Last year, 42 million people have fled their homes because of irreversible climate change


Last week, the UN announced the opening of November 28, 2011 conference on the problems of global warming. The event, called the United Nations Climate Change Conference, held in Durban (South Africa). It was visited by representatives of 40 countries of the world. However, scientists have noted with alarm that already occur in nature irreversible changes have led to an incredible increase in global average temperature of the planet, more frequent devastating natural disasters, the extinction of many species of animals and displacement from their homes of millions.The conference program is now being developed in Durban. But even the data scientists who are already incorporated into it (and it works 2.5 thousand specialists from 130 countries of the world), unequivocally demonstrate the progression of global warming. Scientists generally agree on an assessment of what changes will occur on our planet as a result of this process. The stunning results of his many years of research have already provided the European and American scientists working for the UN. It turns out that the earth's average temperature has increased since 1880 by four degrees Celsius. And disappointing forecasts, in this century, the temperature of our planet may grow by 6.4 degrees Celsius. Stipulate that globally it is very, very much.The agenda for the November UN conference also included scientists report on the impact of melting ice on the environment in different parts of the globe. The greatest effect of global warming already observed in those regions of the world that are close to the Arctic zone: Alaska, western Canada, the Far Eastern territories and regions of Russia. The average temperature of the earth's crust in these areas exceeded the average temperature rise globally by half.Researchers' calculations, the melting of the Arctic ice could be completed by 2040, and then we will nesdobrovat. For example, in a large national park, located in the mountains of the U.S. state of Montana, today there are only 27 of the 150 glaciers that existed there in 1910. In northern Canada warming is stably implies the coming of spring a week earlier than usual. The formation of ice on rivers and other water bodies starts a week later than the usual time.There are quite recent examples. Almost two weeks ago, the water level in the Missouri River, which flows through the territories of many states in the U.S. unexpectedly rose more than 1.5 meters high. Located on the river towns were flooded. And just three days ago in a flash flood flooded the nuclear plant on the outskirts of the town of Fort Calhoun (Nebraska). The situation in the surrounding areas of the Missouri River can be compared to the catastrophe caused by the tsunami occurred in March of this year in Japan. The principal difference is that the Fort Calhoun Nuclear Station is equipped with a firewall of any natural disaster, do not let the elements eventually damage the reactors.Global warming is manifested in different forms. Natural disasters such as extreme temperatures (tens of degrees in no time), prolonged storms and hurricanes, torrential rains and drought, causing forest fires, turned now in many parts of the world in common. And every year more and more such disasters lead to a real disaster: the disappearance of water, reduce the acreage and the destruction of the natural raw food for the animals. International research organization "Center for Monitoring of internally displaced persons» (Internal Displacement Monitoring Centre — IDMC) recently summarized the results of the study of life of tigers in their habitats. Researchers concluded that 100 years ago, the population size of these animals was 100 thousand individuals. Now, because of the lack of the once suitable for areas of their lives the same level of food and drinking water there survived only 3.2 thousand of these animals.The most pessimistic scientists studying global natural processes already wondering about what might happen in the long term with people. At the same time, experts IDMC, decades of exploring the human condition in the world, estimated that only one in 2010 to almost 42 million people (!) Fled their homes because of the devastating effects of global warming. By the way, in 2009, for the same reasons forced migration had to make half as many people. Among the main causes of this kind of migration — unbearable heat and drought, floods, storms. For example, only one China in connection with a string of floods last year had to move to other countries about 15 million refugees.
