4. Exploring the challenges of controlling the climate with geoengineering


If geoengineering were ever used, it would not simply be a case of 'turning it on' and leaving it to work. The amount and location of any geoengineering would have to be decided upon continually, and would depend on how the climate was changing in response to it, how much mitigation and adaptation was being undertaken, and what the target climate was agreed to be.

Previous computer simulations of geoengineering tend to ignore this crucial and complex decision-making process and instead typically use a fixed amount of geoengineering applied for a predetermined length of time. IAGP instead used computer models to investigate this process. As part of this research, an 'interactive' computer simulator was developed with solar geoengineering being used to try to control the extent of Arctic sea ice:

This research - led by the Universities of Lancaster, Leeds and Bristol - has produced many insights into what the challenges associated with decision-making for geoengineering could be in the real-world. These insights are presented in Briefing Note 3
