Study finds limited sign of soil adaptation to climate warming

While scientists and policy experts debate the impacts of global warming, Earth’s soil is releasing roughly nine times more carbon dioxide to the atmosphere than all human activities combined. This huge carbon flux from soil — due to the natural respiration of soil microbes and plant roots — raises one of the central questions in climate change science. As the global climate warms, will soil respiration rates increase, adding even more carbon dioxide to the atmosphere and accelerating climate change?
