Our findings suggest the soil part of the equation is scarier than we had thought. The consequence is that there is more urgency about doing something.
Microbes in the soil are more active at warmer temperatures. As temperatures rise, the turnover of soil carbon goes up.
It's a feedback loop. The warmer it gets, the faster it is happening.
The input side is going up because of carbon dioxide emissions, but the output is going up because of temperature rises.
All the consequences of global warming will occur more rapidly. That's the scary thing: the amount of time we have got to do something about it is smaller than we thought.
