Accidental invention points to end of light bulbs
Regular readers of Treehugger know that they go all ga-ga over LED lighting. So I was surprised not to find a post about this:
An accidental discovery announced this week has taken LED lighting to a new level, suggesting it could soon offer a cheaper, longer-lasting alternative to the traditional light bulb. The miniature breakthrough adds to a growing trend that is likely to eventually make Thomas Edison's bright invention obsolete.
Read the short article over at LiveScience.com to learn about the science behind the accident. On why this is of interest to enviros:
LEDs produce twice as much light as a regular 60 watt bulb and burn for over 50,000 hours. The Department of Energy estimates LED lighting could reduce U.S. energy consumption for lighting by 29 percent by 2025. LEDs don't emit heat, so they're also more energy efficient. And they're much harder to break.

SUVs are about perceived safety, not actual safety
Just noted: this abstract from an article (pdf) in the journal Crime, Media, and Culture:
Driven to extremes: Fear of crime and the rise of the sport utility vehicle in the United States
During the mid-1980s, the sport utility vehicle (SUV) emerged as one of the most popular automobiles in the United States, a trend that continued throughout the 1990s ... Situating the SUV in the context of fear of crime and risk management during the 1980s and 1990s, it is suggested that the SUV's popularity reflects American attitudes toward crime, random violence, and the importance of defended personal space. While consumer attraction to the SUV is typically attributed to two key features -- safety and interior space -- these pragmatic justifications may be viewed as euphemistic. Safety is not road safety but personal safety. Space is not interior cargo space but social space, including the privileged ability to traverse inhospitable terrain to remove oneself from society. (Emphasis added.)This seems somewhat right to me. SUVs aren't particularly safe vehicles to drive. But they feel safe, at least to some drivers. And that mostly has to do with being large and imposing -- or, essentially, with being perceived as a menace. Managing other people's perceptions might be important if the threat is strangers who mean to do you harm. But it's irrelevant -- or, more accurately, dangerous -- if the threat is flipping upside down at 60 mph.
Which makes me wonder if there's any way to convince people that being safe is actually more important than feeling safe. Sometimes I doubt it.

Warming oceans and Hurricane Wilma
In Environmental Science & Technology, Paul Thacker interviews Judith Curry, climatologist and coauthor of a recent paper in Science on the connection between warming oceans and hurricanes. In her work she found -- as did two similar papers published in peer-reviewed journals recently -- that hurricane intensity is increasing, and it's linked to increasing ocean temperatures, and this is true across the globe. She says:
... you can't use hurricanes to prove that there is global warming. What you can do is show an unambiguous link between the increase in hurricane intensity and the warming sea surface temperatures. And if you look for why the sea surface temperatures are warming since the 1970s, you don't have any explanation other than greenhouse warming.
In totally unrelated news, Hurricane Wilma is the most powerful storm in Atlantic history -- it went from fairly mild to the strongest effing storm ever in 18 hours, blowing away the previous record for speed of intensification.
... Keith Blackwell, hurricane researcher at the University of South Alabama's Coastal Weather Research Center in Mobile ... said Wilma's rapid intensification was caused by the warm waters of the northwest Caribbean, which have spawned other extremely powerful storms.
...
"There are so many astounding things about this season," Blackwell said.Wacky.

Cameron, how do you do it?
Looks like Cameron Diaz has had a busy week (but don't all celebs?). After winning an Environmental Media Award for her show Trippin', she surprised a class at Stanford University when she helped lead a lecture on environmentally friendly design with enviro celebrity William McDonough.
Her appearance is part of mtvU's "Stand-In: Who's Coming To Your Class?" which will be premiering on mtvU Uber on Nov. 1st.
What is mtvU Uber you ask? Like Current TV and Participate.net, members of the mtvU community can help shape news and other content by submitting videos online:
"With today's announcement, we are handing over an entire channel online to college students and everyone who wants new music," said Stephen Friedman, GM, mtvU. "mtvU Uber gives them the power to create and program their own channel, and will remain in perpetual beta mode as they experiment and pioneer the digital future."
If you thought Cameron Diaz leading a class on eco-friendly design sounds a little odd, just imagine Marilyn Manson teaching little Johnny and Suzie Arts in Society!

Rebuilding: Mississippi renewal
Everything I've heard about the Mississippi Renewal Forum leads me to believe it is (was, I guess, since it ended this week) a really kick-ass example of exactly what's needed in the Gulf Coast rebuilding effort. Time will tell whether local communities take the advice meted out in the many New Urbanist presentations, but it sounds like everybody, including Gov. Haley Barbour, was impressed. Click around the site a bit -- there's a daily journal and tons of pictures and descriptions from the presentations. Great stuff.

Barringer lets one get by
The New York Times' Felicity Barringer gets dinged by Media Matters for credulously passing on a bit of administration propaganda about the Arctic Refuge. C'mon, Ms. B, you gotta be on your guard with these people.

Readers talk back about vegetarianism and soy
Umbra’s column on the environmental impact of soy vs. that of meat inspired readers of all stripes — OK, mostly the stripes that are anti-soy — to share their opinions. Here’s a sample of the deluge that hit our inbox, and there’s a whole lot more posted in Gristmill, our blog. Dear Editor: What […]

Germany’s environment minister on eschewing nukes
Five years ago, Germany officially decided to shut down all its nuclear plants by 2020. This past May, the second of 19 plants went offline.
Outgoing German environment minister (and member of the Green Party) Jurgen Trittin has a succinct piece on BBC explaining the government's rationale and arguing for seeing the policy through.
Far from being a necessary element in Germany's quest to meet Kyoto targets, he says, "technically speaking, this base-load relic of the past is standing in the way of flexible and intelligent electricity production." Word.

Encyclopedia Brown and the case of the missing map
Not really sure what to make of this. Apparently the government's map of the Arctic Refuge is gone -- poof, vanished. Why on earth, you're wondering, does the government only have one detailed map of the Refuge? I don't know. Why was it sitting behind some file cabinet? You got me. Was it thrown out deliberately or by accident? Nobody knows. Does it matter? Felicity Barringer thinks maybe so:

When It Rainforests, It Pours
Amazon logging damage: now with twice the depressingness You know all that damage logging has done to the Amazon rainforest? It’s not as bad as you thought. It’s twice as bad! Researchers have developed a way to wring far more detail out of satellite photos, a bittersweet accomplishment in light of the results. Turns out […]
