Across southern Europe, increasingly extreme heat, wildfire and intense rainfall are forcing planners to consider how one event can alter the risk of the next. Portugal's exceptionally wet winter and another summer of wildfire risk are an example of this. As a professor of architecture and climate change adaptation who has been following the cyclical nature of weather extremes in the Pinhal Interior region since the deadly 2017 fires, I explain why prevention must connect forests, settlements, slopes and waterways.
