Heutel, Garth; et al. (2015): Climate Engineering Economics

Heutel, Garth; Moreno-Cruz, Juan; Ricke, Katharine (2015): Climate Engineering Economics. Cambridge, MA (NBER Working Paper Series, 21711).

"This article reviews and evaluates the nascent literature on the economics of climate engineering. [...] We review the science and engineering characteristics of these technologies and analyze the implications of those characteristics on economic policy design. We discuss optimal policy and carbon price, inter-regional and inter-generational equity issues, strategic interaction in the design of international environmental agreements, and the sources of risk and uncertainty surrounding these technologies."

The Conversation: Blocking out the sun won’t fix climate change – but it could buy us time

"Could we directly engineer the climate and refreeze the poles? The answer is probably yes, and it could be a cheap thing to achieve – maybe costing only a few billion dollars a year. But doing this – or even just talking about it – is controversial."

Hourdequin, Marion (2015): The ethics of geoengineering

Hourdequin, Marion (2015): The ethics of geoengineering. In The Philosophers' Magazine (71), pp. 44–50. DOI: 10.5840/tpm201571101 

"What is distinctive about contemporary climate change is that it is human caused. significant in magnitude, and exceptionally rapid in relation to past climatic shifts. Not only does this pose challenges to human society; it is transforming ecosystems and outpacing the ability of individual species to adapt to changing conditions."

Tech Insider: Bill Nye says bubbling air into Earth's oceans might save the planet from ourselves

"In the chat, Nye said he believes that geoengineering — a family of techniques to hack the environment — could be a game-changer for combating climate change."

Energy Post: Interview Hoesung Lee, new Chairman IPCC: “There is enormous value in carbon capture and storage”

"The new chairman of the IPCC, Hoesung Lee, wants to interact more with the energy industry. [...] 'The Fifth Assessment Report found that limited evidence was available to assess solar radiation management and carbon dioxide removal and their impact on the climate system.'"

Scientific American: Meeting a Global Carbon Limit Is Cheaper Than Avoiding One

"Even with innovation and scaling up, we may at some point have to deploy “direct-air capture” technology, which pulls carbon dioxide out of the atmosphere. That would be expensive, but Klaus Lackner, an engineering professor at Arizona State University, is confident that the cost could be brought down to $30 a ton with volume manufacturing."

dpa international: Plan B: Hacking the climate

"In a laboratory in the US Pacific north-west, scientists are working on what could one day become a new, and controversial, weapon to fight global warming: clouds. Misting ocean clouds with saltwater could multiply the water droplets inside, the theory goes, "brightening" clouds to make them reflect more sunlight away from the earth."

Quaas, Johannes (2015): Approaches to Observe Anthropogenic Aerosol-Cloud Interactions

Quaas, Johannes (2015): Approaches to Observe Anthropogenic Aerosol-Cloud Interactions. In Curr Clim Change Rep 1 (4), pp. 297–304. DOI: 10.1007/s40641-015-0028-0 

"Anthropogenic aerosol particles exert an—quantitatively very uncertain—effective radiative forcing due to aerosol-cloud interactions via an immediate altering of cloud albedo on the one hand and via rapid adjustments by alteration of cloud processes and by changes in thermodynamic profiles on the other hand. Large variability in cloud cover and properties and the therefore low signal-to-noise ratio for aerosol-induced perturbations hamper the identification of effects in observations."
