The risks go beyond the economy and public health. Extreme heat is also emerging as a national security concern. It threatens the physical readiness of soldiers, weakens military installation infrastructure and complicates logistics and supply chains critical to defense operations. The Department of Defense has begun incorporating heat-related stressors into its strategic planning because of the compounding effects on personnel, equipment and mission reliability, especially in rural and remote regions. Like other sectors, the military isn’t waiting for political consensus on climate change. It’s adapting to the effects that are already here.

As the costs from extreme heat mount, there is growing interest from industries and lawmakers to come up with new solutions. Congress recently formed a bipartisan Extreme Heat Caucus — proof that the issue is gaining recognition across the aisle. The focus is on responding to worker injuries, economic losses and public safety risks. That’s a promising sign that heat can unite lawmakers on urgently needed nonpartisan solutions.

Imagine if our approach to heat mirrored how we prepare for hurricanes — anticipating its damage, issuing targeted alerts and deploying protective infrastructure, such as cooling centers, shaded transit stops and reflective roofing materials. A new approach should also include better emergency response systems that prioritize vulnerable populations.

Extreme heat is not a niche environmental issue. It determines whether construction crews can safely finish a job, whether school buildings without adequate air-conditioning can stay open and whether crops make it to market or wither in the field. If we get serious about heat, we don’t just weather the summer — we will protect workers, safeguard infrastructure and strengthen the systems that communities rely upon every day, building a more resilient economy for everyone.
