Mega Disasters and World Militaries: How Climate Change is Transforming National Security

Mega disasters, such as Typhoon Haiyan that struck the Philippines in 2013, have expanded world militaries’ roster of duties to include battling the elements. Although militaries in their national jurisdictions have long been helping rescue distraught publics from cataclysmic events, they always have been the last line of defense. Mega disasters of today, however, have catapulted them into the role of first responders. In this role, they are now needed within and beyond national jurisdictions, as disasters-stricken nations increasingly find themselves outmatched by the magnitude of the calamities they face. Deploying an emerging approach that views climate change as a threat to national security, this paper examines how climate-induced mega disasters have had a degenerative impact on global defense establishments, leaving them increasingly inadequate to combat the ever-intensifying ferocity of the elements. The empirical focus of this study is on Typhoon Haiyan, which in 2013 ranked the world’s most potent meteorological event. The paper accounts for Haiyan’s implications for global and national security regimes, particularly the changing role of world militaries.
