Hurricane 'Stan'—or maybe it was 'Tara,' I always get those names mixed up—came barreling through my coastal town last summer. It wasn't the most powerful hurricane in the world, but it was powerful enough. Powerful enough to flood my basement, powerful enough to knock out power for days, powerful enough to make me really think about the implications of climate change. Before, it felt like this distant, abstract problem. It felt.intimately personal, afterwards. The soggy carpet and smell of mildew? Yeah, that was a harsh wake-up call. And that's when it hit me: climate change isn't just an environmental issue—it's a national security threat of the first order.

FOOD INSECURITY: A MATTER OF NATIONAL SECURITY
Think about it: Climate change sparks extreme weather events, destroying harvests. Crops fail. Supply chains are disrupted. Food prices skyrocket. Suddenly, you have widespread food insecurity—and when people are hungry, they are desperate. Desperation breeds instability, unrest, and even conflict. We're already seeing this in different parts of the world, but if we do not take this seriously, it is going to be a far bigger problem very quickly. My uncle is a farmer in Iowa, and last year he was telling me how crazy the weather has been. He's worried about the future of his farm, and so am I.

Mass Migration and Resource Conflicts
Rising sea levels and intensifying droughts will make people move away from their residences. This could create mass migrations that will put strain on the existing resources and infrastructure. Even resource wars—say, for water—may emerge. Imagine the millions of climate refugees in an instant needing food, shelter, and health care. It's a recipe for chaos. I remember reading an article on climate refugees in Bangladesh. How frightening that is. No laughing matter. A storm that we need to start preparing for—proactively, with strategy in place.

Infrastructure Vulnerability Our infrastructure—infrastructure, power grids, transportation networks, water systems—wasn't designed to be resilient to the type of extreme weather events that we're experiencing at a greater frequency now. A major storm, prolonged drought, or destructive wildfire can shut down key services, weakening communities, and it will touch on our capacity to act when there are other national emergencies. Not if, but when more extensive failures in our infrastructure will occur. We have to invest in climate-resilient infrastructure. We have to. It's a national security issue.

Climate change is not a problem that is contained within national borders; it's a global crisis that can destabilize entire regions, creating power vacuums that terrorist organizations can then fill. Think about it: resource scarcity, mass migrations, and economic hardship—all of these exacerbated by climate change can provide fertile ground for extremism. It's scary, but the facts bear this out. We need a global plan of action on climate change—comprehensive—for the sake of the environment, certainly, but also very much for national security.

Climate change does pose a serious threat to national security. It is not a distant threat; it is here, happening, and already affecting our lives. But together, governments, businesses, and individuals can work to reduce the risks and build a more secure and sustainable future. So let's get started, and let's be part of the solution. The time for complacency is past. Let's face this together.
