A 37 year study at the Harvard Forest reveals that soil carbon previously thought to be stable can break down as temperatures rise. This process is driven by shifts in microbial communities that accelerate the decomposition of organic matter, releasing additional CO2 into the atmosphere. These findings suggest a potential climate feedback loop where warming temperatures trigger more soil carbon emissions, further accelerating global warming. Researchers emphasize the need to integrate these long term observations into climate models for more accurate future projections.
