Carnegie Science: Could “cocktail geoengineering” save the climate?

On Cao, Long; et al. (2017). "Geoengineering is a catch-all term that refers to various theoretical ideas for altering Earth’s energy balance to combat climate change. New research from an international team of atmospheric scientists published by Geophysical Research Letters investigates for the first time the possibility of using a “cocktail” of geoengineering tools to reduce changes in both temperature and precipitation caused by atmospheric greenhouse gases."

Cao, Long; et al. (2017): Simultaneous stabilization of global temperature and precipitation through cocktail geoengineering

Cao, Long; Duan, Lei; Bala, Govindasamy; Caldeira, Ken (2017): Simultaneous stabilization of global temperature and precipitation through cocktail geoengineering. In Geophys. Res. Lett. 37 (D6), p. 117. DOI: 10.1002/2017GL074281.

"Here we investigate the possibility of stabilizing both global mean temperature and precipitation simultaneously by combining two geoengineering approaches: stratospheric sulfate aerosol increase (SAI) that deflects sunlight to space and cirrus cloud thinning (CCT) that enables more longwave radiation to escape to space."

Newsweek: Climate Change and Geoengineering: Artificially Cooling Planet Earth by Thinning Cirrus Clouds

"Over recent decades, scientists from across the globe have been discussing the potential of geoengineering—the deliberate manipulation of the environment that could, in theory, cool the planet and help stabilize the climate."

Live Science: Cool the Planet? Geoengineering Is Easier Said Than Done

""If cirrus clouds behave like a blanket around the Earth, you're trying to get rid of that blanket," Lohmann, a professor of experimental atmospheric physics at ETH Zurich, told Live Science."

FCEA Blog: Carbon geoengineers: the debt collectors of the future

"Indeed, a recent report showed how none of the world’s top industries would be profitable if they paid for the true cost of natural capital. Granted, there has been some progress in the global decarbonization effort, but to date this has occurred on the fringes and in the absence of any enforceable targets to limit the total amount of atmospheric CO2."

Backdraft: Simon Nicholson on Climate Engineering

"“Although negotiators didn’t intend for this to be the case, now we’re kind of locked into a conversation where climate engineering is on the table,” says Nicholson. “If these [technologies] do start to come onto the table, then they can’t be used as cover for inaction. And that is perhaps the biggest political challenge in this space.”"
