Scientist urges carbon tax to help climate
June 24, 2008 09:52 AM - Reuters

The U.S. scientist who 20 years ago first told Congress that the Earth's climate was warming said on Monday that urgent action was needed to cut greenhouse gases and proposed a tax on carbon emissions. James Hansen, the director of NASA's Goddard Institute for Space Studies, said at a congressional briefing that a carbon tax would be the most efficient way to cut global warming emissions and encourage non-fossil energy sources.

1988 and 2008: Climate Change Turning Points
June 24, 2008 09:39 AM -

Exactly 20 years have passed since Dr. James E. Hansen of NASA first testified to Congress on June 23, 1988 that global temperatures had risen beyond the range of natural variability. Waiting another 20 years before taking decisive action is not an option.

Technology and climate change

How much computing can mankind afford? That is a question the computer and telecoms industries hate to hear. They do not see themselves in the same dirty league as airlines or carmakers, sources of huge amounts of carbon dioxide, but instead as part of the solution. In a pre-emptive strike, a group of technology firms calling itself the Global eSustainability Initiative (GeSI) has joined the Climate Group, a non-profit environmental club, to examine how information and communications technologies (ICT) affect climate change.

HHO Generators – The Surge Is Working
June 23, 2008 09:25 AM - Green Tech Gazette

I’ve been talking about HHO generators for a few months now. It’s been amazing how many critics have stated boldly and defiantly that HHO generators cannot work due to one math calculation or another. But, this theoretical “cannot work” has flown in the face of practical application. There are throngs of people using hydrogen generators on their cars and trucks right now that swear by the results.

Analysis Shows Drastic Climate Change Near End Of Last Ice Age
June 23, 2008 09:17 AM - University of Colorado at Boulder

Information gleaned from a Greenland ice core by an international science team shows that two huge Northern Hemisphere temperature spikes prior to the close of the last ice age some 11,500 years ago were tied to fundamental shifts in atmospheric circulation. The ice core showed the Northern Hemisphere briefly emerged from the last ice age some 14,700 years ago with a 22-degree-Fahrenheit spike in just 50 years, then plunged back into icy conditions before abruptly warming again about 11,700 years ago.

Credibility Gap: Toxic Chemicals in Food Packaging and DuPont's Greenwashing
June 20, 2008 11:58 AM - , Organic Consumers Association

In 2006, under pressure from the U.S. EPA, DuPont and 7 other companies promised to phase out by 2015 a cancer-causing chemical called PFOA, used to make Teflon and also found in grease-resistant coatings for food packaging. In its place, the chemical industry is pushing new, supposedly “green” food package coatings.

Smart Technology could reduce global emissions by 15 per cent
June 20, 2008 10:39 AM - United Nations Environment Programme

Transformation in the way people and businesses use technology could reduce annual man-made global emissions by 15 per cent by 2020 and deliver energy efficiency savings to global businesses of over EUR 500 billion(GBP400billion/USD 800 billion), according to a new report published today by independent non-profit The Climate Group and the Global e-Sustainability Initiative (GeSI).

Whales set to chase shrinking feed zones

Endangered migratory whales will be faced with shrinking crucial Antarctic foraging zones which will contain less food and will be further away, a new analysis of the impacts of climate change on Southern Ocean whales has found.

Warming temperatures dangerously pushing bird migrations ever forward.
June 20, 2008 10:12 AM - Wiley-Blackwell

Being slow to change in response to warming temperatures could have serious repercussions for long-distance migrant birds. Many birds are arriving earlier each spring as temperatures warm along the East Coast of the United States. However, the farther those birds journey, the less likely they are to keep pace with the rapidly changing climate.

Ocean satellite launch critical to Australian science
June 20, 2008 10:04 AM - CSIRO Australia

"There's plenty resting on this satellite in terms of where our ocean and climate science is going," says Dr David Griffin, an oceanographer from the CSIRO Wealth from Oceans National Research Flagship and a member of the international Science Team which advises on satellite altimeter missions.
