🚨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."

🚨A recent field study conducted over the Great Barrier Reef has provided key insights regarding sea spray aerosols (SSA).
For the first time, it shows that SSA can reach the cloud base height, advancing Marine Cloud Brightening (#MCB) research.
DETAILS🧵1/8
2/ MCB is a proposed climate intervention that aims to reflect more sunlight by enhancing marine clouds.
The concept relies on artificially generated sea spray aerosols (SSA) at the ocean surface and their transport in sufficient quantities to low-level maritime clouds.
3/ A portion of the SSA that reaches cloud height can act as additional cloud condensation nuclei and modify cloud microphysical properties, potentially reducing the amount of solar radiation reaching the sea surface.
🚨A new 3-year study found that by combining crushed rock + compost + biochar could remove 51.7 million tons of CO₂e/year—just by treating 8% of California’s rangelands.

Here’s the details:🧵1/9
2/ Researchers spread finely crushed metabasaltic rocks across test plots in Browns Valley, California, in each of 3yrs.
Along with the crushed rock, some of the applications included compost or a combination of compost & biochar (burned pine & fir left over from local logging).
3/ Other plots were treated with only compost, and a group of control plots received no treatment.
Throughout the year, the team monitored each plot for levels of soil organic and inorganic carbon, pore water dissolved carbon, aboveground biomass, and greenhouse gas emissions.
