Climate security

Climate security describes serious threats to the security and prosperity of countries, due to climate warming, and climate actions to adapt and mitigate impacts.

Climate change has been identified as a threat multiplier, which can exacerbate existing threats. A 2013 meta-analysis of 60 previous peer-reviewed studies, and 45 data sets concluded that, "climate change intensifies natural resource stresses in a way that can increase the likelihood of livelihood devastation, state fragility, human displacement, and mass death." The 2014 report, by the CNA Military Advisory Board, "National Security and the Accelerating Risks of Climate Change" re-examined the impact of climate change on U.S. national security. The report concluded that climate change is a growing security threat.

A 2015 report published by the White House found that climate change puts coastal areas at risk, that a changing Arctic poses risks to other parts of the country, risk for infrastructure, and increases demands on military resources. The NATO stated in 2015 that climate change is significant security threat and ‘Its Bite Is Already Being Felt’.

The 2016 Global Risks Report by the World Economic Forum, concluded that forced migration and climate change are the biggest risks for the global economy.

In 2016, Director of National Intelligence James Clapper noted:

Unpredictable instability has become the “new normal,” and this trend will continue for the foreseeable future…Extreme weather, climate change, environmental degradation, rising demand for food and water, poor policy decisions and inadequate infrastructure will magnify this instability.

The Global Security Defense Index on climate change evaluates the extents of governments in considering climate change to be a national security issue.

A Pentagon report has pointed out how climate denial threatens national security.
