Rosa, Lorenzo; et al. (2020): Hydrological limits to carbon capture and storage

Rosa, Lorenzo; Reimer, Jeffrey A.; Went, Marjorie S.; D’Odorico, Paolo (2020): Hydrological limits to carbon capture and storage. In Nat Sustain 3 (8), pp. 658–666. DOI: 10.1038/s41893-020-0532-7.

"Here we simulate the impacts on water resources that would result from retrofitting global CFPPs with four different CCS technologies. We find that 43% of the global CFPP capacity experiences water scarcity for at least one month per year and 32% experiences scarcity for five or more months per year."

Varney, Rebecca M.; et al. (2020): A spatial emergent constraint on the sensitivity of soil carbon turnover to global warming

Varney, Rebecca M.; Chadburn, Sarah E.; Friedlingstein, Pierre; Burke, Eleanor J.; Koven, Charles D.; Hugelius, Gustaf; Cox, Peter M. (2020): A spatial emergent constraint on the sensitivity of soil carbon turnover to global warming. In Nat Comms 11 (1), p. 5544. DOI: 10.1038/s41467-020-19208-8.

"Here, we present a constraint on ΔCs,τ, which makes use of current heterotrophic respiration and the spatial variability of τs inferred from observations. This spatial emergent constraint allows us to halve the uncertainty in ΔCs,τ at 2 °C to −232 ± 52 PgC."

Rosa, Lorenzo; et al. (2020): The water footprint of carbon capture and storage technologies

Rosa, Lorenzo; Sanchez, Daniel L.; Realmonte, Giulia; Baldocchi, Dennis; D'Odorico, Paolo (2020): The water footprint of carbon capture and storage technologies. In Renewable and Sustainable Energy Reviews, p. 110511. DOI: 10.1016/j.rser.2020.110511.

"This study presents the water footprints (m3 water per tonne CO2 captured) of four prominent CCS technologies: Post-combustion CCS, Pre-combustion CCS, Direct Air CCS, and Bioenergy with CCS. Depending on technology, the water footprint of CCS ranges from 0.74 to 575 m3 H2O/tonne CO2."

Jeltsch-Thömmes, Aurich; et al. (2020): Hysteresis of the Earth system under positive and negative CO 2 emissions

Jeltsch-Thömmes, Aurich; Stocker, Thomas F.; Joos, Fortunat (2020): Hysteresis of the Earth system under positive and negative CO 2 emissions. In Environ. Res. Lett. DOI: 10.1088/1748-9326/abc4af.

"Carbon dioxide removal (CDR) from the atmosphere is part of all emission scenarios of the IPCC that limit global warming to below 1.5circleC. Here, we investigate hysteresis characteristics in 4×pre-industrial atmospheric CO2 concentration scenarios with exponentially increasing and decreasing CO2 using the Bern3D-LPX Earth system model of intermediate complexity."

Low, Sean; Boettcher, Miranda (2020): Delaying decarbonization: Climate governmentalities and sociotechnical strategies from Copenhagen to Paris

Low, Sean; Boettcher, Miranda (2020): Delaying decarbonization: Climate governmentalities and sociotechnical strategies from Copenhagen to Paris. In Earth System Governance 5, p. 100073. DOI: 10.1016/j.esg.2020.100073.

"An era (2005–2015) centered around the Copenhagen Accord saw the rise of several immature sociotechnical strategies currently at play: carbon capture and storage, REDD+, next-generation biofuels, shale gas, short-lived climate pollutants, carbon dioxide removal, and solar radiation management. Through a framework grounded in governmentality studies, we point out common trends in how this seemingly disparate range of strategies is emerging, evolving, and taking effect."

Wang, Jing; et al. (2020): Large Chinese land carbon sink estimated from atmospheric carbon dioxide data

Wang, Jing; Feng, Liang; Palmer, Paul I.; Liu, Yi; Fang, Shuangxi; Bösch, Hartmut et al. (2020): Large Chinese land carbon sink estimated from atmospheric carbon dioxide data. In Nature 586 (7831), pp. 720–723. DOI: 10.1038/s41586-020-2849-9.

"Here we present recently available data on the atmospheric mole fraction of CO2, measured from six sites across China during 2009 to 2016. Using these data, we estimate a mean Chinese land biosphere sink of −1.11 ± 0.38 petagrams of carbon per year during 2010 to 2016, equivalent to about 45 per cent of our estimate of annual Chinese anthropogenic emissions over that period."

Johansson, Daniel J.A.; et al. (2020): The role of negative carbon emissions in reaching the Paris climate targets: The impact of target formulation in integrated assessment models

Johansson, Daniel J.A.; Azar, Christian; Lehtveer, Mariliis; Peters, Glen P. (2020): The role of negative carbon emissions in reaching the Paris climate targets: The impact of target formulation in integrated assessment models. In Environ. Res. Lett. DOI: 10.1088/1748-9326/abc3f0.

"Across two Integrated Assessment Models (IAMs), we found that the amount of net-negative emissions – when global net emissions fall below zero – depends to a large extent on how the target is represented, i.e. implemented in the model."

Nelson, John P.; et al. (2020): Assessing solar geoengineering research funders: Insights from two US public deliberations

Nelson, John P.; Kaplan, Leah; Tomblin, David (2020): Assessing solar geoengineering research funders: Insights from two US public deliberations. In The Anthropocene Review, 205301962096484. DOI: 10.1177/2053019620964845.

"For both normative and pragmatic reasons, actors interested in SRM research and implementation would do well to attend to public preferences and concerns regarding SRM work. But despite growing literature treating public perspectives on SRM governance, little is known about public perceptions or preferences regarding potential SRM research funders. Specific research funders could significantly affect both the varieties, scales, and aims of research performed and public responses to SRM research. Drawing from two deliberative public forums on SRM research involving 171 participants in total, this paper begins to fill this gap in the literature."

Converse, Benjamin A.; et al. (2020): If humans design the planet: A call for psychological scientists to engage with climate engineering

Converse, Benjamin A.; Hancock, Patrick I.; Klotz, Leidy E.; Clarens, Andres F.; Adams, Gabrielle S. (2020): If humans design the planet: A call for psychological scientists to engage with climate engineering. In The American psychologist. DOI: 10.1037/amp0000656.

"The field of psychological science should prepare to help society responsibly consider climate engineering alongside more conventional climate-change responses. This article lays out some initial questions and issues a call to action. It aims to provide common ground for a conversation between climatologists, policymakers, psychological scientists, and members of the public on the important behavioral touchpoints of climate engineering."

Buck, Holly J.; et al. (2020): Adaptation and Carbon Removal

Buck, Holly J., Jay Furhman, David R. Morrow, Daniel L. Sanchez, and Frances M. Wang (2020): Adaptation and Carbon Removal. One Earth 3 (4): 425–35. https://doi.org/10.1016/j.oneear.2020.09.008.

‌"We propose three simple principles for integrating carbon removal and adaptation: identify opportunities for adaptive carbon removal in planning, prioritize adaptive value of projects, and give credit for carbon removed."
