“Antarctica melts, in 2100 flooded the city at sea level, millions of refugees”

Scientists are sounding the alarm underestimated the melting of the Antarctic ice. Hundreds of millions of people will have to evacuate coastal cities if you do not block the greenhouse gas
The era Anthropocene – in which mankind has imposed its ecosystem changes such as to overcome the natural ability to self-regulation – takes the Earth to biblical floods in 2100. The countdown has begun according to a study published in Nature that calculates, for that date, an increase of 2 meters in sea levels, twice as much as expected, unless emissions of carbon dioxide emissions will be drastically reduced. This differential in the estimate would be born from the contribution undervaluation of the melting of Antarctic ice. It was believed that the snowfall in the South Pole would have “frozen” the bulk of the cap, but the study shows that it is not. In the past there have been ages when sea levels were higher, as in the period Interglacial between 130 thousand and 115 thousand years ago when it was greater than 9.6 meters, or the Pliocene (3 million years ago), when it was still higher. With one difference: at that time the coasts were not inhabited by hundreds of millions of human beings as today.
environmental refugees – whether it will be confirmed this analysis – will join the millions of war refugees and economic problems that already roam the world in search of safety. “These data – says the prof. Robert DeConto of the University of Massachusetts Amherst, who led the research – would mean disaster for many low-lying city, “adding that if the process is not stopped soon there will be a rise in sea level measured in the order of centimeters and not of millimeters. Speaking of the city just above the sea level also means saying metropolis like New York, Mumbai and Guangzhou inhabited by millions of people. According to the World Bank, the cities immediately at risk would be Miami, Boston and Nagoya and many cities in China, Vietnam, Bangladesh and Ivory Coast. The biggest danger is a breakdown of the ice dock around the south pole that would release a “piece” of the continent offshore intended to melt rapidly due to the storms increasingly virulent and the warming of the climate warm currents triggered. In the Antarctic there are also accumulations of 1000 meters which, if not frozen, could collapse under their own weight going to increase the volume of free water in the oceans. DeConto calculates that if you instead bring CO2 emissions to zero would stop the process and that there is still a 10% profit margin to stop the catastrophe that would force the evacuation of hundreds of millions of people.
Last February was the warmest ever according to data from NASA, of 1.35 degrees Celsius warmer than the average from 1951 to 1980 and the Arctic the most narrow ever since I started in ’79 with measurements of the ice surface. But the Arctic ice now “floats” on the northern ocean surface, so its melting does not raise sea levels. Are the glaciers of Greenland and Antarctica, which is a mainland firm ground, to cause the rise in water level when it melts, pour into the sea. A confirmation that the waters are warming with an unexpected rhythm comes from ‘ “epidemic” of coral bleaching observed in recent months from Indonesia to Hawaii that also affects the Great Barrier Australian north coast. A scientific task force has investigated 500 different points between Cairns and Papua New Guinea, noting that the phenomenon is ubiquitous. Bleaching is a form of “the coral stress” attributed mostly to the heating of the water. “It ‘was the saddest research trip of my life – said prof. Terry Hughes, coordinator of the National Coral Bleaching Taskforce – almost without exception every barrier on which we passed had significant levels of bleaching from the root to the top. We covered 4000 km. the oldest parts of the Great Barrier and found only four healthy colon. Gravity is much greater than the previous phenomena of ’98 and 2002 “.
