CMIP6 models agree on similar carbon cycle feedbacks between enhancing terrestrial and marine carbon sinks

Environmental Research Letters
Carbon dioxide removal (CDR) is a crucial component of climate mitigation required to reach international climate targets. However, gaps exist in our understanding of the responses and feedbacks of the Earth system to the deployment of CDR. In this study,

Regional ocean biogeochemical modeling challenges for predicting the effectiveness of marine carbon dioxide removal

Frontiers in Climate
Effectively scaling diverse marine carbon dioxide removal (mCDR) technologies from pilot-scale demonstrations to industrial-scale deployments requires a quantitative understanding of how much additional carbon a given deployment will sequester compared ...

Carbon Dioxide Removal Rate By Aeration Devices In Marine Fish Tanks [PDF]

Israeli Journal of Aquaculture - Bamidgeh, 2003
A procedure for measuring the transfer coefficient KLa for the removal rate of carbon dioxide by aeration devices in fish tanks was developed in the National Center for Mariculture in Eilat, Israel. The KLa for a paddlewheel and a submerged aerator were calculated, following experi- ments in which the aeration devices were used simultaneously for both ...

Tracking Climate and Environmental Attention: A News‐Based Composite Index

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This study introduces the Climate and Environmental Attention Index, a composite indicator that tracks media attention to climate and environmental issues. Based on the Semantic Brand Score, the proposed index extracts significant signals from unstructured text, going beyond traditional measures of word frequency and sentiment.

Carbon emission assessment of tunnel infrastructures: From construction to operation

Deep Underground Science and Engineering, EarlyView.
This study develops a lifecycle carbon accounting framework for tunnel infrastructures, covering design, construction, operation, maintenance, and dismantling. Applied to a subsea tunnel case, the framework reveals the carbon emission distribution among four typical tunnel types and highlights potential carbon offset methods for low‐carbon tunnel ...

Phase‐Change‐Activated Slippery Organogel Composite for All‐in‐One Anti‐Corrosion, Antifouling, and Self‐Cleaning

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A super‐slippery liquid‐infused composite organogel is engineered by localized interfacial grafting between hydrogel and oleogel networks, endowing the coating with a durable, multifunctional marine‐protective interface. Dynamic antifouling surfaces have emerged as a promising alternative, offering the potential for eco‐friendly and high‐performance ...

On the Efficiency and Durability of Purposefully Sinking Seaweed Biomass as a Marine Carbon Dioxide Removal Strategy

Earth's Future
Large‐scale farming and purposeful sinking of seaweed has been suggested as a marine Carbon Dioxide Removal (mCDR) strategy. Farmed seaweed uptakes dissolved inorganic carbon (DIC) from the mixed layer, resulting in a CO2 deficit that causes an influx of

Novel Zwitterionic Polydopamine Nanofiller‐Reinforced Hybrid Membranes With Superior Antifouling Performance for Wastewater Treatment

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work reports one‐pot synthesized novel zwitterionic polydopamine‐silica (ZSiPDA) nanofillers for fabricating PES hybrid ultrafiltration membranes with enhanced hydrophilicity, permeability, and antifouling performance. The optimized membrane achieved over 91% humic acid removal and showed strong potential for municipal wastewater treatment.

Rational design of Ni‐based catalysts for methane dry reforming: Recent advances and future perspectives

FlexMat, EarlyView.
Addressing the challenges inherent in dry reforming of methane (DRM), this paper focuses on the structural design and performance optimization of Ni‐based catalysts. The modulation strategies for DRM are systematically reviewed across four dimensions: the micromorphology of active metals, metal‐support interactions, electronic modifications by ...
