Arctic ice threatens nearly a billion people

Due to the melting of Arctic ice in the area of ​​emergency may be about 800 million people, said Emergency Situations Minister Sergei Shoigu. Also, due to subsidence threaten the destruction of many product lines, laid over permafrost. Their predictions with the ' Truth. Roux ' shared Nobel Prize with the IPCC, Professor Gennady Menzhulin.
' Indeed, the topic of current. After all, the Arctic - the main link in the prediction of sea level rise caused by global warming. The number of ice here reaches incredible values, and if it is melting, according to preliminary estimates, sea levels will rise by approximately 57-60 meters.

But recently, based on the results of research, many scientists have questioned the hypothesis that the accelerated melting of Arctic ice, for the most part of its global warming impact. It is assumed that a continuation of natural processes.



Patterns of climate variability of sea ice in the Arctic and Antarctic, as well as other components of the Earth's climate system, due to changes in the polar vortex, which are associated with zonal flows in the atmosphere of the temperate and high latitudes.

Print Font Size Send druguTak in warm climatic era polar vortices deeper, stronger zonal flows, and in the cold period marked opposite changes. All this leads to the fact that the area of ​​ice cover varies considerably during the year.

Analysis of the results of the calculations the area of ice cover during the period of satellite observations reveals the tendency to a more rapid reduction of sea ice in summer than in winter. Minimum area of ​​Arctic sea ice reaches, usually in September, at the end of the melt season. That is, this is the usual cyclical natural process. Another thing is that the melting of ice, as well as other manifestations of the elements - fire, earthquake, tsunami - may pose a threat to human security. Therefore, advance to take appropriate measures, of course, a useful thing '.



The importance of the problem is the fact that today in Moscow under the auspices of the Russian Geographical Society ( RGS) starts the International Arctic Forum ... Discuss issues relevant to the region, have gathered well-known Russian and foreign scholars, representatives of nongovernmental organizations and the business community, politicians, heads of ministries.

Among the main themes - climate change due to the consequences of human activities, as well as issues related to natural resources and the prospects for sustainable development in the Arctic.

Particular attention will be paid participants in the forum of abnormally high temperatures this summer, which were recorded not only in Russia but all over the planet. This led to the fact that the area of ​​Arctic sea ice has reduced almost two times faster than before.

Russian scientists believe that the rate of melting of the ice can be broken a record in 2007, when the Arctic ice cover has decreased by one third.

According to RIA ...

Describing the threat Shoigu noted that due to the melting of Arctic ice may prosest pile fields in the Arctic Circle, which will lead to cracks in buildings. Furthermore, the permafrost are many product lines, namely - linear structures that are most susceptible to damage by subsidence.

' In the near future will create an integrated group which will examine this issue and develop solutions that must be taken in the future ...


Also the head of Emergency and RGS reported that Russia and the Arctic countries should develop a common approach to security in the Arctic. 'This is the case when necessary and shared environmental requirements - said Shoigu. - Russia in the Arctic is going to create ten rescue stations. ' A similar decision to make and our partners ' - he said.

Meanwhile, scientists do not jump to conclusions and findings. They claimed that despite the rapid melting of Arctic ice, a record in 2007 (then in the Arctic has been fixed minimum amount of ice during the whole observation period ) still survived. According to scientists, some experts forecast that the ice in the Arctic will completely disappear in the next few years, the erroneous.

The researchers conclude that this year the area covered by ice of the Arctic Ocean was more than in 2007 and 2008, but fewer than all the previous observation period, from 1979.
