A new greenhouse gas that is 7,000 times more powerful than carbon dioxide at warming the Earth has been discovered by researchers in Toronto.
The newly discovered gas, perfluorotributylamine (PFTBA), has been in use by the electrical industry since the mid-20th century.
The chemical, that does not occur naturally, breaks all records for potential impacts on the climate, said the researchers at the University of Toronto's department of chemistry.
"We claim that PFTBA has the highest radiative efficiency of any molecule detected in the atmosphere to date," said Angela Hong, one of the co-authors.
The study, published in the journal Geophysical Research Letters, found PFTBA was 7,100 times more powerful at warming the Earth over a 100-year time span than CO2.

If you can't afford to own, you can rent. But what if you can't afford to rent, either? Millions of Americans are in precisely that situation, according to a study released today by the Joint Center for Housing Studies of Harvard University. The availability of apartments, especially cheaper ones, hasn't nearly kept up with demand, and the problem has worsened since the 2007-09 recession, the study says.

Threat of 'dead zone' developing off Sonoma Coast... unprecedented mass of oxygen-poor water off the Sonoma Coast, a phenomenon that could harm the region's prized Dungeness crab and other marine life.
Scientists at the Bodega Marine Laboratory, who were the first to detect the hypoxic (low-oxygen) waters, aren't calling it a "dead zone" yet, despite the similarity to a lethal condition along the Oregon coast for the past 12 years and forecasts that it will occur worldwide with global warming.
"There's nothing dead," said John Largier, an oceanographer at the UC Davis research facility on Bodega Head. But equipment on a bright yellow buoy anchored about a mile offshore has recorded dissolved oxygen levels low enough to cause "significant distress" for some marine organisms, he said.
Oxygen-poor water is common in deep water of the open ocean, but until this year had never been documented over the continental shelf close to the Sonoma coast, he said.
The flow of terrestrial groundwater to the sea is an important natural component of the hydrological cycle. This process, however, does not explain the large volumes of low-salinity groundwater that are found below continental shelves. There is mounting evidence for the global occurrence of offshore fresh and brackish groundwater reserves. The potential use of these non-renewable reserves as a freshwater resource provides a clear incentive for future research. But the scope for continental shelf hydrogeology is broader and we envisage that it can contribute to the advancement of other scientific disciplines, in particular sedimentology and marine geochemistry.
Vast freshwater reserves have been discovered under the ocean floor which scientists believe could sustain future generations.
Australian researchers claim to have found 500,000 cubic kilometres (500 trillion tons) of freshwater buried beneath the seabed on continental shelves off Australia, China, North America and South Africa. The water could be accessed using the technology of deepwater oil drilling rigs. The infrastructure of pipelines could be setup to access millions of tons per day.
The discovery comes as United Nations estimates suggest water use has been growing at more than twice the rate of the population of the world over the last century.

A study released by the CDC's Agency for Toxic Substance & Disease Registry on Thursday confirmed a long-suspected link between chemical contaminants in tap water at the Marine Corps base and serious birth defects such as spina bifida
It also showed a slightly elevated risk of childhood cancers including leukemia.
Dr. Vikas Kapil, a medical officer and acting deputy director of the CDC agency that produced the study, said it surveyed the parents of 12,598 children born at Lejeune between 1968 and 1985, the year most contaminated drinking water wells at Camp Lejeune were closed.

Shanghai authorities ordered schoolchildren indoors and halted all construction on Friday as China's financial hub suffered one its worst bouts of air pollution, bringing visibility down to a few dozen meters and obscuring the city's spectacular skyline.
The financial district was shrouded in a yellow haze and noticeably fewer people walked the city's streets. Vehicle traffic was thinner, as authorities pulled 30% of government vehicles from the roads. They also banned fireworks and stopped all public sporting events.
Protective masks and air purifiers were selling briskly at local stores.
"I feel like I'm living in clouds of smog," said Zheng Qiaoyun, a local resident who kept her 6-month-old son at home. "I have a headache, I'm coughing, and it's hard to breathe on my way to my office."

..."Practical thermionic generators have reached efficiencies of about 10 percent. The theoretical predictions for our thermoelectronic generators reach about 40 percent, although this is theory only," noted Mannhart. "We would be much surprised if there was a commercial application in the marketplace within the next five years, but if companies that are hungry for power recognize the potential of the generators, the development might be faster."

"China and India hold the world's fate in their hands as energy use skyrockets in poorer countries. "
The Energy Shift now under way is as much geographical as it is technological. Case in point: By 2040, the developing world will account for 65 percent of the world's energy consumption, according to a report released today by the United States Energy Information Administration.
That's up from 54 percent in 2010, and over the next three decades energy consumption is predicted to grow at a 2.2 percent annual clip in non-OCED (Organization for Economic Cooperation and Development) countries. OCED nations – including Europe, the US, Canada and Australia – in contrast, will see their energy use increase by just 0.5 percent a year, roughly in line with population growth.

Coal companies look to cash in by capturing leaking methane from mines and selling carbon credits to California
And there's plenty of methane waiting to be sold. "The air coming out of the Enlow mine is about 0.8 percent methane, but there's 181,000 cubic feet of it being ventilated each minute," Litvak writes. At Consol's McElroy mine in Marshall County, West Virginia (Wikipedia map), "the air is 1.2 percent methane, and 209,000 cubic feet of it is released each minute. Destroying that methane offsets the emissions of a 50 megawatt coal plant each year."
The only hurdle is that critics "have argued that awarding credits to coal-mine methane would deflect resources from greener technologies with a more local impact," a fear that stalled a decision by the Air Resources Board in October, Litvak writes. But if the board approves a protocol, it will mean big money for coal companies, because of the higher cost of selling into the California carbon market. "For a project the size of Enlow or McElroy, the difference between selling on the voluntary market and selling into the California carbon market is the difference between $300,000 and $3 million a year."

"The grid was not built for renewables," said Trieu Mai, senior analyst at the National Renewable Energy Laboratory.
The frailty imperils lofty goals for greenhouse gas reductions. Concerned state and federal officials are spending billions of dollars in ratepayer and taxpayer money in an effort to hasten the technological breakthroughs needed for the grid to keep up with the demands of clean energy.
Making a green energy future work will be "one of the greatest technological challenges industrialized societies have undertaken," a group of scholars at Caltech said in a recent report. The report notes that by 2030, about $1 trillion is expected to be spent nationwide in bringing the grid up to date.
The role of the grid is to keep the supply of power steady and predictable. Engineers carefully calibrate how much juice to feed into the system as everything from porch lights to factory machines are switched on and off. The balancing requires painstaking precision. A momentary overload can crash the system.
California has taken some of the earliest steps to address the problems. The California Public Utilities Commission last month ordered large power companies to invest heavily in efforts to develop storage technologies that could bottle up wind and solar power, allowing the energy to be distributed more evenly over time.
Whether those technologies will ever be economically viable on a large scale is hotly debated. The commission mandate nonetheless requires companies to produce enough storage by 2024 to power about 1 million homes.
"Energy storage has the potential to be a game changer for our electric grid," Commissioner Mark Ferron said.
