Stratospheric Aerosol Injection
Examining SAI's potential to reflect a small percentage of incoming sunlight using stratospheric aerosols — with a focus on systems engineering, feasibility, and risk characterization.

CCI does not advocate for SRM deployment. We support emissions reduction, adaptation, and carbon removal as the first and most important responses to climate change.
Our work is focused on responsible scientific research and contingency planning. We study potential climate-risk mitigation options so that society can better understand what may or may not be technically feasible, safe, governable, and appropriate in severe climate-risk scenarios.
CCI is committed to open science, transparency, accountability, independent review, and governance-first research. We believe powerful climate technologies must be evaluated carefully before crisis conditions force rushed decisions.
SRM is not a substitute for emissions reductions, adaptation, or carbon removal. It should only be studied with humility, caution, and strong public-interest governance.
We research technologies to reduce risks from severe climate change. Our focus is on novel, game-changing opportunities employing Sunlight Reflection Methods (SRM). We publish our research contributions and disseminate information for informed decision making and development of governance policies.

Explore Governance WorkWe combine cross-disciplinary research with systems engineering to identify concepts that are both scientifically grounded and operationally viable.
How we workBridging climate science, atmospheric physics, fluid dynamics, and environmental engineering to examine SRM at the intersection of disciplines where insight is most needed.
Applying engineering rigor to evaluate real-world feasibility, technical constraints, and operational limits — the most neglected aspects of SRM research.
All findings are published, peer-reviewed, and openly shared. We characterize uncertainty honestly and avoid advocacy. Evidence guides our work, not outcomes.
All research data, methods, and findings are published openly. No proprietary barriers. Public-interest science requires public access.
No SRM research can be responsible without parallel governance development. We treat policy accountability as inseparable from scientific progress.
Every methodology, assumption, and limitation is documented and disclosed. We characterize uncertainty honestly rather than overstating what we know.
CCI does not advocate for SRM deployment. We produce knowledge that enables informed decision-making — not conclusions that predetermine it.
Emissions reduction, adaptation, and carbon removal are the top priority. SRM research explores contingency options — not substitutes for the critical work already required.
Our work is funded and conducted in the public interest. No commercial applications. No proprietary advantage. Just the knowledge humanity may need.
Tom brings a multidisciplinary record of technical leadership, research, and innovation to his role as founder. He previously founded an R&D company and served as Principal Investigator on National Science Foundation and commercial research programs. His work included patenting and manufacturing aircraft components and authoring more than a dozen peer-reviewed papers. In 2006, he shifted focus to mission assurance for U.S. government launches on SpaceX rockets. He served as a Senior Principal Engineer across multiple technical disciplines and supported various "gray beard" expert technical panels. In 2024, Tom turned his attention to applying aerospace technology to climate challenges.
Qiong holds two Masters degrees (Physics and Mechanical Engineering) and a PhD in Electrical and Computer Engineering from Purdue (1996), focused on machine learning for hyperspectral satellite imagery. She then served 14 years as technical lead and management developing space-based sensors at Northrop Grumman. In 2016 she shifted to finance, becoming a licensed financial advisor and certified financial planner. She is now owner of a rapidly growing financial services company with nine figures under management. Her philanthropic support has enabled the formation of CCI.
Joe is a veteran of California's aerospace industry specializing in environmental testing and hardware integration. He provided long-term mission assurance for NASA weather missions (JPSS and GOES) and numerous USAF and USSF programs, and has been involved in satellite, rocket, and military aircraft testing for Hughes, Raytheon, and The Aerospace Corporation. He earned his MSME from Loyola Marymount University in 1991 and is now applying his career of testing rigor to climate risk mitigation.
CCI has completed Preliminary Feasibility Reviews on its first research programs and is seeking support to expand scientific and engineering capacity.
