  • 2. Global Warming For the last 100 years the amount of carbon dioxide in the atmosphere increased by about 25%. Carbon dioxide passes short wave Solar radiation, and long-wave radiation absorbed by the Earth, and because his presence in the low temperature layers of the atmosphere is higher than when it would not. This is called. "Greenhouse effect" - an expression not just quite happily selected as the glass in the garden, the air temperature increased primarily due to mechanical prevention zagrejanog air to leave the garden. OBSERVED increase in temperature on Earth over the past 100 years, from about 0.3 to 0.7 K, the row size is in accordance with the increase that the various calculations should be expected due to the aforementioned increase in the concentration of carbon dioxide. Described effect of carbon dioxide joins the recently more and the impact of some other gases (chlorofluorocarbons, or Freon, methane, nitrogen oxides and ozone in the troposphere), which are artificially emitted into the atmosphere. How will certainly take a lot more time while increasing content of carbon dioxide does not slow down, it is expected that over the next 50 or 100 years to reach a significant increase in mean temperatures on Earth, perhaps even for 3 to 4 degrees. At the same time, due to expansion of ocean water and melting ice, and there will be any faster to further increase global sea levels perhaps a total of about 50 to 100 cm or more. By comparison, for the last 100 years, global sea level increased by about 10 to 15 cm. In addition, due to increased temperature, we should expect increased evaporation and increased rainfall. For now it is not clear whether, and how this will affect the schedule of rainfall, which can have serious consequences for agricultural production in some parts of the world. Global warming is the name of increasing the average temperature of the atmosphere and oceans especially in the 20th century. The causes and consequences of the causes and ultimate consequences of global warming, there is no scientific consensus. Most common is the theory according to which the consequences of global warming carbon dioxide and methane produced from industrial plants in developed countries. According to this theory, increased concentration of these gases leads to the so-called greenhouse gases in the atmosphere. Under pressure from the movement for environmental protection, many governments have accepted the theory, and signed the Kyoto Protocol, aimed at reducing emissions of these gases. [Edit] Opponents of global warming, opponents of global warming the other hand, recently reported in a number of scientists who challenge the theory global warming as a result of emissions of industrial plants and offering alternative explanations, whether in the form of changes in solar activity - what is used as evidence recently discovered climate change on Mars (melting polar ice caps) - either in the form of cyclic changes of cold and warm periods in Earth history , for which there is
  • 3. geological, paleontological and historical evidence. Citing similar changes on other planets as evidence against the theory of global warming has started a Russian astronomer Habibulo Abdusamatov. He has published papers in the National Geography "that the icy poles of Mars, which makes it hard carbon dioxide, reduce the previous three years. However, the increase in temperature on Mars seem consequence of large-scale sand storm that changed the flow and transparency of the atmosphere and the short-term phenomenon. Increase temperature to Neptune's moon Triton, which is also cited as evidence of the consequences of his ways, since direct sunlight falling on its southern hemisphere more than usual. The Jupiter is also observed phenomenon of increasing temperature, and appearance of new red spots in the top layer of its atmosphere, which may be the new focus of relatively small scale. The Pluto was observed rising temperatures, but on the basis of two observations in the interval of 14 years. [1] greenhouse effect occurs because the Earth and the molecules in the atmosphere absorbs the sun's heat. The heat that comes from the sun falls on the Earth, there will be refused and for the most part goes away from Earth. But so it was sometimes, however, the activities of people leaving large "scars" on our planet. Using an increasing number of different chemical compounds in daily life people change the composition of gases in the atmosphere of our planet. This changes the chemical composition of the atmosphere has led to that, instead transcalent declined from the surface, the atmosphere begins to heat reserves declined. In this way the whole atmosphere more and more heated. Many scientists are concerned and believe that greenhouse gases may lead to global warming which would have catastrophic consequences to life on the planet. Analysis showed that by 1800 the average temperature rose by 0.7 OC. Many may seem unrealistic to be something wrong with being on the planet will be a little warmer, but the global temperature increase would be much impact on living conditions, on our planet, and perhaps even led to life on the planet no longer be possible. With increasing temperature of the tropical areas would begin to spread from the equator. The climate would be completely changed, for pursuing climate change would change the flora and fauna all over the planet. It will be a great disturbance in the food chain. Food would be less, but more and more water. Ice in polar areas would begin to melt, and it would be much more rainfall. Melting glaciers may lead to the raising of the world has to perhaps a few meters, and it does not mean that only raised the sea, but the increased and rivers and lakes. This would lead to flooding areas inhabited by about one third of the total population. This is not a nice little script, but if people are thinking that this can not happen and begin to work intensively to reduce pollution consequences of global warming can become an important factor in our lives. It is believed that most consequences of global warming are: 1) Carbon Dioxide (CO2) - considered to be involved with this gas is about 50 - 55% of global warming. The main reason for increasing the concentration of this gas in the atmosphere is increasing use of fossil fuels (coal,
  • 4. oil, gas) and deforestation. 2) Hlorofluorokarbonati (CFC) - participating with about 25% of global warming. CFC compounds are used for making plastics and cooling devices. 3) methane (CH4) - about 12% share, occurs dissolution of organic compounds, but the largest amount of methane in atosferi comes from industrial plants 4) Nitrogen (I) oxide - involved with 6% in global warming. Mostly released in the industry, but large quantities of this gas is free and volcanic eruptions Yes, exactly so, it appears to us in the next 15 or 20 years waiting for the fall of global temperatures. These forecasts are presented two groups of renowned researchers, and nothing less than NASA and German scientists from the Max Planck Institute in Herndon and Lajbnicovog okeanografskog Institute in Hamburg. Difficult it is an amateur or mercenaries in the oil lobby. In a recent report, NASA says that Pacific decade of oscillation (PDO) of which we spoke earlier, definitely into the cold phase, which usually lasts about 30 years. This practically means that there is a change in the circulation of the Pacific, which controls directly and indirectly to climate throughout the country, due to the changes, the frequency of events La Ninja rise and weaken the influence of warm El Niño episodes. This should reduce the global temperature. PDO was in a warm phase from 1905-1945 when we were warming magnitude 0.16 degrees per decade, then we had a chill from 19451977 when the PDO was in a cold phase, and then with a warm phase from 1977-2008, we had a global Warming similar magnitude as those in the first half of the twentieth century, with the last 10 years virtually flat trend. In the opinion of NASA scientists, now we enter again in the cold phase, which should cause a trend of decreasing temperature.
