Basit bir Google araştırması yaptık, durumu anladık. Asit yağmurlarıyla ilgili üç tür yayın var. Bir gurubu NASA'nın yaptığı bilimsel çalışmalarla ilgi. Bu çalışmalarda atmosferde artan karbondioksit seviyesinin yağan yağmurlarda pH'ı ne kadar azalttığı, bunun da denizlerde ve toprakta pH'ı ne kadar değiştirdiğiyle ilgili. Toprakta azalan pH topraktaki mikroorganizma florasını nasıl etkiliyor, bunun özellikle metan üreten bakteri populasyonuna etkisi nedir? Vs. vs. konu bu. Diğer gurup yayınlarda ise ki, işin palavra bölümü burada, özellikle Afrika'da, Nijerya da belirli günlerde asit yağmurlarının yağacağı, insanların asitle yanacağı, deri kanseri olacağı iddiaları var.

Acid Rain Warning HoaxOutlineMessage warns recipients that there is a possibility of dangerous acid rain falling between the 20th and 28th of the month as indicated by dark circles appearing around the moon. Brief Analysis This warning is utter nonsense and should not be taken seriously. Dark circles around the moon are not an indication of impending acid rain. The alert is not from NASA as claimed in the email. In fact, a NASA spokesperson has denied any connection between circles around the moon and acid rain. Forwarding this false warning will do nothing more than cause unnecessary fear and alarm. Detailed analysis and references below example. Scroll down to submit comments Subject: Fw: Acid rain alert Hi Be careful from the 20th to 28th of this month, There is possibility of an ACID RAIN. The dark circle appeared around the moon on 17th of last month and this is an indication of Acid Rain. Apparently this happens once in 750 years. It rains like normally but It may cause skin cancer if you expose yourself to it. So ALERT your dear ones. This information is from NASA. DO NOT neglect. Plz Forward this to your friends, Better to be cautious than sorry. Detailed Analysis This widely circulated message warns recipients that cancer-causing acid rain may fall between 20th and 28th of the month. The warning circulates via email, text message and social networking websites. The message claims that dark circles that were seen around the moon during the previous month were an indication of the impending acid rain event. According to the message, the warning was issued by US space agency NASA.
A Jet Propulsion Laboratory (JPL) expert with NASA, Bill Patzert in his response to an inquiry from THEWILL on Monday said a black or dark circle around the moon is a common occurrence in space and has no relationship whatsoever with acid rain. "Dark circles around the moon are more common than you realize. Basically it's an optical illusion when you get very clear skies and fine ice particle in the upper atmosphere. "What you get is the moon, a dark circle round it, then a sky lit up with diffracted moonlight. It looks pretty, that is all. Nothing mystical or paranormal at all,"he added.A prominent African scientist has also debunked the rumour. A March 24 2010 Business Day article notes: Joseph Akinyede, director, African Regional Centre for Space Science and Technology Education and Bill Patzert, a meteorologist at the National Aeronautics and Space Administration (NASA) on Tuesday allayed fears that current dust haze in the country may result to acid rain.Experts in Pakistan were also compelled to quell the rumour after the warning began causing alarm among Pakistani citizens. In an April 16 2010 article, Pakistani news outlet the Daily Times notes: Pakistan Meteorological Department (PMD) Director General Dr Qamaruz Zaman Chaudhry on Thursday refuted the rumours about ‘acid rain’ in the coming week saying, “the acid rain alerts being attributed to NASA are false.” Talking to this news agency, he said the rumours about chances of ‘acid rain’ during April 20- 28, through messages, emails and other blogs were all false.Moreover, while acid rain can have a detrimental effect on human health, there are no indications that it will directly cause skin cancer to those who are exposed to it. Information about the effects of acid rain on human health published on America's Environmental Health Agency (EPA) website notes: Acid rain looks, feels, and tastes just like clean rain. The harm to people from acid rain is not direct. Walking in acid rain, or even swimming in an acid lake, is no more dangerous than walking or swimming in clean water. However, the pollutants that cause acid rain—sulfur dioxide (SO2) and nitrogen oxides (NOx)—do damage human health. These gases interact in the atmosphere to form fine sulfate and nitrate particles that can be transported long distances by winds and inhaled deep into people's lungs. Fine particles can also penetrate indoors. Many scientific studies have identified a relationship between elevated levels of fine particles and increased illness and premature death from heart and lung disorders, such as asthma and bronchitis.The EPA Acid Rain website also notes that the "precursors, or chemical forerunners, of acid rain formation result from both natural sources, such as volcanoes and decaying vegetation, and man-made sources, primarily emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx) resulting from fossil fuel combustion" and can occur when "gases react in the atmosphere with water, oxygen, and other chemicals to form various acidic compound". Acid rain has therefore been recorded in many parts of the world at many different times. Thus, it is simply ridiculous to suggest that an acid rain event only happens once every 750 years as claimed in the warning message. The bogus warning message does not contain any specific dates, which means that it is likely to continue its pointless journey around Cyberspace for many months or even years to come. Examples of this hoax message first began appearing in my email inbox, in early February 2010. Since these examples also spoke of circles around the moon "last month", the suggestion was that the acid rain event was to take place in late February. Of course, no such event occurred in February, nor did it occur in March as suggested in the next wave of nonsensical warnings. This trend is likely to continue month by month. Moreover, although the warning first began circulating around Nigeria and neighbouring countries, it does not specify any particular geographic region of the world. Thus, people all over the world are now receiving the warning, with many apparently believing that it pertains to their own region. Sending on this absurd warning will serve only to raise unnecessary fear and alarm within communities. If you receive this hoax message, please do not send it to others. And please take a moment to inform the sender that the message is a hoax. Oraz POYRAZ http://www.hoax-slayer.com/acid-rain-warning.shtml |
| Depending on how you look at it, something good can always come out of something bad. That's actually the case in a new study on greenhouse gases by NASA scientists and others. The researchers discovered that acid rain inhibits a swampland bacteria from producing methane, a greenhouse gas. Animation above: This movie from the U.S. Environmental Protection Agency highlights the science of acid rain, and its effects. Click arrow on bottom right to move to next image. Credit: U.S. EPA Methane, a gas that contributes to warming our planet, is produced by natural processes and human activities. Increased amounts of methane and other greenhouse gases in our atmosphere are warming the Earth beyond its average temperature. Carbon, heat and moisture are known to influence methane production by members of the Archaea, single-celled creatures. Under normal conditions, these microbes consume organic carbon in the soil for energy and release methane as a byproduct. Wetlands provide an ideal environment for these microbes. When acid rain drops sulfate onto wetlands, another type of bacteria, ones that reduce sulfate are able to outcompete the Archea, limiting the total production of methane. Wetlands may produce as much as 320 million tons of methane annually but only about half of that, or 160 million tons, is ultimately released to the atmosphere. The other 160 million tons never makes it to the atmosphere because it is destroyed via oxidation as it moves from wet soils below the water table through dry soil to the surface. Despite substantial oxidation, natural wetlands remain the single largest source of methane emission accounting for about one third of the global annual total methane.  Image to right: Inland wetlands are most common on floodplains along rivers and streams. Scientists have discovered that acid rain actually inhibits a bacteria found in swamplands from producing methane, a greenhouse gas. Inland wetlands include marshes and wet meadows dominated by herbaceous plants, swamps dominated by shrubs, and wooded swamps dominated by trees. Credit: U.S. EPA Region 1/Leo Kenney"It's a complicated process because multiple factors at microscopic to global scales interact in these processes," said Elaine Matthews, a scientist at NASA's Goddard Institute for Space Studies (GISS), New York. Matthews is co-author of the study on acid rain and methane in wetlands. "The maximum emission of methane from wetlands occurs when conditions are warm and wet, while the biggest reduction in methane emissions is achieved when the location of wetlands, sulfates contained in acid rain, high temperatures and substantial precipitation all come together, to reduce optimal methane emissions from wetlands." These factors vary over time and space. According to Matthews, by 1960 these counteracting processes probably reduced methane emission from wetlands to pre-industrial levels. However, methane emission is predicted to rise in response to 21st century climate change faster than sulfate suppression increases, meaning that wetland emissions of methane will begin to rise above those occurring before industrial sulfate pollution began. In order to determine how the acid rain interacts with methane in wetlands, lead author of the study, Dr. Vincent Gauci of Open University, United Kingdom and his colleagues took to the field. In the U.S., Britain and Sweden they attempted to determine if low levels of sulfate, like those in acid rain, affected methane emissions in wetlands. They applied several quantities of sulfate, similar to the amounts found in acid rain, to the wetlands they were studying. The results, acquired over several years, showed that these low doses of sulfate suppressed methane emissions between 30-40 percent.  Image to left: Coastal wetlands in the United States, as their name suggests, are found along the Atlantic, Pacific, Alaskan, and Gulf coasts. They are closely linked to our nation's estuaries, where sea water mixes with fresh water to form an environment of varying salinities. The salt water and the fluctuating water levels (due to tidal action) combine to create a rather difficult environment for most plants. Credit: U.S. EPA Region 8/Paul McIverMatthews and climate experts expect methane emissions to increase over the 21st century in response to climate change. They also predict that sulfate levels in rainfall will increase, especially in Asia. The authors have attempted to predict how this ecological balancing act will turn out for the 21st century. "When we used all the field data with the NASA computer models and applied it to a global scale, it shows that the effect of acid rain from 1960 to 2030 actually reduces methane emissions to below pre-industrial levels," said Gauci. The effect more than compensates for the increase in methane emission that would be expected as wetlands become warmer. In this way, acid rain acts like a temporary lid on the largest methane source. Gauci is cautious about the image presented by acid rain. "We wouldn't want to give the impression that acid rain is a good thing - it has long been known that acid rain damages natural ecosystems such as forests, grasslands, rivers and lakes. But our findings suggest that small amounts of pollution may also have a positive effect in suppressing this important greenhouse gas. Moreover, they point to how complex the Earth system is," he noted.  Image to right: Wetlands are among the most productive ecosystems in the world, comparable to rain forests and coral reefs. An immense variety of species of microbes, plants, insects, amphibians, reptiles, birds, fish, and mammals can be part of a wetland ecosystem. Physical and chemical features such as climate, landscape shape (topology), geology, and the movement and abundance of water help to determine the plants and animals that inhabit each wetland. The complex, dynamic relationships among the organisms inhabiting the wetland environment are referred to as food webs. Credit: U.S. EPA/ Mark Sharp Most attention has been given to the negative aspects of pollution but if scientists want to understand all of Earth's complexities and make better predictions of future climate we need to understand interactions among a suite of processes that are not always well understood. "That's not to say that acid rain is a good thing. Rather this study illuminates really well how we have to work to understand relationships among microscopic-to-global processes, at the same time that we attempt to represent them in relatively simple ways," Matthews said. While sulfate deposition results almost exclusively from human activities, it may serve to delay impacts from the increase of at least one greenhouse gas, methane, in the short term. The study recently appeared in the Proceedings of the National Academy of Sciences. NASA's Science Directorate works to improve the lives of all humans through the exploration and study of Earth's system, the solar system and the Universe.

-- Devlet birçok kişi tarafından yönetilirse bu ona, tıpkı giderleri toplulukça kaynaklanan şölenin tek kişinin hazırlayacağı bir şölenden daha üstün olması gibi bir üstünlük sağlar. Onun içindir ki çoğunluk, birçok durumda, her kim olursa olsun tek bir kişiden daha iyi bir yargıçtır. Ayrıca çokluk daha güç bozulur ya da kıstırılır. Kötü bir anında olan ya da konuya ilişkin çok güçlü duyguları bulunan bir kişinin yargısı ister istemez çarpık olacaktır. Öte yandan, bir kitlenin yargıda bulunması durumunda, kitleyi oluşturan her kişinin aynı anda duygulara kapılmasını ve yargısını çarpıtmadan ayarlamak güçtür.
