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.

The next generation of riding transit

Riding transit just got way, way, easier. A new website called SpotBus is wildly better than existing online trip planners. For one thing, you can enter destinations like a normal person -- "Ballard," or "Ikea," or "ferry," or whatever -- not some arcane intersection. It's so much faster and more intuitive that it feels like giving up your old gimcrack five-disc CD changer for an iPod.

It only works in the Puget Sound area, but there's no reason something similar couldn't be devised for other regions.

New study links biodiversity loss to economic inequality

It's increasingly well documented that income inequality matters for a variety of reasons: among them, it has negative effects on public health and social capital. So it was interesting to read a recent study from researchers at McGill University in Quebec. They found that income inequality is also linked to biodiversity loss.

Why bicycling is 25 percent better than you thought

Your car's greenhouse-gas emissions are about 25 percent worse than you think.

How so? Well, for each gallon of gas you burn in your engine, there's the climate equivalent of another quarter-gallon or so embedded in your consumption. What that means is this: the gasoline you use didn't just magically appear in your tank -- it was extracted, refined, and transported to your local station. And all that activity released emissions.

It's a curiosity of our energy system (and other systems too, such as our food system), but it's a curiosity that bears closely on our thinking about how to reduce greenhouse-gas emissions. Stay with me for a moment.

It's usually assumed that each gallon of gas releases about 19.5 pounds of CO2 into the sky. (Some quibble, and argue that it's 19.4 or 19.6. But whatever.) Basic physics dictates that a gallon of gasoline combusted will release a more-or-less fixed amount of CO2. But from a public policy perspective, physics isn't the whole story.
