Abstract

This thesis analyses heat health risk spatially in Birmingham (UK) via a combination of remote sensing and GIS techniques, including urban influences which are not generally considered in heat risk assessments or climate change projections. The world’s urban population is growing rapidly, and the risk of extreme heat to human health has been highlighted by recent events such as the 2003 heatwave in Europe, where mortality rates significantly increased. This thesis presents a methodology using satellite data to quantify the surface urban heat island of Birmingham at 1 km resolution, with results showing extreme events are much warmer (\(\sim\)5°C) than average conditions (\(\sim\)2°C). This urban heat island data is combined with social data in a spatial risk assessment, illustrating that many vulnerable people live in areas of increased heat risk. A custom collection of ground based sensors is utilised to investigate the relationship between surface and air temperatures, finding air temperatures are warmer than LST measurements at night. Then UK Climate Projections 2009 are used to explore the influence of the urban heat island on climate projections in Birmingham, showing that changes could be large (90% increase in minimum temperature under 2080s extreme scenarios).
