Climate change could unlock new microbes and increase heat-related deaths

Climate change could unlock new microbes and increase heat-related deaths, Science Daily, January 22, 2020, Source: Johns Hopkins Medicine

Summary:
Scientists warn that global climate change is likely to unlock dangerous new microbes, as well as threaten humans’ ability to regulate body temperature…..
Ahima, director of Johns Hopkins’ Division of Endocrinology, Diabetes and Metabolism, wrote in the journal that “global warming threatens human thermoregulation and survival.”  ……
Casadevall’s article explores “the specter of new infectious diseases” as a result of the changing climate.

“Given that microbes can adapt to higher temperatures,” writes the professor of molecular microbiology and immunology, and infectious diseases, at Johns Hopkins’ schools of medicine and public health, “there is concern that global warming will select for microbes with higher heat tolerance that can defeat our endothermy defenses and bring new infectious diseases.”

Endothermy allows humans and other warm-blooded mammals to maintain high temperatures that can protect against infectious diseases by inhibiting many types of microbes.

Casadevall cites a particular climate threat from the fungal kingdom.

“We have proposed that global warming will lead many fungal species to adapt to higher temperatures,” he writes, “and some with pathogenic potential for humans will break through the defensive barrier provided by endothermy.”….

In all four JCI “Viewpoint” articles, long-term strategies are urged to reduce greenhouse gas emissions and slow the trend of rising temperatures. ….https://www.sciencedaily.com/releases/2020/01/200122122105.htm
