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.

If anyone ever thought climate sciences were anything but complex, they obviously weren’t looking hard enough. Recent research from prominent UK and Brazilian climate scientists have found a link between reducing sulphur dioxide emissions from burning coal, and the increase in sea surface temperatures in the tropical north Atlantic, that heightens the risk of drought in the Amazon rainforest.

The Amazon is without a doubt one of the planet’s most valuable and important ecological resources; and not for logging. The rainforest contains approximately one tenth of the total carbon stored in land ecosystems, and recycles much of the rain that falls upon its leafy canopy.

Thus, any major change to its vegetation has massive implications for the global climate system.

There should be a new travel advisory if you are traveling to Africa these days. Not that it has been cutely tucked somewhere in the hundreds of travel advisories issued by the US State Department or EU on terrorism or politically unstable nations of Africa each year.

It is not about biting food shortages either; you’d still blissfully load your favorite McDonald’s double cheeseburger or quarter pounder but take care where you fling away that annoying packaging on your safari.

Speaking of a safari, you’d definitely want to see the wildlife, and that includes some endangered species too. But you may be stung all the way to a crumpled jail house literally if you dare to “disturb” their natural habitat. And this may include doing business too.

My focus in this blog had been on green homes, but there are other areas of our lives that account for our total carbon footprint–how much carbon we are responsible for adding to the atmosphere–a measure of our contribution to global warming. Our houses and apartments, but also our cars, air travel, and the food we eat all contribute.

Asia

Two “Extinct” Species Discovered

First there was Swinshoe’s softshell turtle, and then the Javan Elephant. Is this more commonplace than we might believe?

Frankly, no. Despite the occasional hubbub over an animal science has lost track of– say, the Coelacanth– we’ve witnessed something extraordinary. Swinshoe’s turtle was previously believed to be extinct in the wild, with only three remaining in captivity, and therefore every one of these 300-pound turtles is a critical find.

When you think of Americans who have done a lot for Climate Change, current president George W. Bush doesn’t spring to mind. The guy he beat for the current spot, Al Gore, definitely springs to mind; I like to think of GBW as the anti-Gore.

Over the past week rumors and rumblings about a climate plan underway in the current and fading Whitehouse have emerged. Thankfully, it all seems a bit “disappointing.”

Seventeen nations have come together in Paris for two days in the latest round of climate warming talks, under the heading of the Major Emitters Meeting. The South African delegation was the one to label Bush’s proposals – to halt a rise in U.S. greenhouse gas emissions by 2025 – as disappointing. “There is no way whatever that we can agree to what the U.S. is proposing,” South African Environmental Affairs Minister Marthinus van Schalkwyk said in a statement.

Converting the nation’s vehicle fleet to run on 85% ethanol (Flex-Fuel) may have gotten a whole lot easier.

AAMCO, one of the world’s largest chains of automotive service centers, has started an initiative designed to promote environmental sustainability and energy efficiency across the nation.

The Eco-Green Auto Service initiative will certify automotive centers that meet a stringent set of criteria while adding services that cut emissions, improve mileage, and reduce hazardous waste associated with owning a vehicle.

AAMCO is also promoting alternative fuels by installing E85 conversion kits that allow vehicles to run on ethanol blends up to 85%. Their service centers will use kits provided by Flex Fuel US ®, called the FLEX-BOX SMART KIT™, which is the only ethanol conversion kit fleet-certified by the EPA.

Would I put you on? It’s true, algae-based biofuels are being produced from CO2 emitted from smokstacks.

It’s happening through a company called GreenFuel, headquartered in Cambridge, Mass.

GreenFuel has been partnering with Arizona Public Service Company to create biofuels from algae grown using carbon dioxide (CO2) emissions from a power plant. The companies successfully grew algae at APS’ Redhawk natural gas power plant in Arizona, and is moving their tests to a coal-fired power plant at Farmington, NM.

According to a release from APS, algae at Redhawk grew at levels 37 times higher than corn and 140 times higher than soybeans, which are now used to create biofuels.

The top 10 headlines in international environmental news for the week of March 24 - 30.

1. World — Earth Hour 2008

As the clock struck eight in the evening, people across each time zone turned off their lights on March 29. It’s activism en mass and it’s called Earth Hour. The purpose: to inspire people to take action on climate change and to demonstrate that massive and immediate action is possible.

Earth Hour began as a city-wide voluntary blackout in Sydney, Australia, in 2007. This year, they’ve moved the date ahead two days and invited the world to join in. Even Google’s joined in. People from roughly 35 countries participated in this global event, which has become a yearly call to action. Read more: EcoWorldy, CNN.

2. Asia — Japanese Man Crosses Pacific with Wave-Powered Boat

A Japanese man named Kenichi Horie is attempting to be environmentally friendly by boating across the Pacific without sails and without fossil fuels.

How does he do it? With a wave-powered boat. Wave power has been discussed quite a bit recently, with a lot of applications including traditional grid energy generation. However, Kenichi is taking things to the next level by powering his ocean going vehicle with the very thing it bobs atop. Read more: Gas 2.0.

A climate change summit is taking place March 31st-April 4 in Bangkok. Representatives of over 170 countries are meeting to get a draft accord in place for a successor to the Kyoto Protocol which expires in 2012. The deadline to reach a new protocol has been set for a December 2009 meeting in Denmark.

An interim summit held in Japan mid March convened representatives of the world’s top 20 greenhouse gas emitting countries responsible for 80% of the world’s pollution. It appeared that little progress was made. But all countries including the US agreed in Bali that they’d participate in the negotiations to the Kyoto’s successor and that promise was upheld two weeks ago. What was termed a “principle of common but differentiated responsibility” was accepted as a framework for negotiations. In other words, the new pact will bind all countries to various actions.

As if it wasn’t bad enough that particulate matter from diesel exhaust causes a range of respiratory problems including 15,000 premature deaths each year, new research shows that even short-term exposure to nanoparticles found in diesel fumes can affect brain function.

Nanoparticles can travel to the brain via the olfactory nerve, where they could cause an oxidative stress response in the region of the brain critical to information processing.

Researchers placed subjects in a room with either clean air or diesel fumes (similar to a busy street), and used a electro- encephalograph (EEG) to measure brain response. Subjects breathing the sooty air showed a stress response in the brain’s cortex within 30 minutes, which continued even after they left the room.
