In a report to the US Congress, the Department of Defense identifies climate change “as a present security threat, not strictly a long-term threat.” Climate change poses a very real threat to national and global security in its capacity to cause “natural disasters, refugee flows, and conflicts over basic resources such as food and water.” Citing an Intergovernmental Panel on Climate Change (IPCC) report, DoD and its Geographic Combatant Commands state, “climate change will have the greatest impact on areas and environments already prone to instability.” I find this to be a critical report that hopefully will force US policy makers to recognize the immediate threat that climate change poses to US national security. DoD makes responding to climate change a top priority and therefore makes climate change a much more urgent issue.
DoD and its GCCs have certainly done a fair amount of research on the potential impact climate change will have on their own Areas of Responsibility, but how useful and effective do you think the steps DoD says it is taking to address climate change are? What must the rest of the US government and the international community do to respond to climate change?
Climate change is clearly an international problem. What plans can you find in this report that include international cooperation? Is there potential here for countries to free ride efforts made by the US and other countries with large security apparatuses, the same sort of free riding seen as a result of faulty international agreements such as the Kyoto Protocol? DoD mentions situations where the US can and should to respond to climate change, but there is the possibility that these countries could come to rely too much on US support and so DoD could become overextended. — Mitch
