    Let's call this what it is. Post hoc rationalisation of error. They do not "understand" anything.

    If it happened, even to the lesser extent, then it should be dealt with. But, what does that have to do with the use of solar power? And how does it compare to, say, as one example, the rip off of the public that has been ongoing for years and amounts to hundreds of billions in the damage to landscapes and environment by coal companies. Damage that is for the public to pay for cleanup.
    Storage eh? 4 Gwh of storage.

    It seems you have the proof that this magic lunar power was all above board. Please provide it.

    Bats versus wind turbines.

    August 13, 2014

    Forschungsverbund Berlin e.V. (FVB)

    Wind turbines are responsible for the death of numerous bats. In a recent study, scientists determined the origin of these animals: they do not only come from local areas but many had been already on a long migratory journey. Who then bears responsibility not only for the protection of native bat populations, but also for the populations from other countries, a European study asks.

    Wind turbines are responsible for the death of numerous bats. In a recent study, scientists determined the origin of these animals: they do not only come from local areas but many had been already on a long migratory journey. Germany therefore bears responsibility not only for the protection of native bat populations, but also for the populations from other countries.

    Wind turbines are an important component of renewable energy policies. The technology is well advanced and wind is available in abundance, particularly in northern Germany. Although the problem of transporting the electricity to the power demanding southern parts of Germany is often discussed and the aesthetics of turbines commented upon, there is another problem: the rotor blades are a deadly danger for many birds and bats. Approximately 300,000 bats are estimated to be at risk of getting killed by German wind turbines every year, unless this risk is reduced by turning off the systems at night during the main activity hours of bats.

    In a recent study, published in the scientific journal PLOS ONE, a research team led by the Leibniz Institute for Zoo and Wildlife Research (IZW) identified the origin of greater noctules -- a migrating bat species that is often in collisions with wind turbines in the eastern states of Germany. More than one quarter of studied bats were not local but were on their way to their wintering grounds in Germany or southwestern Europe. They had started their flights in the northeastern range of the species in the Baltic States, Russia, Belarus or Poland.

    A surprisingly large proportion of females and young animals were amongst those killed. This is especially critical for wildlife populations, because with each female their potential offspring is also missing. Bat scientist Christian Voigt from the IZW in Berlin emphasizes: "The study shows that Germany bears responsibility not only for the protection of local bats, but also for the migrating bats from other countries owing to its central location as a transit area." Germany lies exactly on the migration route of bats, which move to warmer regions -- such as southern Germany, Switzerland or southern France -- during autumn after they left their breeding areas in northeastern Europe, where females give birth to their young every spring. Additional losses of bats at German wind turbines are particularly dramatic for these populations since unfavorable climatic conditions in their northern breeding range prevent them from successfully reproducing each year. If many of these bats die at German wind turbines, source populations in Northeastern Europe may get significantly weakened.

    The method by which the researchers determined the origin of bats comes from forensic science. When a cadaver of unknown origin appears, forensic experts examine the ratio of heavy to light hydrogen in the keratin of hair -- a "geographic fingerprint." This ratio varies in the precipitation water in relation to continental gradients of ambient temperature, i.e. precipitation in northern areas are less enriched in deuterium than that of southern areas. Humans and animals assimilate this water directly or through their food and deposit the isotopes in their body tissue. Since keratin is biologically inactive, the isotopic ratio remains constant over several months. As a geographical fingerprint it indicates the origin of a human or an animal. The method is so useful because the scientists can determine the origin of each bat without having to ring them, as is usually the case in conventional migration studies. That would truly require an immense effort.

    Unfortunately, wind turbines even attract bats. During the mating season in autumn, bats swarm at conspicuous landscape features such as exposed rocks, church towers or even wind turbines, and in the latter case they may then collide with the blades. Christian Voigt is surprised that only few far-reaching measures have been taken that stop wind turbines to turn into deadly traps: "Bats are protected under both national law and EU law, and migratory species are protected by a UN convention signed by Germany. Anyone who kills a bat on purpose can be prosecuted for a criminal offence." There is little emphasis on making operators of wind turbines accountable for these bat accidents because increasing the share of renewable energy is a political priority. "The protection of climate and species are played off against each other -- but for a comprehensive approach to environmental conservation they should really go hand in hand."

    Wind turbines and bats could actually get along well with each other: bats do not like strong wind. They are only active at wind speeds of up to six to eight meters per second. At this speed, wind turbines only just start to produce energy in an economic manner. If the turbines run only in strong wind, collisions could be avoided -- as could be those between the protectors of species and climate.

    Rays from solar-power plant ignite birds in midair | The Columbus Dispatch

    IVANPAH DRY LAKE, Calif. — Workers at a state-of-the-art solar plant in the Mojave Desert have a name for birds that fly through the plant’s concentrated sun rays — “streamers,” for the smoke plume that comes from birds igniting in midair.
    Federal wildlife investigators visited the BrightSource Energy plant last year and watched as birds burned and fell, reporting an average of one “streamer” every two minutes. They are urging California officials to halt the operator’s application to build a still-bigger version.


    The investigators want to assess the full extent of the bird deaths. Estimates per year now range from a low of about 1,000 by BrightSource to 28,000 by an expert for the Center for Biological Diversity environmental group.

    The deaths are “alarming. It’s hard to say whether that’s the location or the technology,” said Garry George, renewable-energy director for the California chapter of the Audubon Society. “There needs to be some caution.”

    The bird kills mark the latest instance in which the quest for clean energy sometimes has inadvertent environmental harm. Solar farms have been criticized for their impacts on desert tortoises, and wind farms have killed birds, including numerous raptors.
    “We take this issue very seriously,” said Jeff Holland, a spokesman for NRG Solar of Carlsbad, Calif., the second of the three companies behind the plant. The third, Google, deferred comment to its partners.

    The $2.2 billion plant, which launched in February, is at Ivanpah Dry Lake near the California-Nevada border. The operator says it’s the world’s biggest plant to employ so-called power towers.

    More than 300,000 mirrors, each the size of a garage door, reflect solar rays onto three boiler towers rising 40 stories high. The water inside is heated to produce steam, which turns turbines that generate enough electricity for 140,000 homes.
    Sun rays sent up by the field of mirrors are bright enough to dazzle pilots flying in and out of Las Vegas and Los Angeles.

    Federal wildlife officials said Ivanpah might act as a “mega-trap” for wildlife, with the bright light of the plant attracting insects, which in turn attract insect-eating birds that fly to their death in the intensely focused light rays.

    U.S. Fish and Wildlife officials say they want a death toll for a full year of operation.
    Given the apparent scale of bird deaths at Ivanpah, authorities should thoroughly track bird kills there for a year, including during annual migratory seasons, before granting any more permits for that kind of solar technology, said George, of the Audubon Society.

    The commission is now considering the application from Oakland-based BrightSource to build a mirror field and a 75-story power tower that would reach above the sand dunes and creek washes between Joshua Tree National Park and the California-Arizona border.

    The proposed plant is on a flight path for birds between the Colorado River and California’s largest lake, the Salton Sea — an area that experts say is richer in avian life than the Ivanpah plant, with protected golden eagles and peregrine falcons and more than 100 other species of birds recorded there.

    BOM finally explains! Cooling changed to warming trends because stations “might” have moved! « JoNova

    It’s the news you’ve been waiting years to hear! Finally we find out the exact details of why the BOM changed two of their best long term sites from cooling trends to warming trends. The massive inexplicable adjustments like these have been discussed on blogs for years. But it was only when Graham Lloyd advised the BOM he would be reporting on this that they finally found time to write three paragraphs on specific stations.
    Who knew it would be so hard to get answers. We put in a Senate request for an audit of the BOM datasets in 2011. Ken Stewart, Geoff Sherrington, Des Moore, Bill Johnston, and Jennifer Marohasy have also separately been asking the BOM for details about adjustments on specific BOM sites. (I bet Warwick Hughes has too). The BOM has ignored or circumvented all these, refusing to explain why individual stations were adjusted in detail.

    The two provocative articles Lloyd put together last week were Heat is on over weather bureau and Bureau of Meteorology ‘altering climate figures, which I covered here. This is the power of the press at its best. The absence of articles like these, is why I have said the media IS the problem — as long as the media ignore the BOM failure to supply their full methods and reasons the BOM mostly get away with it. It’s an excellent development The Australian is starting to hold the BOM to account. (No sign of curiosity or investigation at the ABC and Fairfax, who are happy to parrot BOM press releases unquestioned like sacred scripts.)

    Graham Lloyd sent the BOM a draft of his feature article for The Australian last Tuesday or Wednesday. The BOM finally replied at 5.30pm on Friday night as the last draft was almost ready to print. I’ve copied the whole BOM response here. I explain below why this is a good response for skeptics.

    The BOM rely on the usual vague wordy explanation with the unscientific reasoning that homogenization is necessary according to “international literature”. (I guess there is a consensus then, and we all know what that’s worth.) It is the scientific equivalent of saying “we’re experts — trust us”. No one would accept that from a company accountant, why from a sci
    entist?
