About the project
The main objective of this project is to explore – through climate model simulations – the potential, as well as side effects, of proposed climate engineering techniques. Climate engineering, or geo-engineering, has recently been proposed as a possible future supplement to mitigation, in particular in the event of a climate emergency. In order to meet the main objective, the project will carry out dedicated simulations using the Norwegian Earth System Model, exploring and comparing aspects of three different climate engineering techniques, followed by a careful statistical analysis of the results. An important aspect in clarifying the potential future role of climate engineering is our ability to separate the effect of climate engineering (signal) from natural (and man-made) climate variability (noise). This will be addressed in the project. Also, special attention will be given to the response of biogeochemical interactions, both on land and in the ocean. The purpose of this project is not only to learn more about aspects of climate engineering per se, but also to gain new insight into interactions between forcings, internal variability and response in the climate system. The project is coordinated by University of Oslo, with Uni Research Climate as a partner.
