Nature-Kantzas et al. (2022): Substantial carbon drawdown potential from enhanced rock weathering in the United Kingdom

Euripides P. Kantzas, Maria Val Martin, Mark R. Lomas, Rafael M. Eufrasio, Phil Renforth, Amy L. Lewis, Lyla L. Taylor, Jean-Francois Mecure, Hector Pollitt, Pim V. Vercoulen, Negar Vakilifard, Philip B. Holden, Neil R. Edwards, Lenny Koh, Nick F. Pidgeon, Steven A. Banwart, David J. Beerling IN: Nature Geoscience (2022). https://doi.org/10.1038/s41561-022-00925-2

Here the authors use dynamic carbon budget modelling to assess the carbon dioxide removal potential and agricultural benefits of implementing enhanced rock weathering strategies across UK arable croplands. They find that enhanced rock weathering could deliver net carbon dioxide removal of 6–30 MtCO2 yr−1 for the United Kingdom by 2050, representing up to 45% of the atmospheric carbon removal required nationally to meet net-zero emissions.

This Is CDR Ep. 30: Verdox’s Electrochemical DAC

by Open Air, hosted by Toby Bryce and Megha Raghavan

„This Is CDR“ welcomed Verdox Co-Founder and Dr. Sahag Voskian and Head of Business Development Jonte Boysen to tell us how the company’s scalable, cost-effective electroswing adsorption (ESA) platform technology, originally developed at MIT, can remove CO2 from the air with 70% energy savings versus conventional approaches (56 min).

C2GLearn: How does the Working Group-II report of the IPCC 6th Assessment address CDR and SRM?

by C2G Carnegie Climate Governance Initiative

This C2GLearn webinar (ca. 1h) aims to provide expert overviews of how the Working Group II contribution to the Sixth Assessment report addresses Carbon Dioxide Removal (CDR) and Solar Radiation Modification (SRM)? Speakers’ presentations were pre-recorded and played to the webinar audience. Afterwards, the speakers participated in the live Q&A session and the audience was able to ask clarifying questions.

Gao et al. (2022): A review of existing and potential blue carbon contributions to climate change mitigation in the Anthropocene

Guang Gao, John Beardall, Peng Jin, Lin Gao, Shuyu Xie, Kunshan Gao IN: Journal of Applied Ecology, https://doi.org/10.1111/1365-2664.14173, accepted

The authors review the alterations to carbon capture and sequestration of marine primary producers (including traditional ‘blue carbon’ plants, microalgae, and macroalgae) in the Anthropocene, and, for the first time, assess and compare the potential of various marine primary producers to carbon neutrality and climate change mitigation via biogeoengineering approaches.

AbdulRafiu et al. (2022): The dynamics of global public research funding on climate change, energy, transport, and industrial decarbonisation

Abbas AbdulRafiu, Benjamin K. Sovacool, Chux Daniels IN: Renewable and Sustainable Energy Reviews, Vol. 162, 2022, 112420, doi.org/10.1016/j.rser.2022.112420.

This paper explores the funding trends, topical themes, and notable gaps in global public research funding across the areas of energy, climate change, transport, and industrial decarbonisation from 1990 to 2020. Climate change adaptation research is the most funded general area, and the specific topics of energy efficiency, climate resilience, and climate information systems, managing climate risks, energy storage, carbon dioxide removal and solar energy are the most funded technologies. It finds that funding for energy and climate research remains concentrated within the European Commission, United Kingdom and United States.

Climate Restoration: The Only Future That Will Sustain the Human Race

by Peter Fiekowsky (author), with Carole Douglis; published 22 April 2022, Rivertown books, ISBN-13: ‎ 978-1953943101, 262 pp.

„As Fiekowsky explains in Climate Restoration, this will require removing a trillion tons of excess CO2 from the atmosphere. The good news is that this task, while enormous and technically challenging, is eminently feasible. Scientists and engineers have developed four major technologies for greenhouse gas removal and storage: Ocean iron fertilization; synthetic limestone manufacture; seaweed permaculture; and methane oxidation. Fiekowsky shows that these technologies are safe and practical-and, even more remarkable, that they require little if any government funding, since they can be financed largely through existing markets. For these reasons, they have enormous promise as vehicles for achieving climate restoration.“

Analysis: How UK newspapers changed their minds about climate change

by Josh Gabbatiss, Sylvia Hayes, Joe Goodman, Tom Prater on Carbon Brief

The past decade has seen a significant shift in the attitudes of UK newspapers towards climate change, according to new analysis undertaken by Carbon Brief. Drawing from a database of more than 1,300 editorials, which are the formal “voice” of a newspaper, this work examines how the language used to describe human-caused climate change, as well as renewables, fracking and nuclear power, has shifted since 2011.

Ahlström et al. (2022): Sustainable Aviation Fuels – Options for Negative Emissions and High Carbon Efficiency

Johan M. Ahlström, Yawer Jafri, Elisabeth Wetterlund, Erik Furusjö; 59 pp. available at SSRN, http://dx.doi.org/10.2139/ssrn.4077522

The authors investigate seven different pathways for producing aviation biofuels coupled with either bio-energy carbon capture and storage (BECCS), or bio-energy carbon capture and utilization (BECCU). Both options allow for increased efficiency regarding utilization of feedstock carbon. The analysis uses process-level carbon- and energy balances, with carbon efficiency, climate impact and LCOP as primary performance indicators.
