Climate engineering
Climate engineering, also referred to as geoengineering or climate intervention, is the deliberate and large-scale intervention in the Earth’s climatic system with the aim of limiting adverse climate change. Climate engineering is an umbrella term for two types of measures: carbon dioxide removal and solar radiation management. Carbon dioxide removal addresses the cause of climate change by removing one of the greenhouse gases (carbon dioxide) from the atmosphere. Solar radiation management attempts to offset effects of greenhouse gases by causing the Earth to absorb less solar radiation.Climate engineering approaches are sometimes viewed as additional potential options for limiting climate change, alongside mitigation and adaptation. There is substantial agreement among scientists that climate engineering cannot substitute climate change mitigation. Some approaches might be used as accompanying measures to sharp cuts in greenhouse gas emissions. Given that all types of measures addressing climate change have economic, political or physical limitations a some climate engineering approaches might eventually be used as part of an ensemble of measures. Research on costs, benefits, and various types of risks of most climate engineering approaches is at an early stage and their understanding needs to improve to judge their adequacy and feasibility.No known large-scale climate engineering projects have taken place to date. Almost all research into solar geoengineering has consisted of computer modelling or laboratory tests, and attempts to move to real-world experimentation have proved controversial for many types of climate engineering. Some practices, such as planting of trees and whitening of surfaces as well as bio-energy with carbon capture and storage projects are underway, their scalability to effectively affect global climate is however debated. Ocean iron fertilization has been given small-scale research trials, sparking substantial controversy.Most experts and major reports advise against relying on geoengineering techniques as a simple solution to climate change, in part due to the large uncertainties over effectiveness and side effects. However, most experts also argue that the risks of such interventions must be seen in the context of risks of dangerous climate change. Interventions at large scale may run a greater risk disrupting natural systems resulting in a dilemma that those approaches that could prove highly (cost-) effective in addressing extreme climate risk, might themselves cause substantial risk. Some have suggested that the concept of geoengineering the climate presents a moral hazard because it could reduce political and public pressure for emissions reduction, which could exacerbate overall climate risks.Groups such as ETC Group and some climate researchers (such as Raymond Pierrehumbert) are in favour of a moratorium on out-of-doors testing and deployment of SRM.
