Natural Disasters Index (ND) — global changes of climate and natural disasters — measured by the total number of people per year who died of earthquakes, draughts, hurricanes, floods. In the recent decades changes of climate are among the main global problems encountered by the world community. This problem is in the focus of attention not only of climatologists, but also of politicians, it was discussed at the UN conferences on environmental problems in 1972 in Stockholm (Sweden) and in 1992 in Rio de Janeiro (Brazil), Johannesburg (South African Republic). One of the most important decisions of those conferences was the UN Convention on the change of climate. Today, among experts there is no undivided opinion regarding the causes of the observed changes. However, all of them come to the conclusion that these changes are caused by anthropogenic phenomena which overlap with the natural climatic 41variations. And the impact of the latter ones still is stronger than those connected with the changes of the Earth surface and the greenhouse effect.
