Reached a critical point. Europe will flood huge tsunami?!

In the course of the dispute is still pending on the occurrence of global warming and its potential consequences, you can hear two contradictory positions. Some researchers suggest that the currently observed trend does not differ specifically from the cyclical changes occurring in the past. Some scientists, however, thunders that the situation becomes more dramatic. In their opinion, for example, systematically shrinking the ice in the Arctic Ocean could lead to a real disaster. Is in the near future, therefore we are threatened - as claimed by some experts - Arctic tsunami? melting of the ice cover in the North Pole is not new. Scientists monitoring the situation for years watched as the surface in summer underwent stopnieniu to "rebuild" in the winter. Tim Lenton of the University of Exeter, who, since 1979, leads the observations of this region of the world, day in and day collecting data,claims that since 2007 the situation deteriorated significantly. The difference between the ice cover in winter and summer has proved to be less. At this time, the area of permafrost, after reconstitution, it is about 1 million square kilometers smaller than it was several years ago.The system has reached a tipping point. He is echoed by experts from the American research center dealing with the situation in the area of geographic poles and the cryosphere, who also noted that in subsequent years the ice in the Arctic is not regeneration. As the experts at the U.S. National Snow and Ice Data Center, it is inconsistent with the model developed once the growth dynamics of the ice surface, which in winter should be completely reconstituted.
What caused the sudden change still can not be fully explain ..been speculated, however, what such a conversion may result in adverse effects. Among the darkest scenarios, there are those that indicate that warm ocean currents from the Arctic region may eventually lead melts the glaciers in the eastern of Greenland.
So I really hope our brothers alien will help us...and save our continent..far rumors about global catastrophe give much of thinking...
