Overheating hits low-income communities hardest, and because it usually does not bring dramatic television coverage and is widely alerted, people sometimes underestimate its risks.
Supporters of the public early warning system say naming heatwaves can save lives and trigger measures such as opening community cooling stations and requiring people to stay indoors.
This month, Seville, Spain, is preparing to become the first city to start naming a severe heatwave. Five other cities-Los Angeles, Miami, Milwaukee, Kansas City, Missouri and Athens-have begun piloting similar initiatives, using weather data and public health standards to classify heat waves.
They will use three types of systems that organizers want to standardize, and each city's system will be adjusted to its specific climate. For example, Los Angeles's & quot; category & quot; heatwave will look and feel very different from the same title in Milwaukee.
Casey Bowman McLeod, director of the Adrianna Asht Rockefeller Foundation's resilience Center, said: & some of the most unaccustomed places in quot; are the most dangerous, and the center is spearheading efforts to name and classify heatwaves. According to the early warning system launched in six cities around the world, the first category of quot; & quot; is the least serious, and the third category of & quot; & quot; will be the most terrible 10% heat wave of & quot; & quot;. For all three cases, we recommend staying in an air-conditioned room as much as possible. & quot
Kalkstein says that each city that participates in the naming and rating of the heatwave, quot;, has a different formula & quot;, will determine what these categories look like, based in part on their urban structure. Like. There are many brick townhouses in Philadelphia, and their roofs are black tar, which absorbs more heat.
Any designation will have a series of plans, such as prompting city managers to open swimming pools, reducing outdoor sports, turning on emergency heating lines, and staff going door to door to check the elderly and high-risk groups.
Arsht-Rock and its two-year-old extreme Thermal resilience Alliance are urging the National Oceanic and Atmospheric Administration (NOAA) and the World Meteorological Organization to make the naming and ranking of heatwaves a standard practice. NOAA operates the National Weather Service, which so far favours an early warning system but not a naming system.
The National Weather Service says that although it & quot; does not name the heat wave & quot;, it does & quot; appreciate the value of ongoing research and participation to promote our understanding and response to extreme high temperatures and other weather events. & quot; at the same time, California may soon become the first state in the United States to establish an extremely high temperature event warning and quot; ranking & quot; system. The relevant legislation passed unanimously by the state legislature will soon be considered by the state Senate.
The idea of a statewide early warning system stems from a report by the California Insurance Commissioner. The report says: & quot; California on wildfires Red Flag & # 39; warning that the EPA's air quality application and NOAA's naming system for tropical storms and hurricanes can serve as templates for naming and ranking heatwaves. & quot
In July, Arsht-Rock will release forecasts of expected high temperature mortality in 13 cities, as well as new data on the impact of high temperatures on worker productivity.
