Warming of 2°C would release billions of tonnes of soil carbon: Study
A University of Exeter-led study said global warming of 2°C would lead to about 230 billion tonnes of carbon being released from the world's soil. The estimated 230 billion tonnes of carbon released at 2°C warming (above pre-industrial levels) is more than four times China's total emissions. Global soils contain two-three times more carbon than the atmosphere, the study said.
