What is the urban heat island effect?
The urban heat island effect occurs when cities experience higher temperatures than surrounding rural areas due to the concentration of buildings, asphalt, and other heat-absorbing surfaces.

Extreme Heat Across the US in Summer 2025: What to Expect and How to Prepare
The summer of 2025 is predicted to bring extreme heat across the United States, exacerbating existing concerns about climate change and the potential impacts of governmental cuts to essential agencies. With record-breaking temperatures alre...
Key Insights
- **Record-Breaking Temperatures:** Many cities are experiencing an increase in the number of days with a heat index above 90 degrees. In 2024, Albuquerque, New Mexico, saw 77 days with a heat index over 90, up from 52 days in 2022. Why this matters: Prolonged exposure to high heat indexes can lead to fatigue, heatstroke, and even death, particularly for vulnerable populations.
- **Understaffed Agencies:** Cuts to federal science agencies, like NOAA, have resulted in reduced staff and services, hindering the ability to predict, prepare for, and respond to heat emergencies. Why this matters: Effective disaster response and public outreach are compromised, leaving communities more vulnerable.
- **Urban Heat Island Effect:** Cities are significantly warmer than surrounding areas due to dense buildings and asphalt, which absorb and retain heat. For example, Houston neighborhoods can vary by as much as 14 degrees Fahrenheit. Why this matters: Urban residents face disproportionately higher temperatures, necessitating measures like increased tree canopies to provide cooling and shade.
- **Vulnerable Populations at Risk:** Older adults, children, outdoor workers, migrants, and those in under-cooled buildings are at higher risk of heat-related incidents. Why this matters: Targeted interventions and protections are necessary to safeguard these groups from the worst impacts of extreme heat.
In-Depth Analysis
Extreme heat is becoming a pervasive issue across the United States, driven by climate change and exacerbated by infrastructure and policy challenges. A USA TODAY analysis found that most major cities have experienced an increase in days with a heat index of 90 degrees or higher since 1985. This trend is particularly acute in the South, Southwest, and Southeast.
**How to Prepare:**
- **Stay Informed:** Monitor local weather forecasts and heat advisories from the National Weather Service&ref=yanuki.com.
- **Hydration:** Drink plenty of water throughout the day, even if you don't feel thirsty.
- **Seek Cooling:** Spend time in air-conditioned environments, such as cooling centers, libraries, or shopping malls. If your home lacks adequate cooling, consider visiting a friend or family member who has air conditioning.
- **Limit Outdoor Activities:** Avoid strenuous activities during the hottest parts of the day. If you must be outside, wear light-colored, loose-fitting clothing and a wide-brimmed hat.
- **Check on Others:** Regularly check on vulnerable friends, family, and neighbors, especially those without air conditioning.
**Who This Affects Most:**
- **Low-Income Communities:** Often lack access to air conditioning and may live in areas with fewer trees and green spaces.
- **Outdoor Workers:** Construction workers, agricultural workers, and others who work outdoors are at high risk of heatstroke and other heat-related illnesses.
- **People with Chronic Illnesses:** Conditions like heart disease, diabetes, and respiratory illnesses can be exacerbated by extreme heat.
Cities are taking steps to mitigate the impact of extreme heat. New York City, for example, aims to achieve a 30% tree canopy cover, while Austin plans for 50%. These efforts help to reduce the urban heat island effect and provide much-needed shade.
Local regulations are also being implemented to protect vulnerable populations. Albuquerque requires rental properties to have cooling systems, and states like New York and Oregon are adding workplace protections for employees during high temperatures.
FAQ
What is a heat index?
The heat index is a measure of how hot it feels when temperature and humidity are combined. It is used to assess the risk of heat-related illnesses.
What are some signs of heatstroke?
Symptoms of heatstroke can include high body temperature, confusion, rapid pulse, and loss of consciousness. It is a medical emergency and requires immediate attention.
Takeaways
- Extreme heat is an increasing threat across the US, driven by climate change.
- Reduced funding for federal science agencies is hampering efforts to prepare for and respond to heat emergencies.
- Vulnerable populations, including low-income communities and outdoor workers, are disproportionately affected.
- Local actions, such as planting trees and implementing cooling regulations, are crucial for mitigating the impact of extreme heat.
