Facebook hits new low after price target cuts

(Reuters) - Shares of Facebook Inc fell 4.5 percent to a new low on Friday after brokerages cut their price targets on the company's shares, saying several lock-up expirations over the next year will weigh on the stock.

Early investors got the green light to sell Facebook shares for the first time on August 16, sending its stock down 6.3 percent and prompting price target cuts.

About 243 million shares will become available for trading from mid-October, with November 14 being the big day when more than 1.2 billion shares will enter the market.

The company's current free float is about 628 million shares.

'We expect investor attention to return to fundamentals after the technical challenges presented by lock-up expirations over the next six months have been absorbed by the stock,' BMO Capital Markets analysts said in a note.

They added that Wall Street sentiment on Facebook is now much worse than advertiser sentiment.

The brokerage cut its price target by $10 to $15, 60 percent below the price at which the company's stock started trading on May 18.

Media reports said BofA Merrill Lynch, an underwriter to the IPO, cut its price target by $12 to $23.

The company's shares fell to $18.23 on the Nasdaq on Friday amid heavy trading.

Shares of game publisher Zynga Inc , which gets most of its revenue from Facebook, slipped 3 percent on the Nasdaq.

Spineless creatures under threat, from worms to bees: study

OSLO (Reuters) - The vital tasks carried out by tiny 'engineers' like earthworms that recycle waste and bees that pollinate crops are under threat because one fifth of the world's spineless creatures may be at risk of extinction, a study showed on Friday.

The rising human population is putting ever more pressure on the 'spineless creatures that rule the world' including slugs, spiders, jellyfish, lobsters, corals, and bugs such as beetles and butterflies, it said.

'One in five invertebrates (creatures without a backbone) look to be threatened with extinction,' said Ben Collen at the Zoological Society of London (ZSL) of an 87-page report produced with the International Union for Conservation of Nature.

'The invertebrates are the eco-system engineers,' he told Reuters. 'They produce a lot of the things that humans rely on and they produce them for free.'

The report said that invertebrates, creatures that have no internal skeleton, faced loss of habitat, pollution, over-exploitation and climate change.

The 'services' they provide - helping humans whose growing numbers threaten their survival - include water purification, pollination, waste recycling, and keeping soils productive. The value of insect pollination of crops, for instance, has been valued at 153 billion euros ($191 billion) a year, it said.

A 1997 study put the global economic value of soil biodiversity - thanks to often scorned creatures such as worms, woodlice and beetles - at $1.5 trillion a year.

ROMAN EMPERORS

Other services include seafood from mussels and clams, silk spun by worms and the purple dyes from a type of snail that were used exclusively in the robes of Roman emperors.

The study said the level of threat was similar to that facing vertebrates - creatures with internal skeletons - including mammals like blue whales and lions as well as reptiles and birds. A 2010 IUCN study found that one fifth of vertebrates were at risk.

Collen said people have wrongly tended to ignore spineless creatures, thinking of them as small, abundant and invulnerable to human pressures. Until now, conservation spending has focused on high-profile species such as eagles, tigers and polar bears.

'This report tries to put invertebrates on the map,' he said. Invertebrates make up almost 80 percent of the world's species.

The report focused on the current state of the planet. The projected increase in the world's human population to 9 billion by 2050 from 7 billion now and other factors such as man-made climate change could make things worse for invertebrates.

The report, which assessed 12,000 species in the IUCN's Red List of endangered species, called for a switch to 'green accounting' to ensure that the benefits of services provided by small creatures are built into national accounts such as GDP.

China Tops U.S. In Renewable Energy Rankings

According to the analysts at Ernst & Young , China continues to top the U.S. in the creation of green jobs and innovation in matters of renewable energy and Germany is also coming on strong with its own renewable energy agenda. The renewable industry, particularly wind, faces some global challenges, however. Here are the details.



* Ernst & Young's August 2012 renewable energy country attractiveness indices provides scores for countries based on their national renewable energy markets, renewable energy infrastructures and their suitability for individual technologies.



* According to the study, the U.S. is dealing with policy gridlock due to the upcoming elections and "policy-makers have yet to demonstrate the appetite to make long-term investment decisions that would necessitate short-term cost increases."



* The UK, Spain and Italy are also struggling with growth in the renewable energy industry due to credit crises and a lack of clarity for investors.



* Germany is pushing ahead with an ambitious renewables agenda, Ernst & Young reports, tying for second place with the U.S. in the renewable energy attractiveness indices. The country has introduced a midsize rooftop tariff and is compensating for losses caused by delays in offshore grid connection.



* According to the study, Asian countries have risen to the forefront of green job creation. China, for example, has quadrupled its solar capacity target to 50 GW by 2020 and Chinese policy-makers are addressing the oversupply of solar panels with accelerated domestic installations.



* Ernst & Young reports that the wind industry will see a challenging next couple of years due to the expiration of the U.S. Production Tax Credit (PTC) at the end of 2012. Developers are holding off on new activity until they find out whether the PTC will be secured.



* In China, wind energy activity is also on a decline due to governmental restrictions put in place to prevent overcapacity and grid bottlenecks. The Chinese wind market peaked at the end of 2011 at 20 GW and is predicted to settle over the course of the decade at about 15-17 GW per year.



* Ernst & Young reported that the imposition of duties of 73 percent and 60 percent on wind towers imported from China and Vietnam, respectively, as well as the anti-subsidy and anti-dumping tariffs imposed on solar imports, will provide some short-term relief to U.S. wind and solar manufacturers. However, a failure of Congress to pass the tax credits would negate any benefits that the duties and tariffs might have.



* The U.S. solar sector also faces uncertainty as congress debates the face of the Department of Energy's loan guarantee program with a Republican-backed bill that would phase out the program. The "No More Solyndras" bill has passed the House Energy and Commerce Committee's energy and power subcommittee and is now in the hands of the Senate, Ernst & Young reported.

Protect Privacy When Recycling Smartphones

Click here to listen to this podcast

If you're thinking about upgrading to Apple's new iPhone 5 when it debuts in a few weeks, you're going to have to figure out what to do with your current device. Given how much we've come to rely on these gadgets for storing pictures, contacts and personal information, some serious privacy issues should be considered before selling, recycling or trading in your old phone.

Typically, you restore factory settings on your smartphone before parting ways. But a couple of recent articles on NBCNews.com and Yahoo.com find that factory resets are inconsistent, depending on the phone.

Blackberry and Apple resets appear to delete and scrub personal data the best, according to data retrieval experiments described in the articles. But Android and Microsoft smartphones weren't as good at wiping important information.

In the Yahoo article computer analyst Steve Burgess recommends that, in addition to the factory reset, you should remove a phone's memory and SIM cards before turning it in. Robert Siciliano's advice in the NBCNews.com story was a bit more severe. He recommends a drill, a sledgehammer and bucket of salt water.

Beyond Wind & Rain: Isaac Could Stir Up Oil

As Tropical Storm Isaac roars over Louisiana and elsewhere on the Gulf Coast, it threatens to disrupt a fragile environment that's still recovering from BP's Deepwater Horizon oil spill in the summer of 2010.

By disturbing the sediments in which the spilled oil is buried, near the beach and deeper in the water, the hurricane could release large quantities of oil, several researchers warn.

'This is another disaster on top of the hurricane that we're going to have to deal with,' Garret Graves, chairman of Louisiana's Coastal Protection and Restoration Authority, told the Huffington Post. 'The threat is not insignificant.'

So far there have been no reports of oil, but that isn't surprising considering most everybody is taking shelter or has evacuated the area, said Lt. Alyssa Johnson, operation officer at the National Response Center, a federal organization responsible for coordinating a response plan to environmental releases of oil or other hazardous materials. [Latest News on Isaac]

Storm surge

Isaac's storm surge, expected to reach heights of 6 to 12 feet (about 2 to 3.5 meters), could transport oil inland, where it could further affect marshlands and wildlife or come into contact with people, Graves told the Bloomberg news service. It also could flood areas containing contaminants such as pesticides, fertilizers and septic system bacteria and wash these back out into coastal waters or into groundwater, University of Florida researcher Andrew Zimmerman told OurAmazingPlanet in an email.

But it's unclear how much oil remains in Gulf sediments and along the shoreline - and how much might be stirred up.

'It could be a lot or a little,' said University of Florida researcher Andrew Zimmerman.

An estimated 1 million gallons of MC 252 oil from the Deepwater Horizon spill has been distributed throughout the sediment underwater, on the beach and in marshes, according to Nanciann Regalado, speaking a spokesperson at the U.S. Department of the Interior.

'After danger to humans has passed and field teams can get into the field, samples of oil that has been exposed will be taken,' Regalado told OurAmazingPlanet. If chemical analysis finds that the oil was from the Deepwater Horizon, BP may be required to clean up the oil, she added.

Exactly how far below the surface sediment and oil can be disturbed by a hurricane isn't clear, but meteorologist Jeff Masters said large hurricanes can create currents capable of mobilizing whatever oil is at the bottom.

Nick Shay, a professor of meteorology and physical oceanography at the University of Miami, told the Huffington Post this was possible. Hurricanes can 'bring whatever is near the bottom up higher in the water column, and currents can then push it towards the coast,' he said.

Erosion

Isaac also could worsen erosion in the area by pounding the shore with waves. According to the National Hurricane Center, Isaac is likely to cause significant erosion of 89 percent of Mississippi's beaches.

The Deepwater Horizon disaster began with a deadly blowout on April 20, 2010, and spilled an estimated 205 million gallons of crude into the Gulf. Among other damage, the oil killed marsh grasses that prevent erosion. For 18 months afterward, marsh erosion rates doubled to 10 feet (3 meters) per year, said University of Florida researcher Brian Silliman.

Most of the grass has grown back, but how it will weather this storm is unclear. Barrier islands and coastlines could be eroded, affecting nesting areas for many kinds of wildlife, including birds and turtles.

Biggest impact

The biggest environmental impact of Isaac will be erosion causing the loss of wetlands, Masters said. A 2011 study by the United States Geological Survey found that four hurricanes in the past seven years - Katrina, Rita, Gustav and Ike - together destroyed about 250 square miles (650 square kilometers) of Louisiana. 'I expect Isaac will destroy 50-100 square miles of wetlands,' or about 130 to 260 square kilometers, Masters told OurAmazingPlanet.

A spokesman for BP said the company isn't worried about Isaac. 'Consistent with the past two hurricane seasons, we do not expect any significant impact of residual MC 252 oil following Hurricane Isaac,' Ray Melick told the Huffington Post.

Although plants and animals are well-adapted to storms like this, Zimmerman said, they have a lowered ability to cope when they are already stressed from human activities.

Luckily, Regalado said, bird nesting season in the area is largely finished and most wintering birds haven't arrived. However, loggerhead sea turtle nesting season is in full swing, and many nests are at risk of flooding.

DOE Gives $10 Million to University-Led Concentrating Solar Projects

The U.S. Department of Energy has announced that it will provide $10 million over the next five years for two university-led projects that focus on new concentrating solar power technologies. Here are the details.



* Concentrating solar power technologies use mirrors to reflect and concentrate sunlight, the DOE explained. Receivers then collect the solar energy and convert it to electricity-producing heat.



* According to the DOE, a key component to concentrating solar power systems is heat transfer fluids that carry the heat from a receiver to the point where the heat is needed to drive a turbine.



* The two projects that have been funded by the department's SunShot Initiative both focus on improving heat transfer fluids.



* One of the teams is led by the University of California-Los Angeles. Researchers from Yale University and the University of California-Berkeley will also be participating in an investigation into liquid metals as potential heat transfer fluid that can withstand higher temperatures.



* A research team from the University of Arizona, along with researchers from Arizona State University and Georgia Tech, is planning to develop and demonstrate new molten salt-based fluids that could possibly be used as alternatives to traditional heat transfer fluids, the DOE reported.



* Today's heat transfer fluids are able to operate at temperatures up to about 1,050 degrees Fahrenheit. According to the DOE, the selected projects will develop heat transfer fluids that can operate at temperatures of up to 2,350 degrees Fahrenheit.



* The DOE's SunShot Initiative operates under the goal of reducing the total cost of solar energy systems by 75 percent by the end of the decade, which will make it cost-competitive with conventional forms of electricity, the department states.



* In order to drive innovation, the DOE states, it will support the efforts of private companies, academia and national laboratories to come up with ways to reduce the cost of solar electricity down to about $.06 per kilowatt-hour.



* The SunShot Initiative projects, selected by the DOE, are refered to as high-risk, high-payoff concepts that can advance a clean, low-cost, large-scale energy source for home owners, communities, business and governmentment, the department stated.



* In June, the DOE announced $56 million of funding over three years for 21 projects that seek to improve concentrating solar power technology performance.



* Several of those projects also research various possibilities for heat transfer fluids, including the National Renewable Laboratory's project that will test the use of falling particles instead of liquid for the heat transfer fluid.

In Arctic, Greenpeace picks new fight with old foe

STOCKHOLM (AP) - Global warming has ignited a rush to exploit Arctic resources - and Greenpeace is determined to thwart that stampede.

Employing the same daredevil tactics it has used against nuclear testing or commercial whaling, the environmental group is now dead-set on preventing oil companies from profiting from global warming by drilling for oil near the Arctic's shrinking ice cap.

The campaign took off in May 2010, when oil was still gushing from a ruptured well in the Gulf of Mexico. At the time, Greenpeace was startled by reports that a small Scottish energy firm was proceeding with plans to drill for oil and gas in iceberg-laden waters off western Greenland.

'It felt slightly surreal,' recalled Ben Ayliffe, now the head of Greenpeace's campaign against oil drilling the Arctic. 'After what happened in the Gulf of Mexico, how can anyone respond to that by going to drill in similar depths in a place called Iceberg Alley?'

Greenpeace quickly arranged to get a ship to Greenland, where four activists attached themselves to a drilling rig for two days until a storm forced them to abandon the protest.

That stunt, a similar one in 2011 off Greenland and protests this month at an oil rig off northwest Russia are at the core of what Greenpeace calls 'one of the defining environmental battles of our age.'

'Polar work feels like it's going back to the early campaigns: simple message, people get it and the lines are very clearly drawn,' Ayliffe said.

From a publicity standpoint, the campaign has been successful: Greenpeace officials say since June, 1.6 million people have signed the group's online petition urging world leaders to declare the Arctic a global sanctuary, off limits to oil exploration and industrial fishing. Dozens of celebrities, including Robert Redford, Paul McCartney and Penelope Cruz have announced their support, according to Greenpeace activist Sarah North.

'I have never experienced engaging famous people at this kind of rate and with such ease in a campaign issue,' said North, a 15-year veteran at Greenpeace.

The impact on the oil industry, however, is unclear. The Arctic is believed to hold up to a quarter of the world's undiscovered oil and gas reserves. Despite difficult operating conditions and high costs, the payback for Shell, Gazprom, Statoil and other companies searching for commercial quantities of hydrocarbons could be huge.

'It probably sounds a bit cynical, but if they invest billions of dollars it's not likely they will give it up just because somebody is attacking their oil rig,' said Mikhail Babenko, an oil and gas expert at the World Wildlife Fund's Global Arctic Program.

Unlike Greenpeace, WWF isn't seeking a complete ban on drilling in the Arctic but wants to make sure the most vulnerable areas are protected.

'We want to be part of this discussion,' Babenko said. 'We don't want to stimulate oil and gas development, but if we follow (Greenpeace's) approach we will be simply out of the game.'

Greenpeace and other environmental groups say an oil spill in the Arctic could cause irreparable damage to wildlife and marine ecosystems.

Fears that the oil industry is ill-prepared to operate in the hostile conditions of the high north were reinforced last December when a floating oil rig capsized off eastern Russia, killing more than 50 workers. While that accident happened outside the Arctic region, it underscored the challenges of drilling further north, where ice ridges are meters (yards) deep and storms are frequent.

Oil industry officials say they are taking the necessary precautions to conduct safe operations in the Arctic.

Cairn Energy, the Scottish company whose platforms off Greenland were targeted by Greenpeace protests in 2010 and 2011, isn't drilling there this year. By all accounts, that has nothing to do with Greenpeace but to the fact that the initial drilling was unsuccessful.

Asked what, if any, impact the Greenpeace actions had on the company's future plans for Greenland, Cairn spokeswoman Linda Bain referred to its second-quarter report, which doesn't say anything about Greenpeace.

Shell, which has also come into Greenpeace's cross-hairs for plans to drill off Alaska, also refused to discuss the group. Still, there's no doubt that Shell takes Greenpeace's Arctic campaign seriously.

In March, Shell won an injunction by a U.S. judge ordering Greenpeace to stay 1 kilometer (.6 miles) away from its drilling rigs in U.S. territorial waters.

A month earlier, New Zealand actress Lucy Lawless of the TV series 'Xena: Warrior Princess' and six other Greenpeace activists had climbed aboard one of the drilling rigs before it left for Alaska. They later pleaded guilty to trespass charges and are awaiting sentencing.

Greenpeace activists also climbed aboard icebreakers contracted by Shell as they left the Baltic Sea. And the Greenpeace ship 'Esperanza' is now shadowing Shell's drilling vessels as they head north to bore exploratory wells in Alaska's Chukchi and Beaufort Seas.

'We will follow the oil industry into the Arctic,' Ayliffe said. 'This is such an important campaign. We're not going to let them off the hook that easily.'

Founded in 1971, Greenpeace initially focused on nuclear testing. Its first Rainbow Warrior ship was sunk in New Zealand's Auckland harbor before it set out to protest French nuclear testing at Muroroa Atoll. Greenpeace photographer Fernando Pereira drowned.

The group claims its actions helped bring about the nuclear test ban treaty as well as a ban on dumping toxic chemicals into the ocean. It also takes credit for forcing Apple and other major companies to become more ecologically responsible.

In the 1990s, Greenpeace campaigned for years to persuade oil companies to bring disused offshore installations to land for recycling, instead of dumping them in the ocean.

The Arctic campaign is part of the group's overarching focus on climate change.

On Friday, six Greenpeace activists, including executive director Kumi Naidoo, spent several hours hanging off the side of the Prirazlomnaya platform in Russia's Pechora Sea, attached to the rig's mooring lines. Three days later, more than a dozen activists intercepted a ship carrying Russian oil workers to the platform and chained themselves to its anchor.

While Greenpeace is sometimes accused of being 'alarmist,' environment and climate activists in general applaud the group for calling attention to global warming issues. Their activities don't always resonate well, however, with some of the indigenous communities in the Arctic.

The Inuit seal hunters of Greenland, for example, blame Greenpeace campaigns against seal hunting for nearly wiping out the demand for seal skins, a key part of their income.

Ove Karl Berthelsen, Greenland's minister for oil and minerals, said he was skeptical of Greenpeace's claims to be acting in defense of indigenous communities.

'People here see through it,' Berthelsen said. 'Their star is not very high up here.'

New Java 7 exploit can be used to compromise Windows, Mac OS X or Linux computers

A vulnerability in the latest Java 7 runtime has been discovered that can be exploited and used for malicious attacks, Computer World reported. While all the reported exploits thus far have targeted Windows PCs, according to Errata Security CTO David Maynor, both Mac and Linux computers are just as vulnerable to attacks. "This exploit works on OS X if you are running the 1.7 JRE [Java Runtime Environment]," said Maynor, who was able to exploit the vulnerability in both Firefox 14 and Safari 6 on OS X 10.8. The exploit is considered "super dangerous" and could compromise a computer simply by browsing a malicious or hacked website.Computer World suggests that users disable Java until Oracle (ORCL) releases a patch to address the problem.

Australia to link with EU carbon scheme from 2015

Australia announced Tuesday it will link its hard-fought carbon pricing scheme, aimed at combating climate change, with the European Union's from mid-2015.

Australia introduced the first stage of its plans to put a price on carbon dioxide pollution in July with a so-called 'carbon tax', which charges big polluters Aus$23 (US$23.81) per tonne for their emissions of the gas.

The government has always said it would move to an emissions trading scheme after three years with a floating price set by the market. Climate Change Minister Greg Combet said this would be linked to the EU's scheme from 2015.

'This means that from July 1, 2015, Australia's carbon price will effectively be the same as that that operates in our second largest trading bloc,' he told reporters.

A full two-way link in which there would be mutual recognition of carbon units between the two cap and trade systems would begin no later than July 1, 2018, he added.

The minister said a previous commitment to set a floor price of Aus$15 per tonne for the first three years to avoid price shocks would be scrapped.

'We now look forward to the first full inter-continental linking of emission trading systems,' European Commissioner for Climate Action, Connie Hedegaard, said in a joint statement with Combet.

Combet said he was confident of Australian government modelling, which predicts a Aus$29 a tonne carbon price in 2015-16. The current EU price is below Aus$10.

The issue of a carbon tax has been hotly debated in Australia, among the world's worst per capita polluters due to its reliance on coal-fired power and mining exports.

Prime Minister Julia Gillard's popularity has sunk since she announced plans for the carbon tax in early 2011 -- after pledging before her 2010 election that it would not be introduced by a government she led.

The policy backflip prompted protests around the country against the carbon tax and conservative opposition leader Tony Abbott, who opinion polls suggest will win the 2013 election, has vowed to abolish it.

How to Set Up the Best Workspace for Homework

During the summer, my kids and their friends enjoy using technology for fun and games. But as the summer ends, it is time for me, and them, to get serious about a home technology setup that supports the dreaded 'H' word: Homework. With the right environment, kids can more easily transition from the fun of summer to the rigors of school and put their technology to work. Here are the five main components of setting up a home technology workspace for students of any age.

1. Tablets, Laptops, and Desktops

With countless options available, choosing the device best suited for your child's homework can be overwhelming. My philosophy has been to buy on an 'as needed' basis and not overwhelm my kids with options. When my kids were young, they had access to a desktop that was in a public family area. When my oldest turned 12, he needed a laptop for school projects. He then developed a passion for filming and editing video, both as a hobby and for school reports. That required a more powerful desktop computer. When his little brothers started getting assignments online, they inherited the old laptop. Our plan is to one day replace them with something like an Ultrabook, a very thin and light laptop that boots up quickly, includes SSD drives and has long battery life.

2. Ergonomics

The first step in creating a student workspace at home is finding a well-lit location. This allows for projects, paperwork, and supplies to be spread out, while living in harmony with technology. Proper ergonomics, including sitting position and distance to the keyboard, help to avoid physical strains. Desktops also force kids who like typing in bed to sit in a chair at a desk and exercise better posture (that was our reasoning... and it worked!).

A laptop workspace with a full size wireless keyboard, mouse and monitor can provide laptops the same comfort as a desktop for longer homework assignments. For those kids determined to do homework on their bed (or the living room floor, or the lawn...) a lapdesk with a thick heat shield coating really comes in handy. Some kids prefer using tablets for reading, in which case any comfortable spot will do provided the lighting doesn't cause eye strain on glaring, glossy, high resolution screens. Tablets also have numerous dock and case options that offer a sturdy position to touch and view as well as wireless keyboards to type.

3. Wi-Fi and Parental Controls

Wireless routers help spread the Wi-Fi love throughout the house for families with multiple computers and tablets. If your house has Wi-Fi dead spots, such as a room in the back of the house that is far from the router, then a Wi-Fi booster can help extend coverage.

Some parents separate 'gaming areas around the house from 'homework' areas and it's an idea with merit. In my house, even the most disciplined child cannot resist the draw of a gaming console nearby while doing math problems and grammar worksheets. Similarly, there are also many ways a kid can surreptitiously play games or use social networks online during what should be homework time. Solutions include setting internet time limits using the house's wireless router as well as using the operating system's parental controls. These system settings, along with SafeSearch settings on browsers, will help make sure kids are not visiting inappropriate sites. Of course, no amount of software can replace having a family talk about homework time versus social and gaming time on electronics.

If multiple devices are accessing the internet, home bandwidth may suffer and response time may slow. To prepare for the onslaught of internet use, it may be a good idea to check with your internet service provider to verify if your bandwidth is appropriate for your planned number of multiple devices. New wireless routers also offer features such as cloud storage, ports for backup drives, improvements in speed and media switching to prioritize high demand services such as video streaming.

4. Tech Accessories and Peripherals

Some kids like to listen to music while they do their homework, so wireless speakers or speaker docks that charge will allow kids to stream their music while they study algebra, Hemingway or chemistry. When siblings share a workspace, some good noise-cancelling earphones can help dual music tastes co-exist in close quarters. To round out the homework spot, add an all-in-one wireless printer. That will let kids print from any device in the house and scan class handouts into electronic form. For kids who plan to scan a large volume of documents, a dedicated wireless scanner can handle multiple documents of different sizes across devices and store them in the cloud. Another handy back to school tech accessory - a graphing calculator for math and science class.

5. Storage

With schools now using the cloud to store homework assignments and so many cloud storage options available, families can join the parade and use this technology as well to access media from any device. Backup drives, some that can also stream media wirelessly, are helpful for storing files like the videos my oldest son creates for his school presentations. Media and data storage heavy households may want to look into installing a dedicated home media streamer or cloud server. For simple mobile storage, kids may also need a 2-8 GB USB drive that can be personalized with designs such as Star Wars to give your little Stormtroopers the tools they need to succeed at school.

These are the building blocks of a tech and mobile ready workspace for any student. What type of tech workspace do you have (or want to design) in your home?

Climate landmark as Arctic ice melts to record low

The sea ice in the Arctic Ocean has melted to its smallest point ever in a milestone that may show that worst-case forecasts on climate change are coming true, US scientists said.

The extent of ice observed on Sunday broke a record set in 2007 and will likely melt further with several weeks of summer still to come, according to data from the National Snow and Ice Data Center and the NASA space agency.

The government-backed ice center, based at the University of Colorado at Boulder, said in a statement that the decline in summer Arctic sea ice 'is considered a strong signal of long-term climate warming.'

The sea ice fell to 4.10 million square kilometers (1.58 million square miles), some 70,000 square kilometers (27,000 square miles) less than the earlier record charted on September 18, 2007, the center said.

Scientists said the record was all the more striking as 2007 had near perfect climate patterns for melting ice, but that the weather this year was unremarkable other than a storm in early August.

Michael E. Mann, a lead author of a major UN report in 2001 on climate change, said the latest data reflected that scientists who were criticized as alarmists may have shown 'perhaps too great a degree of reticence.'

'I think, unfortunately, this is an example that points more to the worst-case scenario side of things,' said Mann, director of the Earth System Science Center at Penn State University.

'There are a number of areas where in fact climate change seems to be proceeding faster and with a greater magnitude than what the models predicted,' Mann told AFP.

'The sea ice decline is perhaps the most profound of those cautionary tales because the models have basically predicted that we shouldn't see what we're seeing now for several decades,' he added.

Arctic ice is considered vital for the planet as it reflects heat from the sun back into space, helping keep down the planet's temperatures.

The Arctic region is now losing about 155,000 square kilometers (60,000 square miles) of ice annually, the equivalent of a US state every two years, said Walt Meier, a scientist at the National Snow and Ice Data Center.

'It used to be the Arctic ice cover was a kind of big block of ice. It would melt a little bit from the edges but it was pretty solid,' Meier told reporters on a conference call.

'Now it's like crushed ice,' he said. 'At least parts of the Arctic have become like a giant slushie, and that's a lot easier to melt and melt more quickly.'

The planet has charted a slew of record temperatures in recent years, with 13 of the warmest years ever taking place in the past decade and a half, along with extreme weather ranging from severe wildfires in North America to major flooding in Asia.

Researchers have also reported a dramatic melt this summer on the ice sheet in Greenland, which could have major consequences for the planet by raising sea levels.

Scientists believe that climate change is caused by human emissions of carbon and other greenhouse gas emissions.

But efforts to regulate emissions have faced strong political resistance in several nations including the United States, where industry groups have said that regulations would be too costly for the economy.

Kumi Naidoo, the executive director of Greenpeace who on Monday intercepted a Russian ship in the Arctic, said the ice melt showed that the planet was 'warming up at a rate that puts billions of people's future in jeopardy.'

'These figures are not the result of some freak of nature but the effects of man-made global warming caused by our reliance on dirty fossil fuels,' he said in a statement.

Shaye Wolf of the Center for Biological Diversity pressure group called the record ice melt 'a profound -- and profoundly depressing -- moment in the history of our planet.'

The melt has rapidly changed the politics and economics of the Arctic region, with shipping companies increasingly eager to save time by sailing through the once-forbidding waters.

Data released Monday by the Washington-based Center for Global Development found that nations including China, India and the United States were reducing the intensity of their carbon emissions but that the effort was overwhelmed by the surge in power consumption in developing nations.

In climate landmark, Arctic ice melts to record low

The sea ice in the Arctic Ocean has melted to its smallest point ever in a milestone that may show that worst-case forecasts on climate change are coming true, US scientists said Monday.

The extent of ice observed on Sunday broke a record set in 2007 and will likely melt further with several weeks of summer still to come, according to data from the National Snow and Ice Data Center and the NASA space agency.

The government-backed ice center, based at the University of Colorado at Boulder, said in a statement that the decline in summer Arctic sea ice 'is considered a strong signal of long-term climate warming.'

The sea ice fell to 4.10 million square kilometers (1.58 million square miles), some 70,000 square kilometers (27,000 square miles) less than the earlier record charted on September 18, 2007, the center said.

Scientists said the record was all the more striking as 2007 had near perfect climate patterns for melting ice, but that the weather this year was unremarkable other than a storm in early August.

Michael E. Mann, a lead author of a major UN report in 2001 on climate change, said the latest data reflected that scientists who were criticized as alarmists may have shown 'perhaps too great a degree of reticence.'

'I think, unfortunately, this is an example that points more to the worst-case scenario side of things,' said Mann, director of the Earth System Science Center at Penn State University.

'There are a number of areas where in fact climate change seems to be proceeding faster and with a greater magnitude than what the models predicted,' Mann told AFP.

'The sea ice decline is perhaps the most profound of those cautionary tales because the models have basically predicted that we shouldn't see what we're seeing now for several decades,' he added.

Arctic ice is considered vital for the planet as it reflects heat from the sun back into space, helping keep down the planet's temperatures.

The Arctic region is now losing about 155,000 square kilometers (60,000 square miles) of ice annually, the equivalent of a US state every two years, said Walt Meier, a scientist at the National Snow and Ice Data Center.

'It used to be the Arctic ice cover was a kind of big block of ice. It would melt a little bit from the edges but it was pretty solid,' Meier told reporters on a conference call.

'Now it's like crushed ice,' he said. 'At least parts of the Arctic have become like a giant slushie, and that's a lot easier to melt and melt more quickly.'

The planet has charted a slew of record temperatures in recent years, with 13 of the warmest years ever taking place in the past decade and a half, along with extreme weather ranging from severe wildfires in North America to major flooding in Asia.

Researchers have also reported a dramatic melt this summer on the ice sheet in Greenland, which could have major consequences for the planet by raising sea levels.

Scientists believe that climate change is caused by human emissions of carbon and other greenhouse gas emissions.

But efforts to regulate emissions have faced strong political resistance in several nations including the United States, where industry groups have said that regulations would be too costly for the economy.

Kumi Naidoo, the executive director of Greenpeace who on Monday intercepted a Russian ship in the Arctic, said the ice melt showed that the planet was 'warming up at a rate that puts billions of people's future in jeopardy.'

'These figures are not the result of some freak of nature but the effects of man-made global warming caused by our reliance on dirty fossil fuels,' he said in a statement.

Shaye Wolf of the Center for Biological Diversity pressure group called the record ice melt 'a profound -- and profoundly depressing -- moment in the history of our planet.'

The melt has rapidly changed the politics and economics of the Arctic region, with shipping companies increasingly eager to save time by sailing through the once-forbidding waters.

Data released Monday by the Washington-based Center for Global Development found that nations including China, India and the United States were reducing the intensity of their carbon emissions but that the effort was overwhelmed by the surge in power consumption in developing nations.

Perry Renews Call for EPA Waiver in Midst of Drought

Citing severe drought that has damaged more than 55 percent of the country's pastureland, Texas Gov. Rick Perry on Friday once again requested a waiver or partial waiver of the EPA's renewable fuel standard mandate for 2012 and 2013. His letter to the EPA was both echoed and supported by the Texas and Southwestern Cattle Raisers Association . Here are the details.



* According to the EPA , the Renewable Fuel Standard program was created in 2005 as part of the Energy Policy Act of 2005 and expanded by the Energy Independence and Security Act of 2007. The program called for 7.5 billion gallons of renewable fuel to be blended into gasoline by 2012 and 36 billion gallons by 2022.



* The Renewable Fuel Standard was intended to achieve reductions in greenhouse gas emissions, reduce the need for imported petroleum and expand the nation's renewable fuels sector, the EPA stated.



* In his Aug. 24 letter to EPA administrator Lisa Jackson, Perry wrote that implementation of the Renewable Fuel Standards have "done much more harm than good" by driving up grocery prices and putting a strain on businesses.



* With more than 40 percent of the U.S. annual corn supply now being diverted from livestock to fuel in order to meet the Renewable Fuel Standard's corn-based ethanol requirement, in addition to a reduced corn production in 2012 due to the drought, the standard "threatens the sustainability of our agriculture producers," Perry wrote.



* According to a press release from Perry's office, livestock producers in Texas rely heavily on corn-based products for feed. Texas is the number one beef producer in the nation, with more than 6 million head of cattle fed and marketed in Texas each year.



* Perry had also requested a partial waiver in 2008, based on the adverse economic impact of high food costs and harm to the livestock industry. The EPA denied that request.



* Texas and Southwestern Cattle Raisers Association president Joe Parker stated on Friday that "it has been clear from the beginning that putting our food and fuel in competition with one another is bad for the cattle industry and ultimately bad for consumers. This problem is magnified during times of extreme drought like the one we are in now."



* Parker further stated that the government shouldn't be subsidizing or mandating ethanol production when "there's not enough corn to go around."



* On Aug. 20, the EPA requested comment on letters from the Governors of the States of Arkansas and North Carolina, who also asked for waivers of the Renewable Fuel Standard requirements.

UN green climate fund, aiding poor, to pick HQ in 2012

OSLO (Reuters) - Leaders of a fledgling U.N. green fund agreed at a first meeting on Saturday to pick a headquarters this year as part of a plan to oversee billions of dollars in aid to help developing nations fight global warming.

The three-day meeting in Geneva heard pitches from the six countries -- Germany, Mexico, Namibia, Poland, South Korea and Switzerland -- that want to host the Green Climate Fund, the main U.N. body due to manage $100 billion in aid from 2020.

'This first meeting was a very productive start,' Ewen McDonald of Australia, a co-chair of the Fund, said in a statement at the end of the talks among the 24 board members working on details of how the fund will operate.

The board aims to select the host country at a next meeting, set for October 18-20 in South Korea. The choice would then have to be endorsed by environment ministers at U.N. climate talks in Doha in late November and early December.

'It is early days,' Kjetil Lund, deputy Norwegian finance minister and a board member, told Reuters. 'We have to get the right set-up first.'

Developed nations agreed in 2009 to raise climate aid, now about $10 billion a year, to an annual $100 billion from 2020 to help developing countries curb greenhouse gas emissions and cope with floods, droughts, heatwaves and rising sea levels.

The long-term goal of the fund is to 'transform the livelihoods of people responding to the impacts of climate change,' Zaheer Fakir of South Africa, the other co-chair, said in a statement.

There was no discussion yet of the far more controversial issue of how to raise $100 billion from public and private sources. The fund is now empty and the economies of many developed nations are struggling.

The target of $100 billion 'is on the radar screen, in the backdrop,' Henning Wuester, head of the interim secretariat of the fund, told Reuters.

The board's first meeting was delayed by five months because Asian and Latin American nations took longer than expected to agree on their board members.

Focused only on practical details, the Geneva talks avoided stirring up deep mistrust between rich and poor nations about sharing out the burden of fighting global warming that has been a constant stumbling block at U.N. climate negotiations.

'The atmosphere was cordial,' said Karen Orenstein of Friends of the Earth USA. But she complained that civil society observers were not allowed into the board room and limited to watching a webcast from a room nearby.

Green Climate Fund to hold next meeting in South Korea

The Green Climate Fund, which will help poor countries fight global warming, will hold its next meeting from October 18 to 20 in South Korea, the body said Saturday.

The fund was launched at a UN climate conference in Durban, South Africa, last year to help channel up to $100 billion (80 billion euros) a year in aid to poor, vulnerable countries by 2020 via investments from both public and private sources.

Its 24-member board wrapped up a first meeting in Geneva on Saturday after three days of discussions to lay the foundations of the fund, selecting Songdo in South Korea as the location of its next gathering, a statement said.

The board also decided on its process for selecting the country that will host the fund's headquarters, the interim secretariat said, without detailing the strategy.

Of the six nations competing to host the fund -- Germany, Mexico, Namibia, Poland, South Korea and Switzerland -- one will be formally designated in late November at the United Nations Framework Convention on Climate Change (UNFCCC) conference in Doha, Qatar.

The Swiss press reported that Geneva and Bonn, which currently hosts the interim secretariat, are tipped as favourites.

Local irrigation systems provide better food security: study

Farmer-led irrigation schemes provide better food security, protect millions of farmers from climate risks and reduce poverty in sub-Saharan Africa and South Asia, a new study showed Friday.

The findings are of particular interest as food prices escalate due to a weak monsoon season in Asia and a brutal drought in the midwestern and central US, where the world's largest corn and soybean crops are grown.

When farmers manage their small-scale irrigation systems themselves their yields can increase by up to 300 percent in some cases and add tens of billions of dollars to household revenues, the Sri Lanka-based International Water Management Institute (IWMI) found in its study.

The researchers cited the example of a small region in the Indian state of Madhya Pradesh where reservoirs were built to store water from the monsoons.

The water can be stored for up to seven months and makes it possible to increase the amount of arable land during the dry season from 23 to 95 percent.

'It impacts on the farmer's income and the whole community. It was very impact-full for me to see that change,' study coordinator Meredith Giordano told AFP.

Of sub-Saharan Africa's renewable water resources, only three percent are used for agriculture, according to the UN Food and Agriculture Organization (FAO).

Only about four percent of arable land is equipped for irrigation, of which less than six percent is serviced by groundwater.

'We have been focusing on large scale solutions but there is a large range of options out there,' Giordano said.

'Small-scale water technologies are very efficient and a lot of farmers, in groups or individually, adopted them and they are transforming their lives,' she added.

'It's not one or the other. We need investments along the range,' she said.

Between 2009 and 2012, the AgWater project, on which the report is based, studied small-scale irrigation systems among more than 1,000 farmers in South Asia and sub-Saharan Africa, as well as the aid and structural mechanisms.

The study makes recommendations to politicians, organisations and investors to help develop innovative solutions.

The researchers studied numerous options, including pumps, basins, reservoirs, groundwater drainage and various resources used by farmers to improve the situation, Giordano said.

However, there are risks to unchecked expansion of small-scale water management, and access to materials can be difficult which puts the poorest farmers -- often women -- at a disadvantage.

'And if farmers engage in a water free-for-all, supplies in some areas could dwindle past sustainable levels,' the study said.

Innovative business models are also being considered, such as 'pump-on-a-bike' schemes in which entrepreneurs cycle rural areas renting out pumps strapped to their bikes.

The IWMI study was released two days before the opening of the annual World Water Week conference in Stockholm, which focuses each year on a specific water related theme. This year's theme is Water and Food Security.

Climate vs. weather: Extreme events narrow doubts

Heatwaves, drought and floods that have struck the northern hemisphere for the third summer running are narrowing doubts that man-made warming is disrupting Earth's climate system, say some scientists.

Climate experts as a group are reluctant to ascribe a single extreme event or season to global warming.

Weather, they argue, has to be assessed over far longer periods to confirm a shift in the climate and whether natural factors or fossil-fuel emissions are the cause.

But for some, such caution is easing.

A lengthening string of brutal weather events is going hand in hand with record-breaking rises in temperatures and greenhouse-gas levels, an association so stark that it can no longer be dismissed as statistical coincidence, they say.

'We prefer to look at average annual temperatures on a global scale, rather than extreme temperatures,' said Jean Jouzel, vice chairman of the UN's Nobel-winning scientists, the Intergovernmental Panel on Climate Change (IPCC).

Even so, according to computer models, 'over the medium and long term, one of the clearest signs of climate change is a rise in the frequency of heatwaves', he said.

'Over the last 50 years, we have seen that as warming progresses, heatwaves are becoming more and more frequent,' Jouzel said.

'If we don't do anything, the risk of a heatwave occurring will be 10 times higher by 2100 compared with the start of the century.'

The past three months have seen some extraordinary weather in the United States, Europe and east and southeast Asia.

The worst drought in more than 50 years hit the US Midwest breadbasket while forest fires stoked by fierce heat and dry undergrowth erupted in California, France, Greece, Italy, Croatia and Spain.

Heavy rains flooded Manila and Beijing and China's eastern coast was hit by an unprecedented three typhoons in a week.

Last month was the warmest ever recorded for land in the northern hemisphere and a record high for the contiguous United States, according to the US National Oceanic and Atmospheric Administration (NOAA).

Globally, the temperature in July was the fourth highest since records began in 1880, it said.

James Hansen, arguably the world's most famous climate scientist (and a bogeyman to climate skeptics), contends the link between extreme heat events and global warming is now all but irrefutable.

The evidence, he says, comes not from computer simulations but from weather observations themselves.

In a study published this month in the peer-reviewed US journal Proceedings of the National Academy of Sciences (PNAS), Hansen and colleagues compared temperatures over the past three decades to a baseline of 1951-80, a period of relative stability.

Over the last 30 years, there was 0.5-0.6 C (0.9-1.0 F) of warming, a rise that seems small but 'is already having important effects', said Hansen, director of NASA's Goddard Institute for Space Studies.

During the baseline period, cold summers occurred about a third of the time, but this fell to about 10 percent in the 30-year period that followed.

Hot summers which during the baseline period occurred 33 percent of the time, rose to about 75 percent in the three decades that followed.

Even more remarkable, though, was the geographical expansion of heatwaves.

During the baseline period, an unusually hot summer would yield a heatwave that would cover just a few tenths of one percent of the world's land area.

Today, though, an above-the-norm summer causes heatwaves that in total affect about 10 percent of the land surface.

'The extreme summer climate anomalies in Texas in 2011, in Moscow in 2010 and in France in 2003 almost certainly would not have occurred in the absence of global warming with its resulting shift of the anomaly situation,' says the paper.

In March, an IPCC special report said there was mounting evidence of a shift in patterns of extreme events in some regions, including more intense and longer droughts and rainfall. But it saw no increases in the frequency, length or severity of tropical storms.

US FCC green lights Verizon Wireless' cable spectrum deal

WASHINGTON (Reuters) - The U.S. Federal Communications Commission on Thursday approved Verizon Wireless' proposal to purchase $3.9 billion of airwaves from big cable providers.

The agency concluded its review after the Department of Justice cleared the way last week for the deal to move forward with constraints on the companies' marketing agreements.

Verizon Wireless, a joint venture of Verizon Communications and Vodafone Group Plc , last December proposed to buy wireless airwaves from cable companies including Comcast Corp and Time Warner Cable Inc .

UN green climate fund, meant to aid poor, holds first talks

GENEVA (Reuters) - Leaders of a U.N. green fund meant to channel billions of dollars to help developing economies cope with climate change met for the first time on Thursday after months of delays.

The 24-strong board began 3-day talks in Geneva, trying to decide where the fund will be based and other details, officials said. Ways to extract planned new aid from the anaemic economies of rich countries will be left for later meetings.

Developed nations agreed in 2009 to raise climate aid, now about $10 billion a year, to an annual $100 billion from 2020 to help developing countries curb greenhouse gas emissions and cope with floods, droughts, heatwaves and rising sea levels.

Once up and running, the Green Climate Fund is meant to manage rising aid flows. Candidates to host the fund's headquarters are Germany, Mexico, Namibia, Poland, South Korea and Switzerland.

'The Green Climate Fund can be an important tool in the world's common work to prevent climate change,' Norwegian Deputy Finance Minister Kjetil Lund, a member of the board, said in a statement on Thursday.

He said developing nations needed aid to spur greener growth that also enables them to cut greenhouse gas emissions, mainly from burning fossil fuels. The fund is part of a wider effort to work out a United Nations deal to combat climate change.

The board's first meeting was delayed by five months because Asian and Latin American nations took longer than expected to agree on their board members.

'The most important thing is selecting the host country,' Omar El-Arini, a member of the board from Egypt, said of the Geneva talks. He said that the board was due to report back on the sitting to a U.N. meeting in Doha in late November.

'I don't think there will be any serious discussion of the $100 billion,' he added in a phone briefing earlier this week.

Brandon Wu, of anti-poverty campaigners ActionAid USA, noted that U.S. farmers were struggling with drought. But the effects of similar weather 'are even more severe in developing countries where there is no crop insurance, no safety nets,' he said.

'People living in poverty will suffer most,' he said.

The board started its work by electing two co-chairs, Zaheer Fakir of South Africa and Ewen McDonald of Australia, the fund said in a statement.

Curiosity rover takes first short spin around Mars

PASADENA, Calif. (AP) - Curiosity took its first test drive around the gravel-strewn Martian terrain Wednesday, preparation for the ultimate road trip to find out if the red planet's environment could have supported life.

The six-wheel NASA rover did not stray far from the spot where it landed more than two weeks ago. It rolled forward about 15 feet, rotated to a right angle and reversed a short distance, leaving track marks on the ancient soil.

Mission managers were ecstatic that the maiden voyage of the $2.5 billion mission was glitch-free.

'It couldn't be more important,' said project manager Peter Theisinger at the NASA Jet Propulsion Laboratory. 'We built a rover. So unless the rover roves, we really haven't accomplished anything ... It's a big moment.'

The short spin came a day after Curiosity successfully wiggled its wheels to test its steering capabilities.

Curiosity landed in Gale Crater near the Martian equator Aug. 5 to explore whether the environment once supported microbial life. The touchdown site has been named Bradbury Landing in honor of the late 'The Martian Chronicles' author Ray Bradbury, who would have turned 92 on Wednesday.

The rover's ultimate destination is Mount Sharp, a towering mountain that looms from the ancient crater floor. Signs of past water have been spotted at the base, which provides a starting point to hunt for the chemical building blocks of life.

Before Curiosity treks toward the mountain, it will take a detour to an intriguing spot 1,300 feet away where it will drill into bedrock. With the test drive out of the way, Curiosity was expected to stay at its new position for several days before making its first big drive - a trip that will take as long as a month and a half.

Curiosity won't head to Mount Sharp until the end of the year.

Rover driver Matt Heverly said the first drive took about 16 minutes with most of the time used to take pictures. Heverly said the wheels did not sink much into the ground, which appeared firm.

'We should have smooth sailing ahead of us,' he said.

After an action-packed landing that delicately lowered it to the surface with nylon cables, Curiosity has entered a slow streak. Since the car-size rover is the most sophisticated spacecraft sent to Mars, engineers have taken their time to make sure the rover is in tiptop shape and that its high-tech tools work before it delves into its mission.

Curiosity joins the rover Opportunity, which has been exploring craters in Mars' southern hemisphere since 2004. Opportunity's twin, Spirit, fell silent in 2010 after getting stuck in a sand trap.

Earlier this week, Curiosity exercised its robotic arm for the first time, flexing its joints and motors before engineers stowed it again. Weeks of additional tests were planned before it can drill and scoop up Martian soil.

The nuclear-powered rover has been tracking levels of dangerous radiation on the Martian surface in an effort to guide future astronaut landings. It also powered up its weather station, taking hourly readings of air and ground temperatures, pressure and wind conditions.

Over the weekend, it fired its laser at a humble rock to study what it's made of. Unsurprisingly, the zapped rock was typical of other Martian rocks, made of basalt.

During the checkups, scientists discovered a damaged wind sensor, possibly after it was hit by rocks that landed on the rover's instrument deck during landing. Deputy project scientist Ashwin Vasavada said the broken sensor will not jeopardize the mission since there's a spare.

Since nailing the daredevil landing, the rover team has been acknowledged by President Barack Obama. Gov. Jerry Brown, who declared Wednesday as 'Space Day' visited the lab and donned 3-D glasses to view an animation of Curiosity's first drive on a big screen in the control room.

Oil Companies May Have Been Helping Combat Climate Change (A Little)

Here's some good news about climate change: emissions of greenhouse gases other than carbon dioxide have slowed and, in some cases, begun to decline. That means fewer molecules drifting in the atmosphere and blocking the escape of heat radiated by an Earth warmed by sunlight. The bad news is no one knows why.

Now a new study suggests that declines in ethane a simple hydrocarbon molecule and component of the fossil fuel known as natural gas can be attributed to companies stopping the practice of simply releasing the gas that comes up with every barrel of oil. Atmospheric measurements stretching from 1984 to 2010 suggest that ethane emission rates have fallen by a full 21 percent. The study is published in Nature on August 23. (Scientific American is part of Nature Publishing Group).

That's important in its own right but also because of what it suggests about the second most abundant greenhouse gas methane, another simple hydrocarbon and the most abundant molecule in natural gas. Over the span of a century, a methane molecule traps 25 times the amount of heat compared to the most abundant greenhouse gas carbon dioxide.

So how much methane human activities put into the atmosphere has a big impact on how much global warming we end up creating this century (and beyond) and represents a shortcut to restraining climate change, buying time to decrease CO2 emissions.

The 60 to 80 two-liter canisters bearing air samples collected from all around the Pacific Ocean since 1984 suggest that the ethane decline is a result of a decline in so-called fugitive emissions from fossil fuel production. As the name implies, fugitive emissions are molecules of natural gas that got away (usually on purpose). Given the value of natural gas as a fuel, however, the practice of releasing natural gas molecules has declined since the 1970s. As a result, oil companies while funding efforts to question the reality of climate change may have been inadvertently helping keep global warming from getting even worse.

There are other sources of ethane as well, such as wild (and human-set) fires or the burning of biofuels. But ethane emissions from those sources have actually increased, meaning the overall decline has to be attributed to some other source. The remaining possibility ending the practice of simply releasing ethane when producing oil is the most likely explanation, the new research argues.

Methane and ethane emissions have been strongly correlated over the period of the study, suggesting that what happens to ethane will happen to methane. In fact, the delay in a more significant drop in methane may be a result of that molecule's longer lifetime in the atmosphere methane lasts roughly a decade whereas ethane breaks down within a few months.

As mentioned, that's good news. It may also give scientists a way to identify particularly catastrophic climate change scenarios before they set in, like a release of the trillions of molecules of methane trapped in Arctic permafrost or ice cages on the seafloor. If methane levels suddenly rose without a corresponding rise in ethane that might signal that such a geologic burp was happening.

Unfortunately, the rate of the ethane (and possibly methane) decline has slowed over the last decade, according to the record. And it may slow yet further if fugitive emissions from natural gas wells like those currently being fracked in the U.S. or pipelines grow. There's also an opportunity to stop the escape of methane from coal mines in China, oil wells in Africa and the Middle East, and pipelines in Russia if we want to slow global warming. To combat climate change, the decline in atmospheric levels of ethane cannot prove temporary.

S.Africa faults trophy hunting firms amid poaching crisis

Many South African trophy hunting firms fail to meet industry regulations in a country hard-hit by poaching, the environment ministry said on Wednesday after a series of raids.

Investigators found that tannery and taxidermy industries failed to comply with the Threatened Or Protected Species Regulations (TOPS) regulations and national standards regarding the marking of trophies from rhinos and their horns, as well as other game.

Authorities said the blitz was meant to enforce stricter control over the movement of rhino horns in the wake of increased poaching, with 339 rhinos killed since the beginning of the year.

'From a biodiversity perspective, the most frequent issues of non-compliance related to the absence of hunting registers and the absence of TOPS permits,' the department said in a statement.

According to environmental regulations, tannery operators were expected to obtain licences to transport rhino horns from trophy hunts to taxidermists for processing and export.

In return, the taxidermies were required to keep a register detailing the receipt of rhino horns, their weight and the numbers of micro-chips inserted inside the horns.

Poor waste management processes and pollution were also cited.

South Africa allows a limited number of trophy hunts every year, but some traffickers have exploited the hunts to export horns to Asia, where they are then used in the lucrative traditional medicine market.

ON Semi to cut 250 jobs, cancel senior executives' bonuses

(Reuters) - Power-management chipmaker ON Semiconductor Corp said it will cut about 250 jobs and cancel annual cash bonuses for senior executives, including its CEO and CFO, to reduce costs in a weak economic environment.

ON Semiconductor, which earlier this month reported second-quarter revenue below analysts' expectations on lower orders, is struggling with poor performance at its Sanyo segment.

'The one specific segment that ON is trying to fix is the Sanyo acquisition. It is a business that has been losing money since the acquisition,' Robert W Baird & Co analyst Tristan Gerra told Reuters.

The company acquired Sanyo Semiconductor Co Ltd in January 2011 for about $500 million including debt. The division designs, manufactures and sells radio frequency and power-related components used in flash memory devices and touch sensors.

ON had cut 10 percent jobs in the Sanyo division in the second quarter.

Sanyo's business was not growing at the time of the acquisition and it was further impacted negatively by the Japanese earthquake and the Thai floods, Gerra said.

Japanese companies, which are Sanyo's biggest customers, have also not been doing well, he added.

Sony Corp and Canon Inc have cut their full-year operating profit forecast on a strong yen and a weak global economy.

Panasonic Corp, another major customer, slashed workforce by 36,000 last year and is expected to continue cutting jobs.

ON expects to complete most of the job cuts in the current quarter and take a related charge of $11 million to $14 million, it said in a regulatory filing on Wednesday.

The company had a global workforce of 19,442 last year, according to its annual report.

A weak spending environment has pushed several chipmakers into a rough patch, with ON's rivals such as Fairchild Semiconductor International Inc and Cypress Semiconductor Corp forecasting weak growth.

ON Semiconductor shares, which have fallen 14 percent since the beginning of the year, were trading flat at $6.59 on the Nasdaq.

ON Semiconductor to cut 250 jobs

(Reuters) - Power-management chipmaker ON Semiconductor Corp said it will cut about 250 jobs and cancel its annual cash incentive program for senior executives to reduce costs in a weak macroeconomic environment.

The company expects to complete most of the job cuts in the current quarter and estimated a related charge of $11 million to $14 million, it said in a filing on Wednesday.

ON Semiconductor had a global workforce of 19,442 last year, of which 2,411 employees were in the U.S., according to the company's annual report.

Rival Intersil Corp said in May that it would reduce its workforce by 11 percent to cut costs and revamp its product portfolio.

A weak spending environment has forced chipmakers into a rough patch, with many including Fairchild Semiconductor International Inc and Cypress Semiconductor Corp forecasting weak growth on falling orders and lower consumer spending.

ON Semiconductor, which makes radio-frequency custom chips for consumer, automotive and industrial markets cut 10 percent jobs in one of its core segments in the last quarter.

It counts Flextronics Corp, Samsung Electronics Co Ltd, Sony Corp and Panasonic Corp among its customers.

The company had earlier this month reported second-quarter revenue below expectations as orders fell. It also said its Chief Financial Officer Donald Colvin had resigned.

The chipmaker has been streamlining its operations since last year, when it said it would close its wafer manufacturing facility in Aizu, Japan.

The company, whose revenue has declined over the last four quarters, said the cost-cutting measures are being undertaken to bring its spending in line with revenue projections.

ON Semiconductor, whose shares have fallen 14 percent since the beginning of the year, forecast third-quarter revenue of between $725 million and $765 million.

The Phoenix, Arizona-based company's shares closed at $6.63 on the Nasdaq on Tuesday.

U.S. testing "talking" cars to avoid crashes, congestion

ANN ARBOR, Michigan (Reuters) - Michael Knight in the television series 'Knight Rider' had one. Pixar made a movie about them. Now the U.S. government is testing a fleet of so-called 'talking' cars that may help American drivers avoid crashes and traffic jams.

Over the next year, U.S. officials and the University of Michigan will fit nearly 3,000 cars, trucks and buses with wireless devices that track other vehicles' speed and location, alert drivers to congestion or change a traffic light to green.

Granted, these cars will not be as chatty as actor David Hasselhoff's talking car KITT in the popular 1980s series 'Knight Rider,' or the cast of Pixar's animated movie 'Cars.' But they will warn about potential crashes through loud beeps, flashes or vibrations in the driver's seat.

In fact, 'vehicle-to-vehicle' communication might help avoid or reduce the severity of four out of five crashes that occur when the driver is not impaired, U.S. safety regulators said.

'This is a big deal and I think everybody here believes this has a lot of promise,' Transportation Secretary Ray LaHood told reporters on Tuesday at an Ann Arbor, Michigan, event.

'But until we see the data, until the study is complete, we won't know with certainty what promise it really has. A year from now I think we will.'

The results of the experiment will help the National Highway Traffic Safety Administration decide if the technology should be mandatory. A decision on such a rule would not be made until the test ends in August 2013, LaHood added.

The road test underway now is the largest of its kind. The vehicles will be driven in Ann Arbor, a college town of nearly 28 square miles with a population of nearly 115,000.

Eight major automakers, including General Motors Co and Toyota Motor Corp, supplied the cars. The test will cost $25 million, with 80 percent of the money coming from the Transportation Department.

'SEEING EVERYBODY'

The vehicles will also be able to communicate with roadside devices in 29 areas in Ann Arbor. If conditions are safe, the vehicles can change the traffic light to green or let the driver know if a light is about to change.

Connected vehicle systems use a technology similar to Wifi called dedicated short range communication, which is unlikely to be vulnerable to interference, U.S. officials said.

The cars can track other cars' location and speed. They can also determine if a driver is braking or turning the wheel. Details such as the license number or VIN number are not shared.

Automakers currently use radars or cameras to spot problems. Ford Motor Co's cross-traffic alert system uses two rear radars to detect passing vehicles within 45 feet when a driver pulls out of a parking spot.

Radar systems that alert drivers to a possible head-on collision have a reach of up to 200 meters, said John Scally, manager of electric safety and driver assist systems for Honda Motor Co Ltd's U.S. development arm.

The wireless system, however, can detect cars up to 300 meters away. This system can also alert drivers if a nearby but unseen car brakes suddenly. Radar systems cannot detect vehicles around a corner and out of view.

'We've done things with cameras and radars to look for vehicles around you and on the side. But those are just using proximity sensors,' Scally said. 'This will allow us to see everybody around us,' he said of the wireless system.

BEEPS AND BUZZING

The road test represents the second phase of the Department of Transportation's connected vehicle safety program. In a study conducted in 2011 and early 2012, the department found that nine out of 10 drivers had a 'highly favorable' opinion of vehicle-to-vehicle technology.

Each automaker has found a different way of alerting drivers to potential crashes. Many automakers use loud beeps or sounds or a certain message on the digital instrument cluster. Others use more discreet haptic systems, which vibrate the driver's seat or steering wheel.

Some use all three. Ford uses beeps, red LED lights and a vibrating seat to tell the driver to slow down, said Ford's technical leader for vehicle communications Michael Shulman.

Executives said it is crucial that vehicles' safety alerts are not overly sensitive. Too many warnings would likely annoy drivers who might turn them off or ignore them outright.

'We want people to get warnings when they need warnings,' Shulman said. 'But we don't want them to get alerts when there's a car in another lane that's not really a threat.'
