Environmental groups strongly oppose the practice of hydraulic fracturing, or fracking, which involves extracting gas from rocks by breaking them up with water and chemicals at high pressure. But the government, keen to cut Britain’s reliance on imports as North Sea gas supplies dry up, has tightened regulations and has given Cuadrilla permission to frack two wells at its Preston New Road site in Lancashire. Cuadrilla, 47.4 percent owned by Australia’s AJ Lucas and 45.2 percent owned by a fund managed by Riverstone, said it would spend at least three months fracking two horizontal wells to test flow rates to determine whether full-scale gas extraction would be viable. The British Geological Survey estimates shale gas resources in northern England alone could amount to 1,300 trillion cubic feet (tcf) of gas, 10 percent of which could meet the Britain’s demand for almost 40 years. “Shale gas has the potential to be a new domestic energy source, enhancing our energy security and delivering economic benefits, including the creation of well-paid, quality jobs,” the Department for Business, Energy and Industrial Strategy said. “We have been clear that any shale developments must be safe and environmentally sound,” the department added in a statement. Attempts to extract the gas have come under fire from local communities and campaigners concerned about the potential effect on the environment and ground water. They say extracting more fossil fuel is at odds with Britain’s commitment to reduce greenhouse gas emissions. “It is morally bankrupt to be heralding the start of a whole new fossil fuel industry,” Craig Bennett, chief executive of environmental group Friends of the Earth said in a statement. “You can deal with climate change or you can have fracking – you can’t do both,” he said. The government asked its climate advisers on Monday to examine whether Britain should toughen its climate targets and set a date to move to a net zero emissions goal. Britain has an existing target to cut its greenhouse gas emissions by 80 percent compared with 1990 levels by 2050.
Britain's Cuadrilla starts fracking for gas after seven-year pause.

The latest work, which appears in the journal PNAS, Proceedings of the National Academy of Sciences of the United States of America, also suggests that different policy steps might be needed in that case. “My study essentially shows that the methods used and analyses presented in the original research are insufficient to rule out other explanations (for lower IQ),” said Ole Rogeberg, an economist at the Frisch Centre for Economics Research in Oslo, to Reuters. The Dunedin Multi-disciplinary Health and Development Study is an ongoing report produced by New Zealand’s University of Otago, monitoring 1,037 New Zealand children born between April 1972 and March 1973. The study followed them for 40 years. The participants were periodically tested for IQ and other indices including drug taking, and in 2012 clinical psychologist Madeline Meier produced a study saying there was a link between teenage cannabis use and a lower IQ. Researchers in the Meier study compared the IQ trends of people who never smoked cannabis with four groups of those who did: people who smoked, people who scored as dependent in a follow-up survey, those who scored as dependent twice and those who scored as dependent three times. The study found IQ declines increasing “linearly” with cannabis use, Rogeberg wrote in PNAS. The crucial assumption in the Meier study is that cannabis use is the only relevant difference between the groups tested, he said. His use of a simulation model showed that it may be premature to draw a causal inference between marijuana use and falling IQ scores. For one thing, other writing about the Dunedin group on which Meier’s study is based suggest that early cannabis use is more common for people with poor self-control, previous conduct problems, and high scores on risk factors linked to low family socioeconomic status, he wrote. Given these factors, young people from lower status families tended to end up in less intellectually demanding environments, whether by choice or by circumstance, which would increase the difference in IQ levels as they aged. “We know that the researchers have measured the IQ of the participants at various ages in childhood - but we don’t know if the IQ changes were similar for the different cannabis-using groups before their cannabis use,” he told Reuters. “We don’t know how much of the change in IQ we can explain by differences in education, jail time, occupational status, etc and whether this affects the estimates in the paper.”
Study casts doubt on link between cannabis, teen IQ drop.

"Scott Henson of Austin, who writes the Grits for Breakfast blog on criminal justice policy and politics, told the Austin Post, an online community newspaper, that Texas and the nation have ""criminalized far too much of public life."" ""I think we have somewhere in the range of 2,500 or so felonies on the books in Texas,"" Henson said in an interview posted online Feb. 25, 2013. ""There are 11 different felonies you can commit with an oyster."" That cracked our interest, partly because the conservative Texas Public Policy Foundation likewise said about a month earlier that Texas has 11 felonies (not a dozen, dang it) related to harvesting oysters. Felonies are considered the most serious criminal offenses. By email, the center’s Marc Levin, director of its Center for Effective Justice, pointed out a January 2012 publication, the ""Current Offense Severity Rankings List,"" written by the Texas Board of Pardons and Paroles. Henson told us by email that Levin was his source for the count when he initially wrote about the topic in 2007. He also said he would check his claim against the state’s ""offense severity"" list. Among the state-listed 2,324 felonies, Levin said, some are rather similar or are enhancements of lesser offenses, though the agency ""presumably uses a consistent methodology to delineate each separate offense."" He said the tally of oyster-related felonies aired by the foundation ""allows for some that the parole board counts as separate offenses which some might consider to be essentially the same offense."" We spotted 16 oyster-connected felonies on the list but pruned three that appeared to be duplicates. Also, as Levin noted, two felonies appeared distinct from others only because they take into consideration repeat offenses. Theft of oysters from a private bed is a felony, as is theft of oysters from a private bed and having two or more previous convictions. Similarly, harvesting oysters in a restricted area is a felony, as is oystering in a restricted area with a previous conviction. Adjusting for the seeming duplications and near-similar felonies knocked the oyster-tied felonies in state law to 11: theft of oysters placed on a private seabed; interfering with an oyster buoy or marker with two previous convictions; oystering in a restricted area as designated by the state; night dredging of oysters; night dredging in a restricted area with a previous conviction; night dredging in a polluted area; not having an oystering license; harvesting oysters for non-commercial purposes without a license; harvesting oysters without a commercial license; selling sport oysters; and violating oyster regulations. By telephone and email, a Texas Parks and Wildlife Department official confirmed the felonies, though Brandi Reeder, the agency’s fisheries law administrator, stressed that a person could be charged with each felony only if they have been convicted of similar misdemeanor violations in the previous five years--sometimes just once, in other cases two or more times, according to the relevant statutes. At our request, Reeder reviewed our identified 11 felonies, later saying by email that she would say there are seven distinct oyster-related offenses or crimes. Broadly, Reeder said, the oyster felonies are in place for a reason, to deter nefarious, potentially risky activities. ""An oyster can kill you,"" Reeder said, referring to the possible presence of viruses, bacteria and parasites in raw shellfish. ""That’s why we take it seriously."" But Texans rarely face oyster felony charges, Reeder said, because nearly all offenders stop after being charged with a misdemeanor. Statewide in the fiscal year ending Aug. 31, 2012, according to the agency, no such felonies were charged. By telephone, neither Henson nor Levin expressed surprise that no oyster felonies were charged in a recent year or that no one can be charged with such a felony without a prior misdemeanor conviction. With a laugh, Henson said: ""I guess the laws worked. They stamped out oyster crime in Texas."" Henson and Levin each said, too, the oyster felonies demonstrate regulatory issues--such as having a license or fishing in restricted waters--being placed inappropriately into criminal statutes. Levin said there is an opportunity to shrink the number of state crimes starting from a Texas House proposal to create a commission that would recommend changes in advance of the 2015 legislative session. Our ruling Henson said there are 11 Texas felonies one can commit with an oyster. He could have said 16, according to the state’s breakdown of felony offenses, though Parks & Wildlife suggests such  oyster-related crimes break down to seven distinct offenses. Significantly, too, these felony charges are rare. No one can even face one without having previously been convicted of at least one related misdemeanor.s ."
