A new study predicts that climate change will cause the spread of thousands of new viruses among many types of animals by 2070. The researchers say that such a spread will likely increase the risk of new diseases transmitted from animals to humans.
The research covered about 3,000 species of mammals and animals including cats, bats, whales, and humans, to name a few. Scientists have created a model to see how these species might migrate and share viruses in the next 50 years if the world’s temperature rose by two degrees Celsius. Recent research has suggested that such a temperature rise is possible.
The team said the model predicted that spread of the virus across species would occur more than 4,000 times among mammals.
Not all viruses will spread to humans or lead to epidemics like COVID-19, the researchers said. However, the study notes that the higher number of viruses across species will increase the risk of them spreading to humans.
The results appeared recently in the publication temper nature.
The study points to two major global crises that could cause the transmission of diseases from animals to humans – climate change and the spread of infectious diseases.
Previous research has examined how deforestation, species disappearance, and the wildlife trade can lead to the spread of disease between humans and animals. There is little research on how climate change affects the spread of this type of disease, the researchers said.
“We don’t talk about the climate much in Context Zoonoses are a term that refers to diseases that can spread from animals to humans, said Colin Carlson, a professor of biology at Georgetown University in Washington, DC. my world Our crises.
Many experts in the field of climate change and infectious diseases agree that global warming is likely to increase the risk of new viruses emerging.
Daniel R. Brooks is a biologist at the Nebraska State Museum and co-author of the book The Stockholm Model: Climate Change and Emerging Diseases. Tell Associated Press The latest study supports the idea that new disease threats can be linked to climate change.
“This one contribution Extremely reservation Estimate “the potential for the spread of new infectious diseases caused by climate change,” Brooks said.
Aaron Bernstein, MD, is the current director of the Center for Climate, Health, and Global Environment at Harvard University’s T.H. Chan School of Public Health. He said the study confirms long-standing doubts about the effects that global warming could have on creating new infectious diseases.
He noted that the study indicates that such cases “may indeed occur with a greater number.” to hesitate And in places close to where a lot of people live,” Bernstein said.
Study co-author Gregory Alberi is a disease expert at Georgetown University. He told the AP that because climate-induced infectious diseases have likely already arisen, the world must do more to recognize and prepare for them.
“It can’t be prevented, even in the best case scenario, from climate change scenariosAlberi said.
