🚨📝NEW PAPER 📝🚨

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.”

🧵 1/12 ImageImage
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.”
2/12 Image
“These pathways imply a radically in teased demand for carbon capture and storage & #NegativeEmissionTechnologies (#NETs), contributing 500 of 700 megatonnes of #CarbonDioxideRemoval annually by 2050.”
3/12 Image
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.” 
4/12
“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 Image
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.”
7/12 Image
“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 Image
“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 Image
According to this research, “North America & China require similar policy intervention to close the gap on #CarbonStorage and #NetZero.”

🚨NEW STUDY🚨

Scientists investigate “the potential impact of #StratosphericAerosolIntervention (#SAI) on the spatiotemporal behavior of large-scale climate teleconnection patterns using simulations from the CESM1 & CESM2).” 
🧵1/10 Image
“The leading empirical orthogonal function of #SST anomalies indicates that #GHG forcing is accompanied by increases in variance across both the North Atlantic (i.e., AMO) & North Pacific (i.e., PDO) and a decrease over the tropical Pacific (i.e., ENSO),” researchers inferred.
2/ Image
“However, #StratosphericAerosolInjection (#SAI) effectively reverses these global-warming-imposed changes.”

🚨NEW STUDY🚨
“Given the high expectations placed on #DAC for future #decarbonisation, recent study presents an extensive review of DAC tech, exploring a number of techno-economic aspects, including an updated collection of the current & planned DAC projects around the world.”
🧵 ImageImage
“A dedicated analysis focused on the production of synthetic methane, methanol, and diesel from #DAC and electrolytic hydrogen in the European Union (EU) is also performed, where the #carbonfootprint is analysed for different scenarios and energy sources.”
2/10 Image
The results show that “the maximum grid carbon intensity to obtain #NegativeEmissions with #DAC is estimated at 468 gCO 2 e/kWh, which is compliant with most of the EU countries’ current grid mix.”

🚨📝NEW PAPER📝🚨

A new study from Colorado State University's Dept. of Soil & Crop Sciences & the Graduate Degree Program in Ecology found “that #regenerative practices—including integrating crop & livestock systems—were successful as long-term #CarbonStorage solutions.”
🧵 1/7 Image
Researchers conducted a “global systematic meta-analysis of the effects of #regenerative management practices on Soil Organic Carbon (#SOC), Particulate Organic Carbon (#POC) & Mineral-Associated Organic Carbon (#MAOC) in cropland.”

2/
They found that:
1️⃣ “no-till (NT) and cropping system intensification increase #SOC (11.3% and 12.4%, respectively), #MAOC (8.5% and 7.1%, respectively), and #POC (19.7% and 33.3%, respectively) in topsoil (0 to 20 cm), but not in subsoil (>20 cm).”

🚨NEW STUDY🚨

“Keeping tree diversity intact in Canada's many forests over the long term can help increase carbon capture & mitigate climate change,” according to a new University of Alberta study.
#CarbonSequestration
#CarbonCapture
#CarbonStorage
#NatureBasedSolutions
🧵1/8 Image
The study, published in @Nature, “is the first of its kind to show the sustained benefits of tree diversity on a large spatial scale, in terms of #storing #carbon and nitrogen in the soil. It reinforces the importance of biodiversity conservation in forests.”
2/8
The researchers analyzed “Canada's National Forest Inventory database & used statistical modeling to provide new evidence of a link between greater tree diversity & higher soil C & N accumulation in natural forest ecosystems over decadal time scales.”
