Changes in Impacts of Climate Extremes: Human Systems and Ecosystems

摘要: Chapter 3 evaluates observed and projected changes in the frequency, intensity, spatial extent, duration of extreme weather climate events. This physical basis provides a picture change But it does not by itself indicate impacts experienced humans or ecosystems. For example, for some sectors groups people, severe may result from relatively minor To understand triggered events, exposure vulnerability ecological systems need to be examined. The emphasis this chapter is on negative impacts, line with report's focus managing risks events disasters. Weather however, can often do have positive people In chapter, two different types human are examined: (i) events; (ii) less-than-extreme (in combination non-climatic factors, such as high and/or vulnerability). Where data available, examined sectoral regional perspectives. Throughout term 'climate extremes' will used refer brief 'extreme events' defined Glossary discussed more extensively Section 3.1.2.
