The opinions of climate scientists on the issue of climate change on Earth are diametrically opposed. Recently, most often heard predictions that global warming is coming. Proponents of this theory argue that after 2010 , the global temperature will rise rapidly, the total global warming will accelerate, and by the middle or end of the century in Europe will become warmer by about 10 degrees. It is also expected that the warming and rising levels of Oceans in the future will continue for millennia, even in the case of stabilization of greenhouse gases in the atmosphere. In addition to rising sea levels increase in global temperatures will lead to changes in the quantity and distribution of rainfall. The result may be more frequent natural disasters such as floods, droughts, hurricanes and other fall crop and Many species will disappear. Causes of climate change are not completely clear, but among the major called: – change the Earth's orbit, changes in solar activity, volcanic emissions and the greenhouse effect. Perhaps check out Jeffrey L. Bewkes for more information. But if even one and a half years ago, the main culprit was declared man of warming and the greenhouse effect, it is now official climatology tends to natural factors.
According to the Climate (change temperatures over the last two hundred years) the average temperature on Earth rose. Part of climate scientists do not agree with the above – they claim that the observed warming is too short time, so can not be confident enough to say whether it happens at all. And finally, another squad of scientists predicts the imminent global cooling. They argue that life on Earth (including ) and entirely totally dependent on incoming solar radiation. And humanity greatly exaggerates his importance in this process. Current and expected the foreseeable future, the industrial impact on the environment is not capable change the world as the sun. Everything on this planet depends on it.
And in the first place – the climate. There is a long solar cycle – some 200 years. During this time, activity and luminosity of the sun gradually reduced to a minimum, and then increased. Scientists, advocates of the cooling, determined that the planet now live in a "cooling" of the Sun stable temperature reduction on a global scale will begin in 2013-2015. And last approximately half a century. In the years 2055-2060 comes a deep minimum temperature. The Nordic countries are expected not disastrous, but very important changes. The coming cold will lead to a significant increase in the area of snow and ice cover. After this period of cold weather cycling by law must come again warming. Global temperature will increase gradually at the beginning of XXII century. Neither cooling nor warming can not last longer than they meted out 200-year fluctuations in the size and luminosity of the sun. What is really real and grave threat to humanity? It is still not clear. Scientists argue. Perhaps the truth lies, as so often happens, somewhere in between? Materials from Wikipedia.org Yuri Chashin 16/07/2009
