At least 2.5 million people have been killed in natural disasters over the recent 48 years. The number of casualties over the recent 20 years made up 1.6 million people, the UN said. Rob Vos, the director of the Development Policy and Analysis Division of the Department of Economic and Social Affairs (DESA), said that the number of natural disasters taking place in the world nowadays has quadrupled in comparison with the 1970s. The disaster-related economic damage has increased at least seven times. The authors of the report delivered at the UN headquarters in New York at the session of the UN Economic and Social Council did not specify the reason why natural disasters started happening more frequently in the world today. They said, however, that the frequency of catastrophes could be linked with the global climate change. http://english.pravda.ru/science/earth/04-07-2008/105690-earth-0

Reality check: The average annual percentage of the global population killed by natural disasters decreased 10-fold from the period 1964 to 1968 compared with the period 2000 through 2004, from 0.01 percent (roughly one killed for every 10,000 people) to 0.001 percent (one in 100,000) respectively. At the same time, the average annual number of recorded disasters increased five-fold between 1964 through 1968 (64 per year) and 2000 through 2004 (332 per year). The events that continue to result in the major number of fatalities are the relatively small percentage of events that occur with large recurrence intervals, such as massive floods, strong earthquakes and direct strikes from intense hurricanes, or events that are unusual in the area in which they occur.
