C2G Guest Post: Safeguarding biodiversity in carbon dioxide removal approaches

"Thinking about CDR interventions in terms of threats to biodiversity offers a starting point to highlight positive options, while cautioning against pursuing options that clearly contribute to known drivers of biodiversity loss."

Dooley, Kate; et al. (2020): Carbon‐dioxide Removal and Biodiversity: A Threat Identification Framework

Dooley, Kate; Harrould‐Kolieb, Ellycia; Talberg, Anita (2020): Carbon‐dioxide Removal and Biodiversity: A Threat Identification Framework. In Global Policy. DOI: 10.1111/1758-5899.12828.

"We present a framework for assessing the impacts (positive or negative) on biodiversity and ecosystems from a spectrum of CDR interventions, so as to prioritize research to those CDR options that present minimal threats to biodiversity. Application of the framework indicates that while many CDR interventions present threats to biodiversity, certain options, such as regenerative CDR, may have positive impacts."

C2G Guest Post: Safeguarding biodiversity in carbon dioxide removal approaches

"Carbon dioxide removal (CDR) is garnering increasing attention as part of ‘deep decarbonisation’ pathways to achieve 2°C and 1.5°C temperature limits. However, CDR can also present risks to biodiversity, particularly those techniques that depend on large-scale manipulation of ecosystems and earth-system processes."

Baskin, J. (2019): Geoengineering, the Anthropocene and the End of Nature

Baskin, J. (2019): Geoengineering, the Anthropocene and the End of Nature. Cham: Palgrave Macmillan.

"This book takes a critical look at solar geoengineering as an acceptable means for addressing climate change. Baskin explores the assumptions and imaginaries which animate ‘engineering the climate’ and discusses why this climate solution is so controversial. The book explains geoengineering’s past, its revival in the mid-2000s, and its future prospects including its shadow presence in the Paris climate accord."

Gattuso, J.; et al. (2018): Ocean Solutions to Address Climate Change and Its Effects on Marine Ecosystems

Gattuso, J.; Magnan, A.; Bopp, L.; Cheung, W.; Duarte, C.; Hinkel, J. et al. (2018): Ocean Solutions to Address Climate Change and Its Effects on Marine Ecosystems. In: Front. Mar. Sci. 5, S. 3. DOI: 10.3389/fmars.2018.00337.

"A comprehensive and systematic assessment of 13 global- and local-scale, ocean-based measures was performed to help steer the development and implementation of technologies and actions toward a sustainable outcome. We show that (1) all measures have tradeoffs and multiple criteria must be used for a comprehensive assessment of their potential, (2) greatest benefit is derived by combining global and local solutions, some of which could be implemented or scaled-up immediately, (3) some measures are too uncertain to be recommended yet, (4) political consistency must be achieved through effective cross-scale governance mechanisms, (5) scientific effort must focus on effectiveness, co-benefits, disbenefits, and costs of poorly tested as well as new and emerging measures."

Environmental Research Web: Solar geoengineering threatens global biodiversity

"Geoengineering programmes that inject aerosols into the atmosphere to cool the planet may harm wildlife. That's according to a team of scientists from the US, whose new study suggests that suddenly starting or stopping geoengineering programmes may prevent species from successfully tracking changes in climate."

Trisos, Christopher H.; et al. (2018): Potentially dangerous consequences for biodiversity of solar geoengineering implementation and termination

Trisos, Christopher H.; Amatulli, Giuseppe; Gurevitch, Jessica; Robock, Alan; Xia, Lili; Zambri, Brian (2018): Potentially dangerous consequences for biodiversity of solar geoengineering implementation and termination. In Nat Ecol Evol 355. DOI: 10.1038/s41559-017-0431-0.

"Here, we assess the effects of the rapid implementation, continuation and sudden termination of geoengineering on climate velocities—the speeds and directions that species would need to move to track changes in climate. Compared to a moderate climate change scenario (RCP4.5), rapid geoengineering implementation reduces temperature velocities towards zero in terrestrial biodiversity hotspots. [...] Rapid geoengineering termination would significantly increase the threats to biodiversity from climate change."
