1. The website provides scientific data compiled and illustrated in understandable graphics. Important to communicate the urgency to the public. 2. It has been impossible to find temperature data of Valdivia centre and surrounding rural areas. But I can share my perceptual experiences which I relate to UHI - particularly the canopy layer heat island: Walking at night from the city centre home (just 2,5km from the centre but with suburban character), I can note a drop in temperature - especially in summer nights. I guess here the urban geometry is mostly responsible for the UHI effect. The centre has mainly narrow street canyons while the suburban area is open - composed of single-family houses with gardens, open wetlands, and large green areas. That suburban geometry allows a better ventilation. The presence of vegetation and wetlands adds to a cooler environment by shading and evaporation. 3. Conduct thorough studies to record + monitor temperature differences. Increase the number of trees in the centre and support green roofs and facades. Protect existing urban green areas and wetlands. 4. UHI is not yet a big topic in southern Chile. Ongoing study analyzes UHI effect in southern Chile to propose mitigation measures.
