"A comprehensive #bioenergy accounting model with a multi-dimensional analysis was
developed in a new study based in #China by combining spatial, life-cycle, and multi-path analyses."
Summary in a 🧵 below ⬇️ 1/6
Accordingly, "the #bioenergy production potential and #GHG emission reduction for each distinct type of #biomass feedstock through different conversion pathways were estimated in the study." 2/6
"The sum of all available organic waste (21.55EJ/yr) & energy plants on marginal land (11.77EJ/yr) in China produced 23.30EJ of #bioenergy & reduced 2535.32Mt CO2-eq emissions, accounting for 19.48% & 25.61% of China’s T energy production & C emissions in 2020, respectively." 3/6
Furthermore, in this study, "life-cycle emission reductions were maximized by a mix of #bioenergy end uses based on #biomass properties, with an optimal 78.56% bioenergy allocation from biodiesel, densified solid biofuel, biohydrogen, and #biochar." 4/6

Frontier signed $31.6M offtake with Hafslund Celsio to remove 100,000 tons of CO₂ (2029–2030)—via the first-ever carbon removal retrofit of a waste-to-energy plant at Celsio’s Oslo facility.
🚨 @UKRI_News & @NERCscience is investing £10 million in four NEW research projects, launching this month as part of a 5-year programme—Modelling Environmental Responses to Solar Radiation Management (#SRM)—to assess the risks, limitations & trade-offs of SRM.
DETAILS:🧵1/8
2/ Project 1: Holistic Risk Assessment of SRM
Led by @imperialcollege, @BristolUni, @UniversityLeeds & @UniofExeter
The team will develop a new framework combining Earth system modelling with social & political analysis to better assess risks & trade-offs of SRM—especially #SAI
3/ Project 2:Marine CLOUD Brightening
Led by Uni of Exeter, Leeds, Reading, Manchester & Oxford
MACLOUD will model how spraying sea salt to brighten marine clouds could influence weather patterns, climate & ecosystems—looking closely at how cloud behavior changes at diff scales
🚨🌋 A new UCLA-led study reveals surprising findings about the 2022 Hunga Tonga—Hunga Haʻapai underwater volcanic eruption. Despite fears it would push global temps past 1.5°C, it actually cooled the Southern Hemisphere by 0.1°C!
Here's why:🧵1/8
#SolarGeoengineering #Aerosols
2/ When Hunga Tonga erupted in January 2022, scientists expected the massive release of water vapor to trigger warming, but a key factor shifted: The eruption produced smaller sulfate aerosols that unexpectedly cooled the atmosphere!
3/ Traditionally, sulfate aerosols cool the Earth by reflecting sunlight, while water vapor warms it. The eruption's aerosols were 50% smaller than those from previous eruptions (like Pinatubo, 1991), which made them more efficient at cooling!

Stockholm Exergi announced its decision to build one of the world’s largest BECCS facilities, a $1.3B project set to remove ~800,000 tonnes of CO₂ annually and be operational by 2028.
Enhanced rock weathering startup @EionCarbon secured $33M carbon removal offtake deal with Frontier to remove 78,707 tons of CO₂ (2027–2030) by applying olivine on U.S. Midwest and South farmland.
🚨How do political affiliations shape attitudes toward #SolarGeoengineering?🚨
A conjoint experiment with 2,123 US voters finds that partisanship outweighs message framing—meaning who delivers the message matters more than what the message says.
DETAILS🧵1/9
2/ The discourse on SG as a climate solution is evolving, but public perceptions—especially in the polarized US landscape—remain underexplored. This study () examines how different narratives & partisan sources influence attitudes.nature.com/articles/s4416…
3/Researchers tested 3 SG narratives:
-Complementary: SG as an add-on to emissions cuts
-Substitutive: SG as a standalone climate solution
-Moral hazard: SG as a risky distraction
