🚨NEW STUDY🚨
"Six models are used in a recent study to analyze the climatic, environmental & socio-economic consequences of #overshooting a C budget consistent with the 1.5°C temp target along the cause-effect chain from emissions & #CarbonRemovals to climate risks & impact."
🧵 Image
"Global climatic indicators such as CO2-concentration and mean temperature closely follow the #CarbonBudget #overshoot with mid-century peaks of 50 ppmv and 0.35°C, respectively."
2/10
Findings of this study highlight that "investigating #overshoot scenarios requires temporally and spatially differentiated analysis of climate, environmental and socioeconomic systems."
3/10
Researchers find "persistent and spatially heterogeneous differences in the distribution of #carbon across various pools, ocean heat content, sea-level rise as well as #economic damages."
4/10 ImageImage
"Moreover, it was find in the study that key impacts, including degradation of marine ecosystem, heat wave exposure & economic damages, are more severe in equatorial areas than in higher latitudes, although absolute #temperature changes are stronger in higher latitudes."
5/10 Image
"The detrimental effects of a 1.5 °C warming and the additional effects due to #overshoots are strongest in non-OECD countries (Organization for Economic Cooperation and Development)."
6/10 Image
"Constraining the overshoot inflates CO2 prices, thus shifting #CarbonRemoval towards early #afforestation while reducing the total cumulative deployment only slightly, while mitigation costs increase sharply in #DevelopingCountries."
7/10 Image
"Thus, scenarios with C budget overshoots can reverse global mean temp increase but imply more persistent & geographically heterogeneous impacts. Overall, the decision about #overshooting implies more severe trade-offs btw #mitigation & impacts in #DevelopingCountries."

🚨Should SRM Be Seen as a Serious Security Issue?

Four experts offer their thoughts on the potential security risks associated with sunlight reflection methods (#SRM), or solar geoengineering, highlighting the geopolitical complexity of the field.

Read here:🧵1/6
Burgess Langshaw Power argues climate change is now a security issue and SRM could be too, but warns against military control to avoid secrecy or an arms race.

2/6 Image
Josh Horton says SRM isn’t a direct threat but could indirectly heighten geopolitical tensions if deployment disputes emerge.

🚨A new study in Communications Sustainability explores whether enhanced rock weathering (#ERW) can scale into a meaningful, equitable climate solution.

The headline: ERW could remove ~1GtCO₂/yr by 2100, but who deploys it, when & how fast will shape its global impact.🧵1/10 Image
2/ Enhanced rock weathering works by spreading crushed silicate rocks on croplands.

These minerals chemically react with CO₂, locking carbon into stable forms while improving soil quality. It’s a rare intervention promising both climate mitigation and agricultural co-benefits.
3/ But technical potential alone doesn’t determine climate outcomes. The central question the paper asks is:

How does ERW adoption diffuse across countries under real-world economic, social, and political conditions?

🚨New study finds #biochar made from bioenergy crops & residues in China could remove up to 1.88 GtCO₂/yr with optimized plant logistics and dedicated biomass.

At ~$10/tCO₂, far cheaper than #BECCS, it offers a scalable, cost-effective carbon removal (#CDR) pathway.

🧵1/13 Image
2/ Biochar, a carbon-rich solid produced by pyrolysis of biomass, locks carbon into soils for decades to centuries while improving soil quality and crop yields.

Its stability makes it a promising negative emissions technology (NET) relied on in climate scenarios.
3/ The authors evaluate a hybrid system called BCBE, biochar production with biomass supply from dedicated bioenergy crops grown on abandoned cropland, plus agricultural and forestry residues.

This aims to reduce competition with food production.

🚨🗞️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.

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.
