Extreme heat is a threat that often goes unnoticed until it’s too late. As winter grips many parts of the country in a deep freeze, it’s easy to forget about the dangers of extreme heat. However, heat is actually the deadliest weather-related hazard in the United States, claiming more lives than hurricanes, floods, and tornadoes combined. The toll of heat-related illnesses and deaths is staggering, with over 70,000 emergency room visits and 10,000 hospitalizations occurring every year.
One of the most alarming aspects of heat-related deaths is the disproportionate impact on Black and Hispanic Americans. This reflects long-standing inequities in housing, infrastructure, and working conditions. Despite the clear and present danger that extreme heat poses, attention to this issue tends to fade as temperatures drop in the fall. Public budgets shift, emergency plans wind down, and research funding gets reallocated.
The Trump Administration’s proposed cuts to science funding have only exacerbated this problem. The 2026 budget proposal includes double-digit cuts to important research programs, weakening early-warning systems, heat-risk forecasting, and research that guides cities on how to mitigate the effects of extreme heat. Without adequate funding and research, we are essentially flying blind into the next heatwave crisis.
However, some cities are taking proactive steps to prepare for extreme heat. Projects that focus on cooling infrastructure, such as planting trees, using reflective materials, and creating shade, are proving to be effective and low-cost solutions. These projects treat cooling as shared infrastructure rather than a household luxury, benefiting the community as a whole.
Unfortunately, some cities are hindered in their efforts to combat extreme heat due to state preemption laws that restrict their ability to implement necessary measures. Despite these challenges, there are steps that communities and cities can take now to prepare for extreme heat. Planning cooling infrastructure, retrofitting homes, preserving scientific capacity, and prioritizing equity in heat mitigation efforts are all crucial steps in saving lives and preventing heat-related illnesses.
The key to addressing the threat of extreme heat is to treat it as a year-round issue, not just a seasonal one. By taking proactive measures now, cities can better prepare for the deadliest heatwaves before they strike. As climate patterns continue to shift, it’s essential to act now to prevent future heat-related tragedies.
