C2G: Blog post: Carbon Removal: The dangers of mitigation deterrence

"Everyone seems to be talking about trees these days – and in particular, the prospects to remove carbon from the atmosphere by planting more of them."

Carbon Brief: Guest post: The irreversible emissions of a permafrost ‘tipping point’

"Abrupt permafrost thaw is one of the most frequently discussed “tipping points” that could be crossed in a warming world. However, research suggests that, while this thawing is already underway, it can be slowed with climate change mitigation."

Gambhir, Ajay, and Massimo Tavoni (2019): Direct Air Carbon Capture and Sequestration: How It Works and How It Could Contribute to Climate-Change Mitigation

Gambhir, Ajay, and Massimo Tavoni (2019): Direct Air Carbon Capture and Sequestration: How It Works and How It Could Contribute to Climate-Change Mitigation. One Earth 1 (4): 405–9. https://doi.org/10.1016/j.oneear.2019.11.006.

‌"Here, we explain how DACCS works, focusing on two major processes that have been developed into large-scale pilot plants. We discuss cost estimates and operational energy requirements, as well as ecological and ethical considerations. We highlight the role of DACCS in the low-carbon transition by discussing its benefits, while also noting potential trade-offs and uncertainties that deserve further investigation."

Fabre, Adrien; Wagner, Gernot (2019): Risky Geoengineering Option Can Make An Ambitious Climate Mitigation Agreement More Likely

Fabre, Adrien; Wagner, Gernot (2019): Risky Geoengineering Option Can Make An Ambitious Climate Mitigation Agreement More Likely, NYU Wagner Research Paper Forthcoming, 12/9/2019.

"Some countries prefer high to low mitigation (H > L). Some prefer low to high (L > H). That fundamental disagreement is at the heart of the seeming intractability of negotiating a climate mitigation agreement. Enter geoengineering (G). Its risky and imperfect nature makes it arguably inferior to any country’s preferred mitigation outcome. However, absent a global high-mitigation agreement, countries facing disastrous climate damages might indeed wish to undertake it, effectively ranking H > G > L."

Roe, Stephanie; et al.: Contribution of the land sector to a 1.5 °C world

Roe, Stephanie; Streck, Charlotte; Obersteiner, Michael; Frank, Stefan; Griscom, Bronson; Drouet, Laurent et al.: Contribution of the land sector to a 1.5 °C world. In Nat. Clim. Chang., pp. 1–12. DOI: 10.1038/s41558-019-0591-9.

"The Paris Agreement introduced an ambitious goal of limiting warming to 1.5 °C above pre-industrial levels. Here we combine a review of modelled pathways and literature on mitigation strategies, and develop a land-sector roadmap of priority measures and regions that can help to achieve the 1.5 °C temperature goal. "

Hilaire, Jérôme; et al. (2019): Negative emissions and international climate goals—learning from and about mitigation scenarios

Hilaire, Jérôme; Minx, Jan C.; Callaghan, Max W.; Edmonds, Jae; Luderer, Gunnar; Nemet, Gregory F. et al. (2019): Negative emissions and international climate goals—learning from and about mitigation scenarios. In Climatic Change. DOI: 10.1007/s10584-019-02516-4.

"Most recent evidence stresses the importance of future socio-economic conditions in determining the flexibility of NET deployment and suggests opportunities for hedging technology risks by adopting portfolios of NETs. Importantly, our thematic review highlights that there is a much richer set of findings on NETs than commonly reflected upon both in scientific assessments and available reviews. "

DeLisi, C. (2019): The role of synthetic biology in climate change mitigation

DeLisi, Charles (2019): The role of synthetic biology in climate change mitigation. In: Biol Direct 14 (1), S. 1–5. DOI: 10.1186/s13062-019-0247-8.

"There is growing agreement that the aim of United Nations Framework Convention on Climate Change, which is to avoid dangerous anthropogenic interference with the climate system, is not likely to be met without inclusion of methods to physically remove atmospheric carbon. A number of approaches have been suggested, but the community appears to be silent on the potential of one of the most revolutionary technologies of the current century, systems and synthetic biology (SSB)."

Asayama, S.; et al. (2019): Engineering climate debt: temperature overshoot and peak-shaving as risky subprime mortgage lending

Asayama, S.; Hulme, M. (2019): Engineering climate debt: temperature overshoot and peak-shaving as risky subprime mortgage lending. In: Climate Policy 33 (3), p. 1–10. DOI: 10.1080/14693062.2019.1623165.

"Whilst some view optimistically the strategic interdependence between SRM and CDR, we argue that this strategy comes with a risk of escalating ‘climate debt’. We explain our position using the logic of debt and the analogy of subprime mortgage lending. In overshoot and peak-shaving scenarios, the role of CDR and SRM is to compensate for delayed mitigation, placing the world in a double debt: ‘emissions debt’ and ‘temperature debt’."
