🚨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."

🚨 In a NEW study published today, researchers presented an analysis of the atmospheric sulfur budget using nine state-of-the-art global circulation models with interactive aerosol modules & sulfur chemistry.
In particular, "researchers showcase the burdens of the main sulfur species represented in these models (OCS, sulfate aerosols, and SO2), as well as their latitudinal and vertical distribution and seasonal variability. Emission and deposition fluxes were also discussed."
2/12
FINDINGS:
"Sulfate aerosol, carbonyl sulfide & SO2 behave very differently in the atm, providing insight into the modeled processes. OCS is almost chemically inert in troposphere & is primarily influenced by transport mechanisms but undergoes photolysis in stratosphere."

🧵0/17
@SthlmExergi signed a contract with @Microsoft covering 3.33M tonnes of permanent CDRs over 10 years from BECCS plant at Värtan, Stockholm. "The agreement represents the world's largest permanent removals deal to date."
The Midwest Nuclear DAC Hub (MINDAC) – one of the 19 #DirectAirCapture projects announced for award negotiations by @ENERGY, received the $4 million investment by the DOE.
🚨NEW study explored a system that combines enhanced olivine weathering (EOW) with increased C fixation by diatoms.
EOW can boost ocean's ability to sequester DIC while stimulating diatom growth, which in turn would fix more C & reinforce biological C pump processes. #CDR
🧵1/8
In this study, researchers investigated the short-term synergistic CO2 removal effects of an olivine–diatom coculture system & found that:

1️⃣ "Over a 6-day incubation period, the olivine dissolution was 92%–144% higher in the olivine–diatom groups compared with the olivine-only groups."
🚨🚜 @Veolia, the UK’s leading resource management firm, has partnered with UK biotechnology startup, @fabricnano, to apply enzymes to rocks to trial faster, permanent #CarbonRemoval directly from the atmosphere.
#EnhancedRockWeathering
“With this world-first trial pairing biology with geology to accelerate rock weathering for carbon sequestration, @Veolia aims to reduce the energy consumption, emissions and timescales for carbon removal by utilizing enzymes to accelerate the natural weathering process.”
2/9
“@fabricnano’s patented technology immobilizes the Carbonic Anhydrase enzyme directly onto large particle basalt, accelerating carbon sequestration timelines from decades to just a couple of years.”
