Article: Scientists warn an entire eco-system is under threat from climate change

I am not doubting the connection between craneflies, bogs and rare birds. And that they are all threatened by increasing droughts.

However, I ran across a comment a few weeks ago about the tentativeness of predictions involving the effects of global warming (and, no, I refuse to use "climate change.")

So here are the "tentative" words, and some comments.
Warn; threat; climate change (actually global warming); are being put at risk; climate change; warn; climate change; [predicted] rising temperatures; climate change; predicted; will cause; peatland model; climate change; predictions; could see; securing the future; peatland model; climate change; climate change; risk; climate change; big change; change; climate change; climate change. 
The body of the article has about 694 words (WordPerfect), 22 sentences, 26 "tentatives" and 10 uses of "climate change."

The peatland model is based on climate models and accepts them as accurate, even though all of the climate models in the IPCC reports have not been falsified.


Article: Readiness of America's biology teachers questioned
Data spanning 1987 to 2007 show changing demographics among public high school biology teachers. The workforce has become less experienced and has been destabilized by turnover, and biology teachers are more likely than other science teachers to work outside of their discipline.
I do not have enough personal knowledge about this. However, I do know that of the 6 people who teach biology at my high school, none teach all biology all the time. Four of the 6 teach biology related courses, while 2 teach other sciences. 

Bold-faced is mine. 
The authors support alternatives to the typical calls for more stringent certification and targeted professional development. In their view, it would be better to match curricula to existing expertise. They propose a model in which "instead of offering a static, predetermined slate of science courses at each school, district, or county, the curriculum is chosen largely as a function of the expertise of those teachers who they employ." 
Currently, curriculum is "top down" and controlled at the state and federal levels.

Actually having biology teachers teach their areas of expertise is a throw back to a previous, and long gone era.
Article: Researchers just developed a revolutionary vaccine that offers '100% protection against Ebola'

Good news.
The test, backed by drug firm Merck, the WHO and the governments of Canada, Norway and Guinea, saw 4,123 high-risk people vaccinated immediately after someone close to them fell ill with the deadly haemorrhagic fever.  
None of the vaccinated group caught the virus, according to study results published in The Lancet medical journal.

Article: European Renewable Energy performance for 2014 falls far short of claims
By 2014 European Union countries had invested approximately €1 trillion, €1000,000,000,000, in large scale Renewable Energy installations. 
This has provided a nameplate electrical generating capacity of about 216 Gigawatts, nominally about ~22% of the total European generation needs of about 1000 Gigawatts.
The actual measured output by 2014 from data supplied by the Renewables Industry has been 38 Gigawatts or 3.8% of Europe’s electricity requirement, at a capacity factor of ~18% overall.
Contrast that with coal or gas power plants that can operate at close to 100% capacity.
Accounting for capacity factors the capital cost of these Renewable Energy installations has been about €29billion / Gigawatt.  That capital cost should be compared with conventional gas-fired electricity generation costing about €1billion / Gigawatt.
Renewables cost 29X as much to install as gas-fired plants.

The wealthy elite are gaga over renewables, but they can afford to spend a lot more for energy. Back when Al Gore was pushing his "documentary" it was revealed that his primary residence used more electricity in one month that the average American used in one year.
In spite of their [ed., "there"] being virtually no costs for fuel, Renewable Energy installations can still cost up to 1.5 – 2.5 times as much to operate and maintain as conventional Gas Fired plant.
And the effect is to increase the cost of renewables even more.
Accordingly German Renewable installations perform at only ~13% overall.  They are by far the least performant in Europe because of their heavy commitment to Solar Energy at Northern latitudes.  Germany is followed by Italy with a more Southerly position but still with a heavy commitment to Solar Power.
Low solar incidence angle and short days for 6 months of the year. Berlin, Germany is 52 degrees North. Northernmost Maine is 47 degrees North. How did any rational person think that solar energy was a good choice for Germany?
In France which already has the lowest CO2 emissions levels/head [ed., per capita] of population in the developed world (substantially less (~60%) than China) because of its commitment to Nuclear electrical generation, the installation of Renewable Energy (Wind Power and Solar) in France would seem to be particularly costly and pointless.
If governments want low CO2 emissions, they should go with nuclear.

If they want to kill poor people in the winter, so with renewables.
Conclusions 
To date about € trillion, (€1000,000,000,000), has been spent on the installation of Renewable Energy technologies for electricity generation in Europe.
By Government and EU diktat, this expenditure has been extracted by extra charges imposed on utility bills throughout Europe.  Viewed as taxation this is very regressive form:  it imposes more burdens on poorer people whilst leaving wealthier people who are able to pay less affected.  It is also invisible in Government accounts as a tax income at all, as it is an industry price imposition on consumers.
These regressive “Green taxes” have already lead to significant fuel poverty throughout Europe.
As I said, if they want to kill poor people in the winter, go with renewables.
The USA has made significant CO2 emissions reductions over the past few decades by replacing Coal Fired generation with Gas Fired electricity generation with the feedstock provided by the fracking revolution.  It is estimated that using natural gas for electricity generation as opposed coal burning saves about 30% of CO2 emissions.  
So the most environmentally sound, logical, rational, scientific, economic, compassionate choices are
1) Natural gas (and fracking).
2) Nuclear.

On the other hand renewables are the best choice for the elite because they offer
1) Smug moral superiority
2) Good opportunities for cronyism and graft.
It is also questionable whether these Renewable Energy industries, when viewed “from cradle to grave”, including manufacturing, site works, installation, connection and demolition costs, does in fact reduce CO2 emissions to any significant extent overall.  The CO2 saved may never exceed the CO2 emissions generated to erect the total installation.  
This is like the ethanol boondoggle in the US. Use lots of land and fossil fuels to grow and harvest corn, then lots of fossil fuels convert the corn to alcohol and purify it. Then claim that you are reducing CO2 emissions by using a "biofuel" from a renewable resource. All the while by driving up food (and fuel) costs by diverting corn (and land) from being a feedstock.

Article: Independent expert confirms that the "impossible" EM Drive actually works
As efficient as this type of propulsion may sound, it defies one of the fundamental concepts of physics - the conservation of momentum, which states that for something to be propelled forward, some kind of propellant needs to be pushed out in the opposite direction. 
For that reason, the drive was widely laughed at and ignored when it was invented by English researcher Roger Shawyer in the early 2000s. But a few years later, a team of Chinese scientists decided to build their own version, and to everyone's surprise, it actually worked. Then an American inventor did the same, and convinced NASA's Eagleworks Laboratories, headed up by Harold 'Sonny' White, to test it. 
The real excitement began when those Eagleworks researchers admitted back in March that, despite more than a year of trying to poke holes in the EM Drive, it just kept on working - even inside a vacuum.
It might turn out that we need to rewrite some of our laws of physics in order to explain how the drive works. But if that opens up the possibility of human travel throughout the Solar System - and, more importantly, beyond - then it's a sacrifice we're definitely willing to make. Bring on the next set of tests.
Article #2: Engineers demonstrate the world’s first white lasers
While lasers were invented in 1960 and are commonly used in many applications, one characteristic of the technology has proven unattainable. No one has been able to create a laser that beams white light. 
Researchers at Arizona State University have solved the puzzle. They have proven that semiconductor lasers are capable of emitting over the full visible color spectrum, which is necessary to produce a white laser.
Applications include replace standard lighting because lasers are more efficient in change electrical energy into visible light. More vivid display screens (computers and TVs). And communications.

The lasers are also "tunable".

So far, this is "proof of concept" and not yet practical.

Article #3: Astronauts find living organisms clinging to the International Space Station, and aren’t sure how they got there
During a spacewalk intended to clean the International Space Station, Russian astronauts took samples from the exterior of the station for a routine analysis. The results of the experiment were quite surprising. Astronauts expected to find nothing more than contaminants created by the engines of incoming and outgoing spacecraft, but instead found that living organisms were clinging to outside of the ISS. The astronauts identified the organisms as sea plankton that likely originated from Earth, but the team couldn’t find a concrete explanation as to how these organisms made it all the way up to the space station — or how they managed to survive.
The article leads with a photo of diatoms (phytoplankton), but says that the organisms are invertebrates.

Article #4: Scientists identify men who died at Virginia's Jamestown 400 years ago
The men were identified as the Reverend Robert Hunt, Captain Gabriel Archer, Sir Ferdinando Wainman and Captain William West. All of them helped guide the colony during its difficult years after its founding in 1607. 
Researchers used archaeology, skeletal analyses, chemical testing, 3-D technology and genealogical research to identify the men who lived and died when the settlement was on the brink of failure due to famine, disease and war.

This is post #300.

Allow me to congratulate myself. ;)

Article: The Colossal Hoax Of Organic Agriculture

Well, yes.

Points made:

  • The "organic" pesticides permitted are still toxic. 
  • There is a huge premium to buying organic (up to 100%)
  • Researchers found that “99.99 percent (by weight) of the pesticides in the American diet are chemicals that plants produce to defend themselves.”
  • Food certified organic may contain GMOs. 
  • "The organic community... opposes more frequent mandatory testing of organic products for prohibited and excluded substances."
  • It is "faith based" because food is certified as organic if the farmer follows the correct process, not if there are low amounts of pesticide residues in the food. 
  • It is "faith based" because farmers have an incentive to substitute cheaper non-organic food for more expensive to produce organic food. 
  • "Organic agriculture is an unscientific, heavily subsidized marketing gimmick..."

And:
Speaking of trust and faith—or lack thereof–in organic foods, there was the example of holier-than-thou Whole Foods importing large amounts of its supposedly “organic” produce from China, of all places. Those imports even included Whole Foods’ house brand, “California Blend.” (Yes, you read that correctly.)
I began reading the magazine, "Organic Gardening" while in my teens (early 1970's). One aunt and uncle also grew most of their garden organically and I talked with them a lot.

I grow my own garden organically, although I will use the classic herbicides on my lawn and gravel.

For me it is a choice. I police the garden for various types of caterpillars, and I hand weed. I let mildew take the cucumbers and daisies.

However, organic farming, and selling food as "organic" I always thought was a waste of money, with a large amount of "tribal value signalling."  "Look at me! I am virtuous; I buy organic. I support Mother Earth."

Additionally, the idea that organic agriculture should be the way to go instead of "non-organic" farming is an elitist view. People who can afford to pay premium prices should not impose that on others. Poor people benefit from cheap food. Period.

It is an actual example of the story falsely attributed to Marie Antoinette. When told that the bakers of Paris did not have enough bread for the poor, she is supposed to have reply, "Let them eat cake."

Organic methods simply not as productive on a per acre basis. This, by itself, both drives up prices and decreases the food supply.

"Let them organic," is not as resonant, but no less true.

I gave this a "moral panic" tag because of the fear of pesticides.
