In their opinion, conditions on earth will change dramatically by 2100. It will happen partly because the water from melting ice sheets in Greenland and Antarctica will cause extreme weather conditions and unpredictable temperatures.
“Under current global policy, we are moving to a 3-4 degree warming above pre-industrial levels, resulting in a significant amount of melt water from the Greenland and Antarctic ice sheets falls into the Earth’s oceans. According to our models, this melt water will cause significant disruptions of ocean currents and change the levels of warming in the world” – quoted by the media associate Professor Nick Golledge from the Antarctic research centre at Victoria University of Wellington in New Zealand.
Modeling of the ice cover shows that the most rapid sea level rise likely to occur between 2065 and 2075 years, which, in turn, affect air temperature. In some parts of the world, such as island States in the Pacific, there will be significant sea level rise, while the ice near the boards he will go down hard . Upon receipt of the warmer melt water into the oceans, for example in the North Atlantic, major ocean currents such as the Gulf stream will weaken. This will lead to higher air temperatures in the Arctic, Eastern Canada and Central America, as well as cooler temperatures in North-Western Europe across the Atlantic.
Despite the confident statements of foreign bodies, Russian scientists are less prone to such devastating conclusions. As told “MK” the Deputy Director of the Institute of atmospheric physics..M. The earth RAS Vladimir Semenov, a similar theory has been popular at the beginning of 2000-XX. Some climatologists speculated that the Greenland glaciers will melt and water will desalinate the oceans, this will change the heat transfer, and in Europe frosts. But these predictions were not confirmed. Moreover, according to him, even if you remove all the usual circulation of water flows, in Europe will be colder..but only by 5-6 degrees.
– I can’t say that we got some new knowledge that can revolutionize the understanding of climate change in General, says Semenov. – Of course, changes occur and will occur, but until the end of the XXI century is certainly nothing catastrophic is expected. Yes, indeed, the Greenland glaciers will melt, but they do it very slowly. That is significantly they will melt in 300 years, if not more. And even if you do this completely, which is unlikely to happen, it still will not give a critical rise in global sea level. There are more than 30 models for further developments, and none of them showed non-linear development of the situation, that is, no surprises will not.
