HOW WARMING IS SHIFTING MICROBIAL WORLDS.

The article focuses on how climate change is altering microbial communities in various ecosystems and the implications of these changes for global carbon cycling and ecosystem health. Research at sites like Harvard Forest in Massachusetts and the Kessler Atmospheric and Ecological Field Station (KAEFS) in Oklahoma uses experimental warming to study shifts in soil bacteria, fungi, and viruses, revealing that rising temperatures and changing precipitation patterns affect microbial diversity, function, and carbon emissions. These microbial changes can influence greenhouse gas fluxes, nutrient cycling, and plant health, with potential feedbacks on climate change. Scientists are also exploring microbial and viral roles in mitigating climate impacts, such as using probiotics to protect coral reefs and leveraging viruses to reduce nitrogen pollution, though scaling such interventions remains challenging. Overall, microbes are integral to Earth's climate system, and understanding their responses to warming is critical for predicting and managing future ecosystem changes. [Extracted from the article]
