Sea Levels Could Rise At Least 20 Feet - (July 10, 2015 - by Brian Kahn - Climate Central) - Even if world manages to limit global warming to 2°C — the target number for current climate negotiations — sea levels may still rise at least 6 meters (20 feet) above their current heights, radically reshaping the world’s coastline and affecting millions in the process.
That finding comes from a new paper published on Thursday in Science that shows how high sea levels rose the last time carbon dioxide levels were this high.
The study examined past changes and laid out a framework for using them to refine our understanding of what the future holds for coastal communities. According to separate research by Climate Central, a 20-foot sea level rise would reshape the U.S. coast, causing Louisiana to lose its boot and transforming the Bay Area into the Bays Area by forming a second inland bay. It would also threaten the world's coastal nations and megacities.
The big outstanding question — and the one that’s most relevant to people living along the coasts — is just how long it could take sea levels to rise to such great heights. The process isn’t linear. It’s currently accelerating and that trend is expected to continue. [Andrea] Dutton [a geochemist at the University of Florida and one of the study’s co-authors] said her group is working on new techniques to better define the rates of rise, but other efforts have shown tipping points could cause sudden, rapid rises faster than previous estimates.
“There are some recent modeling efforts that now show you could get a section of the Antarctic ice sheet, several meters worth of sea level rise, to go in a decade. We used to think it was centuries,” she said. - http://tinyurl.com/nbpt8zf
Paradoxical Crystal Baffles Physicists - (July 2, 2015 - by Natalie Wolchover - Quanta Magazine) - At super-low temperatures, a crystal called samarium hexaboride behaves in an unexplained, imagination-stretching way.
In a deceptively drab black crystal, physicists have stumbled upon a baffling behavior, one that appears to blur the line between the properties of metals, in which electrons flow freely, and those of insulators, in which electrons are effectively stuck in place. The crystal exhibits hallmarks of both simultaneously.
“This is a big shock,” said Suchitra Sebastian, a condensed matter physicist at the University of Cambridge whose findings appeared today in an advance online edition of the journal Science. Insulators and metals are essentially opposites, she said. “But somehow, it’s a material that’s both. It’s contrary to everything that we know.” - http://tinyurl.com/qhwdmxj

Quantum networks: Back and forth are not equal distances - (July 27, 2015 - University of Copenhagen / Niels Bohr Institute - Science Daily) - Quantum technology based on light (photons) has great potential for radically new information technology based on photonic circuits. Up to now, the photons in quantum photonic circuits have behaved in the same way whether they moved forward or backward in a photonic channel. This has limited the ability to control the photons and thus build complex circuits for photonic quantum computers. Now researchers from the Niels Bohr Institute have discovered a new type of photonic channels, where back and forth are not equal distances! Such a system has been a missing component for building quantum photonic circuits on a large scale. The results are published in the scientific journal, Nature Nanotechnology. - http://tinyurl.com/ngync5h
to Coastlines: New Study Warns of Disastrous Sea Level Rise Within
Decades - (July 28,
2015 - By James Hansen / Huffington Post) - A new study
finds that an increase of 2 degrees Celsius, rather than being a safe
"guardrail" against the worst climate change effects, is actually
My conclusion, based on the total information available, is that continued high emissions would result in multi-meter sea level rise this century and lock in continued ice sheet disintegration such that building cities or rebuilding cities on coast lines would become foolish.
A startling conclusion of our paper is that effects of freshwater release onto the Southern Ocean and North Atlantic are already underway....
Here, I expand on our conclusion that the science indicates 2°C is not a safe target. Indeed, 2°C is not only a wrong target, temperature is a flawed metric due to meltwater effect on temperature. Sea level, a critical metric for humanity, is at least on the same plane. Earth's energy imbalance is a critical metric, because energy balance must be restored to stabilize climate, which thus informs us about the required limit on greenhouse gases (GHGs). The Framework Convention on Climate Change, agreed upon at Rio in 1992, defines GHGs as the critical metric, saying that GHGs must be stabilized at a level that avoids "dangerous anthropogenic interference" with climate. Why have policymakers turned away from GHG amount to temperature as the metric with a value (2°C) seemingly pulled from a hat? Could it be because 2°C allows politicians to set emission targets to be achieved in the future when they will be out of office? If we stick to the Framework Convention's GHG metric, we find that the CO2 stabilization level is not 450 ppm or 400 ppm, it is 350 ppm and possibly lower with immediate implications for policy.
The bottom line message scientists should deliver to policymakers is that we have a global crisis, an emergency that calls for global cooperation to reduce emissions as rapidly as practical. We conclude elsewhere and reaffirm in our present paper that the crisis calls for an across-the-board rising carbon fee and international technical cooperation in carbon-free technologies. - http://tinyurl.com/qe2q6rs
'Impossible' rocket drive works and could get to Moon in four hours - (July 28, 2015 - by By Sarah Knapton, Science Editor - The Telegraph/UK) - Interplanetary travel could be a step closer after scientists confirmed that an electromagnetic propulsion drive, which is fast enough to get to the Moon in four hours, actually works.
The EM Drive was developed by the British inventor Roger Shawyer nearly 15 years ago but was ridiculed at the time as being scientifically impossible.
It produces thrust by using solar power to generate multiple microwaves that move back and forth in an enclosed chamber. This means that until something fails or wears down, theoretically the engine could keep running forever without the need for rocket fuel. - http://tinyurl.com/puruqnw

Lightning Reshapes Rocks At The Atomic Level - (August 5, 2015 - University of Pennsylvania - ScienceDaily) - At a rock outcropping in southern France, a jagged fracture runs along the granite. [See photo.] The surface in and around the crevice is discolored black, as if wet or covered in algae. But, according to a new paper coauthored by the University of Pennsylvania's Reto Gieré, the real explanation for the rock's unusual features is more dramatic: a powerful bolt of lightning.
Another takeaway for geologists, rock climbers and hikers who spend time on rocks in high, exposed places is to beware when they see the tell-tale shiny black glaze of a rock fulgurite, as it might indicate a site prone to lightning strikes.

Bill Gates: The Private Sector Is Inept - (October 27, 2015 - by Janet Allon - AlterNet) - Bill Gates, still the world's richest man after all these years, does not have a lot of faith in his fellow billionaires or even capitalism when it comes to doing the right thing. It turns out he thinks the private sector is too selfish and inept to tackle the dire climate change situation, and relying on it would be courting disaster. Better to take a quasi socialist approach and remove the profit motive altogether from this important work.
In a wide-ranging interview with The Atlantic recently, Gates tacked pretty hard to the left. "There's no fortune to be made," he said, when it comes to developing clean energy sources and mitigating climate change. Besides, he pointed out, "the private sector is in general inept. How many companies do venture capitalists invest in that go poorly? By far most of them.”
“Since World War II, U.S.-government R&D has defined the state of the art in almost every area,” Gates told the Atlantic. “When I first got into this I thought, ‘How well does the Department of Energy spend its R&D budget?’ And I was worried: ‘Gosh, if I’m going to be saying it should double its budget, if it turns out it’s not very well spent, how am I going to feel about that? But as I’ve really dug into it, the DARPA money is very well spent, and the basic-science money is very well spent. The government has these ‘Centers of Excellence.’ They should have twice as many of those things, and those things should get about four times as much money as they do.” - http://tinyurl.com/ppmypng

Low-oxygen 'dead zones' in North Pacific linked to past ocean-warming events - (November 18, 2015 - Oregon State University - ScienceDaily) - A new study has found a link between abrupt ocean warming at the end of the last ice age and the sudden onset of low-oxygen, or hypoxic conditions that led to vast marine dead zones.
Large-scale warming events about 14,700 and again 11,500 years ago occurred rapidly and triggered loss of oxygen in the North Pacific, raising concern that low-oxygen areas will expand again as the ocean warms in the future. Anomalous warmth occurring recently in the Northeastern Pacific Ocean and the Bering Sea -- dubbed "The Blob" -- is of a scale similar to the events documented in the geologic record, the researchers say. If such warming is sustained, oxygen loss becomes more likely.
…the new study found a clear connection between two prehistoric intervals of abrupt ocean warming that ended the last ice age with an increase in the flux of marine plankton sinking to the seafloor, ultimately leading to a sudden onset of low-oxygen conditions, or hypoxia.
"During each warming event, the transition to hypoxia occurred abruptly and persisted for about 1,000 years, suggesting a feedback that sustained or amplified hypoxia." [lead author Summer] Praetorius added. - http://tinyurl.com/ol3yvct

Building Living, Breathing Supercomputers - (February 26, 2016 - McGill University - ScienceDaily) - The substance that provides energy to all the cells in our bodies, Adenosine triphosphate (ATP), may also be able to power the next generation of supercomputers. The discovery opens doors to the creation of biological supercomputers that are about the size of a book. That is what an international team of researchers led by Prof. Nicolau, the Chair of the Department of Bioengineering at McGill, believe. They've published an article on the subject earlier this week in the Proceedings of the National Academy of Sciences (PNAS), in which they describe a model of a biological computer that they have created that is able to process information very quickly and accurately using parallel networks in the same way that massive electronic super computers do.Except that the model bio supercomputer they have created is a whole lot smaller than current supercomputers, uses much less energy, and uses proteins present in all living cells to function. - http://tinyurl.com/jkbdznd

Hypervision: The Untold Story Of Magic Leap, The World’s Most Secretive Startup - (May 2016 - By Kevin Kelly - Wired Magazine) - Very soon, perhaps in five years, the bounded worlds within virtual reality will begin to be networked together into distributed virtual worlds.
…. Don’t let the relatively portable size of VR and MR wearables fool you. As they get smaller and lighter (and they will), the infrastructure behind them must grow larger and larger. The scale of the servers, bandwidth, processing, storage, and cleverness required to run networked virtual places at the scale of the planet for billions of people is beyond Big Data. It is Ginormous Data.
Which raises another issue. One of the underappreciated aspects of synthetic reality is that every virtual world is potentially a total surveillance state. By definition, everything inside a VR or MR world is tracked. After all, the more precisely and comprehensively your body and your behavior are tracked, the better your experience will be.
This comprehensive tracking of your behavior inside these worlds could be used to sell you things, to redirect your attention, to compile a history of your interests, to persuade you subliminally, to quantify your actions for self-improvement, to personalize the next scene, and so on. If a smartphone is a surveillance device we voluntarily carry in our pocket, then VR will be a total surveillance state we voluntarily enter.
[….]It’s very easy to imagine a company that succeeds in dominating the VR universe quickly stockpiling intimate data on not just what you and 3 billion other people favorite but what you do on weekends, what people you pay attention to, what scares you, where you go when you’re tired, how you greet strangers, whether you’re depressed, and a thousand other details. To do that in real life would be expensive and intrusive. To do that in VR will be invisible and cheap. - http://tinyurl.com/hsg64qs
