Soil carbon and climate change: from the Jenkinson effect to the compost-bomb instability

Study: Long-term warming equivalent to 10°C per century could be sufficient to trigger compost-bomb instability in drying organic soils Wiley: First generation climate–carbon cycle models suggest that climate change will suppress carbon accumulation in soils, and could even lead to a net loss of global soil carbon over the next century. These model results are qualitatively…

Melting permafrost releases greenhouse gases
