Summary/Abstract
This study uses “MAGICC7, a reduced complexity climate-carbon cycle model, to quantify how emissions traced to the Carbon Majors, the world’s 122 largest fossil fuel and cement producers, from 1854–2020 contributed to present-day surface air temperature rise, and sea level rise both historically and projected through 2300.”
The study finds that those actors “contributed 37%–58% to present day surface air temperature rise and 24%–37% to the observed global mean sea level rise to date” and “these emissions through 2020 are expected to contribute an additional 0.26–0.55 m of global sea level rise through 2300.”
