Climate crisis is accelerating antibiotic resistance across world, study says

A multinational study published in Lancet Planetary Health links climate change to a 10% rise in salmonella antibiotic resistance genes between 1940 and 2023. Researchers analyzed 480,000 salmonella samples from 139 countries, finding that rising temperatures and altered rainfall patterns accelerate bacterial adaptation to antibiotics. The Middle East, North Africa, and South Asia showed the strongest climate-associated increases.
