This paper analyzed the spatiotemporal patterns and influencing factors of the hazards and mortality, selecting the global climatological, meteorological, hydrological disaster data from 1965-2016. The paper explored the relationship between regional differences of hazards and climate change, further, the influencing factor of mortality were analyzed as well. The results showed that: (1) the total number of the three types of hazards showed an increasing tendency in time, while the mortality per hazard was decreasing year by year. (2) The frequency and deaths of hydrological hazard had the highest proportion in developing countries with high mortality, while the developed countries were predominantly affected by meteorological hazards. (3) The annual frequency of flood-landslide-storm in climate wetting trend zone has grown faster than that in climate drying trend zone; moreover, the hazards corresponding to the precipitation/temperature enhanced fluctuation zone has grown faster than that in weakened zone. (4) The impact of the three types of disasters on mortality was related to the climate fluctuation and the level of economic and social development. The annual frequency of hazards and GDP level were the most important factors in the mortality.
