- Abstract:
- The climate-security century is here. With global temperatures rising, climate change is poised to massively destabilize the physical environment. This century may well be defined by our ability (or inability) to reduce our collective greenhouse gas emissions. We must also adapt and respond to climate change’s multivariate security impacts. From raging wildfires in Australia and California to melting ice sheets and permafrost in the Arctic, climate change acts as both a threat accelerant and a catalyst for conflict. Climate change is also unlike any other traditional security threat. It accelerates and exacerbates existing environmental stressors—such as sea level rise, extreme weather, drought, and food insecurity—leading to greater instability. Climate change impacts are already taking center stage this century, forcing us to think more broadly about climate change’s relationship with human security and national security. Complicating matters, climate-driven temperature increases do not rise in a neat, uniform fashion around the globe. The pace of climatic change unfolds unevenly and erratically. Some parts of the world—such as the Arctic—are warming at a rate two to three times faster than the rest of the world. Three specific climate-security “hotspots” foreshadow greater destabilization and serve as climate “canaries in a coal mine”—a sneak preview of our climate-destabilized future.
