Geoengineering is a large-scale deliberate intervention of offsetting the global temperature rise from greenhouse gases. Carbon Dioxide Removal (CDR) is an important form of geoengineering. In this brief review, we introduce the principle science backgrounds behind CDR, the potential efficacy, feedbacks, and side effects of specific CDR methods, as well as the status of CDR in the Integrated Assessment Model (IAM) scenario studies. Recently the Carbon Dioxide Removal Model Intercomparison Project (CDRMIP) was initiated as part of the CMIP6. As a common framework to assess the potential effects and risks of using CDR to address climate change, CDRMIP provides an important opportunity to better understand how the Earth system responds to human climate perturbations.

Key words: CMIP6, Geoengineering, Carbon Dioxide Removal Model Intercomparison Project (CDRMIP), Earth system model (ESM)
