DOI: 10.1038/s41586-026-10413-x Every year, millions suffer, and thousands lose their lives to infections that were once easily treatable with the right dose of medication. The drugs are the same; human physiology is the same; the only difference is that microbes, such as bacteria, viruses, and fungi, have now developed resistance to drugs designed to kill them. This phenomenon, known as antimicrobial resistance, is rapidly rising, ringing sirens for emergency action across the globe. A new 11-year study found that, in addition to the misuse and overuse of antibiotics, long-term climate warming can also increase the abundance of antibiotic resistance genes (ARGs) in grassland soils by nearly 24%. Higher temperatures favor the growth of Actinomycetota —a group of mostly Gram-positive bacteria that naturally carry many resistance genes.…
