🚨2025 Year in Review: Solar Geoengineering Edition🚨
As we enter 2026, we’re excited to share our yearly summary for #SRM: "Solar Geoengineering in 2025: Rays of Hope, Clouds of Doubt."
Here’s what we cover in this comprehensive review:🧵1/11
2/ 𝐖𝐡𝐚𝐭’𝐬 𝐢𝐧𝐜𝐥𝐮𝐝𝐞𝐝 𝐢𝐧 𝐨𝐮𝐫 𝟐𝟎𝟐5 𝐫𝐞𝐯𝐢𝐞𝐰?
1️⃣ Rising Temp & Escalating Climate Impacts
2️⃣SRM Funding Announcements
3️⃣Top SRM Stories
4️⃣Restrictions & Bans on SRM
5️⃣Essential SRM Reads
6️⃣SRM in Media
7️⃣Research Highlights
8️⃣Our Work Across Geoengineering
3/ 2025 was the third-warmest yr on record. @CopernicusEU shows the last 11 yrs were the warmest ever, with the global average temp in yrs 2023-25 exceeding 1.5 °C. Top climate disasters caused $120B+ in losses, intensifying debates over mitigation, CDR & SRM.
🚨Two recent engineering studies examine whether H2-powered aircraft can reliably deliver large payloads to the lower stratosphere for #SAI.
The papers compare a conventional tube-wing aircraft & a canard-wing alternative, analyzing design feasibility & performance limits🧵1/14
2/ Delivering aerosols to these altitudes with large payloads is difficult using existing aircraft.
Both studies explore H2 propulsion b/c it offers high gravimetric energy density & zero CO₂e, potentially enabling long-duration missions without adding direct C emissions
3/ To enable comparison, both designs are evaluated against the same core mission:
• Climb and cruise at 65,000 ft
• Sustain flight for ~3.5 hours
• Deliver a ~50,000 lb aerosol payload
• Operate near aerodynamic and propulsion limits typical of the lower stratosphere
For smallholder agroforestry, traditional methods are labor-intensive, expensive & hard to scale. As a result, farmers are locked out of climate finance.
3/ So, in this study researchers used an approach "DiameterAlgorithm," a non-contact method that estimates tree diameter (DBH) from a single photograph.
Instead of manual tapes or costly sensors, it relies on computer vision and a simple reference tag placed on the tree.
🚨Monthly Solar Geoengineering Updates (Dec Edition)
From NCAR’s possible shutdown & the Guardian’s sun-dimming debate to an African-led #SRM hub, the EU’s first governance conference & new studies, SRM dominated headlines and labs alike.
Top 10 SRM Highlights (Dec 2025)🧵1/8
1️⃣ Trump administration plans to dismantle NCAR, a leading hub for climate & SRM research
2️⃣ Guardian editorial sparks debate, warning of “sun-dimming” under political control. In response, letters argue research shutdown stifles science & misrepresents African perspectives.
2/
3️⃣ DSG launches SRM Governance Horizons, a project to assess institutional readiness and inclusive governance for solar radiation modification debates.
4️⃣ Sandro Vattioni wins China’s 2025 Pineapple Science Award for research on diamond dust as a potential SRM material.
🚨What if old clothes could power cities & remove CO₂?
New study shows that modular bioenergy with carbon capture (#BECCS) using discarded textiles can cut emissions, beat landfilling on env impacts & deliver durable #CDR at costs competitive with today’s CDR markets.
🧵1/10
2/ ~92 Mt of textile waste are generated globally each year. Roughly half is biogenic (e.g., cotton), meaning it already represents stored atmospheric CO₂ captured by plants during growth.
Yet ~66% of US textiles are landfilled, releasing GHGs & pollutants over time.
3/ In this study, researches model a 100 t/day modular waste-to-energy plant using:
• 100% cotton textiles
• 50/50 cotton–PET blends
Each case is assessed with and without CCS and compared to landfilling using full LCA + techno-economic analysis.
