NASA Sees Arctic Ocean Circulation Do an About-Face
November 15, 2007 09:32 AM - NASA - JPL
PASADENA, Calif. – A team of NASA and university scientists has detected an ongoing reversal in Arctic Ocean circulation triggered by atmospheric circulation changes that vary on decade-long time scales. The results suggest not all the large changes seen in Arctic climate in recent years are a result of long-term trends associated with global warming.
OPEC Must Tackle Climate Change: U.N. Official
November 15, 2007 09:20 AM - Reuters
RIYADH (Reuters) - OPEC oil exporters must take climate change seriously at a summit meeting this week, ahead of a key meeting to tackle global warming in Bali next month. a leading U.N. climate change official said on Thursday.
"I encourage OPEC to contribute to climate change abatement and to play an important role in history to drive forward sound solutions to a global problem," Yvo de Boer, executive secretary of the United Nations Framework Convention on Climate Change, told an OPEC forum in the Saudi capital.
German Carmakers Lag France, Italy in CO2 Cuts: Group
November 15, 2007 09:03 AM - Reuters
STRASBOURG, France (Reuters) - Average carbon dioxide (CO2) emissions from new cars made by German manufacturers rose in 2006, while French and Italian producers cut pollution from their vehicles, data showed on Thursday.
Brussels-based environmental group Transport & Environment (T&E) said average emissions from new German vehicles jumped 0.6 percent last year because Germany was producing heavier cars, while French and Italian manufacturers cut emissions from their new cars by 1.6 percent on average.
Greenpeace Blocks Shipment of Indonesian Palm Oil
November 15, 2007 08:35 AM - Reuters
JAKARTA (Reuters) - Greenpeace has blocked a tanker carrying more than 30,000 tonnes of palm oil from leaving an Indonesian port to protest against forest destruction blamed on plantations, the environmental group said on Thursday.
The protest came less than three weeks before a U.N. climate change meeting on the resort island of Bali, where delegates from 189 countries will debate ways to slow down global warming, including the impact of dwindling tropical rainforests.
Greenpeace says shuts down Australia power station

"Climate activists have taken non-violent direct action to shut down the power station ... by locking onto the conveyor system and preventing coal from feeding the plant," Greenpeace Head of Campaigns Steve Campbell said in a statement.
U.N. Completes Carbon Trading Link Under Kyoto
November 14, 2007 01:49 PM - Reuters
LONDON (Reuters) - Japan on Wednesday became the first country to take delivery of carbon offsets which it can use to help it stay within its binding greenhouse gas emissions limits under the Kyoto Protocol, the U.N. climate body said.
Island Nations Plan for Rising Seas, Mass Migration
November 14, 2007 08:33 AM - Ajay Makan -Reuters
Countries usually evacuate their citizens because of war or a sudden and catastrophic natural disaster.
For the Pacific island state of Kiribati, the climate change disaster facing the nation is no less dramatic but on a slower time scale and means preparing its 100,000 inhabitants for lives in nations less vulnerable to wild weather and rising seas.
Palm oil: Cooking the Climate
November 13, 2007 08:33 AM - Greenpeace US
If, as you read this, you're eating a KitKat or reaching into a tube of Pringles, you might be interested to know that these products contain palm oil that is linked to the destruction of forests and peatlands in Indonesia. As our new report "How the palm oil industry is cooking the climate" shows, it's a recipe for disaster.
The manufacturers of these products - Nestlé, Procter & Gamble, and Unilever - are sourcing their palm oil from suppliers who aren't picky about where they site their plantations. As the volunteers at the Forest Defenders Camp in Sumatra have seen, this includes tearing up areas of pristine forest then draining and burning the peatlands.
Clean, carbon-neutral hydrogen on the horizon
November 13, 2007 08:22 AM - Penn State
Hydrogen as an everyday, environmentally friendly fuel source may be closer than we think, according to Penn State researchers.
"The energy focus is currently on ethanol as a fuel, but economical ethanol from cellulose is 10 years down the road," says Bruce E. Logan, the Kappe professor of environmental engineering. "First you need to break cellulose down to sugars and then bacteria can convert them to ethanol."
Waste Water Plus Bacteria Make Hydrogen Fuel: Study
November 12, 2007 06:20 PM - By Deborah Zabarenko, Environment Correspondent, Reuters
WASHINGTON (Reuters) - Bacteria that feed on vinegar and waste water zapped with a shot of electricity could produce a clean hydrogen fuel to power vehicles that now run on petroleum, researchers reported on Monday.
These so-called microbial fuel cells can turn almost any biodegradable organic material into zero-emission hydrogen gas fuel, said Bruce Logan of Penn State University.
This would be an environmental advantage over the current generation of hydrogen-powered cars, where the hydrogen is most commonly made from fossil fuels. Even though the cars themselves emit no climate-warming greenhouse gases, the manufacture of their fuel does.
