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…

Getting rich off global warming

The permafrost carbon feedback loop

THE world is on the cusp of a “tipping point” into dangerous climate change, according to new data gathered by scientists measuring methane leaking from the Arctic permafrost and a report presented to the United Nations on Tuesday. “The permafrost carbon feedback is irreversible on human time scales,” says the report, Policy Implications of Warming…
