Lungs of the planet reveal their true sensitivity to global warming

Thursday, February 7, 2013

Tropical rainforests are often called the "lungs of the planet" because they generally draw in carbon dioxide and breathe out oxygen. But the amount of carbon dioxide that rainforests absorb, or produce, varies hugely with year-to-year variations in the climate. In a paper published online this week (Feb 6 2013) by the journal Nature, a team of climate scientists from the University of Exeter, the Met Office-Hadley Centre and the NERC Centre for Ecology & Hydrology, has shown that these variations reveal how vulnerable the rainforest is to climate change.

Lead author Professor Peter Cox of the University of Exeter explained: "We have been struggling for more than a decade to answer the question 'will the Amazon forest die back under climate change?' Our study indicates that the risk is low if climate change is associated with increased plant growth under elevated carbon dioxide. But if this effect declines, or climate warming occurs due to something other than a carbon dioxide increase, we expect to see a significant release of carbon from tropical ecosystems".

The study reveals a new way to find out how sensitive biological systems are to changes in climate. The key was to learn how to read the year-to-year variations in the concentration of carbon dioxide in the atmosphere. Carbon dioxide increases each year as a result of burning fossil fuels and deforestation. But the amount it goes up from one year to the next depends on whether tropical forests are absorbing carbon dioxide or releasing it ? and this in turn depends on whether the tropical climate was warmer and dryer than usual, or wetter and cooler. So the trace of carbon dioxide in the atmosphere holds a record of how the lungs of the planet respond when the climate warms or cools.

The team studied how these year-to-year variations in carbon dioxide concentration relate to long-term changes in the amount of carbon stored in tropical rainforests. They found that climate models that predicted tropical forest dieback under climate change also had a very large year-to-year variation in carbon dioxide concentration, while models in which the rainforest was more robust to climate change had more realistic year-to-year variation in carbon dioxide concentration.

By combining this relationship with the year-to-year variation in carbon dioxide as seen in the real world, the team were able to determine that about 50 billion tonnes of carbon would be released for each degree Celsius of warming in the tropics. Peter Cox said the findings were initially a relief: "Fortunately, this carbon release is counteracted by the positive effects of carbon dioxide fertilisation on plant growth under most scenarios of the 21st century, so that overall forests are expected to continue to accumulate carbon."

The researchers are however certain that tropical forests will suffer under climate change if carbon dioxide doesn't fertilise tree growth as strongly as climate models suggest.

Co-author, Chris Jones, of the Met Office said: "The long-term health of tropical forests will depend on their ability to withstand multiple pressures from changing climate and deforestation. Our research has shed light on the former, but the latter remains a significant pressure on this ecosystem."

Payday Loans Get Criticised ? Again :: The Market Oracle ...

Brent Wayne writes: Payday loans always seem to be being criticised and this time it is because there is a feeling that students are being unfairly targeted for them. A payday loan is an expensive way to borrow because it is aimed at people with a poor credit record, which may mean that they have been in debt a lot in the past or that they have no history of borrowing. It is felt that these people are the ones that are most vulnerable in society and so they should not be being targeted.


Payday loans claim to be filling a gap in the market and providing finance to those in need, where there were no solutions before. This means that someone who cannot borrow from anyone else and who is desperate for money can use this facility. The problem is, when it all spirals out of control.

If a loan is taken and then paid off when due, everything is fine. A person needs some extra money to pay a bill before pay day arrives, then pays back the money. However, the problem occurs when there is not enough money to pay the loan back. This could end up in the person either having to pay fees and having the interest build up even more or they get out another loan to pay for the original one. The first circumstance is bad enough as the debt builds up, but by speaking to the lender, a more manageable payment plan could be worked out. By getting another loan, the debt can easily get out of control as higher and higher value loans will need to be taken out to cover the cost of the loan plus interest. If this was done every month on a ?100 loan, within four months the interest could easily be higher than the amount borrowed in the first place.

Payday loan companies (like) have been criticised for not ensuring that their customers have the means to pay back the money before they allow them the loan. This is slightly unfair as most lenders, with the exception of mortgage lenders, do not do this sort of check. However, the loans are aimed at people who have shown they have not got good financial sense.

The blame could be put on the education system though. If people were taught in schools about money and how to budget, then they could better cope with it when they were older. Relying on parents, who have not had financial education, to teach their children is not going to work. Something else needs to be done, to help everyone understand more about the importance of spending money wisely.

Operator at Calif nuke plant disputes safety claim

(AP) ? The utility that runs the troubled San Onofre nuclear power plant on the California coast sharply denied Thursday that it was aware of equipment problems linked to a 2012 tube break that released a trace of radiation.

On Wednesday, Sen. Barbara Boxer pressed federal regulators to open an investigation at the plant after uncovering documents that she said suggest that Southern California Edison took engineering shortcuts and compromised safety.

The Democratic senator said in a letter to Nuclear Regulatory Commission Chair Allison Macfarlane that a confidential report obtained by her office shows Edison and Mitsubishi Heavy Industries, the Japan-based company that built the plant's steam generators, were aware of design problems before the equipment was installed in 2009 and 2010.

But Edison said in a statement "it is simply not accurate" to suggest the company was aware of design problems, and pointed out the equipment carried a 20-year warranty against defects.

"SCE would never, and did not, install steam generators that it believed would not perform safely," the company said. Edison "sought to purchase replacement steam generators that would meet or improve upon the safety standards and performance of the original steam generators."

The seaside plant located between San Diego and Los Angeles hasn't produced electricity in more than a year, after a tiny radiation leak in January 2012 led to the discovery of damage to hundreds of steam generator tubes that carry radioactive water.

Boxer, who chairs the Environment and Public Works Committee, said the report written by Mitsubishi raises concerns that Edison and its contractor rejected safety modifications and sidestepped a more rigorous safety review.

"Safety, not regulatory short cuts, must be the driving factor in the design of nuclear facilities, as well as NRC's determination on whether (San Onofre) can be restarted," Boxer said in a letter co-signed by Rep. Edward Markey, D-Mass.

In a statement, the NRC said it received the letter and "will review all available information in making a judgment as to whether the plant would meet our safety standards if restart were permitted."

Mitsubishi said design decisions were made "in accordance with well-established and accepted industry standards" along with a wealth of operating experience.

"Nothing is more important to us than the safe design and manufacturing of nuclear-energy facilities," a company statement said. "A thorough investigation has been ongoing and will continue. We will continue cooperating fully."

Boxer's disclosure further clouds the future of the twin-domed plant, which is seeking NRC permission to restart the Unit 2 reactor and run it at reduced power in hopes of slowing or halting tube damage.

The future of heavily damaged Unit 3 is not clear.

Last year, federal officials blamed a botched computer analysis for design flaws that are largely to blame for unprecedented wear in tubes at the plant. They found a Mitsubishi analysis vastly misjudged how water and steam would flow in the reactors.

Gradual wear is common in steam generator tubing, but the rate of erosion at San Onofre stunned officials because the equipment, installed in a $670 million overhaul, is relatively new.

Boxer's letter adds new weight to a longstanding ? and unresolved ? question at San Onofre. Did Edison modify the generators so extensively before they were installed that the company should have sought an amendment to its operating license, a process that can take months or even years?

Edison has long argued such an amendment was unnecessary. However, environmentalists and other critics of the nuclear power industry have claimed the company deceived the NRC about the extent of the changes and want the agency to find the company acted improperly.

Those alterations included adding 400 tubes to each generator, compared to the originals, and installing V-shaped supports that were intended to minimize tube wear and vibration. According to company documents, each of the replacement generators weighed nearly 24 tons more than the original generators.

Engineers for Edison and Mitsubishi, writing last year in a trade magazine, said they needed to design generators that would require only minor modifications within the rest of the plant, but also meet a federal test to qualify as "in-kind," or essentially identical, replacements, which would allow them to be installed without prior approval from federal regulators.

Boxer said the report documented that Edison and Mitsubishi rejected some safety modifications, apparently because they believed they could force the company to seek a lengthy license amendment. It also indicates the decision to reject additional safety modifications contributed to the faulty design, she said.

Boxer's office did not release the report.

The generators, which resemble massive steel fire hydrants, control heat in the reactors and operate something like a car radiator. At San Onofre, each one stands 65 feet high, weighs 1.3 million pounds, with 9,727 U-shaped tubes inside, each three-quarters of an inch in diameter.

Overall, NRC records show investigators found wear from friction and vibration in 15,000 places, in varying degrees, in 3,401 tubes inside the plant's four generators, two in each reactor.

The plant is owned by SCE, San Diego Gas & Electric and the city of Riverside.

EE to expand LTE coverage to 27 more markets by June

Android Central

Carrier promises 55% UK population coverage in 65 markets by mid-year

Sole UK 4G carrier EE has announced that it intends to expand its LTE coverage to a further 27 towns and cities across the country by June of this year. The move, it says, will bring 4G reception to 55 percent of the UK population in some 65 markets, up from its current 45 percent UK population coverage across 28 markets.

Between April and June, EE says it'll light up 4G in Aldershot, Ashford, Basildon, Basingstoke, Blackpool, Bracknell, Camberley, Colchester, Crawley, Farnborough, Guildford, Horsham, Huddersfield, Leatherhead, Maidstone, Milton Keynes, Oldham, Oxford, Redhill, Reigate, Sevenoaks, Stevenage, Tonbridge, Royal Tunbridge Wells, Warrington, Wigan and Woking.

With the strengthening of its LTE network, EE will be looking to make the most of its advantage in being the ony British 4G network until the middle of the year. In late spring or early summer, rival carriers like O2, Vodafone and Three will look to launch their own 4G networks, with Three promising in recent days to provide the service without hiking prices. EE currently operates its service on re-farmed 1800MHz airwaves; the ongoing 4G spectrum auction will determine how the UK's 800 and 2600MHz spectrum is divvied up.

With competition likely to intensify later in the year, 2013 looks set to become an interesting and historic year for the UK wireless industry.

Undead ahead! 7 tips for getting the most out of 'Dead Space 3'

Tip No. 1: If you're going to play "Dead Space 3," the first thing you must do: Turn down the lights. Then: Turn up the Surround Sound.

So advises Steve Papoutsis, executive producer for the newly launched horror game and a man who knows a little something about enjoying a good scare. The best-selling Dead Space franchise is filled with grotesque monsters, creepy space locales and a whole lot of mind-bending madness, and it has been scaring the space suits off gamers since the series began in 2008.

This week Dead Space returns with the third installment, and this time around it has some new twists designed to spook players both veteran and newb. There are new terror-filled locales and new monsters with all new tricks up their, uhm, barb-spewing tentacles and blade-shaped arms. Meanwhile, for the first time, two players can tackle the atrocities that lie in the cold, dark reaches of space together cooperatively.

"It's the most ambitious and largest game we?ve ever done," Papoutsis told me in a recent interview.

To help you get the most (bloodspatter?) from your "Dead Space 3" experience, I have collected the following tips from Papoutsis as well as from from my own time playing the game. Read on ... if you dare:

Tip No.2 - Get to know your Necromorphs

Playing "Dead Space 3" means playing poor tortured space engineer Isaac Clarke. As Isaac, you'll have to kill a great many undead former humans known as Necromorphs. And they come in more than one flavor. You've got your Wasters, Leapers, Exploders and Twitchers ... just to name a few. And they each have their own strengths and weaknesses.

The key: Learn their weaknesses. Fast.

Take the Lurker for example. Shooting at this creature's bulbous body is a waste of valuable ammunition. Instead, take aim above its head where its three (THREE!) barb-spewing tentacles meet. One well-placed shot with a Line Gun here and you'll sever the three tentacles clean off and be done with this terrifying business.

Tip No.3 - Stray fromthe path

If you consult Isaac's hand-dandy Locator gadget, it will tell you exactly where you need to go next in the game. But I suggest you go the exact opposite direction as often as you can. Visceral has hidden helpful goodies (ammo, materials to craft weapons and the mysterious Peng Treasure) throughout the game. But you'll need to hunt to really score the extras.

And don't just keep your eyes open for goodies. Keep your ears open too, Papoutsis says. "Dead Space 3" gives players a new Scavenger Bot to help find and retrieve hidden loot, and there's a particular audio cue that signals a good time to unleash it.

"When you hear that sound, if you deploy your Scavenger Bot, he?ll go off and scavenge around, and you have a chance of getting a much richer cache of items," Papoutsis explained.

TipNo. 4 - Use your words

If you're playing "Dead Space 3" on an Xbox and happen to own a Kinect, then here's a chance to put its voice recognition capabilities fun use. Speak a variety of voice commands and you'll see immediate results in the game. For example, say "reload weapon" or "switch weapon" and Isaac will do just that.

Meanwhile, "Dead Space 3" is the first game to use voice co-op voice commands. And that means reducing time spent fumbling with inventory. For example, if your partner needs ammo simply say "give partner ammo." In fact, here's a handy-dandy list of what to say to get what you want.

Tip No.5 - Play with a friend

When you play "Dead Space 3" in co-op mode, one of you plays as Isaac and the other plays as John Carver ? a soldier plagued by moments of terrifying dementia.

Visceral has made co-op drop in/drop out, so that you can play with a second person as long as you like and then leave when you like without losing your progress or items.

Meanwhile, if you play with a friend, you get a deeper look at the Dead Space world, access to unique missions and, most interestingly, a look at Carver's disturbing story. You also get some seriously hair-raising moments caused by his battle with own mind.

TipNo. 6 - Choose weapons wisely

With the new weapons crafting system in "Dead Space 3," players can customize weapons in many ways. And so Papoutsis suggests that, when playing with a friend, "mix and match your strategy and the upgrades on your weapons so that you complement each others? play style."

For example, one player might decide to take the lead on taking out enemies and thus choose a weapon with an attachment that maximizes damage. Meanwhile, the other player could take the support role and use an attachment that heals both players.

Tip No.7 - Pick your partner carefully

Ultimately, when it comes to playing co-op "Dead Space 3," Papoutsis said it's important to team up with someone who wants the same thing out of the game. Do you want a partner who keeps the friendly chit-chat to a minimum so you can immerse yourself in the tension-filled horror mood? Or are you looking for a fun partner to take a romp through a sci-fi epic?

"I think both can be equally fun,"said Papoutsis."You just have coordinate that with your friend."

Sochi a point of national pride for Putin's Russia

SOCHI, Russia (AP) ? One year before Russia hosts its first Winter Olympics, this Black Sea resort is a vast construction site sprawling for nearly 40 kilometers (25 miles) along the coast and 50 kilometers (30 miles) up into the mountains. After arriving at Sochi's new airport, there's no escape from the clang and clatter of the drilling, jackhammering and mixing of cement that drowns out the hum of the sea and the birdsong.

For Russia and its leadership, the 2014 Sochi Games is not just a major sports event but a point of national pride. President Vladimir Putin has made the Olympics his personal project and, determined to use them to showcase a powerful and prosperous Russia, has spared no expense to make sure the games are a success.

On Thursday, Putin will be in Sochi to preside over a lavish celebration marking the one-year countdown to the opening ceremony on Feb. 7, 2014.

"The project is under his permanent control and we enjoy the full government support," Sochi organizing committee head Dmitry Chernyshenko said. "This really is his games because he recognizes the power of these games, the greatest ever catalyst to accelerate positive change."

The current overall price tag for the games is $51 billion, more than four times as much as Russia estimated when it was awarded the Olympics in 2007. This would make Sochi the most expensive Olympics in history, surpassing the $40 billion that China is believed to have splashed out for the 2008 Summer Games in Beijing. For Sochi, at least half the money is coming from state coffers, with most of the rest being put forward by state-controlled companies and Russian tycoons.

The costs are high because they include extensive infrastructure development in addition to construction of the Olympic venues, almost all of which had to be built from scratch. Most of the sports venues have already been completed or will be in the next few months, while armies of workers are busy building hotels and additional Olympic facilities, including two of the three athletes' villages and the media center.

Almost every major street and highway is affected by road works, further snarling the traffic that can make a 25-kilometer (15-mile) ride into town from the airport take more than two hours.

The sheer scale of the construction is staggering, but the head of the local organizing committee is confident that everything will be ready for the games.

"We're building all the infrastructure right on schedule and within the budget," Chernyshenko said.

The 2014 Games, which run through Feb. 23, will feature more than 3,000 athletes competing in seven sports and 15 disciplines for a total of 98 medal events. The sports program includes 12 new events, including women's ski jumping and slopestyle snowboarding and skiing.

This city in southern Russia once seemed an unusual choice for the Winter Games. With its lush subtropical climate, Sochi was previously known only as a summer sea resort where hotels with rude Soviet-style service catered to undemanding tourists from provincial Russia. The snow-capped peaks to the northeast saw little downhill skiing, an elitist and unpopular sport in Soviet times.

But in recent years, the mountains above the city have been transformed into a modern ski resort, with cable cars, cozy chalets and new hotels. Free Wi-Fi is ubiquitous, even at 2,300 meters (7,600 feet). Russia hopes the games will put Sochi on the map as a year-round international resort.

"It's (a) once-in-a-lifetime opportunity for the country and for the entire region," Chernyshenko said. "Preparations for the games are like a magic wand. Once you've waved with it, you can really accelerate the changes and speed up all the processes."

All of the indoors sports, including figure skating, speed skating, ice hockey and curling, will be held down on the Black Sea coast in five new arenas which have already been completed. The only remaining arena to be commissioned is the Olympic Stadium, where the opening and closing ceremonies will be held.

This winter and spring, Sochi is hosting 22 test events at the same venues where the Olympic athletes will compete next year.

Cross-country skiers who took part in a test event last weekend praised the courses but said they were taken aback by the high level of security.

"I've never been in a place where there's this much security, this many security officers, this many checkpoints," said Noah Hoffman, a member of the U.S. cross-country ski team. "It's twofold: It makes you feel very safe, but at the same time it's a little bit of a hassle. I don't know if there's a big security threat here, but they certainly have everything under control."

From the entrance to the cable car at the foot of the mountain to the slopes at the top, security guards and volunteers checked credentials every step of the way. Athletes, journalists and the few spectators who attended the test events were stopped when getting onto a shuttle bus or snowmobile, and again when they arrived at their destination. During a single journey, it wasn't unusual for a badge to be meticulously scrutinized at least a dozen times.

Guards with assault rifles and German shepherds patrolled the sports venues in groups, although they did not approach visitors and seemed to try to keep a low profile.

Chernyshenko said the security measures would be exactly the same during the games and insisted that they were no different from those taken at past Olympics held elsewhere in the world.

Russia is wary of an Islamic insurgency that has long troubled a patchwork of predominantly Muslim republics located on the other side of the mountain range. The insurgency began in Chechnya during separatist wars with Moscow in the 1990s and spread throughout the region. In Dagestan, the current epicenter of the violence, bombings and shootings targeting police and other officials occur almost daily. In recent years, however, the terror attacks have largely been confined to the North Caucasus region, rarely spilling out into the rest of Russia.

To the south of Sochi along the Black Sea coast lies Abkhazia, a breakaway part of Georgia allied with Russia, which has troops stationed there. Georgia lost its last remaining bit of territory in Abkhazia during a brief war with Russia in 2008. Relations between Russia and Georgia are only now beginning to thaw.

"I can assure you that law enforcement agencies are taking unprecedented measures to protect our tourists from any danger," Sochi Mayor Anatoly Pakhomov said. "I'm confident that our Olympics are going to be the safest ones ever."

Another concern for Sochi is the weather. The snowfall this winter has been abundant, but the Russians have made contingency plans in light of the warm weather and rain that disrupted some of the freestyle skiing and snowboarding events at the 2010 Vancouver Games.

The Rosa Khutor resort, which will host the Alpine skiing and other events, has one of the biggest snow-making systems in Europe, according to its managing director, Alexander Belokobylsky. The resort has two water reservoirs and 400 snow generators installed along the slopes. Rosa Khutor also stores snow through the summer, keeping it packed and under a tight insulated cover, and plans to store 150,000 cubic meters (195,000 cubic yards) of snow for the games.

The Olympic village for athletes competing in Alpine skiing is still under construction, as is the one for skaters and other athletes who will be based on the coast. The third Olympic village, however, is close to completion and housed the cross-country skiers during the weekend's test events.

Hoffman was impressed by the spaciousness of the rooms in the chalet where he stayed, but his first shower sent water streaming into the room below. Even though workmen arrived to fix the plumbing, he decided not to use the shower for fear it might leak again.

His American teammate, Jessie Diggins, whose room was directly under Hoffman's, said such glitches are nothing to worry about.

"Everywhere you go there's going to be one or two little kinks, nothing is going to be perfect, but I think they'll be done," Diggins said. "It's really impressive how fast they were able to put together all this infrastructure. I think with one year to go we'll have even more."

British home improvement giants to banish bee-harming products ...

In the wake of a major victory for European environmental organizations, two of the U.K.?s leading home improvement retailers, B&Q and Wickes, have pledged to halt the sale of products containing nicotine-based insecticides that have been linked by researchers to a dramatic population decline among the insect world?s most prolific pollinators.

?

Both retailers announced earlier this week that any gardening products containing neonicotinoids, a relatively new family of chemical nerve agents recently identified by the European Food Safety Authority as having a detrimental effect on bees, will be pulled from store shelves. In the case of B&Q, one product containing the widely used imidacloprid will be yanked while Wickes will remove any consumer pesticide products containing thiamethoxam. According to The Guardian, these two compounds along with a third neonicotinoid called clothianidin are believed to be a threat to struggling bee populations.

?

Bayer CropScience, the agrochemical subgroup of German aspirin giant and former heroin pusher?Bayer AG, is the primary manufacturer of?neonicotinoid products.

?

Although the crucial winged critters have nabbed stateside headlines in recent months for terrorizing unsuspecting?New Yorkers and Canadian homeowners alike, Colony Collapse Disorder remains a very real threat with neonicotinoids and other pesticides fingered as one of the many factors that play a role in the spread of the damaging ??damaging not only to the bees themselves but to agricultural operations across North America and Europe ? and somewhat mysterious phenomenon?along with environmental stressors, poor nutrition, and the spread of the parasitic varroa mite. Some studies have concluded that?neonicotinoids are the culprit behind CCD.?

?

Said a spokesperson for B&Q following the company's announcement:

?

We have been watching the debate that is developing about the use of pesticides, in particular neonicotinoids, and their potential effect on the UK bee population. Whilst we believe that the vast majority of pesticides are not injurious to bees when used in accordance with the instructions, we have some concerns about the potential for harm to be caused by the unintentional misuse of products containing imidacloprid. In recent years, this active ingredient has been phased out of many retail products, and we currently sell only one garden insecticide that uses this active. As a result of our assessment, we have decided to withdraw it from sale and are investigating alternative treatments to meet customer needs.

?

Andrew Pendleton of?Friends of the Earth, one of the organizations that pushed for the ban of neonicotinoids, had this to say:

?

We are delighted [the two retailers] are withdrawing these pesticides. Other retailers must follow suit and take action to protect our bees. The spotlight now falls on the UK government. Ministers must help safeguard our beeds by immediately suspending the three pesticides identified by European food safety scientists, and ensuring farmers have safe alternatives. Declining bee numbers are a real threat to food production.

?

Upon the EFSA?s landmark announcement earlier this month that neonicotinoids do indeed pose an ?unacceptable? threat to bees, Pendleton claimed that ?this is a major turning point in the battle to save our bees. EFSA have sounded the death knell for one of the chemicals most frequently linked to bee decline and cast serious doubt over the safety of the whole neonicotinoid family.?

?

Despite continuously mounting pressure from beekeepers and environemental groups, it appears that the US Environmental Protection Agency is a long ways off from banning neonicotinoids in both commercial agriculture applications and in home gardening products although it does recognize pesticide poisoning as one of the many potential causes of CCD and is currently re-evaluating the insecticide. France, Germany, Slovenia, and Italy have all temporarily or permanently suspended the use of neonicotinoids.

?

More over at The Guardian on the recent announcement. Fast Company also has a fantastic, in-depth article from 2010 detailing the stateside push to remove neonicotinoids from the market.?
