; and (3) these effects are threat multipliers that will aggravate stressors abroad such as poverty, environmental degradation, political instability, and social tensions—conditions that can enable terrorist activity and other forms of violence; Whereas the Department of Defense report, National Security Implications of Climate-Related Risks and a Changing Climate — (1) states that global climate change will have wide-ranging implications for United States national security interests over the foreseeable future because it will aggravate existing problems, such as poverty, social tensions, environmental degradation, ineffectual leadership, and weak political institutions, that threaten domestic stability in a number of countries; and (2) identifies four general areas of climate-related risks: persistently recurring conditions such as flooding, drought, and higher temperatures; more frequent and more severe extreme weather events; sea level rise and temperature changes; and decreases in Arctic ice cover, type, and thickness; Whereas the Director of National Intelligence’s 2017 Global Trends Report determined that— (1) changes in the climate will produce more extreme weather events and put greater stress on humans and critical systems, including oceans, freshwater, and biodiversity; (2) these changes, in turn, will have direct and indirect social, economic, political, and security effects; and (3) extreme weather can trigger crop failures, wild­fires, energy blackouts, infrastructure breakdown, supply chain breakdowns, migration, and infectious disease outbreaks, and will be more pronounced as people concentrate in climate vulnerable locations, such as cities, coastal areas, and water-stressed regions; Whereas the Department of Agriculture has determined that climate change is likely to diminish continued progress on global food security through production disruptions that lead to local availability limitations and price increases, interrupted transport conduits, and diminished food safety, among other causes
