Studie der Weltwetterorganisation, 23.7.2021 (engl. Originalfassung)
Water-related hazards dominate the list of disasters in terms of both the human and economic toll over the past 50 years, according to a comprehensive analysis by the World Meteorological Organization (WMO).
Of the top 10 disasters, the hazards that led to the largest human losses during the period have been droughts (650 000 deaths), storms (577 232 deaths), floods (58 700 deaths) and extreme temperature (55 736 deaths), according to the forthcoming WMO Atlas of Mortality and Economic Losses from Weather, Climate and Water Extremes (1970-2019).
With regard to economic losses, the top 10 events include storms (US$ 521 billion) and floods (US$ 115 billion), according to an excerpt from the Atlas, which will be published in September.
Floods and storms inflicted the largest economic losses in the past 50 years in Europe, at a cost of US$ 377.5 billion. The 2002 flood in Germany caused US$ 16.48 billion in losses and was the costliest event in Europe between 1970 and 2019. However, heatwaves had the highest human toll.
The data show that over the 50-year period, weather, climate and water hazards accounted for 50% of all disasters (including technological hazards), 45% of all reported deaths and 74% of all reported economic losses at global level.
