In Historic Turn, CO2 Emissions Flatline In 2014, Even As Global Economy Grows 283

mdsolar sends this report from Forbes: A key stumbling block in the effort to combat global warming has been the intimate link between greenhouse gas emissions and economic growth. When times are good and industries are thriving, global energy use traditionally increases and energy-related carbon dioxide emissions also go up. Only when economies stumble and businesses shutter — as during the most recent financial crisis — does energy use typically decline, in turn bringing down planet-warming emissions.

But for the first time in nearly half a century, that synchrony between economic growth and energy-related emissions seems to have been broken, according to the Paris-based International Energy Agency, prompting its chief economist to wonder if an important new pivot point has been reached — one that decouples economic vigor and carbon pollution. The IEA pegged carbon dioxide emissions for 2014 at 32.3 billion metric tons — essentially the same volume as 2013, even as the global economy grew at a rate of about 3 percent. Whether the disconnect is a mere fluke or a true harbinger of a paradigm shift is impossible to know. The IEA suggested that decreasing use of coal in China — and upticks in renewable electricity generation there using solar, wind and hydropower — could have contributed to the reversal.

Comment Re:Slightly misleading. (Score 1) 226

Because unlike in Canada where Canada Post control their own rates, postal rates in the USA are controlled by Congress, several members of which have interest in sabotaging the USPS.

It seems this is not correct. The Board of Governors of the United States Postal Service and the Postal Regulatory Commission set and oversee postal rates respectively [1]. Ultimately Congress can pass a law changing the structure, but that is no different than Parliament overruling Canada Post, so it appears that the distinction you highlighted between the two postal systems does not exist.

Or a short pulse is generated by a shorting circuit making a 0 0 0 0 0 0 0 ... which gets to a count of 8 of them. BOOM!

This is actually far from hypothetical. Quoting Lee Earnest (http://www.stanford.edu/~learnest/gump.htm):

In 1960, I somehow was assigned the responsibility of leading a study group to get approval for putting nuclear warheads on the second-generation BOMARC ground-to-air missiles. This involved proving to a government nuclear safety board in Albuquerque, New Mexico, that the probability of accidentally launching a missile on any given day as a result of system malfunctions was less than a certain very small number and that one person couldn't do it by himself. [...]

The SAGE system used land lines to transmit launch commands to the missile sites and, since these lines were duplexed, a black box at each missile site was set up to detect when the primary line went bad so that it could switch to the backup. However on examination we noticed that if both lines went bad concurrently the system would remain connected to the backup line and the amplifiers would then pick up and amplify whatever noise was there and interpret it as a stream of random bits.

[...] [a team member] did a Markov analysis to determine the expected time that it would take for a random bit stream to generate a Fire command for one of the missiles. He found that it was a little over two minutes and, when such a command was received, the missile would erect and prepare to launch. However, unless the missile also received a full set of guidance commands during the launch window of about five minutes, it would automatically abort.

So there it is. Nothing but random noise was all that is needed to erect and ready a nuclear-tipped missile. Although it wouldn't launch, that is probably small comfort to those near these things when they do pop up.

Is this the same Pearson that designs and administers tests for IT and other professional certifications? If so, it would explain a lot. The ones I've taken seem to be designed not to test your skills in the subject matter, so much as to test your capacity to parse bad English and to solve trick questions.

The subject matter is important, agreed. However, parsing bad English and dealing with trick questions are necessary professional skills in this age.

Although I doubt it was Pearson's intention to test those dimensions.

'Half' of 2012's Extreme Weather Impacted By Climate Change 417

sciencehabit writes "2012 was a year of extreme weather: Superstorm Sandy, drought and heat waves in the United States; record rainfall in the United Kingdom; unusually heavy rains in Kenya, Somalia, Japan, and Australia; drought in Spain; floods in China. One of the first questions asked in the wake of such extreme weather is: 'Could this due to climate change?' In a report (huge PDF) published online today, NOAA scientists tackled this question head-on. The overall message of the report: It varies. 'About half of the events reveal compelling evidence that human-caused change was a [contributing] factor,' said NOAA National Climatic Data Center Director Thomas Karl. In addition, climate scientist Peter Stott of the U.K. Met Office noted that these studies show that in many cases, human influence on climate has increased the risks associated with extreme events."

UC Davis Investigates Using Helicopter Drones For Crop Dusting 77

cylonlover writes "Researchers at University of California, Davis, in cooperation with the Yamaha Motor Corporation, are testing UAV crop dusting on the Oakville Experimental Vineyard at the UC Oakville Station using a Yamaha RMax remote-controlled helicopter. The purpose is to study the adaptation of Japanese UAV crop dusting techniques for US agriculture, but not all the hurdles they face are technological."

I'm skeptical as well. From http://en.wikipedia.org/w/index.php?title=San_Onofre_Nuclear_Generating_Station&oldid=560938909#NRC_response

In May 2012, two retired natural gas electrical generators were brought back online to help replace the lost power generation capacity: the Huntington Beach Power Station, which produces 440MW of power,[47][48] and the Encina Power Station which provides 965MW; coupled with new conservation measures, this has helped keep power available to San Diego and Riverside counties.[49]

So the "forward-looking planning" seems to rely on two mothballed power stations. Was this *actually* part of some government and/or utility plan, and these two plants were held in reserve as a contingency? Or is it more that they planned to look forward to saying "oh crap" and quickly scrambling to find a stopgap solution?

Snowden NSA Claims Partially Confirmed, Says Rep. Jerrold Nadler 337

bill_mcgonigle writes with this news from from CNET: "Rep. Jerrold Nadler (D NY) disclosed that NSA analysts eavesdrop on Americans' domestic telephone calls without court orders during a House Judiciary hearing. After clearing with FBI director Robert Mueller that the information was not classified, Nadler revealed that during a closed-door briefing to Congress, the Legislature was informed that the spying organization had implemented and uses this capability. This appears to confirm Edward Snowden's claim that he could, in his position at the NSA, 'wiretap anyone from you or your accountant to a federal judge to even the president.' Declan McCullagh writes, 'Because the same legal standards that apply to phone calls also apply to e-mail messages, text messages, and instant messages, Nadler's disclosure indicates the NSA analysts could also access the contents of Internet communications without going before a court and seeking approval.' The executive branch has defended its general warrants, claiming that 'the president had the constitutional authority, no matter what the law actually says, to order domestic spying without [constitutional] warrants,' while Kurt Opsahl, senior staff attorney at EFF claims such government activity 'epitomizes the problem of secret laws.'" Note that "listening in" versus "collecting metadata" is a distinction that defenders of government phone spying have been emphasizing. Tracking whom you called and when, goes the story, doesn't impinge on expectations of privacy. Speaking of the metadata collection, though, reader Bruce66423 writes "According to the Washington Post, the Bush administration took 'bulk metadata' from the phone companies under voluntary agreements for more than four years after 9/11 until a court agreed they could have it compulsorily." Related: First time accepted submitter fsagx writes that Brewster Kahle of the Internet Archive has calculated the cost to store every phone call made in the U.S. over the course of a year: "It's surprisingly inexpensive. It puts the recent NSA stories (and reports from the Boston bombings about the FBI's ability to listen to past phone conversions) into perspective."

Because if they raise the limit to 75, people will drive 85. Americans have been conditioned to believe that the "real" speed limit is at least 10 mph over the posted limit.

That is an interesting point so I did some research. I found FHWA Report No. FHWA-RD-92-084 (one source of which is at http://www.ibiblio.org/rdu/sl-irrel.html but other copies agree) that says "The results of the study indicated that lowering posted speed limits by as much as 20 mi/h (32 km/h), or raising speed limits by as much as 15 mi/h (24 km/h) had little effect on motorist' speed."

I'm curious if you had any citations to confirm your statement.

While I agree with the Senator, I believe we must act with comprehensive reform. Laser printers are being used to print counterfeit money. Those too should be regulated and tracked just as strictly as 3d printers. All printer owners should be tracked, registered, and of course, pay a government tax to cover all this tracking.

From the article it isn't clear exactly what information was deemed sensitive. Does this information include very specific details (like, "here is the password to that plant's SCADA system?" Or does it cover broader details that the public had free access to prior to the September 11 attacks, such information now being withheld as "critical infrastructure information?"
