A new report warns that conflicts over water and food could intensify as the climate changes.
For years, the debate over global warming has focused on the three big "E's": environment, energy, and economic impact. This week it officially entered the realm of national security threats and avoiding wars as well.
A platoon of retired US generals and admirals warned that global warming "presents significant national security challenges to the United States." The United Nations Security Council held its first ever debate on the impact of climate change on conflicts. And in Congress, a bipartisan bill would require a National Intelligence Estimate by all federal intelligence agencies to assess the security threats posed by global climate change.
Many experts view climate change as a "threat multiplier" that intensifies instability around the world by worsening water shortages, food insecurity, disease, and flooding that lead to forced migration. That's the thrust of a 35-page report (PDF) by 11 admirals and generals this week issued by the Alexandria, Va.-based national security think tank The CNA Corporation. The study, titled National Security and the Threat of Climate Change, predicts:
"We will pay for this one way or another," retired Marine Gen. Anthony Zinni, former commander of American forces in the Middle East and one of the report's authors, told the Los Angeles Times. "We will pay to reduce greenhouse gas emissions today … or we'll pay the price later in military terms. And that will involve human lives."
