Brienen, R. J. W.; et al. (2020): Forest carbon sink neutralized by pervasive growth-lifespan trade-offs

Brienen, R. J. W.; Caldwell, L.; Duchesne, L.; Voelker, S.; Barichivich, J.; Baliva, M. et al. (2020): Forest carbon sink neutralized by pervasive growth-lifespan trade-offs. In Nat Comms 11 (1), p. 4241. DOI: 10.1038/s41467-020-17966-z.

"Here we show that growth-lifespan trade-offs are indeed near universal, occurring across almost all species and climates. This trade-off is directly linked to faster growth reducing tree lifespan, and not due to covariance with climate or environment. Thus, current tree growth stimulation will, inevitably, result in a lagged increase in canopy tree mortality, as is indeed widely observed, and eventually neutralise carbon gains due to growth stimulation."

Buck, Holly; et al. (2020): Pandemic politics—lessons for solar geoengineering

Buck, Holly; Geden, Oliver; Sugiyama, Masahiro; Corry, Olaf (2020): Pandemic politics—lessons for solar geoengineering. In Commun Earth Environ 1 (1), pp. 1–4. DOI: 10.1038/s43247-020-00018-1.

"Responses to the COVID-19 emergency have exposed break-points at the interface of science, media, and policy. We summarize five lessons that should be heeded if climate change ever enters a state of emergency perceived to warrant stratospheric aerosol injection."

Morton, Evvan V. (2020): Reframing the Climate Change Problem: Evaluating the Political, Technological, and Ethical Management of Carbon Dioxide Emissions in the United States

Morton, Evvan V. (2020): Reframing the Climate Change Problem: Evaluating the Political, Technological, and Ethical Management of Carbon Dioxide Emissions in the United States. Doctoral Dissertation. Arizona State University. Available online at https://repository.asu.edu/items/57290.

"Although research also confirms that negative emission technologies (NETs) are necessary to stay within 1.5-2°C of global warming, this dissertation proposes that the climate change problem has been ineffectively communicated to suggest that CO2 emissions reduction is the only solution to climate change."

Brack, Duncan; King, Richard (2020): Managing Land‐based CDR: BECCS, Forests and Carbon Sequestration

Brack, Duncan; King, Richard (2020): Managing Land‐based CDR: BECCS, Forests and Carbon Sequestration. In Global Policy. DOI: 10.1111/1758-5899.12827.

"To date there has been little focus on the optimum strategies for integrating land‐based CDR approaches – under which circumstances forest areas are best left undisturbed, managed for conservation, and/or managed for harvested wood products, and how these options affect the availability of residual feedstocks for BECCS. This paper reviews this debate and suggests appropriate policy measures."

Rickels, Wilfried; et al. (2020): The Future of (Negative) Emissions Trading in the European Union

Rickels, Wilfried; Proelss, Alexander; Geden, Oliver; Burhenne, Julian; Fridahl, Mathias (2020): The Future of (Negative) Emissions Trading in the European Union. In Kiel Working Paper (2164).

"This conceptual paper explores various design options for integrating negative emissions technologies (NETs) into the EU ETS. We discuss their potential implications for emissions trading at large and address the specificity of bioenergy with carbon capture and storage (BECCS); repealing the provision that installations exclusively using biomass are not covered by the ETS Directive, BE(CCS) installations could in principle fall within the scope of the ETS Directive."

Digdaya, Ibadillah A.; et al. (2020): A direct coupled electrochemical system for capture and conversion of CO2 from oceanwater

Digdaya, Ibadillah A.; Sullivan, Ian; Lin, Meng; Han, Lihao; Cheng, Wen-Hui; Atwater, Harry A.; Xiang, Chengxiang (2020): A direct coupled electrochemical system for capture and conversion of CO2 from oceanwater. In Nat Comms 11 (1), p. 4412. DOI: 10.1038/s41467-020-18232-y.

"Capture and conversion of CO2 from oceanwater can lead to net-negative emissions and can provide carbon source for synthetic fuels and chemical feedstocks at the gigaton per year scale. Here, we report a direct coupled, proof-of-concept electrochemical system that uses a bipolar membrane electrodialysis (BPMED) cell and a vapor-fed CO2 reduction (CO2R) cell to capture and convert CO2 from oceanwater."
