Climate change will result in thousands of new viruses spread among animal species by 2070 — and that’s likely to increase the risk of emerging infectious diseases jumping from animals to humans, according to a new study.
This is especially true for Africa and Asia, continents that have been hotspots for deadly disease spread from humans to animals or vice versa over the last several decades, including the flu, HIV, Ebola and coronavirus.
Researchers, who published their findings Thursday in the journal Nature, used a model to examine how over 3,000 mammal species might migrate and and share viruses over the next 50 years if the world warms by 2 degrees Celsius (3.6 degrees Fahrenheit), which recent research shows is possible.
They found that cross-species virus spread will happen over 4,000 times among mammals alone. Birds and marine animals weren’t included in the study.
Jaron Browne, organizing director of the climate justice group Grassroots Global Justice Alliance, said the study highlights climate injustices experienced by people living in African and Asian nations.
“African and Asian nations face the greatest threat of increased virus exposure, once again illustrating how those on the frontlines of the crisis have very often done the least to create climate change,” Browne said.
