Volcanic Rocks Will Do, When Studying Biggest Carbon Emitters

Researchers estimated the carbon emissions from the 91 most actively degassing volcanoes on Earth. For inaccessible volcanoes where close-up gas monitoring is not possible, they used a combination of satellite data and the composition of volcanic rocks to estimate carbon flux.
