An international team of researchers has created a map that highlights parts of the world that hold very high concentrations of carbon. In their paper published in the journal Nature Sustainability, the group describes their map and how it was created, noting that if the carbon in such areas is released, it would likely set off a climatic catastrophe. Peter Thornton with Oak Ridge National Laboratory has published a News & Views piece in the same journal issue, outlining the work done by the team in this new effort.
