Duurzaam: Climate change can not be faced without geo-engineering (Dutch)

"It will be another job to limit global warming to 2 degrees Celsius.New scientific research states that large-scale filtering of CO2 from the sky is inevitable." (Dutch, auto-translation)

FCEA Blog: Increasing Ambition with Blue Carbon: Protecting Coastal Wetland Ecosystems as a Carbon Dioxide Removal Strategy to Meet the Paris Agreement’s Goals

"The basic idea is to protect coastal wetland ecosystems – mangroves, seagrass beds and salt marshes – because the plant biomass and soils sequester and store carbon at rates up to 50 times higher than their terrestrial counterparts. While sequestration and storage can vary greatly across geographies and ecological conditions, it is estimated that global blue carbon systems store at least 45 Mt CO2 per year. It is further estimated that if coastal wetlands were restored to their extent in 1990, annual carbon sequestration would increase to 160Mt CO2 yr-1. Blue carbon ecosystems also provide a suite of co-benefits, including mitigating sea level rise, providing critical fisheries habitat, and nutrient filtration."

Carnegie Endowment For International Peace: Understanding Climate Engineering

"There is no doubt that a rapid rise in the earth’s temperature will impose high costs on not only our environment and health but also our economic and physical security. In recognition, most nations have committed to significant mitigation efforts. But will these collective efforts be enough? Some scientists are trying another approach, exploring new tools that can deliberately alter the global climate system. The problem is, while several tools seem to be gaining traction, knowledge of them is not widespread and there has been too little transparency and international dialogue around their progress, feasibility, risks, and benefits.1 Documenting and tracking the array of tools in development will be crucial for understanding their full impact, debating their implementation, and safeguarding their appropriate use."

Environmental Guru: Why Procedural Justice Matters for Climate Engineering

"It is fairly obvious that substantive justice matters for climate engineering policies. This is true of both solar radiation management and greenhouse gas removal varieties, because either could affect the distribution of burdens and benefits among persons. Because of this, we could evaluate whether some such policy is likely to secure the distribution required by substantive justice (whatever that might be). The result of this evaluation might give us ethical reasons to oppose or support the policy in question."

Euractiv: Dangerous global warming unstoppable without geo-engineering, says study

"The international community has already missed its chance to limit global warming to between 1.5 and 2 degrees Celsius, according to a new study by Switzerland-based researchers. But a solution to the problem could lie in geo-engineering technologies."

Psarras, Peter; et al. (2017): Slicing the pie. How big could carbon dioxide removal be?

Psarras, Peter; Krutka, Holly; Fajardy, Mathilde; Zhang, Zhiqu; Liguori, Simona; Dowell, Niall Mac; Wilcox, Jennifer (2017): Slicing the pie. How big could carbon dioxide removal be? In WIREs Energy Environ 6 (5), e253. DOI: 10.1002/wene.253.

"The primary direct removal methods discussed in this review include land management and mineral carbonation in addition to bioenergy and direct air capture with carbon capture and reliable storage. These methods are discussed in detail, and their potential for CO2 removal is assessed."

Campbell-Arvai, Victoria; et al. (2017): The influence of learning about carbon dioxide removal (CDR) on support for mitigation policies

Campbell-Arvai, Victoria; Hart, P. Sol; Raimi, Kaitlin T.; Wolske, Kimberly S. (2017): The influence of learning about carbon dioxide removal (CDR) on support for mitigation policies. In Climatic Change 143 (3-4), pp. 321–336. DOI: 10.1007/s10584-017-2005-1.

"Using an online survey of US adults (N = 984), we tested these competing hypotheses by exposing participants to information about different forms of CDR. We find that learning about certain CDR strategies indirectly reduces support for mitigation policies by reducing the perceived threat of climate change. This was found to be true for participants who read about CDR in general (without mention of specific strategies), bioenergy with carbon capture and storage, or direct air capture."
