Cascading climate events occur when an extreme event triggers a sequence of secondary events within natural and human systems that causes additional physical, natural, social or economic disruption. The resulting impact can be significantly larger than the initial hazard . Each step in a risk cascade can generate direct  and secondary  losses. Risks from these cascading impacts are complex and multi-dimensional . For instance, combined droughts and heatwaves increases risks of urban water scarcity , as well as increasing wildfire extent and lowering snowpack conditions that affected peri-urban settlements adjacent to forested areas, as observed in California during the 2014 drought . Similarly, heatwaves can increase the risk of mortality associated with air pollution .
