Werner, Constanze; et al. (2018): Biogeochemical potential of biomass pyrolysis systems for limiting global warming to 1.5 °C

Werner, Constanze; Schmidt, H-P; Gerten, Dieter; Lucht, Wolfgang; Kammann, C. (2018): Biogeochemical potential of biomass pyrolysis systems for limiting global warming to 1.5 °C. In Environ. Res. Lett. 13 (4), p. 44036. DOI: 10.1088/1748-9326/aabb0e.

"Negative emission (NE) technologies are recognized to play an increasingly relevant role in strategies limiting mean global warming to 1.5 °C as specified in the Paris Agreement. The potentially significant contribution of pyrogenic carbon capture and storage (PyCCS) is, however, highly underrepresented in the discussion. In this study, we conduct the first quantitative assessment of the global potential of PyCCS as a NE technology based on biomass plantations. Using a process-based biosphere model, we calculate the land use change required to reach specific climate mitigation goals while observing biodiversity protection guardrails. We consider NE targets of 100–300 GtC following socioeconomic pathways consistent with a mean global warming of 1.5 °C as well as the option of additional carbon balancing required in case of failure or delay of decarbonization measures."

Ott, Konrad; Pohlers, Julia (2018): Citizen's jury „Climate Engineering – a oppurtunity against climate change?“

Ott, Konrad; Pohlers, Julia (2018): Bürgergutachten zum Bürgerforum „Climate Engineering – eine Möglichkeit gegen den Klimawandel?“. Schwerin.

"The DFG project TOMACE organized a citizen’s jury to discuss issues of climate engineering. From January until March 2018 a citizen’s jury took place in Schwerin. The organizers invited twenty-five citizens of Germany to discuss during the course of three weekends different issues concerning the climate engineering technologies Stratospheric Aerosol Injection (SAI) and Bioenergy with Carbon Capture and Storage (BECCS). Within a citizen’s jury critical reflection and discussion as well as enabling people to argue for their own point of view is intended.

Turner, P. A.; et al. (2018): The global overlap of bioenergy and carbon sequestration potential

Turner, P. A.; Mach, K. J.; Lobell, D. B.; Benson, S. M.; Baik, E.; Sanchez, D. L.; Field, C. B. (2018): The global overlap of bioenergy and carbon sequestration potential. In Climatic Change 148 (1-2), pp. 1–10. DOI: 10.1007/s10584-018-2189-z.

"Here, we examine the BECCS opportunity that exists in regions overlapping storage basins. Under current conditions, the equivalent of 22.9 GtCO2 y−1 of net primary production (NPP), a measure of biomass growth, overlies highly prospective CO2 storage basins, representing a sustainably harvestable total of approximately 7.6 GtCO2 y−1."

The IVY Podcast: Geoengineering the Climate with Harvard Professor David Keith

"David Keith has some big ideas for the planet. A Professor of Applied Physics at Harvard, David is leading a team of researchers focused on the science and public policy of solar geoengineering, a field that yields innovative ways to manipulate our environment. David and his colleagues believe that solar geoengineering can go a long way toward mitigating the effects of climate change. In this episode of The IVY Podcast, David offers his insights on the technologies, risks, experiments, and governance associated with this field, and what is needed to save the earth."

LSE: What is geoengineering and how could it help tackle climate change?

"Geoengineering, also known as climate engineering, describes a range of ways to intervene on a large scale in the Earth’s natural systems – the oceans, soils and atmosphere – to directly combat climate change. They mostly fall into two categories: those designed to remove carbon dioxide (CO2) from the air and those that try to limit the amount of sunlight that reaches the Earth’s surface."

C2G2: How a game prompted ‘the big talk’ about geoengineering governance

"Big yellow dice, hands miming umbrellas, and a noisy electric bread cutter – these are the ingredients for dialogue about climate geo-engineering governance, right? With the new game Decisions for the Decade, by Pablo Suarez of the Red Cross/Red Crescent, they definitely are."

Ecologist: Can we remove a trillion tons of carbon from the atmosphere?

"The oceans cover 72 percent of the planet - but are all but ignored in discussions about reducing levels of atmospheric carbon to preindustrial levels. In this interview with NICK BREEZE, ocean ecologist Russ George explains how ocean restoration will lower greenhouse gases and bring back fish stocks to levels not seen for generations"
