Climate Change's Inherent Uncertainties — Quadrant Online -
Climate Change's Inherent Uncertainties — Quadrant Online
Virtually all the scientists directly involved in climate prediction are aware of the enormous problems and uncertainties still associated with their product. How then is it that those of them involved in the latest report of the Intergovernmental Panel on Climate Change (IPCC) can put their hands on their hearts and maintain there is a 95 per cent probability that human emissions of carbon dioxide have caused most of the global warming that has occurred over the last several decades? Bear in mind that the representation of clouds in climate models (and of water vapour, which is intimately involved with cloud formation) is such as to amplify the forecast warming from increasing atmospheric carbon dioxide—on average over most of the models—by a factor of about three. In other words, two-thirds of the forecast rise in temperature derives from this particular model characteristic. Despite what the models are telling us—and perhaps because it is models that are telling us—no scientist... more... - Eric Logan from Bookmarklet
Bear in mind too that no scientist close to the problem and in his right mind, when asked the specific question, would say there is only a very small possibility (that is, less than 5 per cent) that internal ocean behaviour could be a major cause of the warming over the past half-century. He would be particularly careful not to make such a statement now that there has been no... more... - Eric Logan

OK. Got your attention. ;-) Paltridge makes the point at the end of his first 'Bear in mind' paragraph not copied here, "If he [climate scientist] is not sure that clouds amplify global warming, he cannot be sure that most of the global warming is a result of increasing carbon dioxide." Lock and load. These are model shortcomings. - MRW_8

How FDA and 23andMe Dance Around Evidence That Is Not There -
On July 20, 2010, Andrew Alexander, founder and director of easyDNA, received a letter from the US Food and Drug Administration. The FDA had noticed that easyDNA was marketing the "Genetic Predisposition Health Test, a home-use device that is intended to allow individuals to discover whether they are genetically predisposed towards developing a number of diseases and medical conditions, including cardiovascular conditions, different types of cancers, disorders of the immune system, diabetes as well as medical conditions related to ageing," a test that the FDA had not approved. - Halil from Bookmarklet
Less than four years later, and without much discussion in public, almost all of the 17 companies have stopped selling personal genome tests: some have completely exited the business, others are selling other tests or have matured into successful biotech companies. But two of them are still in business. - Halil

The Big Question in the climate change debate, as traditionally and conventionally posed, is: “is global warming caused by humans?” To those of us who know a little about climate science, it’s clearly an over-simplification, since climate scientists typically consider both anthropogenic and natural factors as part of the equation. The IPCC version of the Big Question is “is more than half of global warming caused by humans?” In the IPCC universe, the quest for the answer to the Big Question is known as attribution. Even though it’s not really black and white, the big question is used as if it is, and determines who you are. Are you a “warmist” or a “skeptic”? To be properly pigeonholed, you must answer the Big Question. And to answer it, you must understand it. That, however, may not be as easy as it seems. - Eric Logan from Bookmarklet

UK Parliamentary Hearing on the IPCC | Climate Etc. -
UK Parliamentary Hearing on the IPCC | Climate Etc.
A fascinating hearing on the IPCC was held today by the UK Parliament Energy and Climate Climate Change Committee. The link to hearing video is [here]. The witnesses: Professor Sir Brian Hoskins, Grantham Institute, Imperial College London, Professor Myles Allen, University of Oxford University, and Dr Peter Stott, Met Office Professor Richard Lindzen, Massachusetts Institute of Technology, Nicholas Lewis, Climate researcher, and Donna Laframboise, Author I listened to the entire hearing this morning, I really didn’t have 3 hours to spare in today’s schedule, but I couldn’t resist. It was definitely worth listening to. A quick reaction to the form (rather than the substance). I found this format to be much more illuminating and informative than the typical Congressional hearing in the U.S., where the members posture and pontificate and try to catch out the witnesses with ‘gotcha’ questions. By contrast the UK MP’s had really done their homework and asked very good questions, with a minimum of ‘gotcha’ type questions. - Eric Logan from Bookmarklet

Polar drilling problems revealed - Nature News.
Over the past year, researchers, engineers and officials involved in the US$12-million drilling project, funded by the UK Natural Environment Research Council, have carried out and responded to several internal reviews into the reasons for its failure. And now, in a paper under review by the Annals of Glaciology, Siegert, who is based at the University of Bristol, UK, and his colleagues have summarized the problems that they suffered at Lake Ellsworth and laid out options for putting them right. They think that several years of engineering work will be required to develop improved technology for a more reliable drill, but they say that success is achievable. “I am glad to see that they plan to publish their drilling efforts,” says John Priscu, a glaciologist at Montana State University in Bozeman who has worked on similar lake-drilling projects in western Antarctica. “It will quell rumours and provide a solid bit of groundwork on which they can move forward.” Lake Ellsworth is one of... more... - Eric Logan from Bookmarklet

The case of the missing heat | Climate Etc.
Now, no one understands the cause of the pause, but climate scientists say the heat is hiding in the ocean. My next post will be on ocean heat content, so I’m not getting into this here. The competing explanation (the ‘denier’ one, I guess since I don’t hear mainstream climate scientists mentioning this) is that the heat never made it into the system, possibly related to changing cloud patterns or properties that reflected more solar radiation. - Eric Logan from Bookmarklet

It's solar max! Stare at the sun for 30 minutes, online, right here - -
The show will revolve around a massive dark spot on the sun known as solar spot AR 1944. Last week, a massive X-class solar flare erupted from this area, causing enormous amounts of solar material to come hurtling toward Earth. Concern about the resulting increase in radiation in near-space led engineers at Orbital Sciences Corp. to delay the launch of a rocket scheduled to carry supplies to the International Space Station on Jan. 8. Solar spot AR 1944 was about 10 times the diameter of Earth when it first rotated into sight on Jan. 1. Slooh astronomers note that some smaller spots have appeared in the sun spot's wake.

Senate EPW Hearing on the President’s Climate Action Plan | Climate Etc. -
Senate EPW Hearing on the President’s Climate Action Plan | Climate Etc.
The premise of the President’s Climate Action Plan is that there is an overwhelming judgment of science that anthropogenic global warming is already producing devastating impacts. Anthropogenic greenhouse warming is a theory whose basic mechanism is well understood, but whose magnitude is highly uncertain. Multiple lines of evidence presented in the recent IPCC 5th assessment report suggest that the case for anthropogenic warming is now weaker than in 2007, when the 4th assessment report was published. My written testimony documented the following evidence: For the past 16 years, there has been no significant increase in surface temperature. There is a growing discrepancy between observations and climate model projections. Observations since 2011 have fallen below the 90% envelope of climate model projections The IPCC does not have a convincing or confident explanation for this hiatus in warming. There is growing evidence of decreased climate sensitivity to atmospheric carbon... more... - Eric Logan from Bookmarklet

Climate change: The case of the missing heat : Nature -
Climate change: The case of the missing heat : Nature
Researchers have followed various leads in recent years, focusing mainly on a trio of factors: the Sun1, atmospheric aerosol particles2 and the oceans3. The output of energy from the Sun tends to wax and wane on an 11-year cycle, but the Sun entered a prolonged lull around the turn of the millennium. The natural 11-year cycle is currently approaching its peak, but thus far it has been the weakest solar maximum in a century. This could help to explain both the hiatus and the discrepancy in the model simulations, which include a higher solar output than Earth has experienced since 2000. An unexpected increase in the number of stratospheric aerosol particles could be another factor keeping Earth cooler than predicted. These particles reflect sunlight back into space, and scientists suspect that small volcanoes — and perhaps even industrialization in China — could have pumped extra aerosols into the stratosphere during the past 16 years, depressing global temperatures. Some have argued... more... - Eric Logan from Bookmarklet

Scientists discover giant trench under Antarctic Ice
Professor Martin Siegert, Professor of Geosciences at the University of Bristol, said: "While the idea of West Antarctic Ice Sheet growth and decay over the past few million years has been discussed for decades, the precise location where the ice sheet may originate from in growth phases, and decay back to in periods of decay, has not been known. "By looking at the topography beneath the ice sheet using a combination of ice-penetrating radio-echo sounding and satellite imagery, we have revealed a region which possesses classic glacial geomorphic landforms, such as u-shaped valleys and cirques, that could only have been formed by a small ice cap, similar to those seen at present in the Canadian and Russian High Arctic. The region uncovered is, therefore, the site of ice sheet genesis in West Antarctica."

Unprecedented High Levels of Molecular Chlorine Discovered in the Arctic Atmosphere -
Unprecedented High Levels of Molecular Chlorine Discovered in the Arctic Atmosphere
In order to measure the chlorine levels in the Arctic, the researchers used chemical ionization mass spectrometry over a six-week period in the spring of 2009. They then spent several years running other experiments to ensure their findings were accurate. So what did they find? It turns out that the level of molecular chlorine above Barrow was as high as 400 parts per trillion. That's a high concentration considering that chlorine atoms are short-lived in the atmosphere because they are strong oxidants and are highly reactive with other atmospheric chemicals. The concentrations of this molecular chlorine peaked in the early morning and late afternoon, and fell to near-zero levels at night. Average daytime molecular chlorine levels were correlated with ozone concentrations, suggesting that sunlight and ozone may be required for molecular chlorine formation. "Molecular chlorine is so reactive that it's going to have a very strong influence on atmospheric chemistry," said Huey in a news... more... - Eric Logan from Bookmarklet

Global Warming Pause Due To Pacific Says Trenberth
Global Warming Pause Due To Pacific Says Trenberth
“We can speculate that the huge 1997–1998 El Niño event was a trigger for the change in the PDO; certainly, it led to a large loss of heat in the Pacific... that has taken years to recover from, if the recovery is even complete. Past behavior of the PDO... suggests that regimes can last for 25 years,” Trenberth and Fasullo write in their paper. “The picture emerging is one where the positive phase of the PDO from 1976 to 1998 enhanced the surface warming somewhat by reducing the amount of heat sequestered by the deep ocean, while the negative phase of the PDO is one where more heat gets deposited at greater depths, contributing to the overall warming of the oceans but cooling the surface somewhat. The Pacific Ocean appears to account for the majority of the decadal variability... Nevertheless, the events in the Pacific undoubtedly also affect the Atlantic, Indian, and Southern Oceans as the system acts collectively to equilibrate to these changes in the flow of energy,” they write. The paper, entitled “An apparent hiatus in global warming?”, appears the new scientific journal Earth Futures. - Eric Logan from Bookmarklet

Is the Universe Made of Math? - Scientific American
What's the answer to the ultimate question of life, the universe, and everything? In Douglas Adams' science-fiction spoof “The Hitchhiker's Guide to the Galaxy”, the answer was found to be 42; the hardest part turned out to be finding the real question. I find it very appropriate that Douglas Adams joked about 42, because mathematics has played a striking role in our growing understanding of our Universe. The Higgs Boson was predicted with the same tool as the planet Neptune and the radio wave: with mathematics. Galileo famously stated that our Universe is a “grand book” written in the language of mathematics. So why does our universe seem so mathematical, and what does it mean? In my new book “Our Mathematical Universe”, I argue that it means that our universe isn’t just described by math, but that it is math in the sense that we’re all parts of a giant mathematical object, which in turn is part of a multiverse so huge that it makes the other multiverses debated in recent years seem puny in comparison. - Eric Logan from Bookmarklet

Gold on Earth formed in collision of exotic stars -
Gold on Earth formed in collision of exotic stars
Dying stars billions of years ago cooked up most of the lighter elements in the universe, the oxygen in the air and calcium of our bones, and blasted it across the cosmos in their final explosive moments. We are stardust, as the singer Joni Mitchell put it. But some of the heaviest atoms, including gold, defied this explanation, requiring an even more exotic origin. A team led by Harvard astronomer Edo Berger now reports that gold is likely created as an aftereffect of the collision of two "neutron" stars. Neutron stars are themselves the collapsed remains of imploded stars, incredibly dense stellar objects that weigh at least 1.4 times as much as the sun but which are thought to be less than 10 miles wide. While ordinary stars explode about once every century in our galaxy, Berger says, explosive collisions of two neutron stars happen only about once every 10,000 years. And it appears they spew out gold and other heavy elements in the week after their merger. - Eric Logan from Bookmarklet

Smallest, Faintest Galaxies of the Ancient Universe Spotted.
Two of NASA's most powerful space telescopes have teamed up to shed new light on the early history of the universe. The Hubble Space Telescope utilized a natural zoom lens to capture nearly 60 of the smallest, faintest galaxies ever spotted in the distant universe. In a separate study, observations by the Spitzer Space Telescope helped researchers determine the masses of four of the brightest early galaxies after Hubble picked them out. Both results could be followed up by NASA's James Webb Space Telescope, an $8.8 billion observatory slated to be launched in late 2018, officials said. - Eric Logan from Bookmarklet
The ash dieback fungus, Chalara fraxinea, might have a mechanism to define territory and to combat viruses, research shows #ashdieback -
Vegetative compatibility (vc) systems are a fungal equivalent of the tissue rejection systems in humans, enabling the fungus to distinguish between self and non-self. Fungal colonies of the same vc-type can fuse to form a single individual, but those of a different vc-type cannot. Vc systems are central to the ecology and survival of a fungus, enabling it to define its territory, to resist viral attack and to promote outbreeding. Initial results show that the vc system of C. fraxinea generates a reaction between incompatible colonies which makes their filaments (the mycelium) collapse, creating a zone between the two colonies where growth is inhibited. - Halil
Commenting on their results, Professor Brasier said: “This research is still at a preliminary stage. The fact that most isolates of Chalara fraxinea are incompatible with each other could mean that it might be difficult to deploy damaging fungal viruses against the pathogen as a disease control method, since viruses usually spread more readily in a fungal population when the colonies are able to fuse.” - Halil
Inhibition of Pseudogymnoascus destructans Growth from Conidia and Mycelial Extension by Bacterially Produced Volatile Organic Compounds. -
The recently identified causative agent of white-nose syndrome (WNS), Pseudogymnoascus destructans, has been implicated in the mortality of an estimated 5.5 million North American bats since its initial documentation in 2006 (Frick et al. in Science 329:679-682, 2010). In an effort to identify potential biological and chemical control options for WNS, 6 previously described bacterially produced volatile organic compounds (VOCs) were screened for anti-P. destructans activity. The compounds include decanal; 2-ethyl-1-hexanol; nonanal; benzothiazole; benzaldehyde; andN,N-dimethyloctylamine. P. destructans conidia and mycelial plugs were exposed to the VOCs in a closed air space at 15 and 4 °C and then evaluated for growth inhibition. All VOCs inhibited growth from conidia as well as inhibiting radial mycelial extension, with the greatest effect at 4 °C. Studies of the ecology of fungistatic soils and the natural abundance of the fungistatic VOCs present in these environments suggest a... more... - Halil from Bookmarklet

“It can basically live on any complex carbon source, which encompasses insects, undigested insect parts in guano, wood, dead fungi and cave fish,” Raudabaugh said. “We looked at all the different nitrogen sources and found that basically it can grow on all of them.

The treatment has, so far, only been shown to work in HIV-infected mice. Clinical trials would be needed to establish whether it could work in people. As it stands, there are no plans in place to fund a trial. The treatment would work by taking blood from infected patients, treating it with the enzyme, and transfusing it back into the patients. The enzyme targets stem cells, altering their DNA. Once reintroduced into the body, these cells would reproduce, and cut the HIV from other infected cells. Such results were seen in the mice. Professor Hauber said that 'the amount of virus was clearly reduced, and even no longer to be found in the blood.' - Halil from Bookmarklet

The first details of HIV's inner coat could hold clues for future drugs that may no longer target the virus, but instead will attack the protective shell that encases it. #HIV #AIDS #Cure -
The findings, published in the May 30 issue of Nature, take a closer look at the 4-million-atom structure of HIV's protein shell, also known as the capsid. "The capsid is critically important for HIV replication, so knowing its structure in detail could lead us to new drugs that can treat or prevent the infection," said Peijun Zhang, senior author of the study and associate professor in the department of structural biology at the University of Pittsburgh School of Medicine. "This approach has the potential to be a powerful alternative to our current HIV therapies, which work by targeting certain enzymes, but drug resistance is an enormous challenge due to the virus' high mutation rate." - Halil from Bookmarklet
"The capsid is very sensitive to mutation, so if we can disrupt those interfaces, we could interfere with capsid function," Zhang said. "The capsid has to remain intact to protect the HIV genome and get it into the human cell, but once inside it has to come apart to release its content so that the virus can replicate. Developing drugs that cause capsid dysfunction by preventing its assembly or disassembly might stop the virus from reproducing." - Halil
Sounds promising. But I still don't understand why we have such high rates of "new" infections in younger generations in countries like the US and the EU! for stats see - Halil

Alzheimer's-Causing Protein Could Be Nanomaterial of the Future - IEEE Spectrum
Researchers at Chalmers and Wroclaw University of Technology in Poland revealed last month how laser techniques aimed at the amyloid protein could help find a cure for not only Alzheimer’s, but also other brain diseases caused by the amyloid, such as Parkinson’s and Creutzfeldt-Jakob disease (known as Mad Cow disease). “Nobody has talked about using only light to treat these diseases until now,” says Piotr Hanczyc at Chalmers in a press release. “This is a totally new approach and we believe that this might become a breakthrough in the research of diseases such as Alzheimer’s, Parkinson’s and Creutzfeldt-Jakob disease. We have found a totally new way of discovering these structures using just laser light.” But beyond a treatment for these brain diseases, the researchers believe that it could have even more far afield applications in photonics an optoelectronics. The researchers believe that the ability to change the characteristics of a material that have been merged with the amyloid just by using multi-photon irradiation opens up some sci-fi capabilities for the material. - Eric Logan from Bookmarklet

Reddit has banned climate change deniers, and ripped its own reputation to shreds – Telegraph Blogs
Reddit, the massively popular links-sharing website where users post stories, pictures or info that they find interesting, prides itself on being open and liberal. It describes itself as “passionately dedicated to free speech”. In which case, why has it banned from its forums anyone who raises awkward or annoying questions about the science of climate change? In a move that has been described by one British academic as “positive censorship”, a Reddit moderator has announced that Reddit is becoming “increasingly stringent with deniers”. The Reddit moderator says climate “contrarians” were too often expressing “uninformed and outspoken opinions”, and so the site decided to adopt a much more “proactive moderation”. Now, whenever a user makes a “potentially controversial submission” on climate change, the moderators issue that user with a “warning”.

quote=SPIEGEL: Are there findings related to global warming that worry you? STORCH: The potential acidification of the oceans due to CO2 entering them from the atmosphere. This is a phenomenon that seems sinister to me, perhaps in part because I understand too little about it. But if marine animals are no longer able to form shells and skeletons well, it will affect nutrient cycles in the oceans. And that certainly makes me nervous. - Sean McBride
“NOAA deploys first buoy in region to monitor levels of CO2 absorbed by ocean” In the Arctic. August 2013. “The moored buoy is the first of its kind to be deployed north of the Arctic circle in a region where very little is known about how carbon dioxide (CO2) is entering the ocean environment." - MRW_8
They don’t even have the proper tools to measure acidification. The Wendy Schmidt [Eric Schmidt’s wife] Ocean Health X Prize was announcedin in September 2013 “$2 million in prizes offered for better tools to monitor ocean acidification.” Because they don’t know. Don’t have a clue. - MRW_8
The pH of the ocean is still alkaline. It has to be below 7.0 pH to be acidic. It’s currently at 8.1 or 8.2 (memory), and was either 8.2, or 8.3, 100 years ago. The pH scale is logarithmic, not linear, so a drop of 1 unit in pH equals a ten-fold increase in acidity. Anyone who says they can project the acidity in two decades, much less by 2100 AD, is full of shit, or mumbling for funding. - MRW_8
"The pH of the ocean is still alkaline. It has to be below 7.0 pH to be acidic." -- WTF? The point is that the pH is rapidly dropping ("acidification") not that it's already acidic and becoming more so. - Andrew C (✔)
Fossil records suggest strongly that acidification is occurring and it's altering ocean life: - Andrew C (✔)
Andrew, the discover magazine article links to the 2009 paper. The abstract of the paper clearly shows that they were doing lab work with shells and sedimentary fossils, with a lot of caveats and guesses about acidification. The lead author was William R Howard of Antarctic Climate and Ecosystems Cooperative Research Centre, Hobart, Tasmania. Their website (which I assume was update... more... - MRW_8
The director of Avatar and Titanic, Jim whatever, is an ocean buff. I remember when he went down to the Mariana Trench last year in the sub he invented. When he came up exhilarated, he remarked that the most we know about the oceans is 3% of what's there. - MRW_8
From the Argo buoy site: QUOTE. Lack of sustained observations of the atmosphere, oceans and land have hindered the development and validation of climate models. An example comes from a recent analysis which concluded that the currents transporting heat northwards in the Atlantic and influencing western European climate had weakened by 30% in the past decade. This result had to be based... more... - MRW_8
[article; TITLE Report finds CO2 causing rapid ocean acidification DATE December 13, 2013 AUTHOR Laura Sesana PERIODICAL Washington Times URL http://communities.washingtont...] - Sean McBride
[<; QUOTE A report released in November concludes that the world’s oceans are acidifying at an “unprecedented rate.” Authored by researchers at the 2012 Third Symposium on the Ocean in a High CO2 World, the report warns that oceans have become 26% more acidic since the beginning of the Industrial Revolution and continue to do so. PARAGRAPH Since the start of the Industrial Revolution, the world’s oceans have absorbed about a quarter of all CO2 emissions released by humans, according to the report.] - Sean McBride
[<; QUOTE “What I’m hoping is that people realize that CO2 is not just a question of global warming. That we are acidifying the ocean at a rate that has been unprecedented — for millions and millions of years,” said one of the report’s authors, Daniela Schmidt from the University of Bristol, to CNN. “The more CO2 emissions, the more acidification. The ocean is in direct interchange with the atmosphere.”] - Sean McBride
We may not possess absolute certainty about the science of global warming and acidification, but we know enough about the science to be highly concerned. The vast majority of people I have encountered who have tried to blow off that concern have been ignoramuses of the first order. Many of them are wacky conspiracy theorists who believe that all environmentalists are tools of the totalitarian New World Order -- Alex Jones fans. - Sean McBride
