Quote:The purpose was to measure how carbon dioxide may escape from the earth as the atmosphere warms. What they found, published yesterday in the journal Science, may mean the accelerating catastrophe of global warming has been fueled in part by warm dirt. As the Earth heats up, microbes in the soil accelerate the breakdown of organic materials and move on to others that may have once been ignored, each time releasing carbon dioxide into the atmosphere. Extrapolating from their forest study, the researchers estimate that over this century the warming induced from global soil loss, at the rate they monitored, will be “equivalent to the past two decades of carbon emissions from fossil fuel burning and is comparable in magnitude to the cumulative carbon losses to the atmosphere due to human-driven land use change during the past two centuries.”There’s a Climate Bomb Under Your Feet - Bloomberg
