Global warming and planetary health: An open letter to the WHO from scientific and indigenous people urging for paleo-microbiology studies

This article, written by a collective of international researchers and worldwide representatives of indigenous populations, is an open letter to the WHO, based on the latest elements from the scientific literature, and the latest climatological data. It takes stock of the health consequences of global warming, and urges research organizations to take an interest in infectious agents formerly stored in the layers of ground (frozen or not) and now mobilized, then released from a distance. •A collective of researchers and representatives of indigenous peoples is moved by the catastrophic health situation linked to global warming.•The risk of resurgence of ancient infections linked to the recirculation of previously buried geological environments is real.•There is a need for WHO to take up the subject and develop interdisciplinary research programs in this direction.
