ABC News: Saviour or scientific hubris? Geoengineering the planet to counter climate change

„By 2010 a large number of „geoengineering“ experiments were under consideration — but now major experimentation appears to have stalled. The reasons why reflect the difficulties in trying to deliberately manipulate a system as complex and fragile as the Earth’s environment. They may also speak to the limits of political will, the public’s fear of human meddling, and the problematic line between innovation and scientific hubris.“

European Academies’ Science Advisory Council: Emissions Trading System: Stop Perverse Climate Impact of Biomass by Radically Reforming CO2 Accounting Rules

„Several European countries who are considered leaders in climate protection owe their apparently good emission reductions to biomass. These might turn out to look quite different in the future, if carbon-accounting under the Emissions Trading System (ETS) were to be based on science and the real effects on climate. As the European Commission works on a revision of its central climate policy tool, the European Academies’ Science Advisory Council suggests a radically new standard.“

Carton, Wim; et al. (2020): Negative emissions and the long history of carbon removal

Carton, Wim; Asiyanbi, Adeniyi; Beck, Silke; Buck, Holly J.; Lund, Jens F. (2020): Negative emissions and the long history of carbon removal. In Wiley Interdisciplinary Reviews-Climate Change. DOI: 10.1002/wcc.671.

„In this article, we survey this “long history” of carbon removal and seek to draw out lessons for ongoing research and the emerging public debate on negative emissions. We argue that research and policy on negative emissions should proceed not just from projections of the future, but also from an acknowledgement of past controversies, successes and failures.“

CarbonBrief: Guest post: Learning from the contentious history of ‘carbon removal’

„This literature – even when it questions the assumptions and feasibility constraints underpinning large-scale CDR – tends to frame the various CDR approaches as novel and untested, and mostly focuses on hypothetical future scenarios. Yet CDR has a longer and, in many ways, more tangible history than this framing suggests – the lessons of which are largely overlooked in much of the current debate.“
