New Study Shows Total North American Methane Leaks Far Worse than EPA Estimates | DeSmogBlog.

Just how bad is natural gas for the climate?
A lot worse than previously thought, new research on methane leaks concludes.
Far more natural gas is leaking into the atmosphere nationwide than the Environmental Protection Agency currently estimates, researchers concluded after reviewing more than 200 different studies of natural gas leaks across North America.
The ground-breaking study, published today in the prestigious journal Science, reports that the Environmental Protection Agency has understated how much methane leaks into the atmosphere nationwide by between 25 and 75 percent — meaning that the fuel is far more dangerous for the climate than the Obama administration asserts.
The study, titled “Methane Leakage from North American Natural Gas Systems,” was conducted by a team of 16 researchers from institutions including Stanford University, the Massachusetts Institute of Technology and the Department of Energy’s National Renewable Energy Laboratory, and is making headlines because it finally and definitively shows that natural gas production and development can make natural gas worse than other fossil fuels for the climate.
The research, which was reported in The Washington Post, Bloomberg and The New York Times, was funded by a foundation created by the late George P. Mitchell, the wildcatter who first successfully drilled shale gas, so it would be hard to dismiss it as the work of environmentalists hell-bent on discrediting the oil and gas industry.
The debate over the natural gas industry’s climate change effects has raged for several years, ever since researchers from Cornell University stunned policy-makers and environmentalists by warning that if enough methane seeps out between the gas well and the burner, relying on natural gas could be even more dangerous for the climate than burning coal.
Natural gas is mostly comprised of methane, an extraordinarily powerful greenhouse gas, which traps heat 86 times more effectively than carbon dioxide during the two decades after it enters the atmosphere, according to the Intergovernmental Panel on Climate Change, so even small leaks can have major climate impacts.
The team of researchers echoed many of the findings of the Cornell researchers and described how the federal government’s official estimate proved far too low.
“Atmospheric tests covering the entire country indicate emissions around 50 percent more than EPA estimates,” said Adam Brandt, the lead author of the new report and an assistant professor of energy resources engineering at Stanford University. “And that’s a moderate estimate.”
The new paper drew some praise from Dr. Robert Howarth, one of the Cornell scientists.
“This study is one of many that confirms that EPA has been underestimating the extent of methane leakage from the natural gas industry, and substantially so,” Dr. Howarth wrote, adding that the estimates for methane leaks in his 2011 paper and the new report are “in excellent agreement.”
In November, research led by Harvard University found that the leaks from the natural gas industry have been especially under-estimated. That study, published inthe Proceedings of the National Academy of Science, reported that methane emissions from fossil fuel extraction and oil refineries in some regions are nearly five times higher than previous estimates, and was one of the 200 included in Thursday’s Science study.
EPA Estimes Far Off-Target
So how did the EPA miss the mark by such a high margin?
The EPA’s estimate depends in large part on calculations — take the amount of methane released by an average cow, and multiply it by the number of cattle nationwide. Make a similar guess for how much methane leaks from an average gas well. But this leaves out a broad variety of sources — leaking abandoned natural gas wells, broken valves and the like.
Their numbers never jibed with findings from the National Oceanic and Atmospheric Administration and the U.S. Department of Energy, which approached the problem by taking measurements of methane and other gas levels from research flights and the tops of telecommunications towers.
But while these types of measurements show how much methane is in the atmosphere, they don’t explain where that methane came from. So it was still difficult to figure out how much of that methane originated from the oil and gas industry.
At times, EPA researchers went to oil and gas drilling sites to take measurements. But they relied on driller’s voluntary participation. For instance, one EPA study requested cooperation from 30 gas companies so they could measure emissions, but only six companies allowed the EPA on site.
“It’s impossible to take direct measurements of emissions from sources without site access,” said Garvin Heath, a senior scientist with the National Renewable Energy Laboratory and a co-author of the new analysis in a press release. “Self-selection bias may be contributing to why inventories suggest emission levels that are systematically lower than what we sense in the atmosphere.” (DeSmog haspreviously reported on the problem of industry-selected well sites in similar research funded by the Environmental Defense Fund.)
Worse than Coal?
There was, however, one important point that the news coverage so far missed and that deserves attention — a crucial point that could undermine entirely the notion that natural gas can serve as a “bridge fuel” to help the nation transition away from other, dirtier fossil fuels.
In their press release, the team of researchers compared the climate effects of different fuels, like diesel and coal, against those of natural gas.
They found that powering trucks or busses with natural gas made things worse.
“Switching from diesel to natural gas, that’s not a good policy from a climate perspective” explained the study’s lead author, Adam R. Brandt, an assistant professor in the Department of Energy Resources at Stanford, calling into question a policy backed by President Obama in his recent State of the Union address.
The researchers also described the effects of switching from coal to natural gas for electricity — concluding that coal is worse for the climate in some cases. “Even though the gas system is almost certainly leakier than previously thought, generating electricity by burning gas rather than coal still reduces the total greenhouse effect over 100 years, the new analysis shows,” the team wrote in a press release.
But they failed to address the climate impacts of natural gas over a shorter period — the decades when the effects of methane are at their most potent.
“What is strange about this paper is how they interpret methane emissions: they only look at electricity, and they only consider the global warming potential of methane at the 100-year time frame,” said Dr. Howarth. Howarth’s 2011 Cornell study reviewed all uses of gas, noting that electricity is only roughly 30% of use in the US, and describing both a 20- and a 100-year time frame.
The choice of time-frame is vital because methane does not last as long in the atmosphere as carbon dioxide, so impact shifts over time. “The new Intergovernmental Panel on Climate Change (IPCC) report from last fall — their first update on the global situation since 2007 — clearly states that looking only at the 100 year time frame is arbitrary, and one should also consider shorter time frames, including a 10-year time frame,” Dr. Howarth pointed out.
Another paper, published in Science in 2012, explains why it’s so important to look at the shorter time frames.
Unless methane is controlled, the planet will warm by 1.5 to 2 degrees Celsius over the next 17 to 35 years, and that’s even if carbon dioxide emissions are controlled. That kind of a temperature rise could potentially shift the climate of our planet into runaway feedback of further global warming.
“[B]y only looking at the 100 year time frame and only looking at electricity production, this new paper is biasing the analysis of greenhouse gas emissions between natural gas and coal in favor of natural gas being low,” said Dr. Howarth, “and by a huge amount, three to four to perhaps five fold.”
Dr. Howarth’s colleague, Prof. Anthony Ingraffea, raised a similar complaint.
“Once again, there is a stubborn use of the 100-year impact of methane on global warming, a factor about 30 times that of CO2,” Dr. Ingraffea told Climate Central, adding that there is no scientific justification to use the 100-year time window.
“That is a policy decision, perhaps based on faulty understanding of the climate change situation in which we find ourselves, perhaps based on wishful thinking,” he said.
For its part, the oil and gas industry seems very aware of the policy implications of this major new research and is already pushing back against any increased oversight of its operations.
“Given that producers are voluntarily reducing methane emissions,” Carlton Carroll, a spokesman for the American Petroleum Institute, told The New York Times in an interview about the new study, “additional regulations are not necessary.”

Uranium mine troubles Native American groups – Features – Al Jazeera English
Uranium mine troubles Native American groups – Features – Al Jazeera English.
The project would be built on a mountain considered sacred by Navajos and Pueblos in New Mexico.Samuel Nelson Gilbert Last updated: 09 Feb 2014 13:14

Mounds of radioactive waste dot the eastern portion of the Navajo Nation in the US state of New Mexico. The earthen monoliths contain contaminated material from the more than 250 abandoned uranium minesthat once provided the raw materials for the US nuclear complex. As the Cold War ended, so did the demand for uranium. Yet growing international investment in nuclear energy has led to the prospect of renewed uranium mining in New Mexico, including the controversial newRoca Honda mine located on Mount Taylor, an area considered sacred by the Navajo and Pueblopeoples of the southwestern United States. “If developed, Roca Honda will be a huge underground mine with tremendous impacts,” said environmental attorney Eric Jantz. “This mine could destroy people’s water, land, their places of worship – all for the purposes of funnelling profits to a Canadian company that is in turn selling it to Korea.” The Roca Honda project, operated by Energy Fuels, is one of four proposed New Mexico uranium mines in the permitting stage, said Jon J Indall, an attorney representing the four mining companies ready to begin operations in the coming years. “The market is a bit sluggish now, but these operations are poised to catch the next upswing.” The prospect of renewed uranium development has triggered a contentious debate in New Mexico, a state still reeling from the radioactive contamination caused by uranium mining and the economic decline that followed the exit of the industry from the country’s third-poorest state. “These four projects have the potential to provide 1,000 jobs and millions of dollars in tax revenue,” Indall told Al Jazeera. “This, all for a state whose economy is not exactly booming.” Navajo opposition But many from the Navajo Nation vehemently oppose the return of an industry that left hundreds of abandoned and un-reclaimed mines, mill sites and waste piles on indigenous lands. These continue to contaminate water, soil, livestock and housing, causing heath problems for an impoverished and historically marginalised native community. Larry King, a former miner and member of the Eastern Navajo Dine Against Uranium Mining (ENDAUM), said: “People still talk about Three Mile Island and Chernobyl. Church Rock, where I am from, had the largest radioactive accident in US history, and 19 abandoned mines that remain today, [are] poisoning our community. But no one talks about this, they talk about new mining instead.”
Beginning in the 1950s, thousands of Native Americans like King found work in New Mexico’s uranium mines. They were often poorly paid, unprotected and uninformed about the dangers of uranium dust inhalation and chronic radiation exposure. Nadine Padilla, the director of the MASE coalition, an organisation formed in 2008 by communities affected by mining, spoke to Al Jazeera about what she said were the health effects caused by the mining. “Every day I see people with kidney disease, respiratory problems, and many women fighting various forms of cancer. People still live in houses made with radioactive material from the mills… Baca, where my family is from, has one of the most polluted groundwater systems in the state.” But others from the region welcome the return of the industry. When asked about his thoughts on new uranium mining projects, Jack Farley, who has worked as a miner for 28 years, exclaimed, “Oh God yes, this economy needs it bad! Things have changed. When I worked there were no laws. I worked 500-1,000 working levels of radiation – that’s 999 times what is allowed now. But I think a lack of education has people still thinking uranium mining is dangerous.” Health and controversy The harmful effects of exposure to radon, a radioactive gas often found in uranium mines, are well-known. Yet an absence of health studies or environmental monitoring have led to a poor understanding of the effects of the uranium legacy on the Navajo Nation. “Part of the reason is that these are marginalised communities, low income, communities of colour, indigenous communities,” said Jantz. “They don’t have the political power or the resources it takes to get the federal government or state government to do the basic science behind the health costs of uranium mining.” The Church Rock Uranium Monitoring Project (CRUMP) began in 2003 to assess the effects of the 1979 tailings dam failure, which released 1,100 tons of radioactive waste into the Puerco River, and other abandoned mines. According to the Environmental Protection Agency, at the infamous Church Rock mine, “residents graze sheep, cattle and horses, and collect herbs around the area. Due to the proximity of the residents to the mine site, this mine was identified as the highest priority for cleanup by US EPA and Navajo Nation EPA of over 500 abandoned uranium mines on the Navajo Nation.” King said, “Even before the ’79 spill, contamination from untreated mine watering would flow through our community. After the dam break, it only continued. Kids used to play in the wash, in the mine waste – there were no fences, no signs. I used to graze our sheep where the mines were.” The CRUMP finding showed contamination of numerous wells and springs in the communities in and around Church Rock, as well as dangerous radon levels in homes made with contaminated materials – equivalent to a lifetime cancer risk of smoking one to two packs of cigarettes a day. A more comprehensive health study, still under way, found that of the 1,300 people surveyed, “those people living closer to waste site were more likely to have hypertension, auto-immune disease, while people who had history of exposure during active mining had an additional likelihood of kidney disease”, as principal investigator Johnnye Lewis told Al Jazeera.
In response to the contamination, the Navajo Nation enacted a moratorium on uranium mining in 2005, as well as a ban on transporting uranium across reservation land. Now, the prospect of new mining projects has created a rift within the country’s largest Native American reservation, as certain chapters and officials have come out in support of new uranium projects. A new bill sponsored by Navajo Council Delegate Leonard Tsotsi has allowed Uranium Resources, Inc to construct a “demonstration project” that would extract uranium ore in the Church Rock chapter. The legislation, seemingly at odds with the uranium ban, has been endorsed by chapter president Johnny Henrie as well as a number of other prominent Navajo officials. Henrie was unavailable for comment for this article. Some, including Navajo activist Leona Morgan, assume foul play. “These are old tactics from the past, divide-and-conquer. Today, companies target families who have rights to lease their land, they target politicians and offer them something. Right now, everyone is wondering what Leonard Tsotsi and these pro-uranium families are getting.” King, who lives just across the road from the proposed mine, agreed with Morgan’s assessment. “These men are supposed to protect the community. But you show them a little green, and that changes.” Increased demand? In the end, the prospect of new uranium mining will likely have less to do with the internal controversy than with global economic factors related to the growth of the nuclear energy industry. According to a January 3 report by the World Nuclear Association, there are 435 operable reactors in the world right now, 71 reactors under construction, 172 planned, and another 312 have been proposed. As Curtis Moore, the director of investor and public relations at Energy Fuels, told Al Jazeera, “There is clearly significant growth in the industry. We’re going to have to get the uranium from somewhere. There is certainly a probability some will come from New Mexico.” The controversy over renewed mining is far from over, but Curtis believes it comes down to economy. “Uranium mining has gotten a bad rap in the past. But the bottom line is that these projects create jobs, they create tax revenues, they provide clean nuclear energy for the world.” But King remains sceptical. “Clean has not been my experience.” |
Critics: EPA’s Negligent Policies Are Causing Honeybees to Die – Susanne Posel | Susanne Posel

Honeybees are dying and it looks like the Environmental Protection Agency (EPA) is responsible because of a system called “conditional registration” that expedites the process of getting pesticides to market.
Experts maintain that this lackadaisical formula has allowed dangerous chemicals to be sold to the public and used in commercial operations that have caused massive deaths of honeybee colonies and placed agriculture as a whole under constant threat.
The US Department of Agriculture (USDA) states : “Insecticides conditionally registered in the early 2000s have been blamed for impairing honeybees’ immune systems; in the past five years, the honeybee population has declined 20 to 30 percent each year.”
The Government Accountability Office (GOA) found that the EPA has confused a “record-keeping system for tracking pesticides” that has contributed to the dangers to our ecosystem and the health of millions of Americans.
Problems with missing data while programs pushed through deadly chemicals to be purchased by the public under the guse of being safe has become normal at the EPA.
Although the EPA claims to have begun taking steps to correct these loopholes, they still assert that as long as the manufacturer of the pesticide follows the rules, there is not “unreasonable risk to the environment” and “the use of pesticide[s] is in the public interest” – not to mention the financial interest of producers of pesticides.
An estimated 16,000 pesticides are currently registered with the EPA.
No centralization of power and a lack of monitoring have resulted in handwritten notes and decisions based on memory being entered into files as legitimate documentation.
Earlier this year, researchers at Emory University and the University of California have studied bumblebees in Colorado and discovered that the most devastated impact is felt in the plants that are dying because of lack of pollination.
At a laboratory in Crested Butte, Colorado, Berry Brosi and Heather Briggs were assisted by numerous assistants who analyzed how species of bumblebees and utilized algorithms to assert that if other surviving species of bumblebees were to “pick up the slack”. Plant life would be able to recover.
It appears that bumblebees discriminated against a specific species of flower; the purple wildflower called Delphinium barbeyi (a type of larkspur).
Species of plant life have been in decline because of the sudden lack of bees worldwide.
In 2011, the UN Environmental Program (UNEP) released a report thatidentified an estimated “dozen factors, ranging from declines in flowering plants and the use of memory-damaging insecticides to the world-wide spread of pests and air pollution, may be behind the emerging decline of bee colonies across many parts of the globe.”
In the report, several key issues were mentioned:
• Viral fungal pathogens were destroying the bee colonies
• Migration of bees globally was observed
• Globalization of trade impacted bees
• Speices of plants are dying
• “Systemic insecticides” were causing toxicity in bees
• Climate change is disturbing flowering times
• Climate change is causing less quality pollen to be produced by flowers
A team of researchers at the Washington State University (WSU) have imported bee sperm from the European honeybee for storage and future fertilization.
Scientists want to fertilize American queen bees with European bee sperm to genetically engineer bees that are more resilient to a mysterious condition that coerces worker bees to abandon their hives to die.
The theory is that with this genetic manipulation, stronger bees can be created that will lead to healthier American insects.
The sperm that is not used in these experiments will be frozen for future use.
