- Vernon Spear's near-fatal infection from Vibrio vulnificus after checking crab traps in Maryland highlights the bacteria's flesh-eating effects, requiring emergency surgery.
- Climate change is causing Vibrio vulnificus to become more abundant in warmer waters, with infections now occurring farther north and increasing in frequency.
- Microorganisms, including bacteria and fungi, are adapting rapidly to warmer temperatures, potentially overcoming thermal barriers and posing new threats to humans.
- Fungal diseases like Candida auris have emerged with heat tolerance, spreading globally and showing resistance to treatments, illustrating microbial evolution in response to climate shifts.
- Melting glaciers and thawing permafrost release dormant microbes and viruses, altering ecosystems and risking horizontal gene transfer of resistance traits.
- Scientists are exploring microbial interventions to mitigate climate impacts, such as using microbes to protect corals or clean up pollutants, while efforts to preserve microbial biodiversity are underway.
