A team of researchers at the University of Oxford, working with a colleague from the International Institute for Applied Systems Analysis, has created radiative transfer models to help estimate global temperature changes in the coming years due to the Tonga eruption last year. In their paper published in the journal Nature Climate Change, the group suggests that the impact will be large enough to push average global temperatures temporarily above the 1.5°C increase limit targeted in the Paris Agreement back in 2015.
