Many are taking place silently and unnoticed.In recent years, – thresholds where a small change could push a system into a completely new state – have increasingly become a focus for the climate research community.

Mammals forced to move to cooler climes amid global warming are “already” spreading their viruses further – with “undoubtable” impacts for human health, a new study says. The research, published in , uses modelling to map how climate change could shift the geographic ranges of 3,100 mammals species and the viruses they carry by 2070. It finds that climate change is increasingly driving new encounters between mammal species, raising the risk of novel disease spread. The world’s “biodiversity hotspots” and densely populated parts of Asia and Africa are most likely to be affected.The findings...…Mammals forced to move to cooler climes amid global warming are “already” spreading their viruses further – with “undoubtable” impacts for human health, a new study says.
