Researchers examine how over 3,000 mammal species might migrate and share viruses over the next 50 years if the world warms by 2 degrees Celsius, which recent research shows is possible
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.
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. Previous research has looked at how deforestation and extinction and wildlife trade lead to animal-human disease spread, but there’s less research about how climate change could influence this type of disease transmission, the researchers said at a media briefing Wednesday.
Daniel R. Brooks, a biologist at University of Nebraska State Museum and co-author of the book “The Stockholm Paradigm: Climate Change and Emerging Disease,” said the study acknowledges the threat posed by climate change in terms of increasing risk of infectious diseases. “Of particular note is that the study indicates that these encounters may already be happening with greater frequency and in places near where many people live,” Bernstein said.
