Soil warming experiment reveals stable carbon breakdown after 37 years
This digest was compiled by AI from multiple sources — links to the originals are below.
The world's longest-running soil warming experiment, spanning 37 years, has found that warming causes microbes to break down stable soil carbon previously thought protected. This releases additional carbon dioxide into the atmosphere, potentially accelerating global warming.
The Experiment
Researchers conducted the world's longest-running soil warming experiment over 37 years. They found that warming causes microbes to break down stable soil carbon, releasing extra CO2. This challenges previous assumptions that such carbon was largely protected from decomposition.
Climate Implications
The released carbon dioxide could accelerate global warming, creating a feedback loop. The study highlights a hidden climate threat that may amplify existing warming trends. Further research is needed to quantify the global impact.
What's Next
Scientists plan to expand monitoring to other ecosystems to assess the broader effect. It remains unclear how much additional carbon could be released globally and whether mitigation strategies can address this feedback.
