Gross said that even though the Chilean earthquake is much smaller than the Sumatran quake, it is predicted to have changed the position of the figure axis by a bit more for two reasons. First, unlike the 2004 Sumatran earthquake, which was located near the equator, the 2010 Chilean earthquake was located in Earth's mid-latitudes, which makes it more effective in shifting Earth's figure axis. Second, the fault responsible for the 2010 Chiliean earthquake dips into Earth at a slightly steeper angle than does the fault responsible for the 2004 Sumatran earthquake. This makes the Chile fault more effective in moving Earth's mass vertically and hence more effective in shifting Earth's figure axis.

"Researchers at the Atmospheric Infrared Sounder (AIRS) instrument on NASA's Aqua spacecraft have given scientists studying carbon dixoide a new tool - daily global measurements of carbon dioxide in our atmosphere. The data shown in the tool includes information gathered during more than 7 years of research on the concentration and distribution of CO2 in our mid-trophosphere - or, 3-7 miles above the Earth's surface - and how that CO2 travels across the globe. The video after the jump shows an animation of the carbon dioxide levels in our atmosphere with the Mauna Loa curve laid over it. The visualization is intense."

"In 2006, Ron Suskind published "The One Percent Doctrine," a book about the U.S. war on terrorists after 9/11. The title was drawn from an assessment by then-Vice President Dick Cheney, who, in the face of concerns that a Pakistani scientist was offering nuclear-weapons expertise to Al Qaeda, reportedly declared: "If there's a 1% chance that Pakistani scientists are helping Al Qaeda build or develop a nuclear weapon, we have to treat it as a certainty in terms of our response." Cheney contended that the U.S. had to confront a very new type of threat: a 'low-probability, high-impact event.' Soon after Suskind's book came out, the legal scholar Cass Sunstein, who then was at the University of Chicago, pointed out that Mr. Cheney seemed to be endorsing the same "precautionary principle" that also animated environmentalists. Sunstein wrote in his blog: "According to the Precautionary Principle, it is appropriate to respond aggressively to low-probability, high-impact events - such as climate change."

">In Latin America and the Caribbean (LAC), the problems associated with climate change are regarded with great apprehension. The Economic Commission for Latin America and the Caribbean (ECLAC), in a report released during the conference, warned that the region could bear one of the heaviest costs of climate change. The organization said that up to 40 percent of the biodiversity of some Latin American nations could be wiped out by 2100 if steps are not taken immediately to control carbon emissions."

"Our ecological footprint - what we take out of the planet - is now 1.3 times the biological capacity of the Earth. In the words of Professor Bob Watson, Defra's chief scientific adviser and former chairman of the Intergovernmental Panel on Climate Change (IPCC), we are in danger of approaching "a point of no return". So the action we take in the... See More next couple of decades will determine whether the stable environment on which human civilization has depended since the last Ice Age 10,000 years ago will continue. "

"The Middlemist's Red exists in only two known locations: a greenhouse in the UK, and a garden in New Zealand. Imported to Britain two hundred years ago from China, back when flowers where a luxury item, it has since been exterminated in its original homeland. The flower is in bloom for the next couple of weeks, and will be the star attraction at the reopening of the Chiswick House, the BBC reports."

From 1950 to 2006 the United Nation Food and Agriculture Agency (FAO) estimated that 12,700 metric tons of fish were caught in the Arctic, giving the impression that the Arctic was a still-pristine ecosystem, remaining underexploited by the world's fisheries. However, a recent study by the University of British Colombia Fisheries Center and Department of Earth and Ocean Sciences throws cold water on this widespread belief. According to the study, published in Polar Biology, the total Arctic catch from 1950 to 2006 is likely to have been nearly a million metric tons, almost 75 times the FAO's official record.

Challenged by strict air-quality rules, dairy farmers face costly changes to generators used to burn methane to produce power. With the intention of using these generators to eliminate methane waste, along with electricity bills, farmers now meet an unexpected consequence- the conversion of methane into electricity produces nitrogen oxides, or NOx. This pollutant exacerbates the state's smog problem. After already spending several hundreds of thousands of dollars on their "dairy digester" systems at the urge of the state, farmers are forced to abide by the state's air quality standards by purchasing expensive additional equipment, or shut down their waste-consuming generators. The San Joaquin Valley Air Pollution Control District's limit of 11 parts per million of NOx for new digester systems works out to equal the emissions of 26 cars for every 1,000 cows, said Frank Mitloehner, an associate professor at UC Davis' department of animal science.

"Benedict, who has already been hailed by some in the environmentalist community as a "Green Pope," is the head of the world's only carbon-neutral sovereign state. Last year, he had solar panels installed on the Vatican's rooftops--now a key source of the state's electricity. Then, he donated enough trees to an eco-restoration project in Hungary to nullify the small nation's carbon output. One of the first speeches given by the Green Pope included a call for Catholics to be 'better stewards of God's creation.'"

"Today, Target became the first major US retailer to stop selling farmed salmon products! Salmon consumption in the United States is a huge market for retailers. Aquaculture (farming fish) is often called the future of the seafood industry, but some types of aquaculture - such as conventional open-net salmon farming - can cause tremendous damage to the environment. Parasite infestations, concentrated fish waste, the uncontrolled spread of genetic material, and the unsustainable use of wild fish to feed farmed animals all pose significant threats to the sanctity of our marine ecosystems."

"The photovoltaic collector field will feature a 5.3-megawatt system, and will include 16,500 PV panels. The university says that once installed, the field will generate 5.5 percent of the campus' electrical power and bring down its energy costs by about 8 percent. Not too shabby. The 5.5 percent figure is an average stretched over the year. On super sunny days, the installation is capable of meeting up to 20 percent of the campus' power needs."

"The number of tigers in India's wild has gone up by 20%, according to the latest tiger census, which has surveyed the whole of India for the first time. The census puts the population of the big cat at 1,706. There were 1,411 tigers at the last count in 2007."

"I believe the green economy is coming. That's not a question of if it's going to happen, it's just when it's going to happen. The sooner the better for me, because the jobs of the future lie in energy independence and cleaning up the environment…. Why can't America have the cleanest air?"

"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."

"Yesterday, Brazilian politicians took a decisive step towards opening the door to massive new Amazon deforestation, by voting in favor of radical changes to the Brazilian Forest Code - the primary legal instrument for protecting the Amazon.  If these changes become law they will let hundreds of forest criminals off the hook, and massively expand the amount of forest under threat from the chainsaws"

"But some positive news from the biggest developing nations--China, India, and Brazil--have encouraged the proceedings. Each has pledged to reduce carbon emissions on some level, and Obama has put forward an emissions reduction target based on the climate bill that passed the House of Representatives last summer. At 17% below 2005 levels, it's hardly what the international community was looking for--but it's progress nonetheless. Most importantly, hope seems to be in the air--real progress can be made in the coming days."

The Environmental Protection Agency said Monday it will investigate the impact of the chemical Bisphenol-A on the U.S. water supply and other parts of the environment. Federal regulators have been ramping up their scrutiny of the controversial plastic-hardener at the behest of scientists and activists who say it can interfere with infant growth and development.

"This analysis is interesting because it highlights our lopsided thinking about climate change. The media tends to focus a lot on solutions like hybrid cars and CFLs, but transportation and energy use are relatively small parts of the problem. The stuff we consume accounts for nearly half of the greenhouse gases in an area like Portland. And of that, it's the extraction of raw materials and the manufacturing processes for consumer goods that are the biggest culprits. (Food and long-distance freight are second and third.)"

A new study shows that ice melts far more extensively at the base of the Antarctic ice sheet, miles below the surface, than scientists had thought. The findings raise the possibility that melt water may even help govern the behavior of glaciers.

"The woodlands and pastures of southern Spain once provided fertile hunting ground for the Iberian lynx, but habitat destruction, loss of prey, and trapping diminished the population of the reclusive feline dramatically, to just 100 animals a decade ago, making it the most endangered cat in the world. Now, thanks to a combination of political action, high-tech monitoring, and improved public awareness, the lynx is making a slow, if not always steady, comeback in Andalusia."
