Abstract
The observed changing in the nature of climate-related events and the increase in number and severity of extreme weather events has changedexposure and risk patterns across the globe. In recent years, extreme heat events caused excess mortality and public concerns in many regions of the world (2003/2006 European heat waves, 2007/2010 Asian heat waves, 2006 and most recent 2010-2012 North American heat waves). In the United States, extreme heat events have been consistently reported as the leading cause of weather-related mortality and have attracted widespread attention regarding the critical importance of risk assessment and decoding its components for risk reduction. In order to understand impact potentials both the spatially and temporally varying patterns of heat stress and the multidimensional characteristics of vulnerability have to be considered. A newly developed composite vulnerability index at very high spatial level of detail is matched with a novel heat stress hazard assessment approach for the US National Capital Region. Illustrating actual impact patterns from the 2010 US east coast heat wave the study reveals vulnerability as main driver, generally showing a clear difference between high-risk urban areas and wide areas of low risk in the sub-urban and rural environments. The high spatial granularity of the presented assessment highlights the additional value gained by sub-county analysis as impact root causes are obscured by coarse-level data availability. The study sets a framework for local-level heat stress risk assessment aiming at supporting risk reduction and optimization of resource distribution as well as long-term climate adaptation planning.
