From Newsweek:
Among the phrases you really, really do not want to hear from climate scientists are: "that really shocked us," "we had no idea how bad it was," and "reality is well ahead of the climate models." Yet in speaking to researchers who focus on the Arctic, you hear comments like these so regularly they begin to sound like the thumping refrain from Jaws: annoying harbingers of something that you really, really wish would go away.
Let me deconstruct the phrases above. The "shock" came when the International Polar Year, a global consortium studying the Arctic, froze a small vessel into the sea ice off eastern Siberia in September 2006. Norwegian explorer Fridtjof Nansen had done the same thing a century before, and his Fram, carried by the drifting ice, emerged off eastern Greenland 34 months later. IPY scientists thought their Tara would take 24 to 36 months. But it reached Greenland in just 14 months, stark evidence that the sea ice found a more open, ice-free, and thus faster path westward thanks to Arctic melting.
The loss of Arctic sea ice "is well ahead of" what the Intergovernmental Panel on Climate Change forecast, largely because emissions of carbon dioxide have topped what the panel—which foolishly expected nations to care enough about global warming to do something about it—projected. "The models just aren't keeping up" with the reality of CO2 emissions, says the IPY's David Carlson. Although policymakers hoped climate models would prove to be alarmist, the opposite is true, particularly in the Arctic.
The IPCC may also have been too cautious on Greenland, assuming that the melting of its glaciers would contribute little to sea-level rise. Some studies found that Greenland's glacial streams were surging and surface ice was morphing into liquid lakes, but others made a strong case that those surges and melts were aberrations, not long-term trends. It seemed to be a standoff. More reliable data, however, such as satellite measurements of Greenland's mass, show that it is losing about 52 cubic miles per year and that the melting is accelerating. So while the IPCC projected that sea level would rise 16 inches this century, "now a more likely figure is one meter [39 inches] at the least," says Carlson. "Chest high instead of knee high, with half to two thirds of that due to Greenland." Hence the "no idea how bad it was."
The frozen north had another surprise in store. Scientists have long known that permafrost, if it melted, would release carbon, exacerbating global warming, which would melt more permafrost, which would add more to global warming, on and on in a feedback loop. But estimates of how much carbon is locked into Arctic permafrost were, it turns out, woefully off. "It's about three times as much as was thought, about 1.6 trillion metric tons, which has surprised a lot of people," says Edward Schuur of the University of Florida. "It means the potential for positive feedbacks is greatly increased." That 1.6 trillion tons is about twice the amount now in the atmosphere. And Schuur's measurements of how quickly CO2 can come out of permafrost, reported in May, were also a surprise: 1 billion to 2 billion tons per year. Cars and light trucks in the U.S. emit about 300 million tons per year.
In an insightful observation in The Guardian this month, Jim Watson of the University of Sussex wrote that "a new breed of climate sceptic is becoming more common": someone who doubts not the science but the policy response. Given the pathetic (non)action on global warming at the G8 summit, and the fact that the energy/climate bill passed by the House of Representatives is so full of holes and escape hatches that it has barely a prayer of averting dangerous climate change, skepticism that the world will get its act together seems appropriate. For instance, the G8, led by Europe, has vowed to take steps to keep global warming below 2 degrees Celsius by reducing CO2 emissions. We're now at 0.8 degree. But the amount of CO2 in the atmosphere is already enough to raise the mercury 2 degrees. The only reason it hasn't is that the atmosphere is full of crap (dust and aerosols that contribute to asthma, emphysema, and other diseases) that acts as a global coolant. As that pollution is reduced for health reasons, we're going to blast right through 2 degrees, which is enough to ex-acerbate droughts and storms, wreak havoc on agriculture, and produce a planet warmer than it's been in millions of years. The 2-degree promise is a mirage.
The test of whether the nations of the world care enough to act will come in December, when 192 countries meet in Copenhagen to hammer out a climate treaty. Carlson vows that IPY will finish its Arctic assessment in time for the meeting, and one conclusion is already clear. "A consensus has developed during IPY that the Greenland ice sheet will disappear," he says. Cue

"Scientists Worry Machines May Outsmart Man"
From the New York Times:
A robot that can open doors and find electrical outlets to recharge itself. Computer viruses that no one can stop. Predator drones, which, though still controlled remotely by humans, come close to a machine that can kill autonomously.
Impressed and alarmed by advances in artificial intelligence, a group of computer scientists is debating whether there should be limits on research that might lead to loss of human control over computer-based systems that carry a growing share of society’s workload, from waging war to chatting with customers on the phone.
Their concern is that further advances could create profound social disruptions and even have dangerous consequences.
As examples, the scientists pointed to a number of technologies as diverse as experimental medical systems that interact with patients to simulate empathy, and computer worms and viruses that defy extermination and could thus be said to have reached a “cockroach” stage of machine intelligence.
While the computer scientists agreed that we are a long way from Hal, the computer that took over the spaceship in “2001: A Space Odyssey,” they said there was legitimate concern that technological progress would transform the work force by destroying a widening range of jobs, as well as force humans to learn to live with machines that increasingly copy human behaviors.
The researchers — leading computer scientists, artificial intelligence researchers and roboticists who met at the Asilomar Conference Grounds on Monterey Bay in California — generally discounted the possibility of highly centralized superintelligences and the idea that intelligence might spring spontaneously from the Internet. But they agreed that robots that can kill autonomously are either already here or will be soon.
They focused particular attention on the specter that criminals could exploit artificial intelligence systems as soon as they were developed. What could a criminal do with a speech synthesis system that could masquerade as a human being? What happens if artificial intelligence technology is used to mine personal information from smart phones?
The researchers also discussed possible threats to human jobs, like self-driving cars, software-based personal assistants and service robots in the home. Just last month, a service robot developed by Willow Garage in Silicon Valley proved it could navigate the real world.
A report from the conference, which took place in private on Feb. 25, is to be issued later this year. Some attendees discussed the meeting for the first time with other scientists this month and in interviews.
The conference was organized by the Association for the Advancement of Artificial Intelligence, and in choosing Asilomar for the discussions, the group purposefully evoked a landmark event in the history of science. In 1975, the world’s leading biologists also met at Asilomar to discuss the new ability to reshape life by swapping genetic material among organisms. Concerned about possible biohazards and ethical questions, scientists had halted certain experiments. The conference led to guidelines for recombinant DNA research, enabling experimentation to continue.
The meeting on the future of artificial intelligence was organized by Eric Horvitz, a Microsoft researcher who is now president of the association....

Western Canada Drought
From the Economist:
DURING the Depression of the 1930s, drought turned much of Alberta and Saskatchewan, on Canada’s western prairies, into a dust bowl. The combination of poor harvests and low grain prices drove thousands of farmers off the land. Now some prairie dwellers reckon history is repeating itself. The fall in oil and gas prices from their record highs a year ago has brought an abrupt halt to Alberta’s energy-based boom. And while grain prices have picked up, drought has once again brought billions of dollars of losses to farms and ranches.
A huge swathe of farmland spanning central Saskatchewan and Alberta, and angling northwest into British Columbia’s Peace River valley has suffered its driest winter and spring in at least 50 years (and 70 in some districts). Rainfall has been less than 40% of its normal level. Ranchers are staring at dry water holes and desiccated pasture, forcing them either to sell cattle or buy feed. Farmers are kicking at shrivelled crops. Heavy rains in late June and early July may make some fields worth harvesting but many are already lost. Some 900 farmers around Kindersley, south-west of Saskatoon, have ploughed their crops under and claimed insurance, according to Stewart Wells, the president of Canada’s National Farmers Union. He foresees losses of up to 30% in wheat, barley, rapeseed and hay, and more if the drought continues.
Worse, such conditions may become the norm. David Schindler, an ecologist at the University of Alberta, says that evidence from tree rings and ancient algae suggests that the prairies were drought-prone in the past and that the 20th century was unusually wet. The prairies lie in the eastern rain shadow of the Rocky Mountains. Almost all their rivers flow eastward from the Rockies. As global warming melts mountain glaciers, the rivers’ summer flow has dwindled by up to 60% (more in one case) of their historical average. But more water is being drawn from them for cities, irrigation and the processing of oil from tar sands. Mr Schindler fears that unless these trends are reversed, the prairies risk becoming semi-desert.
Farmers grumble that their margins are so low that a bad year can bankrupt them. Last month their union urged the federal parliament to support family farmers and curb the power of agribusiness corporations. Perhaps prairie populism is on the way back, too.

Texas Drought
(AP) Off-duty police officers are patrolling streets, looking for people illegally watering their lawns and gardens. Residents are encouraged to stealthily rat out water scofflaws on a 24-hour hot line. One Texas lake has dipped so low that stolen cars dumped years ago are peeking up through the waterline.
The nation's most drought-stricken state is deep-frying under relentless 100-degree days and waterways are drying up, especially in the hardest-hit area covering about 350 miles across south-central Texas. That's making folks worried about the water supply — and how long it might last.
"The water table's fallin' and fallin' and fallin,' like a whole lot of other people around here," said Wendell McLeod, general manager of Liberty Hill Water Supply Corp. and a 60-year resident of the town northwest of Austin. "This is the worst I can recall seeing it. I tell you, it's just pretty bleak."
There are 230 Texas public water systems under mandatory water restrictions, including those in and near San Antonio, Dallas, Houston and Austin. Another 60 or so have asked for voluntary cutbacks. Water levels are down significantly in lakes, rivers and wells around Texas.
Liberty Hill's Web site urges its 1,400 or so residents in all-red letters to stop using unnecessary water with this plea: "If we follow these strict guidelines, we may have drinking water." The town's shortage eased some with the arrival this week of 35,000 gallons a day from a nearby water system, but residents are still worried.
According to drought statistics released by the U.S. Department of Agriculture, 77 of Texas' 254 counties are in extreme or exceptional drought, the most severe categories. No other state in the continental U.S. has even one area in those categories. John Nielsen-Gammon, the Texas state climatologist at Texas A&M University, said he expects harsh drought conditions to last at least another month.
In the bone-dry San Antonio-Austin area, the conditions that started in 2007 are being compared to the devastating drought of the 1950s. There have been 36 days of 100 degrees or more this year in an area where it's usually closer to 12.
Among the most obvious problems are the lack of water in Lake Travis and Lake Buchanan near Austin, two massive reservoirs along the Colorado River that provide drinking water for more than 1 million people and also are popular boating and swimming spots. Streams and tributaries that feed the lakes have "all but dried up," according to the Lower Colorado River Authority.
Lake Travis is more empty than full, down 54 percent. All but one of the 12 boating ramps are closed because they no longer reach the water, and the last may go soon. The receding waters have even revealed old stolen cars shoved into the lake years ago, authorities said.

Dean Foods and Silk Soy Milk
From Alternet:
Since Dean Foods acquired Silk it has ditched support of domestic organic farms.
Even as demand for organic food continues to explode, organic farmers in America are getting thrown under the beet cart they helped build.
The Chinese are taking over market share, especially of vegetables and agricultural commodities like soy, thanks to several American-based multinational food corporations that have hijacked the organic bandwagon they only recently jumped onto.
When megacorporation Dean Foods acquired Silk soy milk the prospects looked good for American organic soy farmers. Silk had always been committed to supporting domestic organic farmers, and with the new might of Dean Foods behind it, Silk would likely grow. Silk did grow, but it also dropped its commitment to domestic soy.
Multiple Midwestern farmers and farmers cooperatives in the heart of American soy country were told by Silk they had to match the rock-bottom cost of Chinese organic soybeans -- a price they simply could not meet. Organic agriculture is labor-intensive, and China's edge comes largely from its abundance of cheap labor.
"Dean Foods had the opportunity to push organic and sustainable agriculture to incredible heights of production by working with North American farmers and traders to get more land in organic production," says Merle Kramer, a marketer for the Midwestern Organic Farmers Cooperative, based in Michigan. "But what they did was pit cheap foreign soybeans against the U.S. organic farmer, taking away any attraction for conventional farmers to make the move into sustainable agriculture."
Silk bought Chinese soybeans for years, building a commanding share of the soy milk market, before substantially decreasing its support of organic agriculture altogether.
Few Silk products are certified organic anymore, and some are processed with hexane, a neurotoxin. The use of hexane poses risks to workers in the plants and possibly the consumers of the product and is listed as an air pollutant by EPA. In Illinois alone, 5 million pounds of hexane are released into the environment by food processors Bunge, Cargill and Arthur Daniels Midland.
While the green "USDA Organic" seal is gone, hexane-processed soymilk can still be labeled "natural," and if it contains organic ingredients, the label "made with organic ingredients" is still used.
A recent USDA report, "Emerging Issues in the U.S. Organic Industry," points out two notable trends in American food: Conventional food corporations are taking over successful independent organic companies, and the corporations are becoming increasingly dependent on imported ingredients.

Pesticide linked to Parkinson's disease
From The University of Texas Southwestern Medical Center:
Pesticide levels in blood linked to Parkinson's disease, researchers find
DALLAS — People with Parkinson’s disease have significantly higher blood levels of a particular pesticide than healthy people or those with Alzheimer’s disease, researchers at UT Southwestern Medical Center have found.
In a study appearing in the July issue of Archives of Neurology, researchers found the pesticide beta-HCH (hexachlorocyclohexane) in 76 percent of people with Parkinson’s, compared with 40 percent of healthy controls and 30 percent of those with Alzheimer’s.
The finding might provide the basis for a beta-HCH blood test to identify individuals at risk for developing Parkinson’s disease. The results also point the way to more research on environmental causes of Parkinson’s.
“There’s been a link between pesticide use and Parkinson’s disease for a long time, but never a specific pesticide,” said Dr. Dwight German, professor of psychiatry at UT Southwestern and a senior author of the paper. “This is particularly important because the disease is not diagnosed until after significant nerve damage has occurred. A test for this risk factor might allow for early detection and protective treatment.”
About 1 million people in the U.S. have Parkinson’s, a number expected to rise as the population ages. The disease occurs when brain cells in particular regions die, causing tremors, cognitive problems and a host of other symptoms...
“Much higher levels of the beta-HCH were in the air, water and food chain when the Parkinson’s patients were in their 20s and 30s,” Dr. German said. “Also, the half-life of the pesticide is seven to eight years, so it stays in the body for a long time.”
Parkinson’s disease is more common among rural men than other demographic groups, but it is not a matter of a single factor causing the devastating disease, Dr. German said.
“Some people with Parkinson’s might have the disease because of exposure to environmental pesticides, but there are also genes known to play a role in the condition,” Dr. German said.
Although the current study points to an interesting link between the pesticide beta-HCH and Parkinson’s, there could be other pesticides involved with the disease, he said.
For example, the pesticide lindane often contains beta-HCH, but lindane breaks down faster. Beta-HCH might simply be a sign that someone was exposed to lindane, with lindane actually causing the damage to the brain, the researchers said...

"Iraq Suffers as the Euphrates River Dwindles"
From the New York Times:
JUBAISH, Iraq — Throughout the marshes, the reed gatherers, standing on land they once floated over, cry out to visitors in a passing boat.
“Maaku mai!” they shout, holding up their rusty sickles. “There is no water!”
The Euphrates is drying up. Strangled by the water policies of Iraq’s neighbors, Turkey and Syria; a two-year drought; and years of misuse by Iraq and its farmers, the river is significantly smaller than it was just a few years ago. Some officials worry that it could soon be half of what it is now.
The shrinking of the Euphrates, a river so crucial to the birth of civilization that the Book of Revelation prophesied its drying up as a sign of the end times, has decimated farms along its banks, has left fishermen impoverished and has depleted riverside towns as farmers flee to the cities looking for work.
The poor suffer more acutely, but all strata of society are feeling the effects: sheiks, diplomats and even members of Parliament who retreat to their farms after weeks in Baghdad.
Along the river, rice and wheat fields have turned to baked dirt. Canals have dwindled to shallow streams, and fishing boats sit on dry land. Pumps meant to feed water treatment plants dangle pointlessly over brown puddles.
“The old men say it’s the worst they remember,” said Sayid Diyia, 34, a fisherman in Hindiya, sitting in a riverside cafe full of his idle colleagues. “I’m depending on God’s blessings.”
The drought is widespread in Iraq. The area sown with wheat and barley in the rain-fed north is down roughly 95 percent from the usual, and the date palm and citrus orchards of the east are parched. For two years rainfall has been far below normal, leaving the reservoirs dry, and American officials predict that wheat and barley output will be a little over half of what it was two years ago.
It is a crisis that threatens the roots of Iraq’s identity, not only as the land between two rivers but as a nation that was once the largest exporter of dates in the world, that once supplied German beer with barley and that takes patriotic pride in its expensive Anbar rice.
Now Iraq is importing more and more grain. Farmers along the Euphrates say, with anger and despair, that they may have to abandon Anbar rice for cheaper varieties.
Droughts are not rare in Iraq, though officials say they have been more frequent in recent years. But drought is only part of what is choking the Euphrates and its larger, healthier twin, the Tigris.
The most frequently cited culprits are the Turkish and Syrian governments. Iraq has plenty of water, but it is a downstream country. There are at least seven dams on the Euphrates in Turkey and Syria, according to Iraqi water officials, and with no treaties or agreements, the Iraqi government is reduced to begging its neighbors for water.
At a conference in Baghdad — where participants drank bottled water from Saudi Arabia, a country with a fraction of Iraq’s fresh water — officials spoke of disaster.
“We have a real thirst in Iraq,” said Ali Baban, the minister of planning. “Our agriculture is going to die, our cities are going to wilt, and no state can keep quiet in such a situation.”...
Recently, the Water Ministry announced that Turkey had doubled the water flow into the Euphrates, salvaging the planting phase of the rice season in some areas.
That move increased water flow to about 60 percent of its average, just enough to cover half of the irrigation requirements for the summer rice season. Though Turkey has agreed to keep this up and even increase it, there is no commitment binding the country to do so.
With the Euphrates showing few signs of increasing health, bitterness over Iraq’s water threatens to be a source of tension for months or even years to come between Iraq and its neighbors. Many American, Turkish and even Iraqi officials, disregarding the accusations as election-year posturing, say the real problem lies in Iraq’s own deplorable water management policies.
“There used to be water everywhere,” said Abduredha Joda, 40, sitting in his reed hut on a dry, rocky plot of land outside Karbala. Mr. Joda, who describes his dire circumstances with a tired smile, grew up near Basra but fled to Baghdad when Saddam Hussein drained the great marshes of southern Iraq in retaliation for the 1991 Shiite uprising. He came to Karbala in 2004 to fish and raise water buffaloes in the lush wetlands there that remind him of his home.
“This year it’s just a desert,” he said.
Along the river, there is no shortage of resentment at the Turks and Syrians. But there is also resentment at the Americans, Kurds, Iranians and the Iraqi government, all of whom are blamed. Scarcity makes foes of everyone.
The Sunni areas upriver seem to have enough water, Mr. Joda observed, a comment heavy with implication...
On a scorching morning in Diwaniya, Bashia Mohammed, 60, was working in a drainage pool by the highway gathering salt, her family’s only source of income now that its rice farm has dried up. But the dead farm was not the real crisis.
“There’s no water in the river that we drink from,” she said, referring to a channel that flows from the Euphrates. “It’s now totally dry, and it contains sewage water. They dig wells but sometimes the water just cuts out and we have to drink from the river. All my kids are sick because of the water.”..
"Climate change 'will cause civilisation to collapse'"
From the Independent:
"Authoritative new study sets out a grim vision of shortages and violence – but amid all the gloom, there is some hope too"
By Jonathan Owen
An effort on the scale of the Apollo mission that sent men to the Moon is needed if humanity is to have a fighting chance of surviving the ravages of climate change. The stakes are high, as, without sustainable growth, "billions of people will be condemned to poverty and much of civilisation will collapse".
This is the stark warning from the biggest single report to look at the future of the planet – obtained by The Independent on Sunday ahead of its official publication next month. Backed by a diverse range of leading organisations such as Unesco, the World Bank, the US army and the Rockefeller Foundation, the 2009 State of the Future report runs to 6,700 pages and draws on contributions from 2,700 experts around the globe. Its findings are described by Ban Ki-moon, Secretary-General of the UN, as providing "invaluable insights into the future for the United Nations, its member states, and civil society".
The impact of the global recession is a key theme, with researchers warning that global clean energy, food availability, poverty and the growth of democracy around the world are at "risk of getting worse due to the recession". The report adds: "Too many greedy and deceitful decisions led to a world recession and demonstrated the international interdependence of economics and ethics."
Although the future has been looking better for most of the world over the past 20 years, the global recession has lowered the State of the Future Index for the next 10 years. Half the world could face violence and unrest due to severe unemployment combined with scarce water, food and energy supplies and the cumulative effects of climate change.
And the authors of the report, produced by the Millennium Project – a think-tank formerly part of the World Federation of the United Nations Associations – set out a number of emerging environmental security issues. "The scope and scale of the future effects of climate change – ranging from changes in weather patterns to loss of livelihoods and disappearing states – has unprecedented implications for political and social stability."
But the authors suggest the threats could also provide the potential for a positive future for all. "The good news is that the global financial crisis and climate change planning may be helping humanity to move from its often selfish, self-centred adolescence to a more globally responsible adulthood... Many perceive the current economic disaster as an opportunity to invest in the next generation of greener technologies, to rethink economic and development assumptions, and to put the world on course for a better future."
Scientific and technological progress continues to accelerate. IBM promises a computer at 20,000 trillion calculations per second by 2011, which is estimated to be the speed of the human brain. And nanomedicine may one day rebuild damaged cells atom by atom, using nanobots the size of blood cells. But technological progress carries its own risks. "Globalisation and advanced technology allow fewer people to do more damage and in less time, so that possibly one day a single individual may be able to make and deploy a weapon of mass destruction."
The report also praises the web, which it singles out as "the most powerful force for globalisation, democratisation, economic growth, and education in history". Technological advances are cited as "giving birth to an interdependent humanity that can create and implement global strategies to improve the prospects for humanity"....
The effects of climate change are worsening – by 2025 there could be three billion people without adequate water as the population rises still further. And massive urbanisation, increased encroachment on animal territory, and concentrated livestock production could trigger new pandemics.
Although government and business leaders are responding more seriously to the global environmental situation, it continues to get worse, according to the report. It calls on governments to work to 10-year plans to tackle growing threats to human survival, targeting particularly the US and China, which need to apply the sort of effort and resources that put men on the Moon...

"World at Gunpoint"
"Or, what's wrong with the simplicity movement"
BY DERRICK JENSEN
A FEW MONTHS AGO at a gathering of activist friends someone asked, “If our world is really looking down the barrel of environmental catastrophe, how do I live my life right now?”
The question stuck with me for a few reasons. The first is that it’s the world, not our world. The notion that the world belongs to us—instead of us belonging to the world—is a good part of the problem.
The second is that this is pretty much the only question that’s asked in mainstream media (and even among some environmentalists) about the state of the world and our response to it....
The third and most important reason the question stuck with me is that it’s precisely the wrong question....
The larger problem with the metaphor, and the reason for this new column in Orion, is the question at the end: “how shall I live my life right now?” Let’s take this step by step. We’ve figured out what the gun is: this entire extractive culture that has been deforesting, defishing, dewatering, desoiling, despoiling, destroying since its beginnings. We know this gun has been fired before and has killed many of those we love, from chestnut ermine moths to Carolina parakeets. It’s now aimed (and firing) at even more of those we love, from Siberian tigers to Indian gavials to entire oceans to, in fact, the entire world, which includes you and me. If we make this metaphor real, we might understand why the question—asked more often than almost any other—is so wrong. If someone were rampaging through your home, killing those you love one by one (and, for that matter, en masse), would the question burning a hole in your heart be: how should I live my life right now? I can’t speak for you, but the question I’d be asking is this: how do I disarm or dispatch these psychopaths? How do I stop them using any means necessary?
Finally we get to the point. Those who come after, who inherit whatever’s left of the world once this culture has been stopped—whether through peak oil, economic collapse, ecological collapse, or the efforts of brave women and men fighting in alliance with the natural world—are not going to care how you or I lived our lives. They’re not going to care how hard we tried. They’re not going to care whether we were nice people. They’re not going to care whether we were nonviolent or violent. They’re not going to care whether we grieved the murder of the planet. They’re not going to care whether we were enlightened or not enlightened. They’re not going to care what sorts of excuses we had to not act (e.g., “I’m too stressed to think about it” or “It’s too big and scary” or “I’m too busy” or any of the thousand other excuses we’ve all heard too many times). They’re not going to care how simply we lived. They’re not going to care how pure we were in thought or action. They’re not going to care if we became the change we wished to see.
...They’re going to care whether they can breathe the air and drink the water. They’re going to care whether the land is healthy enough to support them.
We can fantasize all we want about some great turning, and if the people (including the nonhuman people) can’t breathe, it doesn’t matter. Nothing matters but that we stop this culture from killing the planet. It’s embarrassing even to have to say this. The land is the source of everything. If you have no planet, you have no economic system, you have no spirituality, you can’t even ask this question. If you have no planet, nobody can ask questions.
What question would I ask instead? What if, instead of asking “How shall I live my life?” people were to ask the land where they live, the land that supports them, “What can and must I do to become your ally, to help protect you from this culture? What can we do together to stop this culture from killing you?”
----------------
While I get the concepts of the world being at gunpoint, etc. I question his target - the simplicity movement. I also question whether he is actually trying to "stop them using any means necessary". Which suggests violence, etc.
I also don't think that the simplicity movement is the problem. On the contrary - one would think that the simplicity movement - that is the people who identify more or less with that - are doing more than most. Simplicity is the opposite of clueless consumption. Mindfulness is the opposite of cluelessly shooting wolves from planes, etc.
Could everyone be doing more? sure. But I am infinitely happier with people who, when are wondering how to live their lives are choosing to live them better, to grow their own organic food, shop at Goodwill, live with less air conditioning (or none) or whatever - as opposed to people who figure that the way to answer the question "how do I live my life right now?" is to deny there is a problem, to consume as much as they can, and/or to live hedonistically.

NOAA Bans Commercial Harvesting of Krill
NOAA Press Release:
The National Oceanic and Atmospheric Administration (NOAA) today published a final rule in the Federal Register prohibiting the harvesting of krill in the Exclusive Economic Zone (EEZ) off the coasts of California, Oregon, and Washington. The rule goes into effect on August 12, 2009. Krill are a small shrimp-like crustacean and a key source of nutrition in the marine food web.
“Krill are the foundation for a healthy marine ecosystem,” said Mark Helvey, NOAA’s Fisheries Service Southwest Assistant Regional Administrator for Sustainable Fisheries. “Protecting this vital food resource will help protect and maintain marine resources and put federal regulations in line with West-Coast states.”
While the States of California, Oregon and Washington currently have regulations prohibiting the harvesting of krill within three miles of their coastlines, there was no similar federal restriction within the three to 200-mile confines of the EEZ.
The krill prohibition was adopted as Amendment 12 to the Coastal Pelagic Species Fishery Management Plan (FMP), which was developed by the Pacific Fishery Management Council (PFMC) under the Magnuson-Stevens Fishery Conservation and Management Act. The krill harvest prohibition was originally proposed to the PFMC and NOAA Fisheries Service by NOAA’s Office of National Marine Sanctuaries. Today’s rule implements Amendment 12 to the FMP and is intended to preserve key nutritional relationships in the California Current ecosystem, which includes five National Marine Sanctuaries.
"This is a great success for protecting the entire California Current ecosystem", said William Douros, West Coast Regional Director for NOAA's Office of National Marine Sanctuaries. "This decision reflects strong teamwork within NOAA and a commitment to addressing the issues raised by the Pacific Fishery Management Council and Sanctuary Advisory Councils."
Amendment 12 adds all species of krill under a new category, “prohibited harvest species.” This new group may not be caught or taken by any fishery or gear type within the EEZ.
Krill are important because they convert microscopic phytoplankton into a food source for numerous other species and are a principal food source for many species of fish, seabirds and marine mammals. Some of the species that depend on krill as prey are listed as threatened or endangered under the Endangered Species Act, and many others are important as target species for commercial and recreational fisheries on the west coast.

Nitrates, disease and death
Researchers Find Possible Environmental Causes for Alzheimer’s, Diabetes
A new study by researchers at Rhode Island Hospital has found a substantial link between increased levels of nitrates in our environment and food with increased deaths from diseases, including Alzheimer’s, diabetes mellitus and Parkinson’s. The study was published in the Journal of Alzheimer’s Disease (Volume 17:3 July 2009).
Led by Suzanne de la Monte, MD, MPH, of Rhode Island Hospital, researchers studied the trends in mortality rates due to diseases that are associated with aging, such as diabetes, Alzheimer’s, Parkinson’s, diabetes and cerebrovascular disease, as well as HIV. They found strong parallels between age adjusted increases in death rate from Alzheimer’s, Parkinson’s, and diabetes and the progressive increases in human exposure to nitrates, nitrites and nitrosamines through processed and preserved foods as well as fertilizers. Other diseases including HIV-AIDS, cerebrovascular disease, and leukemia did not exhibit those trends. De la Monte and the authors propose that the increase in exposure plays a critical role in the cause, development and effects of the pandemic of these insulin-resistant diseases.
De la Monte, who is also a professor of pathology and lab medicine at The Warren Alpert Medical School of Brown University, says, “We have become a ‘nitrosamine generation.’ In essence, we have moved to a diet that is rich in amines and nitrates, which lead to increased nitrosamine production. We receive increased exposure through the abundant use of nitrate-containing fertilizers for agriculture.” She continues, “Not only do we consume them in processed foods, but they get into our food supply by leeching from the soil and contaminating water supplies used for crop irrigation, food processing and drinking.”
Nitrites and nitrates belong to a class of chemical compounds that have been found to be harmful to humans and animals. More than 90 percent of these compounds that have been tested have been determined to be carcinogenic in various organs. They are found in many food products, including fried bacon, cured meats and cheese products as well as beer and water. Exposure also occurs through manufacturing and processing of rubber and latex products, as well as fertilizers, pesticides and cosmetics.
Nitrosamines are formed by a chemical reaction between nitrites or other proteins. Sodium nitrite is deliberately added to meat and fish to prevent toxin production; it is also used to preserve, color and flavor meats. Ground beef, cured meats and bacon in particular contain abundant amounts of amines due to their high protein content. Because of the significant levels of added nitrates and nitrites, nitrosamines are nearly always detectable in these foods. Nitrosamines are also easily generated under strong acid conditions, such as in the stomach, or at high temperatures associated with frying or flame broiling. Reducing sodium nitrite content reduces nitrosamine formation in foods.
Nitrosamines basically become highly reactive at the cellular level, which then alters gene expression and causes DNA damage. The researchers note that the role of nitrosamines has been well-studied, and their role as a carcinogen has been fully documented. The investigators propose that the cellular alterations that occur as a result of nitrosamine exposure are fundamentally similar to those that occur with aging, as well as Alzheimer’s, Parkinson’s and Type 2 diabetes mellitus.
De la Monte comments, “All of these diseases are associated with increased insulin resistance and DNA damage. Their prevalence rates have all increased radically over the past several decades and show no sign of plateau. Because there has been a relatively short time interval associated with the dramatic shift in disease incidence and prevalence rates, we believe this is due to exposure-related rather than genetic etiologies.”

"Japan fears massive jellyfish invasion this year"
Posted at Pinktentacle:
Japanese researchers monitoring the activity of giant jellyfish in Chinese waters are warning of a potentially historic and catastrophic invasion this year.
Marine surveys conducted in late June have revealed alarming numbers of Nomura’s jellyfish — massive creatures that grow up to 2 meters (6 ft 7 in) in diameter and weigh as much as to 220 kilograms (about 450 lbs) — lurking in the Yellow Sea and East China Sea. The researchers warn that ocean currents may bring swarms of the monster jellies to Japan, which has been plagued by similar invasions in recent years.
Based on what they have seen so far, the researchers warn this year’s onslaught of Nomura’s jellyfish (Nemopilema nomurai, or Echizen kurage in Japanese) could deliver a massive blow to Japan’s fishing industry, rivaling even the devastating 2005 deluge that caused tens of billions of yen (hundreds of millions of dollars) in damage nationwide.
The surveys are being conducted by a team led by Shinichi Ue, a professor of biological oceanography at Hiroshima University who also chairs a government research committee tasked with developing technology to predict and control jellyfish explosions. Ue has been monitoring the population density of Nomura’s jellyfish in the southern Yellow Sea and northern East China Sea since 2006.
Between June 20 and 24, 2009, Ue’s team observed numerous specimens with umbrellas measuring 10 to 50 centimeters across, and they calculated an average distribution of 2.14 jellyfish per 100 square meters. This figure is more than 200 times higher than the 0.01 jellyfish per 100 square meters observed in the same region in 2008. It is also nearly triple the 0.77 jellyfish per 100 square meters observed in 2007, when the fishing industry in the Sea of Japan suffered widespread damage.
To make matters worse, this year’s swarms appear to be taking a more direct and southerly route to Japan, unlike in 2007 when the jellyfish appeared to take a more northerly route, approaching the Sea of Japan coast from the direction of Korea. According to the researchers, the ocean currents could bring unprecedented numbers of Nomura’s jellyfish to Japan’s Pacific coast, which typically sees far fewer of the monster blobs than the Sea of Japan coast.
Nomura’s jellyfish typically bloom in Chinese waters in spring, and they mature into adults as ocean currents slowly carry them north. By July, when the first swarms reach Tsushima (just north of the southern island of Kyushu), many jellyfish are as large as sumo wrestlers. At this size, it only takes about 5 or 10 of them to destroy a commercial fishing net.
In addition to damaging nets, the giant jellyfish are blamed for killing other fish with their venom, lowering the quality and quantity of catches, increasing the risk of capsizing trawlers, and stinging fishermen.
In 2005, the fishing industry reported over 100,000 cases of jellyfish-related damage nationwide. At the peak of the invasion that year, an estimated 300 to 500 million monster jellyfish passed through the Tsushima Strait into the Sea of Japan each day.
