Change of temperature and mode of loss of grounds can very serious affect to availability of functions of crops, potable water and an opportunity of cultivation of cattle. Experts warn that shortage of those vital resources can lead to enmity between people and nations. As a result of global warming the food and potable water can become resources because of the countries are ready to go in the conflict and even to be in war.
In the research, published in last number of magazine Human Ecology, it is visible, that such happened in the past ,also. Authors have analyzed 899 confrontations which have happened in China in period between 1000th and 1911th and have concluded : precise connection between frequency of occurrence of wars and changes of temperature is founded . The history progress as a spiral and repetition is characteristic of history cycles.
« At war-world cycles of the Chinese history, for example, the biggest influence was presented with greater insufficiency of agricultural products which have been caused by long-term change of a climate », - writes the basic author of research David Zhang from Hong Kong University .
A few American military leaders who have retired, warned in the April official report about dangers of global warming -wars because of clean water, the refugees who have lost homes because of a raising of a level of sea water, famine and illnesses.
Probably, that global warming will positively affect on productivity in some places of a planet. But in other places and, first of all in tropical latitudes, conditions will worsen, the co-author of research William Easterling from university of Pennsylvania informs.
As a result of warming some people, certainly, will win. However, will be much more losers. As William Easterling said, probably will begun general war, and because of that all international institutes and the global market be supposed to stop the work. But changes in distribution of resources, undoubtedly, encourage developments of the international tension.
The result received by authors of research, does not prove, that wars arise because of global warming. But it’s obviously that correlation between global warming and the international military conflicts exists.
One more motive for conflicts can become stocks of oil on the Earth which constantly decreasing,. In the countries with the developed production- oil is strategically important resource. And if necessity for oil will not be satisfied, it becomes the reason of tensions among the countries.
