🚨🗞️Monthly #SolarGeoengineering Updates (Jan 2026)🗞️🚨

From U.S. withdrawal from global climate bodies & anti-geoengineering bills, to SAI uncertainty tool, Arctic field trials & funding calls, SRM stayed at the nexus of sci & geopolitics.

Top 10 SRM Highlights (Jan'26)🧵1/11 Image
1️⃣ 𝗨.𝗦. 𝗲𝘅𝗶𝘁𝘀 𝗨𝗡𝗙𝗖𝗖𝗖 & 𝗜𝗣𝗖𝗖 - Experts warn withdrawal could weaken SRM governance, deepen geopolitical mistrust, and accelerate fragmented or unilateral approaches.

2/11 Image
2️⃣ 𝗔𝗻𝘁𝗶-𝗴𝗲𝗼𝗲𝗻𝗴𝗶𝗻𝗲𝗲𝗿𝗶𝗻𝗴 𝗯𝗶𝗹𝗹𝘀 𝗶𝗻 𝘁𝗵𝗲 𝗨.𝗦. - New Arizona and Iowa state proposals target geoengineering, despite limited evidence and no active SRM programs.

🚨Climate pathways to 1.5°C increasingly depend on land-intensive carbon dioxide removal (#CDR) like forestation and BECCS.

But new research shows these climate solutions could place major pressure on #biodiversity if deployed without safeguards.

Details🧵1/11 Image
2/ Using five integrated assessment models, the study examines where large-scale CDR is projected to occur & and how often it overlaps with biodiversity hotspots and climate refugia, the places most critical for species survival. Image
3/ The analysis focuses on a moderate but realistic deployment level of 6 GtCO₂ per year:
• 3 GtCO₂/yr from forestation
• 3 GtCO₂/yr from BECCS
Even at this level, land pressures are already significant.

🚨The Politics of Geoengineering (book) is out, offering 1st comprehensive social science view of #geoengineering.

It examines political, legal, economic & societal dimensions of CDR & SRM, from Africa to the Asia-Pacific, amid urgent governance & ethical debates

Chapters🧵1/15 Image
2/ Chapter 01: Geoengineering has shifted from theory to contested policy, with technology outpacing governance. The analysis highlights political, legal, economic, and justice dimensions and calls for urgent global oversight.

link.springer.com/chapter/10.100…Image
3/ Chapter 2 examines Carbon Dioxide Removal (CDR) as geoengineering, analyzing CO2 extraction, storage, and conversion, with SWOT insights on techniques and implications for sustainable climate action.

🚨Is carbon dioxide removal (#CDR) in the Arctic really feasible?

A new peer-reviewed study systematically assessed proposed Arctic CDR pathways and finds that feasibility is far more limited than often assumed.

DETAILS🧵1/14 Image
2/ As Arctic warms rapidly (4x) & attracts attention for climate interventions, can it host CDR at meaningful scale?

To answer this, authors conducted a comparative assessment of major CDR approaches proposed for Arctic regions, spanning both nature-based & engineered methods. Image
3/ The analysis draws on existing empirical studies, pilot projects, and modeling literature, evaluating each CDR pathway against biophysical constraints, technical readiness, environmental risks, and governance requirements. Image

7️⃣Research Highlights
8️⃣Our Work Across Geoengineering Image
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. Image

🚨Oceans struggle to absorb Earth's carbon dioxide as microplastics invade their waters, a new study finds.

#CarbonSink #CDR #CarbonSequestration

DETAILS🧵1/12 Image
2/ The ocean is Earth’s largest carbon sink, absorbing vast amounts of CO₂ from the atmosphere.

But tiny plastic particles under 5 mm (microplastics) are now everywhere, from deep sea to Arctic ice, disrupting this natural system. Image
3/ When microplastics enter the ocean, they interact with phytoplankton, the microscopic plants that absorb atm CO₂ through photosynthesis.

Even tiny plastic particles can shade, stress, or damage these organisms, reducing their growth and carbon-fixing ability. Image
