Assessing Urban Green Roofs for CO2 Removal via Enhanced Rock Weathering in Europe
Authors: Liam A. Bullock, Rasesh Pokharel, Amy Lewis, et al.
Synopsis: This conceptual study evaluates ERW applied to urban green roofs as a carbon dioxide removal strategy. It estimates that, under ideal conditions, European rooftops could remove tens of millions of tonnes of CO₂ by 2060, with global potential reaching hundreds of millions of tonnes annually. Beyond CDR, ERW green roofs may improve energy efficiency and reduce evaporation, but real-world feasibility depends on structural limits, climate conditions, costs, and policy support.

Hemispheric contrast in summer season duration responses to CO2 removal
Authors: Bo-Joung Park, Seung-Ki Min, Soon-Il An, et al.
Synopsis: This study uses climate model simulations with CO₂ ramp-up and ramp-down scenarios to show that summer season length does not fully revert as CO₂ declines, revealing hysteresis in the climate system. Extratropical lands experience longer summers during cooling than warming, with stronger effects in the Southern Hemisphere due to delayed Southern Ocean cooling. In the Northern Hemisphere, both Southern Ocean conditions and Atlantic circulation changes contribute to asymmetric recovery and persistent heat extremes.
Decades of increased emissions from forest-fuelled BECCS
Authors: Timothy D. Searchinger, Liqing Peng, Daniela Russi & Charles Canham
Synopsis: This study evaluates BECCS using wood from existing forests and finds it is unlikely to deliver negative emissions within 150 years. It may generate higher emissions than natural gas without CCS for decades and significantly increase electricity costs. Because most emissions occur upstream and cannot be captured, and wood is carbon-intensive with lower efficiency, the results suggest caution against forest-based BECCS policies.
Scaling Carbon Removal to Gigaton Capacity using Pressurized Direct Air Capture
Authors: Ahmed Elsayed and Thaier Alawadh
Synopsis: This study proposes a high-pressure DAC system that shifts focus from lowering energy per unit CO₂ to increasing air-processing throughput.

By leveraging mature industrial technologies, it aims to enable gigaton-scale CO₂ removal, highlighting turbomachinery and membranes as key areas for future cost reductions.
Potential Impact of Fires on Enhanced Rock Weathering: Learning from the Effects of Fires on Soil Properties and Nutrients
Authors: Karam Abu El Haija, Rafael M Santos
Synopsis: This perspective examines how wildfires may influence enhanced rock weathering (ERW) as a carbon dioxide removal strategy. It finds that fire effects on soil chemistry are highly variable and nonlinear, with temporary ash-driven alkalinity, altered mineral behavior, and increased erosion potentially disrupting weathering processes and carbon accounting. The study highlights fire history as a critical but currently overlooked factor in ERW deployment and monitoring frameworks.
In-depth direct air capture integration to achieve zero-carbon and water data center
Authors: Yuxuan Zhang, Sheng Chen, Mincheng Gao, Xiaojie Lin, Binjian Nie, Yongzhen Wang, Long Jiang
Synopsis: This study proposes integrating DAC with data center operations to reduce both carbon emissions and water use. By using data center waste heat to support DAC desorption, the system improves energy efficiency and enables partial environmental balancing. Case results suggest that zero-carbon operation is achievable under certain electricity emission factors, while additional CO₂ capture is needed to offset water use, supporting the concept of zero-water and zero-carbon data centers.
Microalgae-Based Direct Air Capture Systems for Carbon Dioxide Emission Reductions in Developing Megacities: A Techno-Economic and Policy Analysis
Authors: W.M.S. Dayanath, I.M.S.K. Ilankoon, Shafeeq Ahmed Syed Ali, Meng Nan Chong, Su Chern Foo
Synopsis: This article reviews microalgae-based DAC as an urban carbon mitigation strategy for developing megacities. Compared to trees and conventional DAC, microalgae systems offer higher photosynthetic efficiency and greater CO₂ uptake per biomass while fitting within constrained urban space. The study highlights their potential for carbon neutrality and economic co-benefits, but emphasizes the need for stronger economic analysis, technical validation, and supportive policy frameworks for large-scale deployment.
Investigating the effects of co-applied basalt and biochar on carbon removal efficiency and grain yield in rice paddy
Authors: Xueliu Gong, Jiarong Wu, Jingsong Qin, Jinkai Zhao, et al.
Synopsis: This study evaluates enhanced silicate weathering in rice paddies using basalt and biochar. Basalt alone delivers substantial CO₂ sequestration (~11.3 t CO₂/ha) and yield gains, while adding biochar reduces methane and nitrous oxide emissions and improves soil microbial dynamics. However, combined treatment lowers net mineral-based CDR efficiency compared to basalt alone, highlighting trade-offs between greenhouse gas mitigation, crop yield, and optimal amendment design in flooded agricultural systems.
Rhenium isotopes reveal enhanced rock organic carbon oxidation over the Toarcian Oceanic Anoxic Event
Authors: Madeleine Stow, Alexander J. Dickson, Julie Prytulak, et al.
Synopsis: This study uses rhenium isotope records from Early Jurassic marine sediments to reconstruct changes in organic carbon weathering during the Toarcian Ocean Anoxic Event. Results indicate that 6–7°C global warming intensified oxidation of rock organic carbon, releasing large amounts of CO₂ (estimated 7600–20,490 PgC). This shows that chemical weathering can act as a strong positive climate feedback during extreme warming, rather than a stabilizing one.
Low-cost copper ore oxygen carrier for Bio-CLOU systems: performance assessment and potential for negative-carbon bioenergy (BECCS)
Authors: Tiago Roberto Costa, Amirhossein Filsouf, et al.
Synopsis: This study evaluates a low-cost natural copper ore (CuB) as an oxygen carrier for Bioenergy with Carbon Capture and Storage (BECCS) using Chemical Looping with Oxygen Uncoupling (CLOU). Experiments show high oxygen transport capacity, stable redox cycling, and effective performance under biomass conditions up to 950°C. CuB’s reactivity, durability, and low cost make it a promising material for scalable negative-emission energy systems.
Recognition in climate justice: Lessons from land-based carbon dioxide removal
Authors: Elisa Paiusco
Synopsis: This article re-evaluates the ethics of CDR by extending beyond distributive justice to include recognition justice. Using Fraser’s status-based framework and Caney’s integrationist perspective, it argues that land-based CDR (e.g., BECCS) can overlook Indigenous identities, values, and knowledge systems - especially in regions vulnerable to land grabs. It concludes that recognition is essential for ethically assessing CDR deployment.

Bad Idea #49 “We can stop worrying about the climate” with Zeke Hausfather | WePlanet
“In this episode of Saving the World from Bad Ideas, Mark Lynas speaks with climate scientist Zeke Hausfather about a dangerously complacent idea: we can stop worrying about the climate. As recent years have broken temperature records and warming appears to be accelerating, they explore why that conclusion is badly mistaken.
The conversation unpacks the hidden role of aerosols in masking warming, what recent spikes in temperature do and do not mean, whether net zero really stops further warming, and how seriously we should take tipping points, geoengineering, and carbon removal. The result is a clear-eyed discussion that pushes back against both panic and complacency, and argues for staying focused on the scale and complexity of the climate challenge.”
