“…Consequently, debates among policy makers are focusing around the issue of how to maintain urban regions as attractive, productive and safe places in the future. These debates evolve in a direct relation with the governance of heat risks, an emerging policy field in Europe in the wake of the 2003 and 2006 heat waves which resulted in peaks in morbidity and mortality, and a sharp controversy across the continent (Boezeman, Ganzevoort, Lier & Louwers, 2014;Kovats & Hajat, 2008;Lass, Haas, Hinkel & Jaeger, 2011). The central question in these debates is whether and how urban warming should be a legitimate object for governance, and, if so, whether it should be a matter of social cohesion policy (Klinenberg, 2003;Poumadère, Mays, Le Mer & Blong, 2005), town planning (Hebbert & Mackillop, 2013), public health (Kovats & Hajat, 2008), or any other field of collective organisation.…”
