Recent study present an analysis of “the gap between the CO2 storage required to meet net zero targets and the slow maturation of regional storage resources.”
Researchers estimate that “European storage rates need to boost 30-100x by 2030 to meet #NetZero by 2050. 🇨🇳 & North America face a similar challenge. The slow global progress of #CarbonStorage undermines the latest IPCC, IEA & EU transition pathways to net zero by 2050.”

Here, scientists of this study investigate “if sufficient #storage can be developed in time. China 🇨🇳 (30%), (15%) and Europe 🇪🇺(10%) dominate global #emissions.”
In this study, “Europe was chosen as a data-rich exemplar.”

“Assuming #NetZero in 2050, researchers back-calculate the #storage required under 3️⃣ scenarios of low, medium, and high #CCS demand.”
5/12
“Even the low demand scenario requires 0.2 Gt of #storage by 2030, increasing to 1.3 Gt by 2050. The moderate & high demand scenarios require 5-8 Gt by 2050. The current #CarbonStorage rate in #Europe is 0.001 Gt/yr.”
6/12
So, “there is a huge gap btw policy demand & #storage supply. Adaptation of existing #hydrocarbon tech has the potential to close this gap, with CCS for the entire EU requiring less than half the historic rate of HC exploration & development in UK North Sea from 1980-2010.”

“Counter to expectation, #storage cannot be delivered by exponential growth but requires an early & sustained investment of 30-50 boreholes per year starting before 2030 to build sufficient capacity,” researchers affirmed.
8/12
“A 5-year lead-time to identify & mature prospects needs policy intervention before 2025. Continued policy deferral will lock Europe into a low CCS pathway that restricts the contribution of #NETs at a potential cost of €100 billion for every gigatonne delayed beyond 2050.”
9/12
According to this research, “North America & China require similar policy intervention to close the gap on #CarbonStorage and #NetZero.”

🚨Where should Direct Air Capture (#DAC) be deployed to scale carbon removal?
New research shows: costs are driven less by the technology itself and more by location, climate, and energy systems, making DAC a fundamentally geo-dependent solution.
Details🧵1/10
2/ DAC needs to scale to 0.5–5 GtCO₂/year by 2050, yet current capacity is ~0.00004 Gt.
Scaling requires massive cost reductions, and smart siting.
3/ The study evaluates two leading approaches:
• Solid sorbent DAC (S-DAC)
• Liquid solvent DAC (L-DAC)
Using global, high-resolution data on weather and renewable energy availability.
New study suggests that during the Emeishan supervolcanic eruptions (~260M yrs ago), enhanced weathering of uplifted rocks removed huge amounts of atm CO₂, cutting levels nearly in half.
How?🧵1/11
2/ Large igneous provinces (LIPs) are among the largest volcanic events in Earth’s history, typically releasing huge volumes of lava over 1-5 million years.
They’re widely thought to drive CO₂ spikes, warming, and environmental crises through massive volcanic degassing.
3/ To test this assumption, researchers reconstructed atmospheric CO₂ levels across the Emeishan volcanic episode using carbon isotopes from chlorophyll-derived biomarkers preserved in marine sediments from the Shangsi section in China.
🚨How much does the shape of particles matter for #SolarGeoengineering?
A new study tests whether non-spherical particles could improve the cooling efficiency of #SAI.
The result: shape can help slightly, but particle size & refractive index dominate the cooling effect.🧵1/11
2/ SAI aims to cool Earth by injecting particles into the lower stratosphere that scatter incoming sunlight back to space, increasing planetary reflectivity (albedo).
The effectiveness of these particles depends on their optical properties, how they scatter and absorb sunlight.
3/ Most previous studies optimized SAI particles assuming they're perfect spheres, focusing on 2 parameters: particle radius & refractive index.
But real particles in the atm are often irregular or elongated, raising an imp Q: could particle shape improve solar reflection?

2️⃣ AMOC tipping warning & role of SRM - Nordic Council report highlights risks of an Atlantic circulation collapse and urges stronger monitoring and expanded research into climate intervention alongside emissions cuts.
🚨🐜Tiny fungus-farming ants have evolved the ability to capture carbon dioxide from air (#CDR) and convert it into a mineral layer on their bodies, forming a natural protective armour, a surprising biological mechanism reported by scientists in a new study.
Details🧵1/11
2/ The discovery comes from studying crowded ant nests where carbon dioxide can build up.
Instead of simply tolerating high CO₂, these ants appear to use the gas as a chemical resource inside their nest environment.
3/ Fungus-farming ants forage for vegetation to feed cultivated fungi that are grown inside their colonies. In turn, the fungi serve as the primary food source for the ants.
The high density of ants and fungi can result in high concentrations of CO2 inside the nests.
