May 6 was World Asthma Day. Since car exhaust can lead to asthma as well as global warming, we thought it would be a good day to highlight the importance of not idling your car or truck engine.

What makes idling especially bad for health is that drivers tend to idle in gathering places - by sidewalks, schools, playgrounds, homes, and offices. Breathing in pollution close to the source is more dangerous than farther away.

Take a look at the evidence.

You swap out your light bulbs for energy-efficient ones, keep your house as chilled as a meat locker in winter, bicycle to work, eat little meat and drive a hybrid — yet nagging at you is this thought: Do my small actions make a difference? Author Michael Pollan says they do.

In last week’s Sunday New York Times Magazine (4.20.08), Pollan wrote a provocative essay, “Why Bother? Looking for a few good reasons to go green.” In it, he wrestles with those lurking questions about our everyday choices to stave off global warming. Some excerpts:

Let’s say I do bother, big time. I turn my life upside-down…, but what would be the point when I know full well that halfway around the world there lives my evil twin, some carbon-footprint doppelgänger in Shanghai or Chongqing who has just bought his first car (Chinese car ownership is where ours was back in 1918), is eager to swallow every bite of meat I forswear and who’s positively itching to replace every last pound of CO2 I’m struggling no longer to emit. So what exactly would I have to show for all my trouble?

He looks at the reasons we find for not doing anything: “There are so many stories we can tell ourselves to justify doing nothing,” he writes.

And yet, he resoundingly concludes that those little things are worth the bother.

This is National Public Health Week, and the focus is on the impact of climate change on our nation’s health. Knowing about the risks you face will help you better prepare for the dangers.

Do you have children?
Because they are still developing physically, breathe faster than adults and rely on adults for care, children are more vulnerable. Watch out for:

Heat waves. Infants and children up to four years old are particularly sensitive to heat and also rely on a care-giver to keep them adequately hydrated.
Smog and soot pollution. Because their lungs are still developing, children can suffer irreversible lung damage as adults from breathing unhealthy air when young.
Food- and waterborne diseases. Small children and children living in poverty are at higher risk for falling ill from diseases that climate change will likely exacerbate.
Stress, anxiety, depression or post-traumatic stress disorder after disastrous extreme weather events.

It’s ironic. In many parts of the world, there is no clean drinking water. Here in the U.S., pure, drinkable water flows out of every tap, and yet Americans buy a staggering amount of bottled water. We pay big bucks for it, too - over $15 billion a year.

Worst of all, the bottles are overflowing our landfills, and contribute to global warming.

Earth: The Sequel tells the story of an exciting race that is just beginning — the race to develop low-carbon energy in time to turn our greatest environmental crisis into our greatest economic opportunity.

Many people have expressed surprise that I’d write a book like this about a problem so serious. And global warming is serious. With each passing year, scientists get more and more alarmed at the increase and extent of disturbing impacts. But this book is not about the doom and gloom of global warming. In fact, it’s just the opposite.

Earth: The Sequel is about hope, invention, ingenuity, entrepreneurialism, capital markets, commerce, and profit. These are words that most people don’t think of when they hear the term “global warming,” and they especially don’t expect to hear them coming from me. After all, I’m an environmental lawyer running one of the country’s most respected and influential environmental groups, advocating for good environmental policy.

I wrote this book because, after 20 years of studying global warming and trying to craft solutions to stop it, I know that government policy alone is not the answer. Enacting a hard cap on carbon will play a key supporting role, but the starring role belongs to American commerce.

Last month’s New York Times report on high mercury levels in tuna sushi was certainly cause for concern for serious sushi lovers. (See my previous post Plenty of Safe, Eco-Friendly Fish in the Sea.)

The report might have also made many parents uneasy about the ubiquitous tuna sandwich in their kids’ lunch boxes. Many of us rely on canned tuna for a wholesome, high-protein meal. Once considered a “nuisance food” or “pauper’s food,” today almost half of all American households serve canned tuna monthly. Only shrimp surpasses canned tuna as Americans’ favorite seafood. But does this beloved fish in a can deliver a helping of toxic mercury, too?

Global warming is the most serious environmental threat of our time.

As these facts show, affordable options are available. And America cannot afford to fall behind any more in the race to invent clean, renewable energy sources.

As a marine scientist who has been researching seafood sustainability and health issues for a long time, I’ve known for a while that bluefin tuna not only has high mercury levels but is severely depleted, too.

These magnificent fish are highly prized for their rich, buttery flesh. The global sushi market can’t get enough bluefin, and as a result, exorbitant prices and severe overfishing are driving bluefin tuna to the brink of extinction.

I love sushi as much as the next person, but given its dire population numbers and high mercury levels, maybe its time that we all lay off for a while.

Now making big headlines is a New York Times report that found that much of the bluefin sushi served in upscale New York City restaurants actually exceeds the Food and Drug Administration’s “action level” for mercury. (The threshold is 1 part per million.)

To reiterate: It’s no surprise that bluefin tuna has high levels of mercury – it’s one of the largest and most predatory fish species in the ocean. What is surprising is just how many New York City restaurants are serving the really high-mercury tuna.

In 2008 I pledge to …

1. Replace my conventional light bulbs with energy-efficient ones. One of the simplest things you can do to save energy and pollution is to swap out your old incandescent bulbs for compact fluorescent lights (CFLs). Today’s high-tech bulbs dim, come in decorative shapes and radiate a warm, rosy glow. If you’re not ready for a full-house makeover, start by changing just one light. See our bulb guide for details.

2. Calculate my carbon footprint and see what I can do to reduce it. Do you live in a large apartment building or a small house? Do you drive a hybrid car or a pickup truck? How many times a year do you fly? Taking stock of your habits is the place to start in cutting “carbs”.

3. Make small changes at home. An easy place to start is unplugging your chargers and computers when you’re not using them. Another simple change that pays off: Turn down your thermostat in winter (55 degrees when away or at night) and up in summer (to 85 when away). Wash clothes in warm or cold water, not hot. See more adjustments you can make that add up to energy savings.

All year long we’ve been monitoring developments in climate science, and posting about the important new developments. I thought now would be a good time to look back over 2007 and summarize what we’ve learned.

Here are ten noteworthy science stories we covered in 2007:

1. The Sun is (really, really) not responsible for global warming. This paper wasn’t breaking news, just an extremely thorough review of the science showing why the sun can’t be blamed for global warming. The folks over at RealClimate said it best: “That’s a coffin with so many nails in it already that the hard part is finding a place to hammer in a new one.”

2. American Southwest climate is becoming drier. Global warming has caused a long-term shift in rain patterns. An author of the study said, “You can’t call it a drought anymore, because it’s going over to a drier climate. No one says the Sahara is in drought.”
