There is a deeper set of conceptual arguments for splitting CDR and SRM that is entirely absent from Duncan McLaren’s argument.
The advantages and disadvantages of solar geoengineering ought to be compared to each other using a cost-benefit analysis. While there has been much discussion about the trade-offs inherent in solar geoengineering, there has been surprisingly little quantitative, formal modeling of these trade-offs.
Is staying below a 2C rise in temperature is a realistic or fantastic target? There’s been talk about this lately, in Nature and on this forum. Beneath this question lies another question: Is there hope?
The ‘Lomborg gambit’ and why the allure of solar geoengineering must be resisted by the Paris negotiators – Prof John Shepherd CBE FRS and Andy Parker
Nothing we know about solar geoengineering should distract you from the task of agreeing deep and binding cuts in CO2 emissions, and effective support for adaptation to climate change. Ignore the siren calls of anyone who attempts another ‘Lomborg gambit’ by dangling solar geoengineering as an alternative to emissions cuts, and get on and agree the climate deal that we – and the planet – so desperately need.
Climate scientists have begun to calculate how we are doing on the 2C goal, and the math is a little frightening. Not only do we have little wiggle room in terms of how much carbon we can emit to have any certainty of staying under this limit, but it will be global actions in the next two decades that determine our fate.
The book’s strength is that it largely achieves these two potentially contradictory tasks. Morton delivers a utopian scenario for climate engineering while still giving enough attention to its possible pitfalls and missteps to reveal just how difficult such a path would be to craft in reality. Time and again he emphasizes the need for care, compassion and justice in in both the purposes and design of a climate geoengineering intervention.
In a brief phone chat recorded by the Forum for Climate Engineering Assessment as part of a new series, Dr. Daniel…
A talk by Holly J Buck – Why Climate Engineering and Sustainable Agriculture Need to Be Part of the Same Conversation
Holly J Buck, FCEA Faculty Fellow and PhD candidate at Cornell University gave a brief talk this afternoon on her recent work investigating the cultural, practical, and conversational binaries that imagine geoengineering as distinctly, problematically separate from agriculture. She argued that the false dichotomy between issues of food security, land reform, and progressive farming must be deconstructed and replaced with a language of cooperation.
Climate-induced migration and climate engineering: Three notes on how to think through them together – Holly J. Buck
All scholarship on the relationship between climate migration and unrest (including Kelley et al’s paper) makes clear that there is always a complex of factors, which begs the question: can international law make decisions on conferring migrant or refugee status if someone is, say, a 30% climate migrant, a 20% economic migrant, and a 50% war refugee? The crux of the challenge is obvious. Governing climate engineering, with its uncertainty and difficulty in attributing consequences, is a similarly complex institutional design challenge.
