Climate Change or Anthropogenic Climate Disruption (AGD) poses the greatest danger to America's national security, and to life on earth as we know it, yet neither political candidate has paid it more than lip service.

Yet, as we spend Billions upon Trillions of dollars on wars in the Middle East (including, without limitation the "War on Terror") we spend a pittance preparing to ameliorate the danger (rising seas, extreme weather events, starvation, war, economic disruption, poisoned oceans and fresh water resources, etc.) and to eliminate the causes (fossil fuel emissions) of AGD. In fact we spend more money on wars to protect our access to fossil fuel resources in the Middle East than we do to address the real threat to all life on this planet, which is being caused by the emissions from burning those very same fossil fuels.

US Defense Department lists climate change as urgent national security threat:

To the military, climate change acts as a threat multiplier, exacerbating threats in already unstable regions of the world. Just as we act aggressively on information from the national security intelligence community, we must also act on the scientific evidence from our nation’s best climate scientists.

2016 US Military spending (roughly $600 Billion) versus Federal Gov't Spending on Climate Change ($20 Billion), a 30:1 ratio and probably an underestimate:

Billions in Tax Deductions granted to fossil fuel polluters for cleaning up their oil spills:

[I]n the U.S., deductions for cleaning up oil spills allows companies to claim the cost as a standard business expense. This provision allowed British oil giant BP Plc to claim $9.9 billion in tax deductions in 2010 following the Deepwater Horizon accident in the Gulf of Mexico, where the company reportedly incurred over $32.2 billion in cleanup costs.

“In 2015, BP reached a final settlement with the US government and five state governments totalling $20.8 billion. However, only $5.5 billion of this is in the form of a non-tax-deductible penalty, and the remainder can be written off by BP,” the report said.

Cost of US Severe Weather events in 2015 exceeded $22.5 Billion:

In 2015, there were 10 weather and climate disaster events with losses exceeding $1 billion each across the United States. These events included a drought event, 2 flooding events, 5 severe storm events, a wildfire event, and a winter storm event. Overall, these events resulted in the deaths of 155 people and had significant economic effects on the areas impacted. The 1980–2015 annual average is 5.2 events (CPI-adjusted); the annual average for the most recent 5 years (2011–2015) is 10.8 events (CPI-adjusted). [...]

In performing these disaster cost assessments these statistics were taken from a wide variety of sources and represent, to the best of our ability, the estimated total costs of these events -- that is, the costs in terms of dollars that would not have been incurred had the event not taken place. Insured and uninsured losses are included in damage estimates. Sources include the National Weather Service, the Federal Emergency Management Agency, U.S. Department of Agriculture, other U.S. government agencies, individual state emergency management agencies, state and regional climate centers, media reports, and insurance industry estimates.
