Here, the public healthcare service carries the residual health risk of exposure to heat. Unfortunately, coordination between public authorities and the private sector is also often lacking in planning and implementing national climate policies. In a Nordic study comparing national climate and tourism strategies, Landauer found that important details, about how snow-based tourism can adapt to shifting seasons, for example, were absent from the national climate strategies. The same was true the other way round: tourism strategies did not state how the sector could implement climate adaptation actions. “There was hardly any mention of one in the other,” explained Landauer. “There must be more collaboration in order to build coherent and effective strategies across scales and sectors.” These concrete policy and action recommendations, made through evidence- based understanding of how sectors, countries, and individuals’ actions affect each other, are essential for humanity to adapt to our changing climate.
