Reframing climate security: The “planetary” as policy context

• Conventional climate security discussions fail to grapple with earth system science. • Climate security should be reformulated in terms of the current planetary context. • Adaptability, sustainable habitats and fossil fuel control are the key elements needed. • Major derailment risks loom if urgent climate change action isn’t undertaken. Much of the discussion under the label of “climate security” focuses on potential conflicts and disruptions in peripheral locations in the global south putatively triggered by climate change. If, however the analysis starts with climate, and the earth system as the point of departure for analysis, then things look very different. The speed and scale of climate disruptions is accelerating. Earth system science suggests that urgent action is needed to deal with climate change; waiting too long may make the issue impossible to address. Framing matters in terms of a planetary condition and focusing on climate rather than national security as the starting point for analysis suggests very different policy priorities. Reframing climate security to grapple with the planetary condition requires policies that first, facilitate adaptation, second work to make sustainable habitats for humanity and third, work to drastically constrain the use of fossil fuels urgently. Here, proposals for fossil fuel non-proliferation treaties and similar measures analogous with earlier arms control agreements. This provides the security sector with a much-needed direct engagement with the causes of climate change and its resultant disruptions while simultaneously reframing climate as a matter of planetary rather than national security. Tackling climate change is a matter of urgency, and failure to so effectively in the short run my derail needed efforts later, simply because the resources to do so are no longer available.
