Three workers killed, six injured in Utah coal-mine rescue effort Three rescue workers were killed and at least six others injured when a section of Utah’s Crandall Canyon coal mine caved in Thursday night. The workers were involved in the nine-day effort to reach six miners trapped deep within the mine. Seismic activity has caused […]

The tragedy grows

Two Three rescue workers were killed and at least seven six others injured when a tunnel collapsed in Crandall Canyon mine, the site of a rescue operation attempting to reach six miners that have been trapped inside for what is now 11 days without contact. Mine officials are discussing whether to shut down the rescue […]

Environmental scientist Theo Colborn warns about the chemicals all around us

This guest essay comes from Theo Colborn, an environmental health analyst, professor of zoology at the University of Florida, Gainesville, and president of The Endocrine Disruption Exchange (TEDX). She's one of the experts featured in Leonardo DiCaprio's new eco-documentary The 11th Hour, which opens in L.A. and New York on Aug. 17 and in other spots around North America on Aug. 24.

What a crazy world we live in when almost everyone knows what the acronym ED stands for. Millions of dollars have been poured into creating awareness of ED, erectile dysfunction, because it is profitable. This 21st-century sales-pitch strategy -- "disease mongering" -- has proven to be good for the bottom line. The irony of all this is that there is another ED out there into which millions have also been poured -- to keep it a secret. That ED is endocrine disruption, and if the public were to learn about it, bottom lines could shrink instead of grow.

Endocrine disruption should be right at the top of the list of most critical technological disasters facing the world today, up with climate change. With little notice, vast volumes and combinations of synthetic chemicals have settled in every environment in the world, including the womb environment. Synthetic chemicals at very low concentrations in the womb change how genes are programmed, cells develop, tissues form, and organs function, and thus undermine the potential and survival of developing animals, including humans. The chemicals threatening the integrity of future generations are derived from the processing of crude oil and natural gas, the same processes that are driving climate change. This is an integral part of the climate change story.

Scientists try to reduce methane emissions by tweaking cow diets

Did you know that cows belch every 40 seconds? I did not. A recent article in The Christian Science Monitor states this fun fact, and goes on to explain how scientists are trying to manipulate bovine diets to reduce the amount of methane that they emit:

In nontechnical terms

For those wondering why the planet hasn't yet exceeded the 1998 El Niño-fueled temperature record, a new Science magazine article ($ub. req'd) explains why. Basically, in addition to the steady increase in anthropogenic warming from greenhouse gases, you have to add a smaller variation from climate oscillations linked to the oceans. Those oscillations have been tamping down temperatures a tad, and will keep doing so for the next couple of years, but the decade of the 2010s is going to bring a return to record-smashing temperatures:

Our system predicts that internal variability will partially offset the anthropogenic global warming signal for the next few years. However, climate will continue to warm, with at least half of the years after 2009 predicted to exceed the warmest year currently on record.

Cats are the canaries of PBDEs

This is my cat, George. He is fat and grouchy, but I love him. He likes to sun himself on the patio.

This is a link to Sightline's research on PBDEs, toxic flame retardants. A couple of years ago, we conducted a study of PBDEs and found high concentrations in the breast milk of nursing mothers throughout the Pacific Northwest. It was bad news.

And what's the connection to George? Well, new scientific research shows that PBDEs are making house cats sick. (Major hat tip here to Lisa Stiffler, ace environmental reporter at the Seattle Post-Intelligencer, who covers the story in her blog today.)

From a summary of the study:

PBDE concentrations in blood serum of the 23 house cats participating in the study were 20-100 times higher than the median levels of PBDEs in people living in North America, who have been shown to have the world's highest human PBDE levels.

PBDEs are long-lived. They're found in foam cushions, TVs, computers, carpet pads, curtains, you name it. It's thought that we humans get our exposure to PBDEs through house dust, which often includes crumbled bits of foam and other goodies. Same goes for cats: researchers believe that felines, with their obsessive-compulsive grooming, are literally lapping up the toxic compound. And many cats (George included) eat a lot of fish, which tends to have high concentrations of toxics, too.

Wikipedia Scanner reveals orgs that edit Wikipedia articles

Ah, Wikipedia. Many of us at Grist frequently use this resource, but we do so knowing that just about anyone can edit a Wikipedia article at anytime. So, can we really trust the information contained within?

Fear not! As Wired reports, there is a new tool that sheds some light on who is editing what:

On November 17th, 2005, an anonymous Wikipedia user deleted 15 paragraphs from an article on e-voting machine-vendor Diebold, excising an entire section critical of the company's machines. While anonymous, such changes typically leave behind digital fingerprints offering hints about the contributor, such as the location of the computer used to make the edits.

In this case, the changes came from an IP address reserved for the corporate offices of Diebold itself. And it is far from an isolated case. A new data-mining service launched Monday traces millions of Wikipedia entries to their corporate sources, and for the first time puts comprehensive data behind longstanding suspicions of manipulation, which until now have surfaced only piecemeal in investigations of specific allegations.

Wikipedia Scanner -- the brainchild of Cal Tech computation and neural-systems graduate student Virgil Griffith -- offers users a searchable database that ties millions of anonymous Wikipedia edits to organizations where those edits apparently originated, by cross-referencing the edits with data on who owns the associated block of internet IP addresses.

Yet another one

As a physicist, I have never been a big fan of Freeman Dyson. He was, after all, one of the "geniuses" pushing Project Orion -- the absurdly impractical idea of creating a rocket ship powered by detonating nuclear bombs -- I kid you not!

Dyson has written a new book, A Many Colored Glass, that you shouldn't waste your time and money on -- as this extract on global warming makes clear. Dyson has basically joined the famous-crackpot camp with Michael Crichton and Bill Gray. You can read a good debunking of Dyson here. I'll add my two cents.

Subsidizing drivers needs to end

This article in the NYT highlights the absurdity of current transportation policy. While New York City is trying to get federal funding to help it pay for a congestion pricing and traffic congestion policy, the federal government is, at the same time, handing out large tax breaks to help people reduce the costs of driving to work. It's yet another example of government policy gone awry, badly.

The solution isn't sexy, won't get you on TV, and doesn't make for great headlines that will earn prestige: eliminate all government subsidies, and either cap pollution or tax it. It's not rocket science.
