"Google.org demonstrated a new platform on Thursday that, if implemented in conjunction with a proposed United Nations program, could provide a significant tool to combat climate change. Its new "high-performance satellite imagery-processing engine" can process terabytes of information on thousands of Google servers while giving access to the results online. The platform, which was demonstrated on Thursday at the International Climate Change Conference in Copenhagen, would allow anyone using the tool to monitor whether or not trees were being chopped down in a given forest. It analyzes satellite images to show forest changes over a given time period."

"However, with increasing development pressure, market-based incentives are needed to ensure that private forests remain as forests." WRI officials hope the new online resource will illustrate the history of these forests, and help landowners better understand how numerous forces are affecting the region.

"We know, for example, that Portland has actually reduced its aggregate carbon emissions since 1990 despite growing 18 percent in population, largely due to land-use and transportation strategies that stress infill locations, walkable neighborhoods, and transit-oriented development."

"Most of the chemical absorption of sound occurs at relatively low frequencies, from about 1,000 to 5,000 hertz. Propeller noise ... fall in the same range, as does some military and research sonar. So this "background" noise, especially prevalent near shipping lanes, will be louder. That may be bad news for marine mammals, which use sounds in the same range for communication and echolocation while foraging. "We're not saying that during the next 100 years all dolphins will be deafened," Dr. Zeebe said. "But the background noise could essentially override or mask the sounds that they're depending on."

Cool Green Science: The Conservation Blog of The Nature Conservancy - A blog on conservation, from migratory birds to coral reefs, from rainforests to climate change to personal green technology.

It's said that information is power but could information mean less power, when it comes to electricity use? Environmentalists and makers of so-called smart meters are convinced that's the case. They say if consumers could see in real time how much power they're using, they'd conserve more. But some behavioral economists say no way. They say electricity is so cheap that real-time information might lead people to run their lights and gadgets even more.

As the world weighs how to deal with warming, the idea of human manipulation of climate systems is gaining attention.  Yet beyond the environmental and technical questions looms a more practical issue: How could governments really commit to supervising geoengineering schemes for centuries?

"There are only about 3,200 tigers left on the planet. Habitat loss and illegal pouching are largely to blame. In the last 100 years, world tiger populations have been decimated by 95% due to the demand for tiger bones, skins & other body parts."

"Eight years ago, world governments made a pledge to put a halt to growing biodiversity loss by 2010. They have not succeeded. The ongoing loss of biodiversity has instead become even more severe of a threat to the planet's once-balanced ecosystems--it's become a full-on extinction crisis. Thanks to human development and expansion, species are now going extinct exponentially faster than ever before--they're dying out at the frightening speed of 1,000 times the natural rate."

A rare brown panda!

"Or it could be an ecological disaster, as introducing one species to combat another species often turns out to be. However, after a "detailed" study, scientists are looking at using tiny parasitic wasps as a natural solution to pesticide to protect crops."

"The first decade of the twenty-first century was the hottest since record keeping began in 1880. With an average global temperature of 14.52 degrees Celsius (58.1 degrees Fahrenheit), this decade was 0.2 degrees Celsius (0.36 degrees Fahrenheit) warmer than any previous decade. The year 2005 was the hottest on record, while 2007 and 2009 tied for second hottest. In fact, 9 of the 10 warmest years on record occurred in the past decade."

Conservationists called the 13-nation agreement an important step in protecting the wild cats, whose numbers have plummeted in recent decades as human encroachment has eliminated more than nine-tenths of their habitat. Experts say there are fewer than 3,500 wild tigers today, compared to an estimated 100,000 at the beginning of the 20th century. Hailing the agreement, Michael Baltzer, head of the WWF Tiger Initiative, said "There never has been a high-level government commitment to take forward tiger conservation."

"Globally, two million tons of sewage, industrial and agricultural waste is discharged to the world's waterways."

"We saw no evidence of any deliberate scientific malpractice in any of the work of the Climatic Research Unit and had it been there we believe that it is likely that we would have detected it. Rather we found a small group of dedicated if slightly disorganized researchers who were ill-prepared for being the focus of public attention. As with many small research groups their internal procedures were rather informal."

"Coral reefs are dying, and scientists and governments around the world are contemplating what will happen if they disappear altogether. The idea positively scares them."
