In a report released on Monday and on the heels of the first debate in the United Nations Security Council on the issue, 11 retired U.S. military leaders assert that climate change raises risks and tensions in the world’s most volatile areas, and the U.S. needs to start planning and cooperating with other nations to mitigate and respond to those risks. From the Associated Press:

“The report warns that in the next 30 to 40 years there will be wars over water and increased instability from hunger, worsening diseases, rising sea levels and global warming-induced refugees. ‘The chaos that results can be an incubator of civil strife, genocide and the growth of terrorism,’ the 35-page report predicts.

‘Climate change exacerbates already unstable situations,’ former U.S. Army Chief of Staff Gordon Sullivan said. ‘Everybody needs to start paying attention to what's going on. I don't think this is a particularly hard sell in the Pentagon. … We're paying attention to what those security implications are.’

Gen. Anthony Zinni, President Bush's former Middle East envoy, said in the report: ‘It's not hard to make the connection between climate change and instability, or climate change and terrorism.’”

The leaders urged the U.S. to take action now, without waiting for a total certainty on global warming’s impacts. Extreme weather like drought, flooding, rising sea levels, and shifts in habitat for plant and wildlife are some of the expected consequences. Any of these could prompt U.S. military involvement; for example, the U.S. and Europe may have to accept environmental refugees from Latin America and Africa as drought increases and food production declines. Climate change impacts could also make life more difficult in unstable locales like parts of Africa, Asia, and the Middle East, perhaps driving the U.S. more frequently to provide stability before conditions are exploited by extremists.

Although the U.S. is the planet’s biggest emitter of global warming pollution, the report stressed that it does need to develop strong partnerships with other nations like China and India, who will be contributing significantly to the global economy and to its emissions.

The report was published by the non-partisan CNA Corporation think tank.
