The UN Secretary-General's Call to Action on Extreme Heat brings together the diverse expertise and perspectives of ten specialized UN entities (FAO, ILO, OCHA, UNDRR, UNEP, UNESCO, UN-Habitat, UNICEF, WHO, WMO) in a first-of-its-kind joint product, underscoring the multi-sectoral impacts of extreme heat. In support of the Call to Action, the Global Heat Health Information Network launched a set of Heat Action profiles, mapping heat-related work across 16 UN and international organizations.
