“…Solar geoengineering research takes places mainly at universities and institutes where scientists (not engineers) are leading projects [31]. Typically, when solar geoengineering priorities and challenges are defined, natural scientists are the ones who tend to be called on first [32]. This is not to say engineers are completely absent but rather that they are normally brought in by scientists to demonstrate technical feasibility [33,34], costeffectiveness [35,36] or design architecture for field experiments [37].…”

“…Various proposals have been made for cooling the Earth, or part of it, by reducing the amount of sunlight reaching its surface. 276 These Solar Radiation Management (SRM) concepts include ideas such as placing a giant sunshield in space; 277 but discussion tends to concentrate on two ideas that would block sunlight within the atmosphere. Stratospheric Aerosol Injection would release particles of sulphate dust into the atmosphere from balloons or aeroplanes.…”

The environmental crisis is increasing risks to security and peace worldwide, notably in countries that are already fragile. Indicators of insecurity such as the number of conflicts, the number of hungry people and military expenditure are rising; so are indicators of environmental decline, in climate change, biodiversity, pollution and other areas. In combination, the security and environmental crises are creating compound, cascading, emergent, systemic and existential risks. Without profound changes of approach by institutions of authority, risks will inevitably proliferate quickly. Environment of Peace surveys the evolving risk landscape and documents a number of developments that indicate a pathway to solutions––in international law and policy, in peacekeeping operations and among non-governmental organizations. It finds that two principal avenues need to be developed: (a) combining peace-building and environmental restoration, and (b) effectively addressing the underlying environmental issues. It also analyses the potential of existing and emerging pro-environment measures for exacerbating risks to peace and security. The findings demonstrate that only just and peaceful transitions to more sustainable practices can be effective––and show that these transitions also need to be rapid.

“…Scientific research purports to lay out both the dangers of solar radiation management (SRM) and its potential for substantial climate hazard reduction. 179 Changes to the carbon cycle and the response of ocean ecosystems to solar geoengineering remain major uncertainties in the deployment of such technology, 180 with further modelling of diverse climate processes in simulations the only means of substantially testing the consequences of SRM proposals. However, even extensive modelling can only reduce, not eliminate, uncertainties.…”
