Jackson, R. B.; et al. (2017): Focus on negative emissions

Jackson, R. B.; Canadell, J. G.; Fuss, S.; Milne, J.; Nakicenovic, N.; Tavoni, M. (2017): Focus on negative emissions. In Environ. Res. Lett. 12 (11), p. 110201. DOI: 10.1088/1748-9326/aa94ff.

" One option increasingly invoked in integrated assessment models (IAMs) is negative emissions, defined as the net removal of CO2 from the atmosphere. Two of the most commonly proposed alternatives are biomass energy with carbon capture and sequestration (BECCS) and direct air capture (DAC). However, little is known about the global potential of emerging and future negative emissions technologies, the sustainability and cost of large-scale deployment needed to meet "safe" climate stabilization targets, and the carbon-climate feedbacks of entering a new carbon-negative world. These knowledge-gaps are the focus of the proposed special issue: [...]"

Geden, Oliver; Löschel, Andreas (2017): Define limits for temperature overshoot targets

Geden, Oliver; Löschel, Andreas (2017): Define limits for temperature overshoot targets. In Nature Geosci 6, p. 827. DOI: 10.1038/s41561-017-0026-z.

"Temperature overshoot scenarios that make the 1.5 °C climate target feasible could turn into sources of political flexibility. Climate scientists must provide clear constraints on overshoot magnitude, duration and timing, to ensure accountability."

Bioenergy Insight: Bioenergy combined with CCS will help UK to transition to low-carbon energy economy, expert says

"Bioenergy technologies combined with carbon capture and storage (CCS) can play a significant role in the UK’s future UK energy system, according to Energy Technologies Institute (ETI) strategy manager for bioenergy Hannah Evans. The ETI is a UK-based company formed from global industries and the UK government. It was formed in 2007, but its programme is officially ending at the end of this year."

Ingenioren: Geoengineering can create hurricanes or drip on opposite hemisphere (Danish)

"Using aerosols as a sun shield can have catastrophic consequences in parts of the world unless both hemispheres of the earth are covered. It shows a new study published in Nature, which calls for immediate regulation to be introduced in this area." (Google Translate)

CEC17: Opening Event (Video)

"Due to the limited success of efforts to reduce greenhouse gas emissions, climate engineering (CE) has been increasingly studied in recent years. Often defined as intentional, large-scale interventions in the global climate to counteract some of the effects of climate change, climate engineering techniques continue to be the subject of contentious debate in different in political, scientific and cultural fora. Following the success of the first large international conference on climate engineering in 2014, the IASS and its partners hosted the Climate Engineering Conference 2017: Critical Global Discussions – in Berlin from 9 to 12 October 2017."

Dooley, Kate; Kartha, Sivan (2017): Land-based negative emissions. Risks for climate mitigation and impacts on sustainable development

Dooley, Kate; Kartha, Sivan (2017): Land-based negative emissions. Risks for climate mitigation and impacts on sustainable development. In Int Environ Agreements 354 (13), p. 182. DOI: 10.1007/s10784-017-9382-9.

"We argue that this is two to three times greater than the amount of land-based NETs that can be realistically assumed, given critical social objectives and ecological constraints. Embarking on a pathway that assumes unrealistically large amounts of future NETs could lead society to set near-term targets that are too lenient and thus greatly overshoot the carbon budget, without a way to undo the damage. Pathways consistent with 1.5 °C that rely on smaller amounts of NETs, however, could prove viable. This paper presents a framework for assessing the risks associated with negative emissions in the context of equity and sustainable development."

Lannoy, Charles-Francois de; et al. (2017): Indirect ocean capture of atmospheric CO2. Part I. Prototype of a negative emissions technology

Lannoy, Charles-Francois de; Eisaman, Matthew D.; Jose, Arun; Karnitz, Stephen D.; DeVaul, Richard W.; Hannun, Kathy; Rivest, Jessy L.B. (2017): Indirect ocean capture of atmospheric CO 2. Part I. Prototype of a negative emissions technology. In International Journal of Greenhouse Gas Control. DOI: 10.1016/j.ijggc.2017.10.007.

"We present the design, construction, characterization, and analysis of a prototype process for a novel electrochemical platform of candidate negative emissions technologies (NETs), termed indirect ocean capture. The IOC technologies remove carbon dioxide gas from the atmosphere by leveraging both air-ocean gas exchange and the pH sensitivity of the ocean’s carbonate buffer system. The system characterized in this paper enables two configurations that capture CO2 either as a pure gas or as a solid mineral."
