The need for health equitable climate adaptation policies in Northern Europe.

Socioeconomic conditions remain an important factor in determining health outcomes in Northern Europe. In this commentary, we argue for evidence-based temperature-related climate adaptation policies in Northern Europe that account for disparities in socioeconomic conditions and aim at universal health coverage. We highlight the role of spatial and occupational disparities in urban areas that can be important factors in increased physical and mental health impacts related to heat and cold. We further highlight how these factors interplay with exposure to air pollution and access to green areas and worsen health conditions. Adaptation to changing climatic conditions requires both physiological acclimatization and behavioral adaptation, both of which are difficult to assess for socioeconomically deprived communities. We argue for more equitable climate adaptation strategies that include i) better integration of health in climate change adaptation plans; ii) building climate resilient communities, and iii) integrated surveillance and health systems. These actions could be vital in spearheading research in new cross-cutting areas like climate change, migration, and health.
