The rising frequency and strength of extreme weather events, like floods, tropical storms, landslides and, wildfires, are highly likely to increase the occurrence as well as the scope of climate-related disasters. Where extreme weather events interact with human systems, they have the potential to generate widespread mortality, morbidity, and health issues to people present in the hazard zone. Through the destruction of and damage to vital ecosystems, resources, livelihoods of people, infrastructures, and essential services, natural hazards can produce critical adverse consequences, including increased resource scarcity and/or competition, heightened inequality and social tensions, forced displacement and/or migration, and destabilized institutions. Through these mechanisms, natural hazards can pose substantial risks to overall societal stability and security. Climate security, in this report, implies the relationship between national security and human security and climate change through the direct and indirect security threats posed by climate change-related natural hazards. National security is a fundamental condition to protect human lives and to advance human security, including human rights. Natural hazards include events or trends directly influenced by climate change, including coastal and riverine floods, tropical storms (cyclones, hurricanes, typhoons), landslides, droughts, heatwaves, and wildfires. Security threats include those adverse impacts of natural hazards on human societies that spill over into higher-order security risks, including significant natural disasters requiring military responses or natural hazards resulting in threats to critical resources and infrastructure, wide-scale forced displacement, political instability, or intra-state violence and conflict. Climate change and natural hazards generally do not directly produce intra-state violence or conflict. More often, climate change acts as a threat multiplier by triggering or aggravating existing pressures within societies, including demographic, social, economic, or political strains, that potentially develop as underlying drivers of instability and insecurity. Especially when climate change overburdens the capacity of governments to effectively deal with these accumulating pressures, societies become more vulnerable to social or political instability. This risk methodology and assessment focuses on the risks to national security generated by climate-related disasters and comprises elements like territorial integrity, ecological Climate Security Assessment 9 security, economic security, physical security, human security and, social and political stability.
