"Permafrost Melting: Reviving Ancient Pathogens Poses Unpredictable Threats"

Melting permafrost due to global warming is releasing ancient viruses that have been preserved for tens of thousands of years. A recent study modeled the interactions between an ancient virus and modern bacteria to assess the potential impact on the ecosystem. While most invading viruses had little effect, in 1.1% of simulations, an invasive virus had a substantial impact, leading to a drop in biodiversity by 32%. Although the risk may seem low, the sheer number of potential exposures is staggering. However, the least populated places on Earth are covered with permafrost, reducing the risk of widespread infection.
