Ozone Shuts Down Immune Response

We already know that exposure to ozone, a major component of urban air pollution, increases cardiovascular and pulmonary hospitalizations, and deaths. Now Duke University Medical Center finds that inhaled pollutants impair the immune system, making mice, at least, more susceptible to subsequent foreign invaders, such as bacteria. This just as the Environmental Protection Agency is reviewing the standards for levels of ozone in the air. The current standard is 85 parts per billion. Many medical groups, including the American Thoracic Society, recommend a stricter standard of 60 parts per billion.

(BTW, have I mentioned that we should build a memorial the size of Kansas to all the lab rodents who've unwilling sacrificed themselves so you and I can get fat, do no exercise, make pollution, and still live to 90? I'm thinking a giant white, faux Swiss cheese rat, inscribed with the names all the little lab pets were never given. You and I can write them in with Sharpies.)

Thought we were done with this problem? A new study from Britain finds that the acid rain pollution of the 1970s and 1980s is still largely with us. Action taken over the last 20 years across Europe to clean up acid pollutants (from power generation and industry) in rivers has fallen far short of expectations. Apparently the problem is more stubborn than we'd imagined (read why it's even more stubborn in the U.S). Recent studies in Galloway, the Scottish Highlands and Wales reveal that many streams are still highly acidified. Biological recovery has been particularly poor, with more than two thirds of all streams sampled still acid enough during high flow to cause biological damage, and with metals at toxic concentrations. . . Oops. Further proof that the not-paying-attention thing never really works.—Julia Whitty is Mother Jones' environmental correspondent.

Hey, it's working. The long slumber is coming to an end. A Yale University survey found 40 percent of Americans will only vote for a presidential candidate who has a strong sense of urgency on the global warming problem.

"One of the most surprising findings was the growing sense of urgency," said Anthony Leiserowitz, director of the Yale Project on Climate Change and the study's principal investigator. "Nearly half of Americans now believe that global warming is either already having dangerous impacts on people around the world or will in the next 10 years—a 20-percentage-point increase since 2004. These results indicate a sea change in public opinion."

The survey's findings reveals that 62% of Americans believe life on earth will continue without major disruptions only if society takes immediate and drastic action to reduce global warming; 68% support a new international treaty requiring the U.S. to cut its emissions of carbon dioxide 90% by 2050; 85% support forcing automakers to increase the fuel efficiency of cars, trucks and SUVs to 35 miles per gallon, even if it meant a new car would cost up to $500 more; 82% support requiring electric utilities to produce at least 20% of their electricity from renewable energy sources, even if it cost the average household an extra $100 a year; 50% say they are personally worried—15 percent say a great deal—about global warming.

We heard about Leiserowitz's 2004 survey in MoJo's The Thirteenth Tipping Point. Well, it seems to be tipping, at last. Somebody set the alarm and wake up Washington.—Julia Whitty is Mother Jones' environmental correspondent. You can read from her new book, "The Fragile Edge," and other writings, here.

How To Save 375 Million Gallons Of Gas A Year

Amazingly, American cities did it last year. Did the economy collapse? Did the world end? Nope. The way forward just got a little easier to navigate. So reports the U.S. Department of Energy's National Renewable Energy Laboratory. The work was done by Clean Cities, a network of approximately 90 volunteer coalitions developing public/private partnerships to promote alternative and advanced vehicles, fuel blends, fuel economy, hybrid vehicles, and idle reduction.

According to the report: Seventy-one percent of the 2006 gasoline displacement came from the use of alternative fuels. Thirty percent of that was from the use of compressed natural gas, mostly in heavy-duty vehicles. E85, a blend of 85 percent ethanol and 15 percent gasoline, accounted for 24 percent of gasoline displacement. Coalitions acquired nearly 44,000 hybrid electric vehicles in 2006, a 61 percent increase over 2005. HEV use displaced about 9 million gallons of gasoline. Idle reduction efforts displaced 8.4 million gallons, including 1.2 million gallons from truck stop electrification. Almost 2 million gallons were saved by reducing the number of miles traveled.

Okay, so it's not enough to save the world, and it has some built-in problems, say, ethanol. But it shows us how and where to start, and how surprisingly easy it really is when you make up the collective mind. Imagine how the problem might transform into opportunity if the big guns in DC ever get motivated.—Julia Whitty is Mother Jones' environmental correspondent.

Everybody here at Mother Jones is very pleased to announce that David Corn, long-time Washington Editor for The Nation, best-selling author, blogger, and TV commentator has agreed to take the reins of our greatly expanded Washington bureau.

You can read our old school, fully committeed, awesome press release after the jump. (Quick, somebody "leak" it to Romenesko.) But the gist is: David will head up a team of seven reporters and all this firepower in D.C. represents a fundamental change in the way we do business. Better, stronger, faster than before.

Look out D.C.! Oh, and we've also hired Debra Dickerson (author of The End of Blackness) as an on-line columnist and Nick Aster (who built Treehugger and a lot of the Gawker blogs) to head up our web team. Read more after the jump.
