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.”

🚨Which #CDR techs will actually get the world to net zero? New study finds there's no silver bullet.
BECCS leads engineered removals, DACCS complements it & forests provide crucial early removals, with land, biomass, energy & C prices ultimately deciding the winning mix.🧵1/11
2/ Researchers coupled two integrated assessment models, TIAM-FR (energy system) and GLOBIOM-G4M (land-use system), to examine how land, biomass, and energy interact in delivering CDR under both 2°C and 1.5°C climate scenarios.
3/ The study finds that dedicated energy crops become a major biomass source, supplying 54-55 EJ of bioenergy annually while covering around 215 million hectares of land by the net-zero year.
Biomass becomes a cornerstone of future low-carbon energy systems.
🚨Earth has a mysterious triple symmetry that may influence its climate
New research finds that a circle running along the 27° east & 153° west meridians divides the globe into 2 halves with equal reflectivity & this may have implications for #SolarGeoengineering schemes.🧵1/10
2/ This study matters bcz Earth's reflectivity (albedo) controls how much solar energy stays in the climate system.
For decades, researchers knew the NH & SHemispheres reflect similar amounts of sunlight. But nobody had seriously looked for similar patterns across longitude.
3/ Using 25 years of satellite observations, researchers discovered that the 27°E meridian uniquely splits Earth into eastern & western hemispheres with almost identical reflected sunlight. Not 20°E. Not 40°E. Just one remarkably precise divide.

🚨A new @EarthsFutureEiC study tests an Arctic intervention: flooding winter sea ice with seawater to see if it can become thicker, brighter, and more resistant to summer melt.
The answer comes from a real field experiment in the Canadian Arctic.🧵1/11
2/ The experiment was conducted in Cambridge Bay, Nunavut (Canadian Arctic) using a ~1 km² sea-ice field site.
Researchers divided the ice into control plots (no flooding) and treated plots (artificial flooding) to directly compare outcomes under identical conditions.
3/Process:
•Seawater was pumped from ocean
•Spread manually/with equipment over ice surface during winter
•H2O rapidly froze due to sub-zero air temp
•Process repeated in some plots multiple times over winter
Each flooding cycle added new frozen layer on top of existing ice
