From Tokyo Institute of Technology

An international and interdisciplinary team with members from Costa Rica, Iceland, Italy, Japan, the US, the UK, and Turkey, including several from the Earth-Life Science Institute (ELSI) at Tokyo Institute of Technology, and the ELSI Origins Network, have reported new estimates for the amount of carbon cycling on a global scale between Earth’s crust and mantle. The efficiency of this transfer has profound implications for Earth’s deep mantle and shallow crust, and the proportions of carbon being routed through this mechanism were previously poorly understood. The new finding lowers estimates for the efficiency of carbon subduction by 20% and has important implications for understanding Earth’s past and present climate.
