Basically...the warmer it gets, the more the microbes decompose stuff in the soil, the more CO2 is released, the warmer it gets. A positive feedback cycle. Dr Kristiina Karhu of the University of Helsinki, and lead author of the paper, said: Because soils store more than twice as much carbon than the atmosphere, changes in rates of decomposition and carbon dioxide release from soil could be very important. Our findings suggest that warming will increase the activity of soil microbes to a greater extent than was previously expected, which could have implications for future rates of climate change.
