Irene hurricanes, tornadoes and flooding in Missouri and Mississippi Rivers that contribute to record U.S. weather-related disasters cost at least $ 1 billion this year, according to the National Oceanic and Atmospheric Administration.
A Total of 12 natural disasters have killed 646 people and caused around 52 billion in damages, exceeding the previous all-time high of nine disaster in 2008, NOAA reported Wednesday.
Six of the worst disasters, killing 560 and causes billion in insurance losses of 12.2, derived from the tornado striking 23 countries in April to June. According to the 1910, there has been an increase in weather-related disasters since 1970.
Social factors and climate take into account the part of the increase, said Karl. The population has grown since 1980, people have a greater awareness about insuring their property and harta-benda are more expensive, all of which increase the monetary damage figures, he said.
