According to scientists from Stanford University, the average summer temperatures in the coming years will become higher and higher.

After analysis of about fifty of computer climate models that are based on historical data of weather stations from all major parts of the world, it was concluded, that the particularly strong increase in summer temperatures will affect the mid-latitudes - Europe, North America, Central Asia and China. Already this year in China, there is drought, the most powerful in recent years of meteorological observations. But residents of the tropics, too will expect an increase in average temperature, but in the longer term.

According to scientists, the increase in summer temperatures may have an impact on human health and agricultural development. As an example was given of the summer heat in 2003 in Europe, when affecting 40,000 people. The analysis found, that across the Northern Hemisphere as a whole in 2010, the average temperature has risen to 0,963 ° C, which is never seen in the last hundred years of regular meteorological observations.

In Russia, the country as a whole, summer 2010 was the hottest: in May and July 2010 the average air temperature has reached the absolute maximum of 120 years of regular Russian meteorological observations, which are conducted since 1891. But because of the huge size of Russia, climate change will occur is very uneven. If in the northern regions of Russia are expected surplus of fresh water due to an anticipated increase in rainfall, the country's southern regions, particularly in the Stavropol and Krasnodar regions, Kalmykia, Volgograd region problems with fresh water will become more acute. Due to changes in rainfall, grain yields in the fall by 10-13 percent, and in southern Siberia - even at 25 percent. But upon further warming will increase area of cultivation of heat-loving crops, in some southern regions of Russia in 30 years will be even grow sub-tropical crops. One positive point in the future warming- uncomfortable zone will be shifted by at least 60 kilometers to the north. Permafrost zone, which occupies about 58 percent in Russia in 30 years will move into western Siberia by 200 km to the north. It already can damage the stability of many buildings and structures, built in these areas, taking into account the factor of permafrost, especially the numerous gas and oil pipelines, which supply minerals from Siberia to Europe and China. As a result, the threat of destruction will be exposed to most of the houses in Yakutsk, Vorkuta, Tiksi, Norilsk and other cities in permafrost regions.

By 2040, in the countries of Southern Europe, Latin America and much of Asia, the Middle East, and Africa expected drought. The worst scenario that could happen, suggests that there will be large-scale drought in the country where most of the food - these are the countries of North America, Europe and Asia. As a result of a decline in rainfall will be drying up of rivers and depletion of fresh water. This will have reduced food supplies, famine and epidemics, as well as uncontrolled migration of local people from areas of distress. Worldwide tougher increase international tension, there may be war for power and water sources. At the same time in areas with traditionally dry climate (especially in Australia), rainfall could increase dramatically, and increase the number of floods that cause the reduction of use of agricultural land is not suited to such an abundance of moisture. In 2010 and early 2011, Australia has experienced a number of major floods, which resulted in substantial property damage. Thus in these areas is also expected shortages of food, but an abundance of fresh water.

And it's not just a prediction, it is an alarm for the world, accustomed to a gradual change in climate and do not pay much attention to small changes in climate. List of news about the unusual phenomena in the world can be found here:
