Climate is changing, and the evidence for this fact increases every day. Therefore, research is addressing the question of how the impact of climate change could be alleviated by influencing the climate of the Earth through geoengineering. Research on such issues has increased tremendously since the seminal paper on this topic by Paul Crutzen in 2006. An entire project, the Geoengineering Model Intercomparison Project (GeoMIP), was started in 2010 aimed at understanding the physical processes and projected impacts of solar geoengineering. The paper by Visioni et al. discusses the successes and missed opportunities of the GeoMIP project and gives recommendations regarding both future model experiments and more general activities. The paper will be without doubt a focus and a nucleation point of future discussions on the aspect of geoengineering.
Short summary
Geoengineering indicates methods aiming to reduce the temperature of the planet by means of reflecting back a part of the incoming radiation before it reaches the surface or allowing more of the planetary radiation to escape into space. It aims to produce modelling experiments that are easy to reproduce and compare with different climate models, in order to understand the potential impacts of these techniques. Here we assess its past successes and failures and talk about its future.
