April Environmental News Review


Here is a selection of the leading new stories on environmental topics from the month of April. As always, we welcome your comments.

McCain, Clinton support summer gas-tax rollback — Grist.org–April 29, 2008

U.S. presidential candidates Hillary Clinton and John McCain have said they support temporarily suspending the federal excise tax on gasoline and diesel fuel over the summer to ease the impacts of high fuel prices on consumers. McCain indicated he would shift revenue from other sources to cover the estimated $9 billion dip in highway infrastructure funds that would result; Clinton has proposed enacting a windfall-profits tax on oil companies to make up the shortfall. Both Clinton and McCain attacked Barack Obama for opposing the tax suspension. 

Artic Ice Shelf Seen Melting Faster Than Anticipated — Reuters– April 24, 2008

Arctic ice may be melting faster than most climate change science has concluded, the conservation group WWF said in a report published on Thursday. It found that ice in Greenland and across the Arctic region was retreating “at rates significantly faster than predicted in previous expert assessments.”

Security Risk from Climate Said Underestimated — Reuters– April 23, 2008

Countries around the world have hugely underestimated the potential conflicts stemming from climate change and must invest heavily to correct that mistake, a report said on Wednesday. The report for Britain’s Royal United Services Institute (RUSI) by environment expert Nick Mabey said the response had been “slow and inadequate” and to rectify it spending needed to surge to levels comparable to sums spent on counter-terrorism.

Treading Lighter with Low Carbon Diets — Los Angeles Times — April 22, 2008

Conscientious consumers who want to tread lightly are increasingly concerned about their own carbon footprints. They’ve changed lightbulbs. They covet a Prius more than a Porsche. Now their anxiety over global warming has shifted to the supermarket and dinner table. The global food and agriculture system produces about one-third of humanity’s contribution to greenhouse gases. So questions about food are shifting from the familiar “Is this good for me?” or “Will it make me fat?” to “Is it good for the planet?”

Bee Colonies Continue to Decline — The Alternative Consumer– April 21, 2008

Honey bee population declines continue to trouble the U.S. agricultural industry. America’s honey bees are responsible for pollinating more than 100 different crops worth $15 billion annually and continue to experience population decreases as evidenced by a study commissioned by Apiary Inspectors of America, (AIA).

Bush Calls for Flat US Greenhouse Emissions by 2025 — New York Times Dot Earth– April 16, 2008

President Bush, in a Rose Garden speech on climate change, challenged the world’s biggest (and most polluting) countries to immediately end trade barriers on energy-related technology, beef up a fund to help bring less-polluting energy options to poor countries, and commit to curbing their greenhouse-gas emissions.

Bush’s Climate Speech: Too Little Too Late — World Wildlife Fund– April 16, 2008

Dr. Richard Moss, Vice President and Managing Director of Climate Change for the World Wildlife Fund (WWF), and member of the U.N. Intergovernmental Panel on Climate Change, issued the following statement today in response to President Bush’s speech on climate change:

President Bush is not offering a realistic policy proposal. His plan is so lacking in substance, it seems designed only to undercut efforts in Congress and at the international level to reduce climate emissions. 

Agriculture: The Need for Change — United Nations Environment Programme– April 15, 2008

The way the world grows its food will have to change radically to better serve the poor and hungry if the world is to cope with a growing population and climate change while avoiding social breakdown and environmental collapse. That is the message from the report of the International Assessment of Agricultural Science and Technology for Development, a major new report by over 400 scientists which is launched today. The assessment was considered by 64 governments at an intergovernmental plenary in Johannesburg last week.

Climate Change Rises on World Bank Agenda — Reuters– April 10, 2008

Climate change is now one of the World Bank’s top concerns because of its expected impact on health and economic growth in developing countries, the bank’s lead environmental economist said. Latin America, Sub-Saharan Africa and Asia are where global warming’s damage will disproportionately be felt, and that makes it a key issue for the World Bank and other financial institutions aiming to foster development, said Kirk Hamilton, co-author of the Global Monitoring Report.

Combining the highest levels of luxury and sustainable development with beautiful locations, Natural Retreats offer a chance to explore beautiful national parks, bask in luxury, and feel confident that your holiday has a low environmental impact. Built with sustainability in mind, these eco-getaways can be found within four of the UK national parks, with plans to acquire sites in, or alongside, ten more. At current, green-minded travelers can escape to Yorkshire Dales, Snowdonia, Lake District, and North York Moors - all beautiful landscapes and perfect settings for an eco-friendly nature retreat.

Terry Kenney photoWhile the Japanese are trying to produce electricity from train station gates (!?), entrepreneur Terry Kenney is going after a bigger target: Trucks. It took him eight years to get a working prototype, but now there’s one working at the Port of Oakland which Kenney calls the “Dragon Power Station”. Special plates are set on the road, and as big trucks drive over them (about 2,500 of them per day at the port), they compress a tank of hydraulic fluid under the road, which in turn creates a series of pumping actions that turns a generator to produce electricity….

Portland Cyclists photoCongrats Portland! The city just became the first major U.S. city to be designated as a Platinum-level Bicycle Friendly Community by the League of American Bicyclists. The only other city to reach that level in the U.S. is Davis, California, but it only has a population of 63,000, so the challenge wasn’t quite the same (not to take anything away from their accomplishment - kudos to them!). “Portland earned the Gold designation back in 2003 and has been working to achieve Platinum for well over two years. Back in February of 2006, Commissione…

“What’s the advantage…really…of having a solar-powered airplane?”

That’s the kind of question I expect from people who are not immediately enamored with anything powered directly from that great flaming ball in the sky. And I suppose it’s a question that should be answered, while I sit here drooling over the fact that it exists at all.

But the DoD has now answered that question. After a lot of work funding unmanned solar powered aircraft, they’ve announced a plan (Project Vulture!) to create one that will only need to land once every five years. It’s a little bit like a spy satellite, except it can operate under its own power, and at much lower altitudes (though still in the stratosphere).

We’ve seen a few other solar-powered airplanes. Some frikkin’ weird concepts, some to prove that the sun can lift a man off the earth, and at least one to circumnavigate the earth.

The Project Vulture contract has been awarded to three companies: Boeing, Lockheed, and Aurora Flight Sciences. Of these, only Aurora has unveiled an actual concept. The Odysseus craft (pictured) remains very mysterious. But it seems as if it can actually fold the craft along two hinges. This might allow it to fly straight, while maximizing exposure to the setting or rising sun.

It will, of course, be entirely carbon-neutral, storing power in batteries during the day, and using them at night. Theoretically, the number of charge-discharge cycles the batteries are capable of should be the limiting factor in the length of the planes flight.

Each of the three segments are actually an independent unit that can fly, take off and land on their own. Once in the air, they link to provide the maximum amount of lift with the minimum amount of energy with a wingspan longer than that of a Boeing 767. If one of the segments is damaged, the other two can operate completely independently.

And, for those of us who are less interested in using green technology for warfare (albeit cold warfare,) Aurora says that the solar plane could also be useful for mobile communications and meteorology as well.
