Heat-Related Health Risks
185 The relationship between human health and stressful weather is a complex medical, social, and environmental issue (Figure 1). Futureclimate scenarios suggest that higher global mean temperatures could result in marked changes in the frequency of temperature extremes (1). Software developed by the National Oceanic and Atmospheric Administration (2) can be used to estimate changes in the prob...
متن کاملClimate Change Risks Facing Urban Areas
technological advancement has led to a clearer understanding of future risks and impacts. With increasing urbanization, understanding the impacts of climate change upon the urban environment will become ever more important. Evidence is mounting that climate change presents unique challenges for urban areas and their growing populations. Where urban areas grow rapidly without regard to current a...
متن کاملMapping Manchester’s urban heat island
An urban heat island (UHI) is a phenomenon whereby urban areas experience elevated temperatures relative to the surrounding rural hinterland. This thermal contrast is brought about by anthropogenic modification of the environment. For example, there is little bare earth and vegetation in urban areas. This means that less energy is used in evaporating water, less of the Sun’s energy is reflected...
متن کاملUrban-Hazard Risk Analysis: Mapping of Heat-Related Risks in the Elderly in Major Italian Cities
BACKGROUND Short-term impacts of high temperatures on the elderly are well known. Even though Italy has the highest proportion of elderly citizens in Europe, there is a lack of information on spatial heat-related elderly risks. OBJECTIVES Development of high-resolution, heat-related urban risk maps regarding the elderly population (≥ 65). METHODS A long time-series (2001-2013) of remote sen...
متن کاملSpectral resolution requirements for mapping urban areas
This study evaluated how spectral resolution of high-spatial resolution optical remote sensing data influences detailed mapping of urban land cover. A comprehensive regional spectral library and low altitude data from the Airborne Visible/Infrared Imaging Spectrometer (AVIRIS) were used to characterize the spectral properties of urban land cover. The Bhattacharyya distance was applied as a meas...
