; Whereas the emissions reductions pledged by the United States under the Paris Agreement may save nearly 300,000 lives in the United States by 2030 as a result of positive health outcomes corresponding to lower air pollution; Whereas studies conducted by the NASA Earth Observatory determined that as the oceans have warmed, polar ice has melted and porous landmasses have subsided, global mean sea level has risen by 8 inches (20 centimeters) since 1870, and the rate of sea level rise is faster now than at any time in the past 2,000 years, having doubled in the past two decades, putting 55 to 60 percent of United States citizens who live in counties touching the Atlantic or Pacific Ocean, the Gulf of Mexico, or the Great Lakes at risk from the effects of sea level rise; Whereas the Department of Defense has identified climate change as a threat multiplier that will increase global instability and conflict with the potential to increase terrorism; Whereas the 2014 Quadrennial Defense Review states that [t]he impacts of climate change may increase the frequency, scale, and complexity of future missions, including defense support to civil authorities, while at the same time undermining the capacity of our domestic installations to support training activities, and notes that— (1) climate change may exacerbate water scarcity and lead to sharp increases in food costs; (2) the pressures caused by climate change will influence resource competition while placing additional burdens on economies, societies, and governance institutions around the world; 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
