Researchers assess the risk of species extinction with conservation models that combine factors that drive down populations--including habitat loss, hunting and overfishing--with the probability of chance disasters affecting the group. Even if human activities greatly affect a species, “all populations that go extinct [ultimately] suffer a string of unfortunate random events, such as a fire, that wipe out the last individuals,” says Brett Melbourne, a mathematical ecologist at the University of Colorado at Boulder. Until recently, mathematical models of extinction risk included only two types of randomness. The first--variability in the environment, such as rainfall or temperature changes--impacts birth and death rates across the entire population. The second involves random events affecting select individuals within a group. Siblings may have the same probability of dying in a given year, for example, but only one may be lost to, say, an accidental drowning or other chance event.

Both of Earth's polar environments host rich webs of plants and animals--and all of these inhabitants face a changing clime. [More]

A UK jury has decided that breaking the law and causing large scale criminal is justifiable in the name of climate change alarmism. Here is how The Independent reported it: The threat of global warming is so great that campaigners werejustified in causing more than £35,000 worth of damage to a coal-firedpower station, a jury decided yesterday. In a verdict that will haveshocked ministers and energy companies the jury at Maidstone CrownCourt cleared six Greenpeace activists of criminal damage. Jurorsaccepted defence arguments that the six had a "lawful excuse" to damageproperty at Kingsnorth power station in Kent to prevent even greaterdamage caused by climate change. The defence of "lawful excuse" underthe Criminal Damage Act 1971 allows damage to be caused to property toprevent even greater damage – such as breaking down the door of aburning house to tackle a fire. The not-guilty verdict, deliveredafter two days and greeted with cheers in the courtroom, raises thestakes for the most pressing issue on Britain's green agenda and couldencourage further direct action. Of course, this is only one idiot jury. But it can set a precedent unless the legal authorities determine to overturn it at law. Let us hope EOn has the sense to appeal.  More than that. Let us hope that these Greenepeace anarchists don't find out where we live as, it seems we in the UK who do not subscribe to alarmist GW theory, may be in real danger of seeing our houses and cars vandalised - without legal redress.  For the record . I have written a peace which sets out the opposite case and showing plainly why a coal-fired Kingsnorth should get the go ahead and drawing the analogy with a massive coal-fired plant in Western India given the go aherad because it will drag around 16 million out of abject poverty. Therein lies the bigger human picture. One version is due to appear in the magazine Energy Tribune (fo whom I am a features writer) in October or November. Another is sitting with an editor in a British magazine (so don't hold your breath for that one. ) US Old Farmers Almaanac 2009 Predicts Colder Winter - And Global Cooling Of course, it is not just the popular science and mass media that is hot on prophetic insight (if lousy on facts) but The Old Farmers Almanac -- which at least has a real stake in knowing -- predicts too.

Technology policy lies at the core of the climate change challenge. Even with a cutback in wasteful energy spending, our current technologies cannot support both a decline in carbon dioxide emissions and an expanding global economy. If we try to restrain emissions without a fundamentally new set of technologies, we will end up stifling economic growth, including the development prospects for billions of people. The key is new low-carbon technology, not simply energy efficiency. [More] Green Buildings May Be Cheapest Way to Slow Global Warming North American homes, offices and other buildings contribute an estimated 2.2 billion tons of carbon dioxide to the atmosphere every year--more than one third of the continent's greenhouse gas pollution output. Simply constructing more energy-efficient buildings--and upgrading the insulation and windows in the existing ones--could save a whopping 1.7 billion tons annually, says a new report from the Montreal-based Commission for Environmental Cooperation (CEC), an international organization established by Canada, Mexico and the U.S. under the North American Free Trade Agreement to address continent-wide environmental issues.

You might assume that Chicago dislikes environmentalists, judging by the response they get along Michigan Avenue. They loiter on its crowded sidewalks, trying to stop people with the brightness of their T-shirts, the authority of their clipboards and the innocence of their question: “Do you have a minute to save the earth?” Almost no passerby has that minute, let alone $20 to donate to the cause. What most people have is a scowl, a dismissive wave of the hand and the accelerating stride of a running back. In a city synonymous with Al Capone, do-gooder appeals are about as practical as a citizen’s arrest. But although 2.8 million residents of Chicago may scoff at the notion that noble intentions can stop climate change, that doesn’t mean they think the problem can’t be solved. The city’s leaders know that to get people to save the earth, you must appeal to their bank accounts, not just their consciences. And those leaders are putting their reputation on the line to prove it. [More] Cap and Dividend, Not Trade: Making Polluters Pay If you tried to dump harmful waste on the property next door, your neighbor would either stop you or require you to pay a fee. But if you dump carbon dioxide into the air, no one charges you a penny because no one, as yet, owns the air. This free ride results in what economists call a market failure. The actual costs of polluting the atmosphere are enormous, but polluters don’t pay them. Instead future generations are stuck with the tab. A carbon tax, or a carbon cap-and-trade system, can fix this market failure, but because American politicians are loath to impose taxes, a cap is far more likely. Under a cap, government sets a limit on total carbon emissions and issues tradable permits up to the limit. Each year the number of permits declines, reducing emissions over time. Permits can be issued to companies that emit carbon dioxide or to those that supply it for burning--oil, coal and natural gas firms. Issuing permits to suppliers is easier to administer because no smokestacks need to be monitored. [More]

The past year has been both tempestuous and exciting--from pet food, E. coli and toy poisoning scares to political fireworks over embryonic stem cell research to forest fires ravaging California. A controversial Nobel scientist (James Watson) went down in a blaze of infamy, tumbling from grace after putting his foot in his mouth one time too many, whereas a former vice president and defeated presidential candidate (Al Gore) rose from the ashes to become a Nobel Peace prize (and Oscar) winner for raising awareness on the urgency of global warming. The honor came on the heels of official worldwide recognition that climate change is not only a pressing problem, but one that was almost completely caused by humans--and one, too, that humans must fix. On a related note, we discovered that the North Pole is melting, beloved freshwater dolphins are practically extinct and nuclear power--feared since the 1979 near-meltdown of the Three Mile Island nuke plant in Middletown, Pa.--has become the clean-energy alternative du jour that even has the backing of some enviros. For the first time, too, we enjoyed (depending on how you look at it) an extra month of daylight saving time, thanks to Congress, which made the move to save energy and, lawmakers said, to cut down on traffic accidents--and, perhaps most important, to make Halloween more special and safe.

The Colorado River, the life vein of the Southwestern United States, is in trouble. The river's water is hoarded the moment it trickles out of the mountains of Wyoming and Colorado and begins its 1,450-mile journey to Mexico's border. It runs south through seven states and the Grand Canyon, delivering water to Phoenix, Los Angeles and San Diego. Along the way, it powers homes for 3 million people, nourishes 15 percent of the nation's crops and provides drinking water to one in 12 Americans.

The U.S. government--and major U.S. banks--seem to have lost their appetite for coal. After spending five years and approximately $50 million on preliminary studies as well as selecting a proposed site in Mattoon, Ill., the U.S. Department of Energy (DOE) has scuttled plans to build the so-called FutureGen power plant. The facility would have captured the greenhouse gas carbon dioxide (CO2) that is emitted when coal is burned for electricity generation. Instead, the DOE hopes to help industry add carbon-capture-and-storage capability to advanced coal plants already in the works. "This restructured FutureGen approach is an all-around better investment for Americans," Energy Secretary Samuel Bodman said in a statement announcing the change. The DOE is asking Congress for $407 million to research how to burn coal most efficiently, along with $241 million to demonstrate such carbon capture and storage (CCS) technologies--at least $900 million less than DOE said it would have cost to complete FutureGen.

For the past three years, botanist Vicki Funk of the Smithsonian Institution has been trying, unsuccessfully, to transfer select leaf specimens from Brazil to the U.S. National Herbarium for identification. Comparing closely related plants “is the bread and butter of systematics,” she explains. “We need stuff from other places.” But as biodiversity becomes a valuable commodity, developing countries have complicated efforts to collect and analyze biological samples, Funk says: “It doesn’t matter if you’re an academic, not a drug company. You’re treated the same.” In 1992 the twin goals of the United Nations Convention on Biological Diversity, signed by more than 150 countries, were to preserve biodiversity and to ensure tropical nations were compensated for any “genetic resources” leading to drug discoveries for developed nations. But even as those goals were reaffirmed at a conference held this past spring in Bonn, Germany, scientists continue to criticize policies stemming from the convention. The claim is that the international agreement, which gave countries ownership of plants and animals inside their borders, is hindering tropical research and conservation, not facilitating them. [More] Genetically Modified Hawaii Just beyond the defunct Koloa Sugar Mill on the Hawaiian island of Kauai's south shore are acres of cornfields that have sprouted over the past decade in a state made famous by its pineapples, bananas and sugarcane crops. Slightly out of place in the Aloha State, they otherwise look quite conventional, although in fact they are not: The crop is among a bounty of others in the state that are grown from seeds that have been genetically engineered or modified (GM) to produce sturdier plants able to withstand weather and disease as well as thrive in the face of insects and chemicals sprayed on them to kill destructive weeds. In front of one plot of corn stalks is a red and white sign warning, "Danger: pesticides. Keep out." Tacked to it is a list containing 15 chemicals that may have been applied to the crop. In this case, the chemicals circled are the herbicides pendimethalin (brand name: Prowl), dicamba (Banvel) and atrazine, the latter of which is banned in the European Union (E.U.) because of its link to birth defects in frogs that live in groundwater contaminated with it.

Do the environmental and energy crises driving so many of today’s headlines actually represent a unique opportunity for revitalizing the global economy? That is the argument that Pulitzer Prize–winning journalist Thomas L. Friedman advances in his latest book, Hot, Flat, and Crowded: Why We Need a Green Revolution--and How It Can Renew America (Farrar, Straus & Giroux, 2008). Steve Mirsky, a staff editor and writer for Scientific American and host of its Science Talk podcast, spoke with Friedman about his book in August; what follows is adapted from that conversation, which can be heard/read in full here. --The Editors [More] How Obama Can Change Antienvironmental Policies Dear EarthTalk: How can the new Obama administration and/or Congress undo the many antienvironmental actions the Bush administration undertook over the last eight years, including the obstruction of Bill Clinton’s landmark “roadless rule” legislation? -- Ann Lyman, Lake Tahoe, CA [More]

It is said that the Inuit have many words for snow, but when it comes to the Northwest Passage only one type of frozen water matters: multiyear ice. It can slice through the hull of a ship like a knife through butter and it persists in the passage's waters despite unprecedented warming in the Arctic Ocean, thwarting shippers in search of a shortcut between Europe and Asia. The fabled Northwest Passage has made headlines ever since it thawed last year for the first time. For three centuries the quest for an expedited route between the Atlantic and Pacific oceans rivaled today's space race, with European superpowers vying for the prize. Hundreds of sailors and countless expeditions ventured into Canada's Arctic waters, including such naval luminaries as Sir Francis Drake, Captain James Cook and the ill-fated Henry Hudson, who left his name--and lost his life--on the Canadian bay that marks its entrance.
