Solar geoengineering in particular could not be a replacement for reducing emissions mitigation or coping with a changing climate.
Geoengineering refers to a set of emerging technologies that could manipulate the environment and partially offset some of the impacts of climate change. For those looking to stall meaningful climate action, the active development of geoengineering. But because a geoengineering policy avoids the pitfalls of a traditional, regulationbased climate change strategy, the true believer should still be convinced. Climate change is increasingly becoming an important driver of biodiversity loss and. Until recently, it was mostly discussed as a proposed military tool to control the weather for hostile purposes. Despite this, some scientists and governments continue to consider geoengineering a viable plan b to slow climate change.

Governance and technology policy congressional research service summary climate change policies at both the national and international levels have traditionally focused on measures to mitigate greenhouse gas ghg emissions and to adapt to the actual or anticipated impacts of changes in the climate. Climate change will have significant impacts on vegetation and biodiversity. To avert the worst, we may need to turn to geoengineering the deliberate, largescale manipulation of the environment to counteract climate change. Most geoengineering approaches, however, do not address the problem of increasing ocean acidity. Nonstate governance of solar geoengineering research. Humans are responsible, through the release of carbon dioxide co 2. Policymakers have raised questions about geoengineering largescale deliberate interventions in the earths climate system to diminish climate change or its impactsand its role in a broader strategy of mitigating and adapting to climate change. Developing countries are also least able to recover from such shocks and to adapt to a rapidly changing climate fuhr, 2016b. Evaluating climate geoengineering proposals in the context.
