Excerpt from universetoday.com



The first of two eclipse seasons for the year is upon us this month, and kicks off with the only total solar eclipse for 2015 on Friday, March 20th.

And what a bizarre eclipse it is. Not only does this eclipse begin just 15 hours prior to the March equinox marking the beginning of astronomical spring in the northern hemisphere, but the shadow of totality also beats path through the high Arctic and ends over the North Pole.

Already, umbraphiles — those who chase eclipses — are converging on the two small tracts of terra firma where the umbra of the Moon makes landfall: the Faroe and Svalbard islands. All of Europe, the northern swath of the African continent, north-central Asia and the Middle East will see a partial solar eclipse, and the eclipse will be deeper percentage-wise the farther north you are .
2015 features four eclipses in all: two total lunars and two solars, with one total solar and one partial solar eclipse. Four is the minimum number of eclipses that can occur in a calendar year, and although North America misses out on the solar eclipse action this time ’round, most of the continent gets a front row seat to the two final total lunar eclipses of the ongoing tetrad on April 4th and September 28th.

How rare is a total solar eclipse on the vernal equinox? Well, the last total solar eclipse on the March equinox occurred back in 1662 on March 20th. There was also a hybrid eclipse — an eclipse which was annular along a portion of the track, and total along another — on March 20th, 1681. But you won’t have to wait that long for the next, as another eclipse falls on the northward equinox on March 20th, 2034.

Note that in the 21st century, the March equinox falls on March 20th, and will start occasionally falling on March 19th in 2044. We’re also in that wacky time of year where North America has shifted back to ye ‘ole Daylight Saving (or Summer) Time, while Europe makes the change after the eclipse on March 29th. It really can wreak havoc with those cross-time zone plans, we know…
The March 20th eclipse also occurs only a day after lunar perigee, which falls on March 19th at 19:39 UT. This is also one of the closer lunar perigees for 2015 at 357,583 kilometres distant, though the maximum duration of totality for this eclipse is only 2 minutes and 47 seconds just northeast of the Faroe Islands.

This eclipse is number 61 of 71 in solar saros series 120, which runs from 933 to 2754 AD. It’s also the second to last total in the series, with the final total solar eclipse for the saros cycle occurring one saros later on March 30th, 2033.



What would it look like to sit at the North Pole and watch a total solar eclipse on the first day of Spring? It would be a remarkable sight, as the disk of the Sun skims just above the horizon for the first time since the September 2014 equinox. Does this eclipse occur at sunrise or sunset as seen from the pole? It would be a rare spectacle indeed!

Safety is paramount when observing the Sun and a solar eclipse. Eye protection is mandatory during all partial phases across Europe, northern Asia, North Africa and the Middle East. A proper solar filter mask constructed of Baader safety film is easy to construct, and should fit snugly over the front aperture of a telescope. No. 14 welder’s goggles are also dense enough to look at the Sun, as are safety glasses specifically designed for eclipse viewing. Observing the Sun via projection or by using a pinhole projector is safe and easy to do.

Weather is always the big variable in the days leading up to any eclipse. Unfortunately, March in the North Atlantic typically hosts stormy skies, and the low elevation of the eclipse in the sky may hamper observations as well. From the Faroe Islands, the Sun sits 18 degrees above the horizon during totality, while from the Svalbard Islands it’s even lower at 12 degrees in elevation. Much of Svalbard is also mountainous, making for sunless pockets of terrain that will be masked in shadow on eclipse day. Mean cloud amounts for both locales run in the 70% range, and the Eclipser website hosts a great in-depth climatology discussion for this and every eclipse.

But don’t despair: you only need a clear view of the Sun to witness an eclipse!

Solar activity is also another big variable. Witnesses to the October 23rd, 2014 partial solar eclipse over the U.S. southwest will recall that we had a massive and very photogenic sunspot turned Earthward at the time. The Sun has been remarkably calm as of late, though active sunspot region 2297 is developing nicely. It will have rotated to the solar limb come eclipse day, and we should have a good grasp on what solar activity during the eclipse will look like come early next week.

And speaking of which: could an auroral display be in the cards for those brief few minutes of totality? It’s not out of the question, assuming the Sun cooperates.  Of course, the pearly white corona of the Sun still gives off a considerable amount of light during totality, equal to about half the brightness of a Full Moon. Still, witnessing two of nature’s grandest spectacles — a total solar eclipse and the aurora borealis — simultaneously would be an unforgettable sight, and to our knowledge, has never been documented!

We also put together some simulations of the eclipse as seen from Earth and space:




Note that an area of southern Spain may witness a transit of the International Space Station during the partial phase of the eclipse. This projection is tentative, as the orbit of the ISS evolves over time. Be sure to check CALSky for accurate predictions in the days leading up to the eclipse.

Why science is so hard to believe?

 
In the recent movie “Interstellar,” set in a futuristic, downtrodden America where NASA has been forced into hiding, school textbooks say the Apollo moon landings were faked.


Excerpt from 


There’s a scene in Stanley Kubrick’s comic masterpiece “Dr. Strangelove” in which Jack D. Ripper, an American general who’s gone rogue and ordered a nuclear attack on the Soviet Union, unspools his paranoid worldview — and the explanation for why he drinks “only distilled water, or rainwater, and only pure grain alcohol” — to Lionel Mandrake, a dizzy-with-anxiety group captain in the Royal Air Force.
Ripper: “Have you ever heard of a thing called fluoridation? Fluoridation of water?”
Mandrake: “Ah, yes, I have heard of that, Jack. Yes, yes.”Ripper: “Well, do you know what it is?”
Mandrake: “No. No, I don’t know what it is, no.”
Ripper: “Do you realize that fluoridation is the most monstrously conceived and dangerous communist plot we have ever had to face?” 

The movie came out in 1964, by which time the health benefits of fluoridation had been thoroughly established and anti-fluoridation conspiracy theories could be the stuff of comedy. Yet half a century later, fluoridation continues to incite fear and paranoia. In 2013, citizens in Portland, Ore., one of only a few major American cities that don’t fluoridate, blocked a plan by local officials to do so. Opponents didn’t like the idea of the government adding “chemicals” to their water. They claimed that fluoride could be harmful to human health.

Actually fluoride is a natural mineral that, in the weak concentrations used in public drinking-water systems, hardens tooth enamel and prevents tooth decay — a cheap and safe way to improve dental health for everyone, rich or poor, conscientious brushers or not. That’s the scientific and medical consensus.
To which some people in Portland, echoing anti-fluoridation activists around the world, reply: We don’t believe you.
We live in an age when all manner of scientific knowledge — from the safety of fluoride and vaccines to the reality of climate change — faces organized and often furious opposition. Empowered by their own sources of information and their own interpretations of research, doubters have declared war on the consensus of experts. There are so many of these controversies these days, you’d think a diabolical agency had put something in the water to make people argumentative.
Science doubt has become a pop-culture meme. In the recent movie “Interstellar,” set in a futuristic, downtrodden America where NASA has been forced into hiding, school textbooks say the Apollo moon landings were faked.


The debate about mandated vaccinations has the political world talking. A spike in measles cases nationwide has President Obama, lawmakers and even potential 2016 candidates weighing in on the vaccine controversy. (Pamela Kirkland/The Washington Post)
In a sense this is not surprising. Our lives are permeated by science and technology as never before. For many of us this new world is wondrous, comfortable and rich in rewards — but also more complicated and sometimes unnerving. We now face risks we can’t easily analyze.
We’re asked to accept, for example, that it’s safe to eat food containing genetically modified organisms (GMOs) because, the experts point out, there’s no evidence that it isn’t and no reason to believe that altering genes precisely in a lab is more dangerous than altering them wholesale through traditional breeding. But to some people, the very idea of transferring genes between species conjures up mad scientists running amok — and so, two centuries after Mary Shelley wrote “Frankenstein,” they talk about Frankenfood.
The world crackles with real and imaginary hazards, and distinguishing the former from the latter isn’t easy. Should we be afraid that the Ebola virus, which is spread only by direct contact with bodily fluids, will mutate into an airborne super-plague? The scientific consensus says that’s extremely unlikely: No virus has ever been observed to completely change its mode of transmission in humans, and there’s zero evidence that the latest strain of Ebola is any different. But Google “airborne Ebola” and you’ll enter a dystopia where this virus has almost supernatural powers, including the power to kill us all.
In this bewildering world we have to decide what to believe and how to act on that. In principle, that’s what science is for. “Science is not a body of facts,” says geophysicist Marcia McNutt, who once headed the U.S. Geological Survey and is now editor of Science, the prestigious journal. “Science is a method for deciding whether what we choose to believe has a basis in the laws of nature or not.”
The scientific method leads us to truths that are less than self-evident, often mind-blowing and sometimes hard to swallow. In the early 17th century, when Galileo claimed that the Earth spins on its axis and orbits the sun, he wasn’t just rejecting church doctrine. He was asking people to believe something that defied common sense — because it sure looks like the sun’s going around the Earth, and you can’t feel the Earth spinning. Galileo was put on trial and forced to recant. Two centuries later, Charles Darwin escaped that fate. But his idea that all life on Earth evolved from a primordial ancestor and that we humans are distant cousins of apes, whales and even deep-sea mollusks is still a big ask for a lot of people.
Even when we intellectually accept these precepts of science, we subconsciously cling to our intuitions — what researchers call our naive beliefs. A study by Andrew Shtulman of Occidental College showed that even students with an advanced science education had a hitch in their mental gait when asked to affirm or deny that humans are descended from sea animals and that the Earth goes around the sun. Both truths are counterintuitive. The students, even those who correctly marked “true,” were slower to answer those questions than questions about whether humans are descended from tree-dwelling creatures (also true but easier to grasp) and whether the moon goes around the Earth (also true but intuitive).
Shtulman’s research indicates that as we become scientifically literate, we repress our naive beliefs but never eliminate them entirely. They nest in our brains, chirping at us as we try to make sense of the world.
Most of us do that by relying on personal experience and anecdotes, on stories rather than statistics. We might get a prostate-specific antigen test, even though it’s no longer generally recommended, because it caught a close friend’s cancer — and we pay less attention to statistical evidence, painstakingly compiled through multiple studies, showing that the test rarely saves lives but triggers many unnecessary surgeries. Or we hear about a cluster of cancer cases in a town with a hazardous-waste dump, and we assume that pollution caused the cancers. Of course, just because two things happened together doesn’t mean one caused the other, and just because events are clustered doesn’t mean they’re not random. Yet we have trouble digesting randomness; our brains crave pattern and meaning.
Even for scientists, the scientific method is a hard discipline. They, too, are vulnerable to confirmation bias — the tendency to look for and see only evidence that confirms what they already believe. But unlike the rest of us, they submit their ideas to formal peer review before publishing them. Once the results are published, if they’re important enough, other scientists will try to reproduce them — and, being congenitally skeptical and competitive, will be very happy to announce that they don’t hold up. Scientific results are always provisional, susceptible to being overturned by some future experiment or observation. Scientists rarely proclaim an absolute truth or an absolute certainty. Uncertainty is inevitable at the frontiers of knowledge.
That provisional quality of science is another thing a lot of people have trouble with. To some climate-change skeptics, for example, the fact that a few scientists in the 1970s were worried (quite reasonably, it seemed at the time) about the possibility of a coming ice age is enough to discredit what is now the consensus of the world’s scientists: The planet’s surface temperature has risen by about 1.5 degrees Fahrenheit in the past 130 years, and human actions, including the burning of fossil fuels, are extremely likely to have been the dominant cause since the mid-20th century.
It’s clear that organizations funded in part by the fossil-fuel industry have deliberately tried to undermine the public’s understanding of the scientific consensus by promoting a few skeptics. The news media gives abundant attention to such mavericks, naysayers, professional controversialists and table thumpers. The media would also have you believe that science is full of shocking discoveries made by lone geniuses. Not so. The (boring) truth is that science usually advances incrementally, through the steady accretion of data and insights gathered by many people over many years. So it has with the consensus on climate change. That’s not about to go poof with the next thermometer reading.
But industry PR, however misleading, isn’t enough to explain why so many people reject the scientific consensus on global warming.
The “science communication problem,” as it’s blandly called by the scientists who study it, has yielded abundant new research into how people decide what to believe — and why they so often don’t accept the expert consensus. It’s not that they can’t grasp it, according to Dan Kahan of Yale University. In one study he asked 1,540 Americans, a representative sample, to rate the threat of climate change on a scale of zero to 10. Then he correlated that with the subjects’ science literacy. He found that higher literacy was associated with stronger views — at both ends of the spectrum. Science literacy promoted polarization on climate, not consensus. According to Kahan, that’s because people tend to use scientific knowledge to reinforce their worldviews.
Americans fall into two basic camps, Kahan says. Those with a more “egalitarian” and “communitarian” mind-set are generally suspicious of industry and apt to think it’s up to something dangerous that calls for government regulation; they’re likely to see the risks of climate change. In contrast, people with a “hierarchical” and “individualistic” mind-set respect leaders of industry and don’t like government interfering in their affairs; they’re apt to reject warnings about climate change, because they know what accepting them could lead to — some kind of tax or regulation to limit emissions.
In the United States, climate change has become a litmus test that identifies you as belonging to one or the other of these two antagonistic tribes. When we argue about it, Kahan says, we’re actually arguing about who we are, what our crowd is. We’re thinking: People like us believe this. People like that do not believe this.
Science appeals to our rational brain, but our beliefs are motivated largely by emotion, and the biggest motivation is remaining tight with our peers. “We’re all in high school. We’ve never left high school,” says Marcia McNutt. “People still have a need to fit in, and that need to fit in is so strong that local values and local opinions are always trumping science. And they will continue to trump science, especially when there is no clear downside to ignoring science.”
Meanwhile the Internet makes it easier than ever for science doubters to find their own information and experts. Gone are the days when a small number of powerful institutions — elite universities, encyclopedias and major news organizations — served as gatekeepers of scientific information. The Internet has democratized it, which is a good thing. But along with cable TV, the Web has also made it possible to live in a “filter bubble” that lets in only the information with which you already agree.
How to penetrate the bubble? How to convert science skeptics? Throwing more facts at them doesn’t help. Liz Neeley, who helps train scientists to be better communicators at an organization called Compass, says people need to hear from believers they can trust, who share their fundamental values. She has personal experience with this. Her father is a climate-change skeptic and gets most of his information on the issue from conservative media. In exasperation she finally confronted him: “Do you believe them or me?” She told him she believes the scientists who research climate change and knows many of them personally. “If you think I’m wrong,” she said, “then you’re telling me that you don’t trust me.” Her father’s stance on the issue softened. But it wasn’t the facts that did it.
If you’re a rationalist, there’s something a little dispiriting about all this. In Kahan’s descriptions of how we decide what to believe, what we decide sometimes sounds almost incidental. Those of us in the science-communication business are as tribal as anyone else, he told me. We believe in scientific ideas not because we have truly evaluated all the evidence but because we feel an affinity for the scientific community. When I mentioned to Kahan that I fully accept evolution, he said: “Believing in evolution is just a description about you. It’s not an account of how you reason.”
Maybe — except that evolution is real. Biology is incomprehensible without it. There aren’t really two sides to all these issues. Climate change is happening. Vaccines save lives. Being right does matter — and the science tribe has a long track record of getting things right in the end. Modern society is built on things it got right.
Doubting science also has consequences, as seen in recent weeks with the measles outbreak that began in California. The people who believe that vaccines cause autism — often well educated and affluent, by the way — are undermining “herd immunity” to such diseases as whooping cough and measles. The anti-vaccine movement has been going strong since a prestigious British medical journal, the Lancet, published a study in 1998 linking a common vaccine to autism. The journal later retracted the study, which was thoroughly discredited. But the notion of a vaccine-autism connection has been endorsed by celebrities and reinforced through the usual Internet filters. (Anti-vaccine activist and actress Jenny McCarthy famously said on “The Oprah Winfrey Show,” “The University of Google is where I got my degree from.”)
In the climate debate, the consequences of doubt are likely to be global and enduring. Climate-change skeptics in the United States have achieved their fundamental goal of halting legislative action to combat global warming. They haven’t had to win the debate on the merits; they’ve merely had to fog the room enough to keep laws governing greenhouse gas emissions from being enacted.
Some environmental activists want scientists to emerge from their ivory towers and get more involved in the policy battles. Any scientist going that route needs to do so carefully, says Liz Neeley. “That line between science communication and advocacy is very hard to step back from,” she says. In the debate over climate change, the central allegation of the skeptics is that the science saying it’s real and a serious threat is politically tinged, driven by environmental activism and not hard data. That’s not true, and it slanders honest scientists. But the claim becomes more likely to be seen as plausible if scientists go beyond their professional expertise and begin advocating specific policies.
It’s their very detachment, what you might call the cold-bloodedness of science, that makes science the killer app. It’s the way science tells us the truth rather than what we’d like the truth to be. Scientists can be as dogmatic as anyone else — but their dogma is always wilting in the hot glare of new research. In science it’s not a sin to change your mind when the evidence demands it. For some people, the tribe is more important than the truth; for the best scientists, the truth is more important than the tribe.

Google Chairman Eric Schmidt: "The Internet Will Disappear"


 


Excerpt from hollywoodreporter.com

Google executive chairman Eric Schmidt on Thursday predicted the end of the Internet as we know it.

At the end of a panel at the World Economic Forum in Davos, Switzerland, where his comments were webcast, he was asked for his prediction on the future of the web. “I will answer very simply that the Internet will disappear,” Schmidt said.

“There will be so many IP addresses…so many devices, sensors, things that you are wearing, things that you are interacting with that you won’t even sense it,” he explained. “It will be part of your presence all the time. Imagine you walk into a room, and the room is dynamic. And with your permission and all of that, you are interacting with the things going on in the room.”

Concluded Schmidt: “A highly personalized, highly interactive and very, very interesting world emerges.”

The panel, entitled The Future of the Digital Economy, also featured Facebook COO Sheryl Sandberg and others.
Earlier in the debate, Schmidt discussed the issue of market dominance. The European Union has been looking at Google’s search market dominance in a long-running antitrust case, and the European parliament late last year even called for a breakup.
“You now see so many strong tech platforms coming, and you are seeing a reordering and a future reordering of dominance or leaders or whatever term you want to use because of the rise of the apps on the smartphone,” Schmidt said Thursday. “All bets are off at this point as to what the smartphone app infrastructure is going to look like” as a “whole new set” of players emerges to power smartphones, which are nothing but super-computers, the Google chairman argued. “I view that as a completely open market at this point.”

Asked about his recent trip to North Korea, Schmidt said the country has many Internet connections through data phones, but there is no roaming and web usage is “heavily supervised.” Schmidt said “it’s very much surveillance of use,” which he said was not good for the country and others.

Sandberg and Schmidt lauded the Internet as an important way to give more people in the world a voice. Currently, only 40 percent of people have Internet access, the Facebook COO said, adding that any growth in reach helps extend people’s voice and increase economic opportunity. “I’m a huge optimist,” she said about her outlook for the industry. “Imagine what we can do” once the world gets to 50 percent, 60 percent and more in terms of Internet penetration.
She cited women as being among the beneficiaries, saying the Internet narrows divides.

Schmidt similarly said that broadband can address governance issues, information needs, personal issues, women empowerment needs and education issues. “The Internet is the greatest empowerment of citizens … in many years,” he said. “Suddenly citizens have a voice, they can be heard.”
During another technology panel at the World Economic Forum on Thursday, Yahoo CEO Marissa Mayer, Liberty Global CEO Mike Fries and others answered questions on the need to regulate privacy standards on the Internet and for tech companies following the Snowden case, the Sony hack and the like.


Mayer said that the personalized Internet “is a better Internet,” emphasizing: “We don’t sell your personal data … We don’t transfer your personal data to third parties.” She said users own their data and need to have control, adding that people give up data to the government for tax assessment, social services and other purposes.
Fries said Liberty Global subscribers view billions of hours of content and generate billions of clicks, but added that “today we do nothing.” He explained: “We generate zero revenue from all of that information.” But he acknowledged that big data was big business for a lot of people.

Both executives said transparency was important to make sure users know privacy standards and the like.

Gunther Oettinger, a conservative German politician serving as the European Union’s commissioner for digital economy and society, said on the panel that “we need a convincing global understanding, we need a UN agency for data protection and security.” Asked what form that “understanding” should have, he said he was looking for “clear, pragmatic, market-based regulation.” Explained Oettinger: “It’s a public-private partnership.”

Fries said such a solution was likely not to happen in the near term, given the size of the EU. “I think it is going to take several years,” he said, adding that some countries’ parliaments would likely take a stab at it.

But he warned that a joint solution would make more sense. “We don’t want Germany to have its own Internet,” Fries said. “Some countries may build their own Internets” and “balkanize” the web, he warned.

Mayer said on the issue of regulation: “I like Tim’s idea better of the beneficent marketplace.” She spoke of fellow panelist and computer specialist Tim Berners-Lee, known as the inventor of the World Wide Web.

Asked how Yahoo stores and handles client records, she said the online giant “changed the way we store and communicate data” after Snowden and also changed encryptions between data centers. And the company protects users through encryption methods, she added. Mayer said that trust and confidence of Yahoo users has rebounded since.

Mayer was also asked what happens if a government asks for a user’s data, a question that has new significance after the recent terrorist attacks in Paris, which have led some to call for increased surveillance powers of the Internet for governments. Mayer said Yahoo always assesses if such a request is reasonable. “We have a very good track record for standing up to what’s not reasonable,” she said.

Spacecraft found on Mars – and it’s ours

Croon had asked for specific camera targeting through a program called HiWish, through which anyone can submit suggestions for HiRISE images. Read more about this fascinating sleuthing story.
"Not knowing what happened to Beagle 2 remained a nagging worry," comments Rudolf Schmidt in an ESA press release about the find. "Understanding now that Beagle 2 made it all the way down to the surface is excellent news." Schmidt served as the Mars Express project manager at the time.
Built by a consortium of organizations, Beagle 2 was the United Kingdom's first interplanetary spacecraft. The 32-kg (73-pound) lander carried six instruments to study geochemical characteristics of the Martian surface and to test for the presence of life using assays of carbon isotopes. It was named for HMS Beagle, the ship that carried a crew of 73 (including Charles Darwin) on an epic voyage of discovery in 1831–36.

4 Sky Events This Week: Inner Planets Dance While Saturn Dazzles

Excerpt from news.nationalgeographic.com

An eclipse of a volcanic moon by the king of planets, Jupiter, will thrill stargazers this week, as Earth's moon rides above the ringed world, Saturn.

Moon meets Maiden. On Tuesday, January 13, early birds will enjoy a particularly close encounter with the last quarter moon of the month and with the bright star Spica. All the action takes place in the constellation Virgo, the Maiden, halfway up the southern sky at dawn.

The 250-light-year-distant star appears only 2 degrees below the moon, a distance equal to about the width of your thumb held at arm's length.

It's amazing to realize that the light from Spica left on its journey to Earth back in 1765. That's the year that Great Britain passed the Stamp Act, the first direct tax levied on the American colonies and a prelude of the parliamentary oversteps that led to the American Revolution.

Mercury at its best. Look for faint Mercury about a half-hour after sunset on Wednesday, January 14, just above the southwestern horizon.

The innermost planet will appear at its farthest point away from the sun, a moment called the greatest elongation. Sitting 19 degrees east of the sun, it would be challenging to track down its faint point of light if it weren't for the nearby, superbright Venus.

The planetary duo will appear only 1.3 degrees apart, making the pair particularly impressive when viewed through binoculars or a small telescope. Look carefully and you may notice that Mercury appears to be a miniature version of the half-lit moon...

Volcanic moon eclipse. Sky-watchers armed with telescopes will witness a distant eclipse of Jupiter's moon Io in the early morning hours of Friday, January 16.

At 12:27 a.m. EST, the gas giant's own shadow will glide across the tiny disk of the volcanic moon, which will be visible to the west of the planet.

Also early on Thursday night at 10:56 p.m. EST, Jupiter's massive storm, the Great Red Spot, crosses the middle of the planet's disk. Appearing as an orange-pink oval structure, this hurricane circles the planet every 12 hours or so and is three times larger than the Earth.

Luna and Saturn. Later on, near dawn on Friday, January 16, the waning crescent moon will appear to park itself just 2 degrees north of Lord of the Rings.

The ringed world can't be missed with the naked eye since it is the brightest object visible in the southeastern predawn sky. Its proximity to the moon will make it that much easier to identify.
Train a telescope on this yellow-tinged point of light, and it will readily reveal its stunning rings, tilted a full 25 degrees toward Earth. Currently Saturn sits nearly 994,000 miles (1.6 billion kilometers) away from Earth, which means that the reflected sunlight off its cloud tops takes 87.4 minutes to reach our eyes.
Happy hunting!

California breaks ground on bullet train project despite opposition, as price tag soars





Excerpt from foxnews.com

Despite cost overruns, lawsuits, public opposition and a projected completion date 13 years behind schedule, California Gov. Jerry Brown broke ground Tuesday on what is to become the most expensive public works project in U.S. history: the California bullet train. 

Over the next 1,000 days, California is estimated to spend roughly $4 million a day on the project. 

The high-speed train, set to be finished in 2033, originally was supposed to deliver passengers from San Francisco to Los Angeles in two hours and 40 minutes. That was the promise when voters narrowly approved $10 billion in bonds for the project in 2008. Since then, however, the estimated trip time has grown considerably, and the train has encountered persistent problems -- as experts uncovered misrepresentations in the ballot proposition, and opponents sued to stop the project on environmental and fiscal grounds. 

"We're talking about real money here," said Kris Vosburgh, executive director of taxpayer watchdog group Howard Jarvis Taxpayers Association. "This is money that's not available for health care or education, for public safety, or put back in taxpayers' pockets so they have something to spend. This is money being drawn out of the system for a program that is going to serve very few people." 

Much about the project has changed since it was sold to the public. 
Voters were told the project would cost just $33 billion. Once experts crunched the numbers, however, the price tag soared to $98 billion. It was supposed to whoosh riders from Southern California to the Bay Area in less than three hours, but now it’s more than four hours due to changing track configurations and route adjustments. The train was supposed to get people off the freeway and reduce carbon emissions, but a panel of experts now says any carbon savings will be nominal. (A drive by car takes just over 6 hours. Ed.) 

Further, ridership projections have been cut by two-thirds from a projected 90 million to 30 million a year. Fewer riders means higher prices. According to a panel of transportation experts hired by the Reason Foundation, Citizens Against Government Waste and the Howard Jarvis Taxpayers Association, tickets will exceed $80 -- not $50 -- and the system will require annual subsidies of more than $300 million annually. 

"The public has turned sour on this plan but the governor, to paraphrase Admiral Farragut, has taken a position of 'damn the people, full speed ahead'," Vosburgh said. 

Undaunted by critics, Brown broke ground in Fresno on Tuesday on the first 29-mile segment of the train's system. Under Brown's direction, the California High Speed Rail Authority has gone to court to seek an exemption from an environmental quality law the state imposes on other projects but not this one. Brown also convinced the state Legislature to dedicate an annual revenue stream from the state's carbon tax, to help pay for the bullet train. 
"It's a long project, a bold project and one that will transform the Central Valley," Brown said Monday as he began his fourth and final term as governor. 

Once construction begins, supporters say it will be harder to stop the project. Several lawsuits linger, but a bigger question concerns the money: Where will it come from? If every penny committed to the project is added up, the project is still more than $30 billion short. Republicans in Congress are vowing not to commit a dollar more than President Obama approved in 2012. 

"For years now, Governor Brown and the high-speed rail authority have turned the idea of high-speed rail into a public albatross far beyond what Californians envisioned or voted for," House Majority Leader Kevin McCarthy, R-Calif., said in a statement released Tuesday. "Sadly, today's groundbreaking is a political maneuver. Supporters of the railroad in Sacramento can't admit their project is deeply flawed, and they won't give up on it despite the cost. But these political tricks are exactly what the American people are tired of and what the new Republican Congress is committed to ending." 

Supporters don't see waste. They argue the project will reduce freeway gridlock, offer competition to air travel and provide an alternative to trucking freight. 

Environmentalists also have opposed the project, suing and claiming the construction project would harm 11 endangered species and worsen air quality in the already dirty Central Valley. They lost when a federal judge ruled the project did not have to adhere to the state Environmental Quality Act, unlike other projects. Additional legal challenges remain, but supporters believe once the train leaves the station and ground is broken, there's no going back. 

"The legacy of the Brown family is that they have been big thinkers, but also big builders," said Democratic state Assemblyman Henry Perea. "I think this is an opportunity for the legislature to step up, support Governor Brown. "

Volunteers Sought for Christmas Bird Count





Excerpt from
yourdailyjournal.com 


ROCKINGHAM — The National Audubon Society is inviting Richmond County birdwatchers to participate in the longest-running citizen science survey in the world, the annual Audubon Christmas Bird Count.

Beginning Sunday, hundreds of birders and nature enthusiasts across North Carolina will take part in this long-standing tradition where data collected has helped to shape influential conservation efforts nationwide.

As North Carolina’s landscape continues to evolve with changes... the data collected during the annual Christmas Bird Count is crucial to understanding the health of native and migrating bird populations throughout North Carolina. During the 2013 CBC, five snowy owls were spotted from Asheville to Wilmington, and local citizen scientists were on hand to detail the rare event.

North Carolina’s birding circles are some of the top performing in the country, and last year, a record 51 counts across the state reported 1,113,012 individual birds from 225 species.

“In a state where inspiring conservation action is vital to the health of birds facing the damaging effects of climate change, Audubon North Carolina is excited to be a leader in statewide conservation efforts,” Executive Director Heather Hahn said in a release. “As climate change continues to affect populations of the brown-headed nuthatch, American oystercatcher, wood thrush and many more iconic species, the data collected during this annual event becomes even more important to ongoing efforts to protect our birds.”

Each year, the Audubon Christmas Bird Count mobilizes more than 70,000 volunteer bird counters in more than 2,400 locations across the Western Hemisphere. The Audubon Christmas Bird Count utilizes the power of volunteers to track the health of bird populations at a scale that professional scientists could never accomplish alone. Data compiled across North Carolina will record every individual bird and bird species seen in a specified area, contributing to a vast citizen science network that continues a tradition stretching back more than 100 years.

Birders of all ages are welcome to contribute to this fun winter tradition and nationwide citizen science project, which provides ornithologists with a crucial snapshot of native bird populations during the winter months. Each individual count is performed in a count circle with a diameter of 15 miles.

At least 10 volunteers, including a compiler to coordinate the process, count in each circle. The volunteers break up into small parties and follow assigned routes, which change little from year to year, counting every bird they see. In most count circles, some people also watch feeders instead of following routes.

Gas falling under $3 per gallon nationwide







NEW YORK (AP) — The sight is so surprising that Americans are sharing photos of it, along with all those cute Halloween costumes, sweeping vistas and special meals: The gas station sign, with a price under $3 a gallon.
"It's stunning what's happening here," says Tom Kloza, chief oil analyst at the Oil Price Information Service. "I'm a little bit shocked."
The national average price of gasoline has fallen 33 cents in October, landing Friday at $3.00, according to AAA. Kloza said the average will fall under $3 by early Saturday morning for the first time in four years.
When the national average crossed above $3 a gallon in December of 2010, drivers weren't sure they'd ever see $2.99 again. Global demand for oil and gasoline was rising as people in developing countries bought cars by the tens of millions and turmoil was brewing in the oil-rich Middle East.
Now demand isn't rising as fast as expected, drillers have learned to tap vast new sources of oil, particularly in the U.S., and crude continues to flow out of the Middle East.
Seasonal swings and other factors will likely send gas back over $3 sooner than drivers would like, but the U.S. is on track for the lowest annual average since 2010 — and the 2015 average is expected to be lower even still.
Trisha Pena of Hermitage, Tenn., recently paid $2.57 a gallon to fill up her Honda CRV. Like many around the country these days, she was so surprised and delighted by the price she took a photo and posted it on social media for her friends to see. "I can't remember the last time it cost under $30 to put 10 or 11 gallons in my tank," she said in an interview. "A month ago it was in the $3.50 range, and that's where it had been for a very long time."
Here are a few things to know about cheap gas:
— Crude prices came off the boil. Oil fell from $107 a barrel in June to near $81 because there's a lot of supply and weak demand. U.S. output has increased 70 percent since 2008, and supplies from Iraq and Canada have also increased. At the same time, demand is weaker than expected because of a sluggish global economy.
— In the past, a stronger economy in the U.S., the world's biggest consumer of oil and gasoline, typically meant rising fuel demand. No longer. Americans are driving more efficient vehicles and our driving habits are changing. Michael Sivak of the University of Michigan Transportation Research Institute calculates that the number of miles traveled per household and gallons of fuel consumed per household peaked in 2004.
— The drop from last year's average of $3.51 per gallon will save the typical U.S. household about $50 a month.
— The drop will save the U.S. economy $187 million a day, and also boost the profits of shippers, airlines, and any company that sends employees out on sales calls or for deliveries.
— It will take an extra 1.5 years to make purchasing a higher-priced, better-mileage Toyota Prius instead of a Toyota Corolla pay off.
— New York's average of $3.37 is the highest in the continental U.S. South Carolina and Tennessee are the lowest, with an average of $2.75.
— Politicians are either going to take the credit for lower gasoline prices or blame the other party for not helping them fall further. Don't listen. There are small things politicians can do over long time horizons, like implement fuel economy standards or ease drilling regulations, but the decline in prices is mainly due to market forces.
