Near Term Climate Risk
and Intervention


A roadmap for the essential research and investments required to assess rapid climate interventions and their potential to reduce the catastrophic risks of near-term climate change.



SilverLining’s report, Near Term Climate Risk and Intervention: A Roadmap for Research, U.S. Research Investment and International Scientific Cooperation describes a roadmap for the essential research and research investments required to better address the catastrophic risks of near-term climate change.

Current risks and escalating threats of climate change highlight the urgency of research to enhance safety for human and natural systems, especially for those most vulnerable. As the report highlights, the magnitude of these threats warrants a concerted effort to improve projections of near-term climate risks and impacts and to assess the potential for rapid climate interventions to reduce them.


Advancing Critical Science

A coordinated U.S. scientific research effort structured around a 5-year roadmap could fill information gaps on near-term climate risks and deliver a robust scientific assessment of the potential for solar and other promising climate interventions to reduce those risks.

Such a research effort should include improved modeling and analyses of climate and impacts, improved observations of the atmosphere and other natural systems, research on specific sunlight reflection approaches, socio-economic studies, and international scientific programs. A $2.6B annual increase in funding for U.S. federal climate science over the next 5 years—$13B in total—can provide the capabilities and resources needed to assess approaches to improving near-term climate safety.

Climate change is causing devastating impacts on communities and ecosystems around the world. With warming projected to rise through the mid-century, conditions will grow increasingly unsafe.

Climate interventions may provide options for protecting the safety of the world’s people and the stability of its natural systems while society transitions to a sustainable future.


Framework for Global Cooperation

Such a research effort would support international cooperation on science and greater equity in decision-making on near-term climate risks and rapid climate interventions. U.S. scientific research plays a central role in supporting international climate and environmental science and governance for the rest of the world. A coordinated U.S. scientific research effort could facilitate expanded international participation in research to support more effective and equitable decision-making, including for those most affected by climate change.

“To bring global temperatures down quickly, the only button we can push - that we know about - is solar climate intervention. There are many uncertainties, which is why scientists should be studying the issue carefully.”
