Silent Killer: How Cities Are Bracing For More Heat

The Rising Cost of Extreme Heat

Extreme heat is now the leading cause of weather-related deaths in the United States, surpassing hurricanes, floods, and tornadoes combined.

The number of heat-related deaths is increasing due to extreme heat events becoming more frequent and more intense. Rising temperatures cause heat stress, dehydration, and other health problems, especially among vulnerable populations such as the elderly, children, and those with pre-existing health conditions.

The Health Impacts of Heat

Heat Stress

Heat stress occurs when the body is unable to cool itself sufficiently. This can lead to a range of symptoms, including:

• Cramps
• Nausea
• Headaches

Dehydration

Dehydration occurs when the body loses more fluid than it takes in. Symptoms of dehydration include:

• Thirst
• Dry mouth
• Fatigue

Heatstroke

Heatstroke is a life-threatening condition that occurs when the body's temperature rises rapidly. Symptoms of heatstroke include:

• Confusion
• Convulsions
• Loss of consciousness

Preparing for Extreme Heat

Cities are taking a number of steps to prepare for the rising threat of extreme heat, including:

Expanding Cooling Centers

Cooling centers are places where people can go to cool down and escape the heat. Cities are expanding the number of cooling centers and making them more accessible to vulnerable populations.

Increasing Tree Cover

Trees provide shade and help to cool the air. Cities are planting more trees in parks, along streets, and in other public spaces.

Promoting Heat-Resilient Buildings

Cities are adopting building codes that require new buildings to be more heat-resistant. These codes include measures such as installing reflective roofs and using heat-resistant materials.

Educating the Public

Cities are educating the public about the dangers of extreme heat and how to stay safe. This includes providing information on how to recognize and treat heat-related illnesses.
