In the near future, the flood of the century can occur every three years

February 13. In August, Hurricane "Irene" swept through the Caribbean and the eastern part of the United States, leaving a wide strip of ruins. Rearing them water rolled over the dam, flooding the coastal and inland areas. Many said that it was the most devastating flood of the century.

However, researchers Massachusetts Institute of Technology and Princeton University (Both — USA) found that climate change such storms will fall upon the land much more often — every 3-20 years. But the floods occurring today "once in five hundred years," will occur every 25-240 years.

So build embankments and dams higher, or they will fill with enviable regularity.

To simulate present and future storm threat in the vicinity of New York researchers combined four climate models with a specific model of a hurricane. In a 200-kilometer radius Battery Park, Located on the southern tip of Manhattan, has been played 45 thousand storms.

We studied two scenarios — "current conditions" (climatic parameters characteristic 1981-2000) and the "climate of the future" (forecast by the Intergovernmental Panel on Climate Change on the years 2081-2100 with the condition of moderate rates of carbon dioxide emissions).

Today, "storm the century" for New York City is a flood of about two meters. About once every 500 years, the region covers a three-meter water. Worst flooding in New York City was recorded in 1821 — 3.2 m Note that the piers of Manhattan have only one and a half meters in height.

The study is published in the journal Nature Climate Change.
