Reducing Climate Change Uncertainty By Figuring Out Clouds 249

Posted by Soulskill from the look-an-article-about-actual-clouds dept.
Most climate scientists agree that the Earth's climate is getting warmer, but models predicting the severity of the temperature rise span a (relatively) broad range. One big reason for this is the difficulty in modeling things like cloud cover and how different air masses mix and move around each other. "Specifically, they have differences in how water-rich air at the bottom of the atmosphere gets mixed with the layers immediately above it. In some cases, this mixing increases rapidly as the temperature rises, effectively drying out the lower atmosphere and suppressing cloud formation there. This in turn would enhance the warming effect. In others, the increase in mixing is more gradual, limiting the impact of warming on clouds. The former produces a higher climate sensitivity; the latter a lower one. ... So, the authors turned to the atmosphere, using data to determine the relative importance of these processes (abstract). In the end, they find that the models that dry out the lower atmosphere more quickly are likely to get the process right. And, in these models, the mixing increases the drying rate in the lower atmosphere by about five to seven percent for each Kelvin the Earth's temperature increases. In contrast, the rate of evaporation, which adds moisture to the lower atmosphere, only increases by two percent for each Kelvin. Thus, the lower atmosphere dries out, cloud formation there is suppressed, and the planet warms even further. How much more will it warm? Quite a bit."

US Justice Blocks Implementation of ACA Contraceptive Mandate 903

Posted by Unknown Lamer from the can-we-just-have-communist-care-instead? dept.
theodp writes "First approved for contraceptive use in the U.S. in 1960, 'The Pill' is currently used by more than 100 million women worldwide and by almost 12 million women in the U.S. But just hours before the Affordable Care Act was to go into effect, Justice Sonia Sotomayor issued a stay temporarily blocking a mandate requiring health insurance coverage of birth control, and gave the Obama administration until Friday to respond to the Supreme Court on the matter. Sotomayor's order applies to a group of nuns, the Little Sisters of the Poor, and other Roman Catholic nonprofit groups that use the same health plan, known as the Christian Brothers Employee Benefit Trust (PDF). The group is one of many challenging the federal requirement for contraceptive coverage, but a decision on the merits of that case by the full Supreme Court could have broader implications. One imagines Melinda Gates is none too pleased. So, will U.S. health care require a Department of Personal Belief Exemptions that are dictated by employers (PDF, 'The Trustees of CBEBT and the management of Christian Brothers Services are dedicated to protecting the employers participating in the CBEBT from having to face the choice of violating their faith or violating the law')?"

US Light Bulb Phase-Out's Next Step Begins Next Month 1146

Posted by timothy from the word-from-on-high dept.
SonicSpike writes "Light bulb manufacturers will cease making traditional 40 and 60-watt light bulbs — the most popular in the country — at the start of 2014. This comes after the controversial phasing out of incandescent 75 and 100-watt light bulbs at the beginning of 2013. In their place will be halogen bulbs, compact fluorescent bulbs, LED bulbs and high efficiency incandescents — which are just regular incandescents that have the filament wrapped in gas. All are significantly more expensive than traditional light bulbs, but offer significant energy and costs savings over the long run. (Some specialty incandescents — such as three-way bulbs — will still be available.) ... The rules were signed into law by President George W. Bush in 2007. They are designed to address gross inefficiencies with old light bulbs — only 10% of the energy they use is converted into light, according to the Environmental Protection Agency, which has a handy fact sheet about the changes. The rest is wasted as heat. But the rules have drawn fire from a number of circles — mainly conservatives and libertarians who are unhappy about the government telling people what light bulbs they can use. They argue that if the new ones really are so good, people will buy them on their own without being forced to do so."

Employee Morale Is Suffering At the NSA 841

Posted by samzenpus from the turn-that-frown-upside-down dept.
Hugh Pickens DOT Com writes "Ellen Nakashima reports at the Washington Post that morale has taken a hit at the National Security Agency in the wake of controversy over the agency's surveillance activities and officials are dismayed that President Obama has not visited the agency to show his support. 'It is not clear whether or when Obama might travel the 23 miles up the Baltimore-Washington Parkway to visit Fort Meade, the NSA's headquarters in Maryland,' writes Nakashima, 'but agency employees are privately voicing frustration at what they perceive as White House ambivalence amid the pounding the agency has taken from critics.' Though Obama has asserted that the NSA's collection of virtually all Americans' phone records is lawful and has saved lives, the administration has not endorsed legislation that would codify it. And his recent statements suggest Obama thinks some of the NSA's activities should be constrained. 'The agency, from top to bottom, leadership to rank and file, feels that it is had no support from the White House even though it's been carrying out publicly approved intelligence missions,' says Joel Brenner, NSA inspector general from 2002 to 2006. 'They feel they've been hung out to dry, and they're right.' Former officials note how President George W. Bush paid a visit to the NSA in January 2006, in the wake of revelations by the New York Times that the agency engaged in a counterterrorism program of warrantless surveillance on U.S. soil beginning after the Sept. 11, 2001, terrorist attacks. 'Bush came out and spoke to the workforce, and the effect on morale was tremendous,' Brenner said. 'There's been nothing like that from this White House.' Morale is 'bad overall' says another former NSA official. 'It's become very public and very personal. Literally, neighbors are asking people, 'Why are you spying on Grandma?'"

Study Linking GM Maize To Rat Tumors Is Retracted 341

Posted by Soulskill from the arguing-over-food dept.
ananyo writes "Bowing to scientists' near-universal scorn, the journal Food and Chemical Toxicology has fulfilled its threat to retract a controversial paper which claimed that a genetically modified (GM) maize causes serious disease in rats after the authors refused to withdraw it. The paper, from a research group led by Gilles-Eric Séralini, a molecular biologist at the University of Caen, France, and published in 2012, showed 'no evidence of fraud or intentional misrepresentation of the data,' said a statement from Elsevier, which publishes the journal. But the small number and type of animals used in the study means that 'no definitive conclusions can be reached.' The known high incidence of tumors in the Sprague-Dawley rat 'cannot be excluded as the cause of the higher mortality and incidence observed in the treated groups,' it added. Today's move came as no surprise. Earlier this month, the journal's editor-in-chief, Wallace Hayes, threatened retraction if Séralini refused to withdraw the paper, which is exactly what he announced at a press conference in Brussels this morning. Séralini and his team remained unrepentant, and allege that the retraction derives from the journal's editorial appointment of biologist Richard Goodman, who previously worked for biotechnology giant Monsanto for seven years."

Code.org: More Money For CS Instructors Who Teach More Girls 381

Posted by timothy from the achieving-a-particular-balance dept.
theodp writes "The same cast of billionaire characters — Mark Zuckerberg, Bill Gates, Steve Ballmer, Eric Schmidt — is backing FWD.us, which is lobbying Congress for more visas to 'meet our workforce needs,' as well as Code.org, which aims to popularize Computer Science education in the U.S. to address a projected CS job shortfall. In laying out the two-pronged strategy for the Senate, Microsoft General Counsel and Code.org Board member Brad Smith argued that providing more kids with a STEM education — particularly CS — was 'an issue of critical importance to our country.' But with its K-8 learn-to-code program which calls for teachers to receive 25% less money if fewer than 40% of their CS students are girls, Smith's Code.org is sending the message that training too many boys isn't an acceptable solution to the nation's CS crisis. 'When 10 or more students complete the course,' explains Code.org, "you will receive a $750 DonorsChoose.org gift code. If 40% or more of your participating students are female, you'll receive an additional $250, for a total gift of $1,000 in DonorsChoose.org funding!" The $1+ million Code.org-DonorsChoose CS education partnership appears to draw inspiration from a $5 million Google-DoonorsChoose STEM education partnership which includes nebulous conditions that disqualify schools from AP STEM funding if projected participation by female students in AP STEM programs is deemed insufficient. So, are Zuckerberg, Gates, Ballmer, and Schmidt walking-the-gender-diversity-talk at their own companies? Not according to the NY Times, which just reported that women still account for only about 25% of all employees at Code.org supporters Apple, Google, Facebook, and Microsoft. By the way, while not mentioning these specific programs, CNET reports that Slashdot owner Dice supports the STEM efforts of Code.org and Donors Choose."

The US Now Faces the Same Dilemma Over Drones As It Did Over Nuclear Weapons 211

Posted by Soulskill from the what-did-we-learn dept.
Lasrick writes "Hugh Gusterson examines the crossroads at which the U.S. finds itself on the use of drones, and the long-term consequences of choices made now, by looking at the history of choices the U.S. made in the 1940s regarding nuclear weapons. Thoughtful read. Quoting: 'Having seen what drones are capable of, political leaders can choose to place clear limits, domestically and internationally, on how they can be used. Or, telling the American people that drones will make them safer or that "you can’t stop technology," they can allow free rein to those military inventors, national security bureaucrats and industry entrepreneurs eager to develop drone technology as aggressively as possible. Such people are impatient to press ahead with new unmanned aerial vehicles, including smart drones and mini-drones, to sell both to the US military for use overseas and to law-enforcement bodies within the United States. If drone development continues unchecked, what can we expect? First, as with nuclear weapons, proliferation. At the moment the United States, Britain, and Israel are the only countries to have used weaponized drones. But many countries, including Russia and China, have been watching carefully as Washington has experimented with counterinsurgency by drone, and are considering how they might use this relatively cheap technology for their own purposes. If they decide to use their own drones outside the boundaries of international law against people they brand “terrorists,” the United States will hardly be in a position to condemn them or counsel restraint.'"

Fukushima Disaster Leads Japan To Backpedal On Emissions Pledge 274

Posted by timothy from the feeling-electricity's-pull dept.
mdsolar writes with this excerpt from the New York Times: "Japan took a major step back on Friday from earlier pledges to slash its greenhouse gas emissions, saying a shutdown of its nuclear power plants in the wake of the Fukushima disaster had made previous targets unattainable. The announcement cast a shadow over international talks underway in Warsaw aimed at fashioning a new global pact to address the threats of a changing climate. Under its new goal, Japan, one of the world's top polluters, would still seek to reduce its current emissions. But it would release 3 percent more greenhouse gases in 2020 than it did in 1990, rather than the 6 percent cut it originally promised or the 25 percent reduction it promised two years before the 2011 nuclear disaster."
