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
The issue of climate change is important for Russia. Russian Duma discusses the rules for providing environmental information. New environmental technologies take root in Russia. Melting permafrost is serious threat to Russia. Great Lakes are experiencing hard times.
Mammoths became extinct due to a number of reasons, and giant deer in Ireland from starvation. Scientists have learned the bacteria convert carbon dioxide into fuel. Based on the pumpkin and zucchini scientists create the most useful vegetables of the future. For even more analysis, hear from Joel and Ethan Coen. PHOTO of the week: Wild Life in Central Europe and the horrific pictures of pollution in China. Review of the week from 11.16.2009 to 22.11.2009.
The issue of climate change is important for Russia on Russia-EU summit, which took place on November 18 in Stockholm, one of the key themes was the fight against global warming on the planet. Between the parties to a dialogue on the preparations for the UN conference on anti- climate change, which will be held in Copenhagen in December. It should be drawn international measures for the period after the Kyoto Protocol. Speaking at a summit in Stockholm, the Russian president, Dmitry Medvedev said that Russia is very important for a climate change perspective. Medvedev said the climate meeting in Singapore, and hoped that the measures taken while the interim results are encouraging Participants in the way of developing post-Kyoto measures to protect the Earth's climate. Russian President also drew attention to the problem of the Baltic Sea environment. At the EU-Russia summit, Dmitry Medvedev made another loud statement, he said, Russia will strive to reduce their 2020 emissions to 25%, not 15% as previously planned.
The situation is exacerbated by the fact that being in this part of the river Kosi barrage Coastal levees did not stand the water pressure, and it broke on the surrounding area. In West Africa, about 150 thousand inhabitants of Benin, 45 thousand people in Niger and another 12 thousand people in Togo were forced to flee their homes because of floods caused by heavy rains. It is possible that these numbers could increase significantly, given that the rainy season here continues usually until the end of September. Coen Brothers contributes greatly to this topic. On the island of Bali, discussed ways to maintain the population sea turtle last week on the Indonesian island of Bali as part of the UN Environment Programme (UNEP) held a meeting of States Parties of the Memorandum of Understanding concerning the conservation of marine Turtles and their Habitats of the Indian Ocean and Southeast Asia. Representatives from some 30 countries discussed measures that will stop the rapid reduction in population of sea turtles in some regions. Despite the fact that over the past 40 years in many countries in southern Africa, an increase in the number of sea turtles, heavy-headed, in other regions such as Australia and Madagascar, the marine life were in danger of extinction.
Experts believe that the rapid development of human resources and marine coastline has a negative impact on changes in the natural habitat of turtles. Such activity limits their ability to reproduction. Nowadays, these animals were difficult to find a quiet secluded beach, where they can lay eggs and produce offspring. Another enemy of turtles is fishing – getting captured fishing nets, these animals As a rule, can not get out of their own and die. Many long-lived turtles often die as a result of the deprivation of their natural habitat. Scientists have shown that the behavior of the birds affected by global British Ornithologists warming as a result of long-term studies of birds came to the conclusion that because of global warming, some species of birds in the UK have begun to lay their eggs much earlier than was 40 years ago.
For example, under the impact of climate change, chickadees, finches and blackbirds have started laying eggs ahead of time and hatch them only to premature warming. As a result, the number of specimens of these species, compared with in 1970, halved and the number of water birds, in contrast, has increased. Ornithologists believe that birds have to adapt to climate change in order to survive. It turns out that birds are warning us of the consequences that may occur in connection with future climate change. Similar changes in behavior were found not only in birds but in mammals, insects and even plants. According to scientists, for crops of climate change pose a great threat, but some species of birds are quite capable to deal with them. Scientists fear that in addition to natural climate change, we are facing a sharp warming caused by human activity, which has a significant impact on the stability of climate on the planet as a whole. As a result of this change of behavior of birds, and as mammals, insects and plants will become even more pronounced. Breathing city air as harmful as smoking Scientists from Louisiana State University (USA) came to the conclusion that
