    The Environmental Protection Agency has set a safe human intake dose of 50 µg/kg/day for bisphenol A. “On the basis of the effects observed in recent studies, this seems to be an unsafe level,” Soto says.

    Bisphenol A is old news, BTW, people have known for a while about this chemical’s propensity to carcinogenicity. Of course, there’s that whole argument about pregnant mice being more susceptible to chemicals than humans, etc. So, the jury is still out. but Soto is right, 50 µg/kg/day seems to not provide enough of a safety factor. The EU uses 10 µg/kg/day, though they do say that

    realistic worst-case estimates of consumer exposure via foodstuffs, range from 0.00048 mg/kg bw/day for adults to 0.0016 mg/kg bw/day for infants, which is well below the maximum exposure level

    Of course, who knows what additive effects this chemical may have with the multitude of other chemicals floating around. Doing tests of single chemicals and trying to link that to epidemiological data is a perilous undertaking, the connections are tenuous most of the time and the plastics companies routinely fund studies that prove otherwise, because as you know, if you know what you’re going to find before you study it, you will find it!

    Read the wikipedia stub on polycarbonates. Us yuppies who drink religiously from Nalgene bottles to avoid phthalates and nasty tastes would do good to take note! I guess glass is the best, though it does have that annoying tendency to shatter when dropped… Water from glass bottles do have the best taste, though.

    tdcAn act of quite some chutzpah, “outbidding” oil and gas companies in a public land auction. The land was going over for even more oil and gas exploration at a time when we should really be ramping down gas and oil usage.

    More on contributing to his cause here. He needs 45,000 dollars in downpayment to the US government to keep the process going. He appears to be well on his way, but needs some more money to get over the top. It is more than likely that the Obama administration is going to cancel the land grab process anyway, so he will be off the hook soon enough.

    Audacious, brilliant and brave.

    One Utah » Blog Archive » Why I Disrupted A Fraudulent Auction.

    Yesterday I decided that the crisis facing us requires more critical action than has been taken in the past. When faced with the opportunity to seriously disrupt the auction of some of our most beautiful lands in Utah to oil and gas developers, I could not ethically turn my back on that opportunity. By making bids for land that was supposed to be protected for the interests of all Americans, I tried to resist the Bush administration’s attempt to defraud the American people.

    At this point it appears that I was successful in my attempts to disrupt this fraudulent auction. The federal officials who took me into custody said that I cost the oil companies in the room hundreds of thousands of dollars and prevented 22,500 acres of land from being sold for fossil fuel development. I had a very open conversation with the federal agents about my motivations and values. They were friendly, respectful, and somewhat sympathetic.

  • US, India and China Talk Climate

    Byoliveridley

    The Obama administration is hoping to win new commitments to fight global warming from China and India in back-to-back summits next month, the Guardian has learned, including the first Indian emissions trading scheme.

    The US hopes the new commitments will breathe life into the moribund negotiations to seal a global treaty on climate change in Copenhagen in December, by setting out what action each country will take. But many observers say such bilateral deals also risk seriously weakening any Copenhagen agreement by allowing the idea of a global limit on greenhouse gas emissions to be abandoned.

    The Guardian

    So, as part of Blog Action Day 2009, which is focusing on climate change, I bring you news that the US administration is back, taking some kind of a leadership role in climate change by talking to India and China. The notion that somehow what the US, Europe and Canada do in response to climate change is pointless because China and India are not going to participate is misleadingly inaccurate, sometimes deliberately so. I had written in June about India’s very ambitious solar policy, and China has similar, fairly comprehensive programs on climate change.

    The concern that bilateral talks will somehow sabotage the multilateral Copenhagen negotiations is, I think, overstated. More talk is always better, and good things happen when the world’s most high profile polluter signals its willingness to talk, and even initiate talks with countries whose development paths are at a critical stage.

    I have not been super hopeful about how things are going to turn out in the next few years. But things have changed quite a bit in the past year. The US appear to have their own climate bill brewing. Europe makes the right noises and has a head start,making the mistakes early. Unfortunately, Canada has given up the ghost thanks to our troglodyte oil man administration. Our main hope now is that the US passes a strong enough bill to affect Canada. Or there is an election leading to a change in administration and Mr Michael Ignatieff and the “liberals” are true to their word on a new, sustainable energy policy.

    Canada is now the worst laggard, having extremely high per capita emissions and policy to increase these emissions while actively sabotaging climate talks. We emit a full 2% of all global warming contributors while accounting for about 0.5% of the world’s population. It is understandable given our development path how we got there, but not trying to fix it is criminally negligent and morally bankrupt.

    Apparently, the Canadian people could care less, polls indicate that the business as usual administration is increasing its support among Canadians. What is the average Canadian’s responsibility if he/she knowingly supports policy that could lead to mass homelessness, flooding, starvation, wars, species extinction, etc?

    On Climate blog action day, I am sad to report that my adoptive country will do nothing but soldier on in its destructive behaviour. No point calling my local MP, she agrees with me!

    Water Find to End Darfur War – Well, not so fast!

    Byoliveridley

    Beware the dangers of the overhyped press release machine (or sciencedaily, pick your poison). All Farouk El-Baz saw when he did the radar study was a giant depression. It is TBD whether there’s water in them thar holes!’

    BBC NEWS | Africa | Ancient Darfur lake is dried up

    Alain Gachet, who used satellite images and radar in his research, said the area received too little rain and had the wrong rock types for water storage. But the French geologist said there was enough water elsewhere in Darfur to end the fighting and rebuild the economy.

    On Wednesday, Boston Universitys Farouk El-Baz said he had received the backing of Sudans government to begin drilling for water in the newly-discovered lake, in North Darfur.

    No wonder they say that water is the 21st century oil. This guy’s going to be drilling for water (also known as well digging!).

    Indian Parliament Discusses Climate Change

    Byoliveridley

    India stresses on Kyoto standards-India-The Times of India

    The discussion on global warming in Parliament will end with the statement of environment minister A Raja, possibly on Monday. He is bound to restate the country’s position on climate change in the international arena — that countries must bear “a common but differentiated responsibility” for climate change, a phrase that is the central pin of the Kyoto Protocol.

    De-jargonised, it means, while every country is adding to the problem, there are some that are more responsible than others, and should, therefore, bear the burden and costs of cleaning up more than the smaller culprits

    More highlights…

    The US, between 1950-2003, emitted 10 times more carbon dioxide than India did. Europe emitted 8.5 times more. Yet US and Australia, two of the biggest emitters of greenhouse gases, have refused to ratify the Kyoto Protocol (which asks developed countries to reduce their emissions) on the pretext that developing countries like India and China are not undertaking emission cuts.

    Worse still, if one looks at per capita emissions from different countries, which is a more equitable way of calculating emissions if one was to go by the principle that each person has as much right to the atmosphere as another, then India ranks a mere 120 compared to US which ranks 6 and Australia 10 on the culprits’ list. This is taking the emission levels of 2003.

    Well, they are right, and they are wrong too. The developed world has a lot to more to cut back on and should make the bulk of the cuts. But India and China also need to grow using current state of the art knowledge, not using the 1950s coal intensive, energy inefficient model of increasing supply without paying attention to demand. We have also come to realize that IPCC reports, due to their consensual nature, are conservative. So, they will tend to understate the effects of climate change and overstate the costs. It may not be as expensive in India and China as long as attention is being paid to hw the infrastructure is being developed.

  • Deep Sixing California’s Prop 65

    Byoliveridley

    House mulls bill on food label removal – Boston.com:

    “This bill would strip state governments of the ability to protect their residents through state laws and regulations relating to the safety of food and food packaging,” the attorneys general wrote.

    The obvious target, they said, is California’s Proposition 65, a law passed by voters requiring companies to warn the public of potentially dangerous toxins in food. The law has prompted California to file lawsuits seeking an array of warnings, including the mercury content in canned tuna and the presence of lead in Mexican candy.

    Prop 65 is a California Law that requires the state of California to “publish, at least annually, a list of chemicals known to the state to cause cancer or reproductive toxicity” and for businesses to post warning labels. Well naturally, it kinda depresses sales of canned tuna if you have mercury warnings on the labels, mmm, lead in my candy, so delicious…

    This is obviously not good for the consumer, I undestand that businesses feel the burden of extra labeling, depressed sales, etc, but why should the onus always be on the consumer? If the assumption that it is the consumer’s responsibility to find out that there is mercury in his/her tuna and that the informed consumer will make informed choices, why not make it easier on the consumer to find out and then rely on him/her to make that choice? What are the companies afraid of, exactly?
