A new university study has destroyed the idea that soil carbon sequestration will be the silver bullet to reduce Australia's greenhouse gas emissions. In fact, a warming climate will mean that the soil's ability to retain soil carbon will be diminished over time, making soil carbon markets a "dangerous" place for farmers, a leading independent scientist said.

The University of Melbourne and University of Tasmania study has found that within 30 years, soil organic carbon sequestration rates will have "declined by 45-133 per cent, heralding dire ramifications for nations aspiring to capitalise on enhanced soil carbon sequestration as an avenue for emissions mitigation".

University of Tasmania's systems modelling team leader Associate Professor Matthew Harrison said today findings of a multidisciplinary research report-called Carbon, cash, cattle and the climate crisis-showed that as the climate warmed, the speed at which carbon was respired from soil also increased.
