WINDSOR, Ontario — Assumption Park gives residents of this city lovely views of the Ambassador Bridge and the Detroit skyline. Lately they’ve been treated to another sight: a three-story pile of petroleum coke covering an entire city block on the other side of the Detroit River.

Brian Masse, a member of the Canadian Parliament, wants a bilateral agency to investigate the pile accumulating in Detroit.

 

Detroit’s ever-growing black mountain is the unloved, unwanted and long overlooked byproduct of Canada’s oil sands boom.

And no one knows quite what to do about it, except Koch Carbon, which owns it.

The company is controlled by Charles and David Koch, wealthy industrialists who back a number of conservative and libertarian causes including activist groups that challenge the science behind climate change. The company sells the high-sulfur, high-carbon waste, usually overseas, where it is burned as fuel.

The coke comes from a refinery alongside the river owned by Marathon Petroleum, which has been there since 1930. But it began refining exports from the Canadian oil sands — and producing the waste that is sold to Koch — only in November.

“What is really, really disturbing to me is how some companies treat the city of Detroit as a dumping ground,” said Rashida Tlaib, the Michigan state representative for that part of Detroit. “Nobody knew this was going to happen.” Almost 56 percent of Canada’s oil production is from the petroleum-soaked oil sands of northern Alberta, more than 2,000 miles north.

An initial refining process known as coking, which releases the oil from the tarlike bitumen in the oil sands, also leaves the petroleum coke, of which Canada has 79.8 million tons stockpiled. Some is dumped in open-pit oil sands mines and tailing ponds in Alberta. Much is just piled up there.

Detroit’s pile will not be the only one. Canada’s efforts to sell more products derived from oil sands to the United States, which include transporting it through the proposed Keystone XL pipeline, have pulled more coking south to American refineries, creating more waste product here.

Marathon Petroleum’s plant in Detroit processes 28,000 barrels a day of the oil sands bitumen.

Residents on both sides of the Detroit River are concerned that the coke mountain is both an environmental threat and an eyesore.

“Here’s a little bit of Alberta,” said Brian Masse, one of Windsor’s Parliament members. “For those that thought they were immune from the oil sands and the consequences of them, we’re now seeing up front and center that we’re not.”

Mr. Masse wants the International Joint Commission, the bilateral agency that governs the Great Lakes, to investigate the pile. Michigan’s state environmental regulatory agency has submitted a formal request to Detroit Bulk Storage, the company holding the material for Koch Carbon, to change its storage methods. Michigan politicians and environmental groups have also joined cause with Windsor residents. Paul Baltzer, a spokesman for Koch’s parent company, Koch Companies Public Sector, did not respond to questions about its storage or the ultimate destination of the petroleum coke.

Coke, which is mainly carbon, is an essential ingredient in steelmaking as well as producing the electrical anodes used to make aluminum.

While there is high demand from both those industries, the small grains and high sulfur content of this petroleum coke make it largely unusable for those purposes, said Kerry Satterthwaite, a petroleum coke analyst at Roskill Information Services, a commodities analysis company based in London.

“It is worse than a byproduct,” Ms. Satterthwaite said.“It’s a waste byproduct that is costly and inconvenient to store, but effectively costs nothing to produce.”

Murray Gray, the scientific director for the Center for Oil Sands Innovation at the University of Alberta, said that about two years ago, Alberta backed away from plans to use the petroleum coke as a fuel source, partly over concerns about greenhouse-gas emissions. Some of it is burned there, however, to power coking plants.

The Keystone XL pipeline will provide Gulf Coast refineries with a steady supply of diluted bitumen from the oil sands. The plants on the coast, like the coking refineries concentrated in California to deal with that state’s heavy crude oil, are positioned to ship the waste to China or Mexico, where it is burned as a fuel. California exports about 128,000 barrels of petroleum coke a day, mainly to China.

Tony McCallum, a spokesman for the Canadian Association of Petroleum Producers, played down the impact of Keystone XL. “Most of the Canadian oil earmarked for the U.S. Gulf Coast is to replace declining heavy oil imports from Mexico and Venezuela that produces the same amount of petcoke, so it doesn’t create a new issue,” he wrote in an e-mail.

Much of the new coking investment has gone into refineries in the Midwest to allow them to take advantage of the oil sands. BP, the British energy company, is building what it describes as the second-largest coke refinery in Whiting, Ind. When completed, the unit will be able to process about 102,000 barrels of bitumen or other heavy oils a day.

And what about the leftover coke? The Environmental Protection Agency will no longer allow any new licenses permitting the burning of petroleum coke in the United States. But D. Mark Routt, a staff energy consultant at KBC Advanced Technologies in Houston, said that overseas companies saw it as a cheap alternative to low-grade coal. In China, it is used to generate electricity, adding to that country’s air-quality problems. There is also strong demand from India and Latin America for American petroleum coke, where it mainly fuels cement-making kilns.

“I’m not making a value statement, but it comes down to emission controls,” Mr. Routt said. “Other people don’t seem to have a problem, which is why it is going to Mexico, which is why it is going to China.”

“One man’s junk is another man’s treasure,” he said. One of the world’s largest dealers of petroleum coke is the Oxbow Corporation, which sells about 11 million tons of fuel-grade coke a year. It is owned by William I. Koch, a brother of David and Charles.

Lorne Stockman, who recently published a study on petroleum coke for the environmental group Oil Change International, says, “It’s really the dirtiest residue from the dirtiest oil on earth,” he said.

Rhonda Anderson, an organizing representative of the Sierra Club in Detroit, said that the mountain’s rise took her group by surprise, but it had one benefit.

“Those piles kind of hit us upside to the head,” she said. “But it also triggered a kind of relationship between Canada and the United States that’s allowed us to work together.”

Hurricane Isaac Threatens To Swamp Republican Convention – ABC News


 

Hurricane Could Make a Mess of RNC

 

By AMY BINGHAM 

Aug. 22, 2012

 

Hurricane Isaac, currently a tropical storm brewing southeast of Puerto Rico, is on track to hit Florida the same day that Mitt Romney and 50,000 Republican delegates, journalists, protestors and guests descend on Tampa for the Republican National Convention.

While it is too early to accurately predict the storm’s path, ABC meteorologist Max Golembo said it will hit southern Florida. Whether it will skim the east coast near Miami or crash head-on into Tampa, is still up in the air.

“Any way you take it, it’s going to be a wind and rain event in Tampa,” Golembo said. “We don’t know if it’s going to be damaging to Tampa, cancelling the convention or just delaying it.”

As of this morning, the worst possible scenario is that Hurricane Isaac stays on the western track, skating over the Caribbean Sea south of Haiti, crossing the primarily flat landscape of western Cuba into the Gulf of Mexico then curving east and hitting Tampa dead-on.

“Tampa is just as vulnerable as New Orleans was in the sense that the water will funnel into the bay area and from the storm surge which will flood completely the whole entire city of Tampa,” Golembo said referring to Hurricane Katrina that devastated New Orleans in 2005.

“It would be a disaster in the Tampa area,” Golembo said.

But Tampa Mayor Bob Buckhorn downplayed any serious threat to the convention.

“Come on down,” Buckhorn said. “The event is going to take place, it’s going to be a great event and we’re looking forward to having you.”

He said Isaac was still 2,500 miles off the Florida coast and “is not an imminent threat.”

While most prediction models show the storm taking a more eastern track, Golembo said one “very important model,” one the meteorologists use “a lot,” has Isaac slamming directly into Tampa.

“That’s why the meteorologists are pulling their hair out right now,” Golembo said. “If it was a model we wouldn’t care, but it’s THE model.”

Buckhorn said “at this point we don’t lose a lot of sleep over” the possible storm because Floridians are “accustomed to these types of storms.”

“We haven’t been hit by a hurricane in 90 years, but that doesn’t mean we let our guard down,” Buckhorn said. “We’ve got plans in place that we practice all year round. We’ve got plans on top of plans. The only thing the RNC does is add about 50,000 more people to the equation.”

The Republican National Convention has been working with local, state and federal authorities for more than a year to create contingency plans in the event this worst case scenario came true. RNC spokesman James Davis told ABC News that convention planners are “monitoring the storm” and “will make sure everyone’s health and safety is protected.”

“We will release information as we get it. Right now we are looking forward to having a great convention,” Davis said. “We are confident we will be able to get the business done of our convention which is to nominate Mitt Romney and Paul Ryan.”

Davis would not say when or if the convention would be called off, rescheduled or moved.

Under the best case scenario, the storm could smash into the mountains of Haiti which “would really kill the system,” then the weakened storm could sweep over the Bahamas and swirl off the east coast of Florida, bringing strong winds and rain to Miami, but missing Tampa, Golembo said.

In that scenario, Tampa would see 30 mph winds and about 1 inch of rainfall, Golembo said.

The weatherman said, “I don’t think they would have to cancel anything.”

“Pack an umbrella at least and maybe a poncho and galoshes, but don’t quite break out the boats and don’t start building the arc,” Golembo said.

New Study Suggests Pacific Ocean is Polluted With… Coffee? | Inhabitat – Sustainable Design Innovation, Eco Architecture, Green Building


 


New Study Suggests Pacific Ocean is Polluted With… Coffee?

by Josh Gellers, 08/07/12

Coffee, Close-Up, Bubbles

People aren’t the only ones getting a jolt from caffeine these days; in a new study published inMarine Pollution Bulletin, scientists found elevated concentrations of caffeine in the Pacific Ocean in areas off the coast of Oregon. With all those coffee drinkers in the Pacific Northwest, it should be no surprise that human waste containing caffeine would ultimately make its way through municipal water systems and out to sea – but how will the presence of caffeine in our oceans affect human health and natural ecosystems?

 

 

 


Plastic Garbage, Underwater, Great Pacific Garbage Patch

The precise impacts that exposure to caffeinated seas may have on humans are not well known. However, related research indicates that evidence of caffeine contamination serves as a good indicator for the presence of other potentially harmful pollutants that have found their way into our waterways, such as prescription medication and hormones. The effects on aquatic life are also not well understood, but lab studies have already demonstrated that higher levels of caffeine in the water have been shown to produce cellular stress in intertidal mussels.

The study showing abnormal levels of caffeine in the waters off the Oregon coast also suggested that the contaminants were predominantly coming from small-scale waste treatment systems such as household septic tanks, as opposed to large-scale wastewater treatment plants, which are regulated with much greater scrutiny. Such massive facilities are well-equipped to process the waste originating from cities in Oregon, which are comparatively smaller than major metropolitan hubs that have much more waste to contend with. For example, in Massachusetts, high levels of caffeine have been detected in Boston Harbor, likely the result of significantly greater quantities of wastewater that require treatment than those present in Oregon.

With so much uncertainty surrounding the effects of caffeine pollution on an ocean already marred by the presence of plastic garbage islands, how much research needs to be conducted before cities decide to embark upon ambitious ocean-cleansing efforts? Hopefully, leaders won’t need to convene over coffee to figure out the right course of action.

Why Shell is betting billions to drill for oil in Alaska – Fortune Features


Why Shell is betting billions to drill for oil in Alaska

May 24, 2012: 9:19 AM ET

This summer, the energy giant will begin exploring off the icy coast of Alaska — after years of resistance by environmentalists. The payoff could be the largest U.S. offshore oil discovery in a generation.

By Jon Birger, contributor

In Barrow, Alaska, the northernmost city in the U.S., it's hard to tell where the land ends and the frozen Arctic Ocean begins. The average temperature stays below freezing for eight months of the year.

In Barrow, Alaska, the northernmost city in the U.S., it’s hard to tell where the land ends and the frozen Arctic Ocean begins. The average temperature stays below freezing for eight months of the year.

 

FORTUNE — Pete Slaiby is eating breakfast with an Eskimo businessman at a Mexican restaurant across the street from the Arctic Ocean when two Coast Guard admirals happen to walk in. It’s 8 a.m. on a Tuesday in late March. Outside the temperature is an extremity-tingling, -35° F. Look 100 yards north, and it’s not at all clear where the snow-covered land ends and the ice-covered ocean begins. Slaiby, Royal Dutch Shell’s vice president for Alaska, rises to give the Coast Guard brass a warm welcome before they grab a nearby table. “Welcome to Barrow,” he says wryly as he sits back down to his plate of huevos and reindeer sausage.

Indeed, it’s a typical morning at Pepe’s, a hole-in-the-wall eatery in Barrow, Alaska, population 4,300, the northernmost municipality in the United States. Everyone is there for the same reason. And with apologies to Pepe’s colorful longtime proprietor Fran Tate — whose claim to fame is presenting Johnny Carson with an oosik, a walrus penis bone, during a 1984 appearance on The Tonight Show — it’s not the cuisine. They’ve all come to Barrow because some 100 miles offshore, in the Arctic Ocean’s Chukchi and Beaufort seas, lies what U.S. government geologists believe is 27 billion barrels of recoverable oil. Slaiby wants Shell (RDSA) to be the first company to get that oil out of the seabed. The Eskimo is a subcontractor who wants a piece of Shell’s business. And the admirals want to ensure that a drilling accident doesn’t happen in an ocean ecosystem that environmentalists consider to be one of the most unspoiled on the planet.

Alaska’s outer-continental shelf has been off limits to oil companies — despite the fact that Shell paid the U.S. government $2.2 billion for drilling rights back in 2005 and 2008. But that’s about to change. After years of lawsuits, regulatory hitches, and other delays, Shell will finally sink its first exploratory wells in July, making this the first new offshore drilling project approved by the government since the 2010 BP (BP) disaster in the Gulf of Mexico. Come fall, the big news out of Barrow may well be America’s largest offshore oil discovery in a generation. “We can’t know,” says Slaiby, “until we start drilling.”

The stakes are huge — for Shell, for the environment, for the oil industry, and for the oil-addicted U.S. economy. The fact is, oil demand is soaring. Worldwide oil consumption is now running at 89 million barrels a day, according to the International Energy Agency. Not only is that up 6% from the lows of the recession — a big increase given tight supplies — but it’s also above the pre-recession peak of 87 million barrels notched in 2008.

 

 

In the U.S. the clearest consequence of surging oil demand has been a sharp increase in the average price of gasoline — from a recession low of $1.87 a gallon in December 2008 to a recent price of $3.75. Unsurprisingly, high gas prices have emerged as a red-hot political issue. President Barack Obama’s supporters argue that domestic oil production is at an eight-year high. Republicans, who want to open upmore public land to drilling, counter that most of the production growth has occurred on privately held lands — which means Alaska could become a powerful counterpoint to Republican attacks. “Everybody is being squeezed at the pump,” says Whit Sheard, a senior lawyer for Oceana, one of the environmental groups opposing Shell’s Alaskan plans, “and there’s a perception — a wrong one in my view — that drilling there will reduce prices.”

Looming over the debate are still-fresh memories of the explosion of BP’s Deepwater Horizon drilling rig in 2010. The death of 11 crewmen and the subsequent spilling of 5 million barrels of crude oil into the Gulf of Mexico have raised tough questions about domestic drilling. Can the safety assurances of oil companies be trusted? What risks are we and aren’t we prepared to take in order to quench our thirst for oil? Oil companies are attempting to restore offshore drilling’s reputation while simultaneously seeking access to environmentally sensitive Arctic regions — believed by scientists to hold some 22% of the world’s undiscovered oil and gas. Tyler Priest, senior policy analyst to the President’s National Commission on the BP Deepwater Horizon Oil Spill and Offshore Drilling, says he was surprised how quickly the debate over the BP spill morphed into a referendum on Alaska. “The environmentalists clearly wanted to use Deepwater Horizon as a justification to prevent offshore drilling in Alaska,” says Priest, an oil industry historian and professor at the University of Houston’s Bauer College of Business. “The oil companies wanted to prove that they could drill up there safely.”

That’s why Shell’s performance in Alaska — not only how much oil it finds but also whether drilling can be done with a minimal environmental footprint — will be so closely watched. “The eyes of the world are going to be on the Arctic this summer,” says U.S. Sen. Mark Begich of Alaska, a pro-drilling Democrat who has been one of Shell’s key allies.

Shell finally has all the major permits, which means its drilling ships, specially designed for use in the icy waters of the Arctic, will soon make their way north toward Barrow from their temporary home in Seattle. Even with icebreakers on duty, it’s only possible to operate in Arctic waters during the summer thaw. Before sinking a single well, Shell will have already invested $4.5 billion in its Alaska project — $2.3 billion assembling the necessary equipment and personnel on top of the $2.2 billion for the leases. The wells Shell will begin drilling in July are exploratory, not producing. So assuming Shell does find oil, it would be another seven to 10 years before it’s able to drill producing wells, install permanent platforms, and build the offshore and onshore pipelines required to get Arctic oil to consumers in the lower 48. By then, the up-front investment for Shell, which reported $31 billion in profits for 2011, will probably have topped $7 billion.

Typically, only one out of every two or three exploratory wells drilled strikes oil or natural gas. Such modest success rates make Shell’s Arctic bet appear risky. However, Shell knows there is oil offshore in Alaska because it owned leases and drilled wells in the Chukchi and Beaufort seas in the 1980s and 1990s. It abandoned them only because the $20-a-barrel prices at the time did not justify the expense of further drilling. “They would not have committed so many resources if they didn’t believe this was a sure thing,” says Eric van Oort, a former Shell engineer who is now a professor of petroleum engineering at the University of Texas.

One of Shell’s strategies in recent years has been to deploy capital in politically stable regions where obstacles to oil and gas development are less daunting than in, say, Nigeria. Shell’s Nigerian operations have been hindered by the hijacking of its oil rigs and the all-too-frequent kidnapping of its employees. In Alaska nobody is going to be brandishing guns at Shell workers. Nevertheless, the U.S. permitting process has proved more vexing than anyone at Shell headquarters in The Hague ever anticipated.

It took two years to get the proper permits, and just as Shell seemed on the verge of beginning drilling in 2010, Deepwater Horizon happened and the U.S. Department of Interior issued its moratorium. A year later, Shell’s plans for drilling in 2011 had to be canceled after the Environmental Protection Agency issued an 11th-hour ruling requiring Shell to install $60 million exhaust-filtration systems on its ships — systems Slaiby believed were unnecessary. “It’s ridiculous,” Slaiby says, in a rare flash of frustration. “But I guess it doesn’t matter how good your air is if they don’t like the product that you’re selling.”

Imagine the prototype front man for an oil company — hard-driving, charming, on-message — and he would look a lot like the 53-yearold Slaiby. Ask the Shell lifer, who grew up outside Hartford, Conn., and studied mechanical engineering at Vanderbilt, whether he’s irritated by the grinding regulatory process, post-BP spill, and he treads carefully: “We’ve never been out there asking for lower standards, only a more streamlined process.” What about the environmental groups that have fought Shell at every step? “For environmentalists there’s a lot of emotional energy tied up in Alaska,” he says. As for the Eskimo population, “Shell is going to be here for the next 50 to 75 years, so it’s important to us the people here believe in what we’re doing.”

Ever since Slaiby arrived in Alaska in 2008 — he took the assignment reluctantly, he says, after much warmer gigs in Brunei and Brazil — his focus has been on winning hearts and minds of the Alaskan North Slopers who hunt and fish for food and who fear a Deepwater Horizon in their backyard. Slaiby has made more than 40 trips to Barrow and attended dozens of community meetings. “Pete has been relentless,” says Begich. Even those wary of Shell’s plans appreciate Slaiby’s efforts to find common ground. “I’m a long ways from putting up a driftwood fire by the beach with him and singing ‘Kumbaya,’ ” says Edward Itta, mayor of the North Slope Borough from 2005 to 2011. “But personally I do like Pete Slaiby.”

From Shell’s perspective, and that of Alaska’s Republican governor, Sean Parnell, the problem with the U.S. regulatory process is that there is no clear finish line. “It’s far too open-ended,” says Slaiby. New legal challenges can seemingly always be filed, and different regulators sometimes make conflicting demands. “The federal government has demonstrated that their permitting process is broken,” adds Parnell. Trying to head off yet another last-minute postponement, Shell went so far this year as to file a preemptive lawsuit against environmental groups that might file a legal challenge to the Shell oil-spill response plan approved by the Department of the Interior in February.

Shell took this unusual legal step to get the court to review the plan now to avoid challenges on the eve of summer drilling. In fact, on May 16, a coalition of environmental and native Alaskan groups did file a different last-minute challenge — to Shell’s EPA air permit — alleging that Shell’s ships “will pump tens of thousands of tons of pollution into pristine Arctic skies.”

The prize that Shell is chasing is worth the ongoing frustration: the estimated 27 billion barrels of recoverable oil held in Alaska’s outer-continental shelf — plus another 130 trillion cubic feet of natural gas. At its peak, offshore oil production in the region could top 1.45 million barrels a day. “Shell is making big bet there, but I think it’s justified based on the geology,” says Oswald Clint, an oil analyst at Sanford C. Bernstein and a geophysicist by training.

Shell says that it expects the 410 Alaskan offshore leases it holds in the Arctic to become the company’s biggest source of crude oil globally within 10 to 20 years. Were it to capture just a 10th of the oil in the Chukchi and Beaufort seas, Shell would, over time, add 2.7 billion barrels to its proven reserves. To put that number into perspective, Shell’s total proven reserves of oil stood at 4.3 billion barrels at the end of 2011. Given Shell’s perpetual need to find new reserves large enough to replace what it pumps, the company must aim high when it comes to exploration, says Clint, the Bernstein analyst. “Adding 200 million barrels in new reserves doesn’t move the needle for an oil company as big as Shell,” Clint says. “They really have no choice but to push into the big, unexplored basins like the Arctic.”

It’s not entirely clear how those new reserves will affect Shell’s profitability, since Shell won’t discuss its production costs in the Arctic. Some analysts estimate the price of offshore Arctic production at $70 to $80 a barrel. However, one scientist who has been involved in the Shell project says he expects the cost to be closer to $30. A November 2011 report by the U.S. Bureau of Ocean Energy Management appears to support the lower, $30-a-barrel assessment. The BOEM estimates the oil “hurdle price” necessary to justify the cost of Arctic drilling at $38 a barrel for Chukchi oil and $29 a barrel for the Beaufort.

Factor in yet-to-be-determined royalty rates, and it’s reasonable to peg Shell’s profit margin on Alaskan crude just a notch or two below the 39% margin Shell reported on total U.S. production back in 2008 — the last time prices were consistently above $100 a barrel. Bottom line: Each 100,000 barrels a day in new production could net Shell $1 billion or more in annual profits depending upon prevailing oil prices. “Let’s just say it’s large enough to have a significant impact,” says Marvin Odum, president of Shell’s U.S. subsidiary.

 

The math gets a lot more challenging if oil prices fall significantly. Even if they don’t fall, the three-month-a-year drilling window means it will take longer for Shell to earn back its investment. “To me, it looks like a bad decision by an otherwise well-run company,” says an energy analyst at one of Shell’s major mutual fund shareholders.

From an engineering perspective, Slaiby argues that Alaska is a less challenging endeavor thandrilling in the Gulf of Mexico. The Alaskan waters where Shell will be drilling generally have depths of 150 feet, vs. the 5,000-foot depths where BP was drilling in the Gulf. “We’ll be drilling in much shallower water with lower gas pressures,” he says.

Intense gas pressures were a contributing factor to Deepwater Horizon. It was the failure of the blowout protector — a $20 million piece of equipment that rests on the ocean floor and prevents natural gas from rushing uncontrollably up the rig and blowing pipes out of the bore hole — that caused the explosion. The blowout protectors Shell will use have an extra cutoff valve just in case the main one fails. In another nod to Deepwater Horizon, Shell will have on standby the same type of capping and containment systems that ultimately stopped the BP blowout. Shell says the equipment can be deployed within hours, even in icy conditions, and will be stored on icebreaker support ships positioned between the Chukchi and Beaufort drilling locations. Of course, conditions in the Arctic are much different from those in the Gulf.

While the water may be much deeper in the Gulf, drillers there don’t have to deal with crushing ice floes, Arctic hurricanes, and total darkness for 70 days a year. “Any oil that’s spilled under ice is almost impossible to deal with,” says Sheard, the Oceana lawyer. “We’re setting ourselves up for a disaster.” Environmentalists are especially concerned that the areas where Shell intends to drill overlap with vital migration routes for whales, walruses, and other marine life. “Depending upon the time of year, an accident could wipe out an entire species, specifically bowhead whales,” says Layla Hughes, senior program officer in Alaska for the World Wildlife Fund.

Even ecologists who have worked with the oil industry in the Gulf have doubts. “Drilling in the Arctic is far riskier than in the Gulf,” says Larry McKinney, executive director at the Harte Research Institute for Gulf of Mexico Studies at Texas A&M in Corpus Christi. “I’m sure they’re going to be cautious, but it would be a technological miracle if something bad doesn’t happen. If there’s a blowout, it could be five months before they’re able to drill a relief well, depending upon the ice and the time of year.”

Slaiby disputes such a scenario, noting that drilling will be suspended by late summer, which means there will be a one- or two-month window for Shell to deal with a spill or blowout before the ocean starts to freeze. He also says Shell is prepared to work under the ice if necessary. Slaiby can’t guarantee an accident-free operation though — no oil company can — and this reality creates a torturous dilemma for the Inupiat Eskimos who live in Barrow and the other communities in Alaska’s North Slope. Nobody exemplifies this dilemma more than Itta, the 66-year-old former mayor of the North Slope Borough.

 

The Inupiat Eskimos worry that offshore drilling in water they consider sacred could endanger the whale hunting that is central to their culture.

The Inupiat Eskimos worry that offshore drilling in water they consider sacred could endanger the whale hunting that is central to their culture.

 

The Inupiat culture, not to mention its diet, revolves around the hunting of walruses, seals, and especially bowhead whales, which is why community leaders in Barrow are so wary of Shell’s plans to drill in waters they consider sacred. On the other hand, the Inupiats’ standard of living has improved dramatically since the inflow of hundreds of millions of tax dollars from the original Alaskan oil boom in nearby Prudhoe Bay, also part of the North Slope Borough.

Prior to 1970, Barrow was literally off the grid, with no electricity system, no water and sewer service, and no high school for local teens. Oil money has transformed life in the city, paying not only for electricity, running water, and a modern high school (with an Olympic-size pool, no less), but also a new airport, hospital, library, community center, roller-skating rink, and community college.

When Itta was first elected mayor, he says his attitude toward offshore drilling was, “Hell no!” and “Over my dead body!” Given the sway of Inupiat and other tribes in Alaskan politics, overwhelming native opposition probably could have killed Shell’s offshore plans. But then the realities of governing sank in. Over 95% of the borough’s tax revenue derives from oil and gas, and production from Prudhoe Bay and other North Slope oilfields has been in steady decline for years — down from 2 million barrels a day in 1988 to 560,000 barrels last year. Not only has that cut into local tax revenue, but continued declines could threaten the viability of the entire North Slope oil industry long before the oil actually runs out.

Alaskan crude oil is transported south via the Trans-Alaska Pipeline, and a 2011 report by the pipeline’s operator, Alyeska Pipeline Service Co., raised doubts about whether the pipeline can operate safely if throughputs continue to decline. The slower the oil moves through the pipeline, the greater the risk that water will separate from the crude and freeze at the bottom of the pipeline during winter, causing corrosion and cracks. This and other risks, according to the Alyeska report, “decrease confidence that the pipeline can be reliably operated at throughputs lower than 350,000 barrels per day.”

“It’s not looking good,” Itta says of the production declines. “And if there’s no oil going through the pipeline, that oil infrastructure becomes worthless, and our tax base goes down.” All of Barrow’s infrastructure was built by oil money, and all of it is now maintained by oil money. “I started realizing,” Itta continues, “that my biggest responsibility was maintaining the economic well-being of the borough, and that largely has to do with maintaining oil in the pipeline.” The low-flow threat to the pipeline is a huge state issue as well, given that over 90% of Alaska’s state revenuescome from oil and gas.

If Itta had his way, the new oil for the pipeline would come not from offshore drilling but from the Arctic National Wildlife Refuge — better known as ANWR (“An-war”) and believed to hold about 10 billion barrels of recoverable oil. “You can clean up oil so much easier onshore, and the risks are not even comparable,” says Itta. “It’s been befuddling that we have all this potential oil and gas onshore, and yet that seems to be sacred to environmental groups. But it’s the reality we deal with.”

Itta gradually came to accept Shell’s plans — a grudging acceptance but one Slaiby views as crucial. Still, even after wringing several key concessions from Shell — the most important being a promise to cease drilling during whale hunts — Itta still wonders whether his decision to throw his support behind Shell was the right one. He doesn’t trust Shell’s ability to clean up a significant oil spill, especially if oil is trapped beneath ice.

A whaling boat captain himself, Itta emphasizes that Inupiat concerns about the whale hunt are as much about culture as food: “We have a culture that has survived one of the harshest environments on earth for thousands of years, and that culture is really what’s at stake.” The values of the whale hunt are the values of his people, Itta continues. “No one person can catch a whale. It takes a whole community. Because of the whale, we share, we are very close, we come together. Without it, our way of life — what we pass on to our kids and grandkids — would be diminished. The whale is what binds us. So this is my personal battle. Am I going to be the one remembered for my children’s children being able to enjoy the same standard of living I have now? Or will I be remembered as the one who helped destroy our way of life?”

It’s a heavy burden for any man. When pressed on whether he truly wants Shell to find a lot of oil this summer, Itta pauses before answering. “I hope they don’t. Maybe then we can have meaningful discussions about drilling in ANWR.” For Slaiby and Shell, however, the time for talking is finally over. They’re ready to drill.

Amsterdam Tries to Change Culture With ‘Repair Cafes’ – NYTimes.com


An Effort to Bury a Throwaway Culture One Repair at a Time

Ilvy Njiokiktjien for The New York Times

Gathered around tables in what appeared to be delicate operations, participants tried to fix items that had been set for the trash.

 

By SALLY McGRANE
Published: May 8, 2012

 

AMSTERDAM — An unemployed man, a retired pharmacist and an upholsterer took their stations, behind tables covered in red gingham. Screwdrivers and sewing machines stood at the ready. Coffee, tea and cookies circulated. Hilij Held, a neighbor, wheeled in a zebra-striped suitcase and extracted a well-used iron. “It doesn’t work anymore,” she said. “No steam.”

 

Ms. Held had come to the right place. At Amsterdam’s first Repair Cafe, an event originally held in a theater’s foyer, then in a rented room in a former hotel and now in a community center a couple of times a month, people can bring in whatever they want to have repaired, at no cost, by volunteers who just like to fix things.

Conceived of as a way to help people reduce waste, the Repair Cafe concept has taken off since its debut two and a half years ago. The Repair Cafe Foundation has raised about $525,000 through a grant from the Dutch government, support from foundations and small donations, all of which pay for staffing, marketing and even a Repair Cafe bus.

Thirty groups have started Repair Cafes across the Netherlands, where neighbors pool their skills and labor for a few hours a month to mend holey clothing and revivify old coffee makers, broken lamps, vacuum cleaners and toasters, as well as at least one electric organ, a washing machine and an orange juice press.

“In Europe, we throw out so many things,” said Martine Postma, a former journalist who came up with the concept after the birth of her second child led her to think more about the environment. “It’s a shame, because the things we throw away are usually not that broken. There are more and more people in the world, and we can’t keep handling things the way we do.

“I had the feeling I wanted to do something, not just write about it,” she said. But she was troubled by the question: “How do you try to do this as a normal person in your daily life?”

Inspired by a design exhibit about the creative, cultural and economic benefits of repairing and recycling, she decided that helping people fix things was a practical way to prevent unnecessary waste.

“Sustainability discussions are often about ideals, about what could be,” Ms. Postma said. “After a certain number of workshops on how to grow your own mushrooms, people get tired. This is very hands on, very concrete. It’s about doing something together, in the here and now.”

While the Netherlands puts less than 3 percent of its municipal waste into landfills, there is still room for improvement, according to Joop Atsma, the state secretary for infrastructure and the environment.

“The Repair Cafe is an effective way to raise awareness that discarded objects are indeed still of value,” Mr. Atsma wrote in an e-mail.

“I think it’s a great idea,” said Han van Kasteren, a professor at the Eindhoven University of Technology who works on waste issues. “The social effect alone is important. When you get people together to do something for the environment, you raise consciousness. And repairing a vacuum cleaner is a good feeling.”

That was certainly true for the woman who brought her 40-year-old vacuum, bought when she was a newlywed, to a Tuesday night Repair Cafe. “I am very glad, very glad,” she said as John Zuidema, 70, sawed off the vacuum’s broken nozzle. “My husband died, and there are all these little things around the house that he used to fix.”

To some, the project’s social benefits are as appealing as its ecological mission. “What’s interesting for us is that it creates new places for people to meet, not just live next to each other like strangers,” said Nina Tellegen, the director of the DOEN Foundation, which provided the Repair Cafe with a grant of more than $260,000 as part of its “social cohesion” program, initiated in the wake of the political murders of Pim Fortuyn, a politician, in 2002, and Theo van Gogh, a filmmaker, in 2004. “That it’s linked to sustainability makes it even more interesting.”

Ms. Tellegen added that older people in particular find a niche at the Repair Cafe.

“They have skills that have been lost,” she said. “We used to have a lot of people who worked with their hands, but our whole society has developed into something service-based.”

Evelien H. Tonkens, a sociology professor at the University of Amsterdam, agreed. “It’s very much a sign of the times,” said Dr. Tonkens, who noted that the Repair Cafe’s anti-consumerist, anti-market, do-it-ourselves ethos is part of a more general movement in the Netherlands to improve everyday conditions through grass-roots social activism.

“It’s definitely not a business model,” Ms. Postma said. She added that because the Repair Cafe caters to people who find it too expensive to have their items fixed, it should not compete with existing repair shops.

The Repair Cafe Foundation provides interested groups with information to help get them started, including lists of tools, tips for raising money and marketing materials. Ms. Postma has received inquiries from France, Belgium, Germany, Poland, Ukraine, South Africa and Australia.

Tijn Noordenbos, a 62-year-old artist in Delft, started a Repair Cafe there four months ago.

“I like to repair things,” he said, noting that the repair shops of his younger days had all but vanished. “Now, if something breaks, you take it back to the store and they say: ‘We’ll send it to the factory and it costs you 100 euros just to check out the problem. It’s better if you buy a new one.’ ”

William McDonough, an architect, said, “What happened with planned obsolescence is that it became mindless — just throw it away and don’t think about it.” His “cradle to cradle” design philosophy, which posits that things should be built so that they can be taken apart and the raw materials reused (though not necessarily repaired ad nauseam), also inspired Ms. Postma.

“The value of the Repair Cafe is that people are going back into a relationship with the material things around them,” Mr. McDonough said.

Take, for example, Sigrid Deters’s black H&M miniskirt with a hole in it.

“This cost 5 or 10 euros,” about $6.50 to $13, she said, adding that she had not mended it herself because she was too clumsy. “It’s a piece of nothing, you could throw it out and buy a new one. But if it were repaired, I would wear it.”

Marjanne van der Rhee, a Repair Cafe volunteer who hands out data collection forms and keeps the volunteers fortified with coffee, said: “Different people come in. With some, you think, maybe they come because they’re poor. Others look well-off, but they are aware of environmental concerns. Some seem a little bit crazy.”

Theo van den Akker, an accountant by day, had taken on the case of the nonsteaming iron. Wearing a T-shirt that read “Mr. Repair Café,” Mr. van den Akker removed the plastic casing, exposing a nest of multicolored wires.

As he did, Ms. Held and Ms. van der Rhee discussed the traditional Surinamese head scarves that Ms. Held, who was born in Suriname, makes for a living.

When Mr. van den Akker put the iron back together, two parts were left over — no matter, he said, they were probably not that important. He plugged the frayed cord into a socket. A green light went on. Rusty water poured out. Finally, it began to steam.

Wind farms can cause climate change, finds new study – Telegraph


Wind farms can cause climate change, finds new study

 

Wind farms can cause climate change, according to new research, that shows for the first time the new technology is already pushing up temperatures.

29 Apr 2012 

Usually at night the air closer to the ground becomes colder when the sun goes down and the earth cools.

But on huge wind farms the motion of the turbines mixes the air higher in the atmosphere that is warmer, pushing up the overall temperature.

Satellite data over a large area in Texas, that is now covered by four of the world’s largest wind farms, found that over a decade the local temperature went up by almost 1C as more turbines are built.

This could have long term effects on wildlife living in the immediate areas of larger wind farms.

It could also affect regional weather patterns as warmer areas affect the formation of cloud and even wind speeds.

It is reported China is now erecting 36 wind turbines every day and Texas is the largest producer of wind power in the US.

Liming Zhou, Research Associate Professor at the Department of Atmospheric and Environmental Sciences at the University of New York, who led the study, said further research is needed into the affect of the new technology on the wider environment.

“Wind energy is among the world’s fastest growing sources of energy. The US wind industry has experienced a remarkably rapid expansion of capacity in recent years,” he said. “While converting wind’s kinetic energy into electricity, wind turbines modify surface-atmosphere exchanges and transfer of energy, momentum, mass and moisture within the atmosphere. These changes, if spatially large enough, might have noticeable impacts on local to regional weather and climate.”

The study, published in Nature, found a “significant warming trend” of up to 0.72C (1.37F) per decade, particularly at night-time, over wind farms relative to near-by non-wind-farm regions.

The team studied satellite data showing land surface temperature in west-central Texas.

“The spatial pattern of the warming resembles the geographic distribution of wind turbines and the year-to-year land surface temperature over wind farms shows a persistent upward trend from 2003 to 2011, consistent with the increasing number of operational wind turbines with time,” said Prof Zhou.

However Prof Zhou pointed out the most extreme changes were just at night and the overall changes may be smaller.

Also, it is much smaller than the estimated change caused by other factors such as man made global warming.

“Overall, the warming effect reported in this study is local and is small compared to the strong background year-to-year land surface temperature changes,” he added.

The study read: “Despite debates regarding the possible impacts of wind farms on regional to global scale weather and climate, modelling studies agree that they can significantly affect local scale meteorology.”

Professor Steven Sherwood, co-Director of the Climate Change Research Centre at the University of New South Wales, said the research was ‘pretty solid’.

“This makes sense, since at night the ground becomes much cooler than the air just a few hundred meters above the surface, and the wind farms generate gentle turbulence near the ground that causes these to mix together, thus the ground doesn’t get quite as cool. This same strategy is commonly used by fruit growers (who fly helicopters over the orchards rather than windmills) to combat early morning frosts.”

Obama’s Solar Policy: If You Can’t Beat the Chinese, Tax Them – Forbes


Obama’s Solar Policy: If You Can’t Beat the Chinese, Tax Them

By Alex B. Berezow and Hank Campbell

 

Why is it right for Americans to provide low-cost loans to its solar panel manufacturers, but when China does it, it is an illegal subsidy and demands tariffs in response?

The answer to that also addresses a fundamental science policy question: Why do Americans insist on subsidizing solar panels no one wants to buy?

Solar power will hopefully be the energy of the future. Enough sunlight reaches Earth in a single hour to power the planet for an entire year. However, significant hurdles, such as efficiency, storage and transmission, have held it back for the last 50 years. Breakthroughs are just around the corner, it has been said for decades, so many venture capitalists stopped buying that dream long ago. But with more scientific research, substantial technological breakthroughs will occur in the not-too-distant future.

No, really. They will.

That’s why, on the surface, President Obama’s support for solar power was sensible, but a closer examination of its implementation reveals contradictory and self-defeating policies.

Solar power is booming. Imports from China were a tepid $21 million in 2005 when Congress and President Bush authorized the solar investment tax credit. It was renewed in 2008, and in 2011 installations totaled nearly $2.7 billion. That’s a huge win for solar. And just as advocates for solar power had hoped, a larger market drove down prices. Solar energy cost has declined by two-thirds in the last four years, meaning it will soon start to close in on fossil fuels.

The only problem is that the American market growth is fake, funded primarily by the government, while the real revenue benefit has occurred for Chinese manufacturers. America, the home of Silicon Valley, basically abandoned thin-film silicon to chase after new technology while China embraced it, once again showing that the U.S. government is not particularly qualified to predict market outcomes or to pick winners and losers in the green tech sector.

To address the widening trade gap, the Obama administration’s Commerce Department accused China of illegally subsidizing solar power manufacturers. They hit them with a 2.9% to 4.73% tariff,  with an even larger one likely to follow in May. The rich irony here is that the administration claims the tariffs are necessary because China has been unfairly lowering the price of solar panels using subsidies in the form of low-interest loans – in other words, exactly the same thing the Obama administration did with Solyndra and a dozen other companies.

China has a nearly inexhaustible cheap labor supply, few environmental standards, and can leverage the power of the state to crank out cheap solar panels. The only real crime here is that China picked the right technology while all the wonks in Obama’s Energy Department consistently picked the wrong ones. Kudos to the technocrats in Beijing.

The administration would respond by saying China is “dumping” solar panels – that is, buying market share with subsidies to drive competitors out of business. With Solyndra, however, Obama did the same thing; he just didn’t violate international trade laws because the goods were not for export. In other words, we were subsidizing things no one wanted to buy.

Additionally, the new tariff may inadvertently punish the American solar industry, as well. Between 40% and 50% of planned solar installations use panels manufactured in China – nearly half the market. So, the Obama administration is making it more expensive for Americans to switch to green energy, an enormous contradiction in the President’s clean energy agenda.

How America got inferior technology at inflated prices at a time when everyone claims they want cleaner power is the real testament to the mismanagement of our energy policy.

There are basically two types of solar panels: Thin-film silicon and everything else. Thin-film solar panels are relatively cheap, while everything else is relatively expensive. Thin-film silicon panels are, however, not all that efficient compared to alternatives or even higher-grade silicon. Copper indium gallium selenide (CIGS) is one example of a more efficient technology (because it has a higher sunlight absorption coefficient than other semiconductors and works better during cloudy days). With research, better manufacturing could make the process more cost-effective, even making CIGS panels superior to silicon. It was exactly this thinking that formed Solyndra’s entire business model. You could say they bet the (solar) farm on it.

But when installations for American solar power became heavily subsidized, sales increased and China ramped up production to meet demand. As the market was flooded by both silicon (from silicon producers) and thin-film panels (by Chinese manufacturers), the price for thin-film panels came crashing down – along with Solyndra’s business model. Instead of supporting basic research to make our energy future better, the Obama administration had attempted to buy market share with an unproven technology – and lost. Big time.

Yet that isn’t the only instance of mismanagement. The whole clean energy program remains flawed, even at the consumer level. The people who are the most likely to be impacted by high energy prices, the poor, are the least likely to benefit from the solar rebate scheme because they lack the capital to pay for the installation. When a house in Napa Valley put in a $1.45 million solar installation, every taxpayer in California, rich and poor, refunded the homeowner $319,000 of the cost — and then they got a federal tax break too. Essentially, rebate programs subsidize the wealthy, who get to decorate their houses with solar panels at everyone else’s expense.

Rather than accept reality – that we got outplayed by China — White House senior adviser David Plouffe blamed the Bush administration. For what? For creating the loan guarantee program that benefited Solyndra in the first place.

So now, the Obama administration is trying to save face by slapping the Chinese with a tariff. If you can’t beat ‘em, tax ‘em. Hawley and Smoot would be pleased.

Hoover Dams for Lilliput: Does Small Hydroelectric Power Have a Future? | Txchnologist

Hoover Dams for Lilliput: Does Small Hydroelectric Power Have a Future?

 

MARCH 27TH, 2012

Kansas is not a state that’s known for its water resources. In fact, when European settlers first reached this region, it was a semi-arid, treeless plain of grass. In 1931, when historian Walter Prescott Webb wrote about the settlement of Kansas, and other Great Plains states, he described “the search for water” as a “continuous and persistent” issue.

It’s not terribly surprising then to learn that Kansas has only a trifling supply of hydroelectric power. Throughout the whole state, there’s just 1 megawatt of hydroelectric capacity – enough to power fewer than 800 homes, or roughly 0.01 percent of the Hoover Dam’s nameplate capacity.

But Kansas has the potential for much more. In fact, the state could be getting almost 300 megawatts of electric capacity from water power – enough electricity for 240,000 homes. The key: That potential is only accessible if you’re willing to think local.

Across the United States, changes are afoot that are making smaller-scale energy generation make appealing. One of the major benefits of this localized power is that it enables us to take advantage of renewable resources that were previously out of reach. This is particularly true for hydroelectric power. In fact, without smaller scale generation, hydro doesn’t have much of a future at all.

A dramatic shift

The United States really can’t build many more large-scale hydroelectric dam and reservoir systems. According to the U.S. Geological Survey, there weren’t enough good reservoir locations to supply all of the energy the United States consumes. What’s more, the best spots are already being used.

In 2006, though, the Department of Energy (DOE) released a paper that took a second look at the potential for hydro power in the United States. It paid serious attention to places where you could make electricity without building a dam.

These sites identified by the DOE would all have capacities of less than 30 megawatts, with some less than 1 megawatt–in contrast to large hydroelectric dams, which usually have capacities of hundreds and thousands of megawatts. What these new sites lack in size, however, they make up for in numbers. The study found 5,400 sites in forty-nine states where dam-less hydroelectric power could be developed in a practical way. Taken together, the sites represent as much as 18,000 additional megawatts of electric capacity we could be using but currently are not. It’s enough to increase the total U.S. hydroelectric capacity by 50 percent —something that wouldn’t be possible to do if we focused only on developing more large hydroelectric dams.

This would require a dramatic shift in the way we think about energy. In fact, for the better part of the 20th century, it made much more economic sense to build large power plants, facilities that can serve millions of homes. But that is starting to change.

Limits to centralized plants

Electricity is a commodity and we make it in bulk. More than 95 percent of our electric generation (pdf) comes from what are called “centralized” power plants (pdf). These are large facilities–most have hundreds of megawatts of capacity each–and they’re located far away from the people who actually use the electricity they produce. Centralized power plants include those that feed on coal and natural gas, but we make renewable energy this way, as well. In 2009, according to the U.S. Energy Information Agency, 7 percent of our electricity came from hydroelectric power and almost 90 percent of that came centralized hydroelectric power plants (pdf).

Centralized generation is cheaper because it creates economies of scale – you need fewer facilities to serve the same number of customers. But there is a catch. When you centralized electric generation, you have to build a lot of transmission lines to move the electricity to customers.

“That means you have to deal with more people,” says Neal Elliott, associate director for research at the American Council for an Energy Efficient Economy. “You can buy your neighbors out to build a power plant, but it’s harder for the transmission lines. You’re talking about thousands of landholders, any of whom can sue you. In many cases, you’re talking about crossing federally protected lands.”

All of that adds cost. Today, say experts like Elliott, it can actually be more expensive to build the transmission lines that feed a centralized power plant, than it is to build the power plant itself. This economic case opens the door for smaller-scale generation that can serve thousands, or hundreds of thousands, rather than millions.

East River hydro

Economic opportunities for smaller-scale electric generation mean opportunities to build more hydroelectric power plants. These dam-less hydroelectric power plants can take many forms, but generally they involve finding ways to use the natural movement of water in a river to electricity generating advantage.

Some of these systems are modern takes on very old-fashioned ideas. The first hydroelectric power plant in the world worked by putting a wheel into the free-flowing Fox River in northern Wisconsin. The river turned the wheel, and that motion operated the electric generator. Some run-of-river hydroelectric systems operating today work in much the same way. Often, these projects involve digging a channel, which diverts part of the river through a hydroelectric power plant. Water runs through, spinning the generator turbines, and then gushes out the other end of the channel, back into the river.

Other options are more futuristic. For instance, a company called Verdant Power ran a demonstration project unlike any hydroelectric power plant in the United States. This system turned the motion of water into electricity with the help of what looked like a wind farm that got lost on its way to the field. The company built a series of triangular platforms, each dotted with several skinny poles, and each pole topped with a rotating fan, similar to the propellers on the wings of a small airplane. Then, they sunk the platforms in New York City’s East River.

As river water flowed by the poles, the blades of fans slowly turned, producing electricity. The five-turbine, 175-kilowatt pilot program spun away under the East River for nine thousand hours, off and on, between December 2006 and September 2009, providing power to a parking garage and the only grocery store on Roosevelt Island. No one generates power commercially like this today but the system is simple and effective. The company is currently in the process of building a larger system, with thirty turbines grouped into sets of six. It will have a generating capacity of 1 megawatt.

Russians regenerate flowering plant from 30,000-year-old frozen burrow of Ice Age squirrel – The Washington Post


Russians regenerate flowering plant from 30,000-year-old frozen burrow of Ice Age squirrel

By Associated Press, Published: February 20

MOSCOW — It was an Ice Age squirrel’s treasure chamber, a burrow containing fruit and seeds that had been stuck in the Siberian permafrost for over 30,000 years. From the fruit tissues, a team of Russian scientists managed to resurrect an entire plant in a pioneering experiment that paves the way for the revival of other species. 

 

The Silene stenophylla is the oldest plant ever to be regenerated, the researchers said, and it is fertile, producing white flowers and viable seeds.

41

The experiment proves that permafrost serves as a natural depository for ancient life forms, said the Russian researchers, who published their findings in Tuesday’s issue of “Proceedings of the National Academy of Sciences” of the United States.

 

(Institute of Cell Biophysics of the Russian Academy of Sciences/via AP) – A Sylene stenophylla plant has been regenerated from tissue of fossil fruit found in a squirrel burrow that had been stuck in Siberian permafrost for over 30,000 years. It is the oldest plant ever to be regenerated and it is fertile, producing white flowers and viable seeds.

 

“We consider it essential to continue permafrost studies in search of an ancient genetic pool, that of pre-existing life, which hypothetically has long since vanished from the earth’s surface,” the scientists said in the article.

Canadian researchers had earlier regenerated some significantly younger plants from seeds found in burrows.

Svetlana Yashina of the Institute of Cell Biophysics of the Russian Academy Of Sciences, who led the regeneration effort, said the revived plant looked very similar to its modern version, which still grows in the same area in northeastern Siberia.

“It’s a very viable plant, and it adapts really well,” she told The Associated Press in a telephone interview from the Russian town of Pushchino where her lab is located.

She voiced hope the team could continue its work and regenerate more plant species.

The Russian research team recovered the fruit after investigating dozens of fossil burrows hidden in ice deposits on the right bank of the lower Kolyma River in northeastern Siberia, the sediments dating back 30,000-32,000 years.

The sediments were firmly cemented together and often totally filled with ice, making any water infiltration impossible — creating a natural freezing chamber fully isolated from the surface.

“The squirrels dug the frozen ground to build their burrows, which are about the size of a soccer ball, putting in hay first and then animal fur for a perfect storage chamber,” said Stanislav Gubin, one of the authors of the study, who spent years rummaging through the area for squirrel burrows. “It’s a natural cryobank.”

The burrows were located 125 feet (38 meters) below the present surface in layers containing bones of large mammals, such as mammoth, wooly rhinoceros, bison, horse and deer.

Gubin said the study has demonstrated that tissue can survive ice conservation for tens of thousands of years, opening the way to the possible resurrection of Ice Age mammals.

“If we are lucky, we can find some frozen squirrel tissue,” Gubin told the AP. “And this path could lead us all the way to mammoth.”

Japanese scientists are already searching in the same area for mammoth remains, but Gubin voiced hope that the Russians will be the first to find some frozen animal tissue that could be used for regeneration.

“It’s our land, we will try to get them first,” he said.

Official: 4 Ohio fluid-injection wells cannot open in wake of quake – CNN.com


Official: 4 Ohio fluid-injection wells cannot open in wake of quake 

From Maggie Schneider, CNN

Sun January 1, 2012

Officials have shut down fluid-injection wells in eastern Ohio in the aftermath of heightened seismic activity in the area.

Officials have shut down fluid-injection wells in eastern Ohio in the aftermath of heightened seismic activity in the area.

 

 (CNN) – State leaders have ordered that four fluid-injection wells in eastern Ohio will be “indefinitely” prohibited from opening in the aftermath of heightened seismic activity in the area, an official said.

Ohio Department of Natural Resources Director James Zehringer had announced on Friday that one such well — which injects “fluid deep underground into porous rock formations, such as sandstone or limestone, or into or below the shallow soil layer,” the U.S. Environmental Protection Agency explains — was closed after a series of small earthquakes in and around Youngstown.

Then on Saturday, a magnitude 4.0 earthquake struck that released at least 40 times more energy than any of the previous 10 or more tremors that had rattled the region in 2011.

Andy Ware, deputy director of Ohio’s natural resources department, told CNN on Sunday that Zehringer and Gov. John Kasich subsequently ordered that four nearby injection well projects will not open in the coming weeks, as had previously been planned. They ‘ll be inoperational until a determination is made in an investigation of a possible link between the earthquakes and the fluid-injection wells, he added.

“They will (not open) until we are satisfied that the process can be safely resumed,” said Ware.

Strong earthquake strikes off Japan

Such disposal wells act as a disposal for waste fluid that is a byproduct of hydraulic fracturing, better known as fracking. That technology involves injecting water, sand and chemicals deep into the ground at high pressure to crack the shale and allow the oil or gas to flow.

Last Friday’s order affecting the first well in Youngstown came six days after a magnitude 2.5 earthquake that struck that area around 1:24 a.m. on December 24. After Saturday’s larger earthquake, scientists recommended that operations stop at all wells within a 5-mile radius of that original site.

“We need to get more information,” Ware said.

The epicenter for Saturday’s tremor was 5 miles northwest of Youngstown, 6 miles southeast of Warren and 55 miles east-southeast of Cleveland, the U.S. Geological Survey reported. According to the preliminary estimate, the earthquake struck 1.4 miles deep.

There was a lot of shaking “and a rumbling sound,” said Jimmy Hughes, a former Youngstown police chief running for sheriff of Mahoning County. “I could see the house move. … It seemed like the ground was moving. “

Ohio is far from the edges of Earth’s major tectonic plates, with the nearest ones in the Atlantic Ocean and the Caribbean Sea, the U.S. Geological Survey explains on its website. Still, there are many known faults in this region, with the federal agency noting that it is likely there are additional “smaller or deeply buried” ones that haven’t been detected.

While earthquakes are not unprecedented in the area, the rate of them in the past year has been unusual. That fact led Zehringer, the Ohio department head, to act late last week.

“While conclusive evidence cannot link the seismic activity to the well, Zehringer has adopted an approach requiring prudence and caution regarding the site,” the natural resources department said Friday in a press release, explaining its decision to shut the first well.

Ben Lupo — CEO of D&L Energy, an independent natural gas and oil exploration, production and marketing group that is affiliated with the first well that was closed — recently told CNN affiliate WKBN that there’s full cooperation with experts, though he expressed grave doubts that the injection wells were to blame for the quakes.

“We have approximately 1,000 wells between Ohio and Pennsylvania and we’ve never had a problem … with an earthquake or spill,” Lupo said.

Dr. Won-Young Kim, one of the Columbia University experts asked by the state to examine possible connections between fracking and seismic activity, said that a problem could arise if fluid moves through the ground and affects “a weak fault, waiting to be triggered.” He explained the underground waste “slowly migrates” and could cause issues miles away, adding that the danger could persist for some time as the fluid travels and seeps down toward the fault.

“In my opinion, yes,” the recent spate of earthquakes around Youngstown is related to a fluid-injection well, Kim stated — though there has been no definitive determination, by the state or other authorities, indicating as much.

There have been “moderately frequent” reports of earthquakes in northern Ohio since the first recorded one was reported in 1823, the federal agency noted. A 1986 tremor, measuring magnitude 4.8, caused some damage. Another in 1998 measured a 4.5 and was centered in northwest Pennsylvania.
