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
