Abstract:	As a result of ongoing global warming, approximately 30% of the world's population lives in areas where the temperature reaches the death risk threshold at least 20 days a year. The distribution of heat and vulnerability, however, varies in a city; where mitigation actions should begin is a simple question that must be answered. Therefore, it is important to identify hotspots and provide a concrete foundation for the following decision-making process that can be used to integrate urban risk management systems. This paper critically reviewed previous studies from 2006 to 2018 on this subject with the following three main research objectives: (1) What are the definitions and connotations regarding the current discussions on "hotspots"? (2) What are the emerging approaches used to define the threshold, intensity and other properties of hotspots according to their different connotations? (3) Where are the gaps between hotspot recognition and urban heat-related risk management? The results indicate that the concepts, especially related to threshold detection methods, are overcomplicated and vague, suggesting the need for further communication among disciplines.
