Recent hurricanes Milton and Helene, which wreaked havoc in Florida and North Carolina, serve as a stark reminder of the escalating threat posed by climate change. These devastating weather events, characterized by their significant damage and tragic loss of life, were exacerbated by the effects of global warming. A warmer atmosphere leads to more intense and frequent hurricanes, a grim reality that is becoming increasingly evident.
The Pentagon, not typically associated with environmental concerns, has identified climate change as a serious national security issue. The rise in sea levels, another consequence of global warming, is threatening key Navy bases situated in places like Norfolk and Virginia Beach. This potential inundation of military infrastructure illustrates how climate change can directly impact national defense.
In addition to its direct impact on the environment, climate change is also leading to a global increase in climate refugees. The escalating conflicts in vulnerable regions such as Sudan are fueled by changing weather patterns, which make survival even more challenging in these already unstable regions. Climate change has therefore emerged as a significant factor in geopolitical instability.
With these realities in mind, it is clear that the traditional concept of national security should be expanded to include existential threats like climate change and pandemics. These issues pose significant risks to society, threatening not only our physical safety but also our social and economic stability.
Human-caused global warming, in particular, has increased the likelihood of intense hurricanes. This was evident with the record-hot Gulf of Mexico last month, which intensified Hurricane Helene into a destructive force. Climate change has amplified the rainfall and wind intensity of hurricanes, making severe storms about 2.5 times more likely than in the pre-industrial age.
Evidence points to the fact that the sea surface temperature around Hurricane Milton’s path was significantly increased due to climate change. This rise in temperature caused the hurricane to rapidly escalate to a Category 5 event, the most destructive on the Saffir-Simpson scale.
The destructive impacts of recent hurricanes serve as a stark reminder of the dangers of a warming planet. The urgency with which we need to confront this global crisis cannot be overstated. The continuous cycle of climate change exacerbating natural disasters, which in turn exacerbate climate change, needs to be broken before it’s too late.
