Association of mortality with high temperatures in a temperate climate: England and Wales

It is well known that high ambient temperatures are associated with increased mortality, even in temperate climates, but some important details are unclear. In particular, how heat-mortality associations (for example, slopes and thresholds) vary by climate has previously been considered only qualitatively.An ecological time-series regression analysis of daily counts of all-cause mortality and ambient temperature in summers between 1993 and 2006...
