ABSTRACT
This chapter reviews that how climate change might affect the future frequency and intensity of extreme weather events. Climate scientists use specific mathematical/statistical models in order to represent and understand the implications of climate change. The coping range or vulnerability of a system depends on the inherent ability of the system to respond to and recover from climate change. Vulnerable groups are said to be at risk from climate extremes because definitions of risk involve concepts of vulnerability. The term 'climatic hazard' is often used to capture the climate extremes, in addition to changes in annual averages, to which a system under study is vulnerable. Climate-related disasters cause more deaths and property loss than other natural hazards. Many economic and social systems including agriculture, forestry, settlements, industry, transportation, human health and water resource management have evolved to accommodate some changes in average conditions, particularly if the changes are gradual.
