为了检验城市高温警戒系统的有效性，对四个北美城市--代顿(美国俄亥俄州)、费城(美国宾夕法尼亚州)、凤凰城(美国亚利桑那州)和多伦多(加拿大安大略省)的降温计划进行了彻底的评估。与这项评估相一致的是，对这些城市大都市地区的居民进行了一项调查，以衡量他们对高温易损性的看法，以及他们对高温警报的了解，以及为帮助减轻高温影响而建议采取的活动。共有908名受访者参与了这项电话调查。一些关键的结果表明，对高温警报的了解几乎是普遍的(90%)，这可能是由于媒体的普遍报道，而不是其他任何方式。尽管人们对这一事件的了解很广泛，但关于该做什么的知识却不太常见。只有大约一半的受访者提到他们改变了自己的行为，尽管关于缓解高温脆弱性的信息五花八门，但大多数受访者表示，他们只是不惜一切代价“避免户外活动”。尽管空调在受访者中几乎无处不在，但超过三分之一的受访者表示，能源成本的经济因素是根据空调开多长时间或是否打开来考虑的。
To examine the efficacy of municipal heat watch warning systems, a thorough evaluation of the heat mitigation plans of four North American cities - Dayton (Ohio, USA), Philadelphia (Pennsylvania, USA), Phoenix (Arizona, USA), and Toronto (Ontario, Canada) - was undertaken. In concert with this evaluation was a survey of residents in the metropolitan areas of these cities that gauged their perception of their own vulnerability to the heat, as well as their knowledge of heat warnings and the activities recommended to be undertaken to help mitigate the effects of the heat. In total, 908 respondents participated in the telephone survey. Some of the key results indicate that knowledge of the heat warning was nearly universal (90%), and likely due to pervasive media coverage more than any other means. Though knowledge of the event was widespread, knowledge of what to do was less common. Only around half of all respondents mentioned that they changed their behavior, and despite the diversity of information available on mitigating heat vulnerability, most respondents stated that they merely "avoided the outdoors" at all costs. Though air conditioning was nearly ubiquitous among respondents, over a third mentioned that economic factors of energy costs were considered in terms of how long or whether the air conditioner was turned on.
