Heat Waves Should Be Named And Ranked Says Newly Formed Heat Resilience Group

The Extreme Heat Resilience Alliance, a recently formed group of experts, is suggesting that heat waves should be named, similarly to how hurricanes are named, and ranked by severity as the first step towards increasing heat wave visibility.

Heat waves were the deadliest weather-related disaster in the US between 1986 and 2019 and were responsible for 4,257 deaths. The next deadliest weather-related disaster in the US was floods responsible for 2,907 deaths over the same time period.  The greatest challenge in making heat waves visible is that they don’t produce the same amount of physical damage that flooding or other severe weather like tornadoes do.  However, by naming and ranking the severity of heat waves the Alliance hopes that communities will be able to better prepare for extreme heat events.

Unfortunately, heat waves are expected to increase in frequency and will be affecting more than 3.5 billion people globally by 2050.  It is also expected that the urban poor and the disadvantaged will weather the worst of the effects caused by heat waves because of community vulnerability.

The Alliance’s formation is timely as just yesterday Death Valley, CA saw the hottest temperature on Earth since at least 1913 according to NPR.  As heat waves become more frequent and more intense, a failure to prepare communities for extreme heat events like the European heat wave of 2003 will result in the loss of human lives.
