🚨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."
🧵
"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
"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
"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
"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
"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."

Stockholm Exergi announced its decision to build one of the world’s largest BECCS facilities, a $1.3B project set to remove ~800,000 tonnes of CO₂ annually and be operational by 2028.
Enhanced rock weathering startup @EionCarbon secured $33M carbon removal offtake deal with Frontier to remove 78,707 tons of CO₂ (2027–2030) by applying olivine on U.S. Midwest and South farmland.
🚨How do political affiliations shape attitudes toward #SolarGeoengineering?🚨
A conjoint experiment with 2,123 US voters finds that partisanship outweighs message framing—meaning who delivers the message matters more than what the message says.

2/ The discourse on SG as a climate solution is evolving, but public perceptions—especially in the polarized US landscape—remain underexplored. This study () examines how different narratives & partisan sources influence attitudes.nature.com/articles/s4416…
3/Researchers tested 3 SG narratives:
-Complementary: SG as an add-on to emissions cuts
-Substitutive: SG as a standalone climate solution
-Moral hazard: SG as a risky distraction

BlueShift company that aims to unlock sustainable, domestic critical mineral supplies while providing affordable ocean carbon removal exited stealth with $2.1M in pre-seed funding.
Seattle-area startup Homeostasis has secured a $600,000 pre-seed investment to develop technology that removes atmospheric CO₂ and converts it into graphite, which has industrial uses.
Scientists at @NorthwesternU have developed a NEW carbon-negative building material using seawater, electricity & CO₂.
How does it work? And how much CO₂ can it store? Read on:🧵1/12
2/ This study expands on earlier research that focuses on storing CO2 in concrete [nature.com/articles/s4324…] & using electricity to treat seawater for cementing marine soils [nature.com/articles/s4324…].
Researchers are now injecting CO2 while applying electricity to seawater in lab.
3/ PROCESS
To generate the carbon-negative material, the researchers started by inserting electrodes into seawater & applying an electric current. The low electrical current splits water molecules into hydrogen gas (a clean fuel with various applications) & hydroxide ions.
