On Earth, begins the era of superstorms


Hurricane "Sandy" opens up a whole era of natural disasters


Hurricane "Sandy" struck the east coast of the United States, opens up a whole era of natural disasters, the effects of which mankind will be able to evaluate in the coming decades.

"This is a harbinger of things to come. Increasing the number of storms and rising sea levels pose a growing threat in the coming decades," — CNN quoted Professor Michael Oppenheimer of Princeton University.

The Intergovernmental Panel on Climate Change warned in 2007 that the average global sea level rise of 17 to 58 cm by the end of this century. However, all subsequent projections indicate that the melting of sea ice in the Arctic trigger level rise of 76 centimeters.

"Climate change is likely to increase the intensity of storms and their magnitude, resulting in a significant enhancement of storm surges," — says Oppenheimer.

For three decades, melt about 2 million square feet. km of Arctic sea ice. It is projected that by 2100, the Arctic could lose almost all of its ice cover, but some scientists believe that it will happen much sooner.

"That's how it works: loss of sea ice means more rapid increase in water temperature. Surface temperature of the sea off the coast of north-eastern part of the United States is currently the highest in history. This is like a refrigerator with the door open," — said Walter Meier of the National data center for the study of snow and ice at the University of Colorado.

"Large fluctuations in the movement of air masses allow cold air from the Arctic to move south, while warm, moist tropical air moved north," — said Jennifer Francis of the Institute of Marine and Coastal Sciences. According to her, this is what happened when the arctic and tropical weather fronts collided and formed as a result of "Frankenshtorm."
