SBS: The Crazy Climate Technofix

"Earth’s climate has been edging towards a scene usually reserved for a post-apocalyptic movie. Some posit geoengineering as a radical fix to climate change. Others say the risks are too high and its proponents mad. Welcome to the debate where science fiction meets climate science."

CfP: Crutzen +10: Reflecting upon 10 years of geoengineering research

Deadline: 30. July 2016

"The year 2016 marks the 10 year anniversary of Nobel laureate Paul Crutzen's seminal 2006 contribution on geoengineering, “Albedo enhancement by stratospheric sulfur injection: A contribution to solve a policy dilemma?” Crutzen’s paper in climatic change sparked an unprecedented surge of academic, public, and political interest in geoengineering. AGU’s journal Earth’s Future invites leading experts in the field of geoengineering research to contribute brief reflections (2 - 5 pages) on the development of the discussion over the past decade and to consider where it may be going in the next 10 years."

Matthews, M.; et al. (2016): Laser vaporization of cirrus-like ice particles with secondary ice multiplication

Matthews, M.; Pomel, F.; Wender, C.; Kiselev, A.; Duft, D.; Kasparian, J. et al. (2016): Laser vaporization of cirrus-like ice particles with secondary ice multiplication. In Science Advances 2 (5), e1501912-e1501912. DOI 10.1126/sciadv.1501912.

"We investigate the interaction of ultrashort laser filaments with individual 90-μm ice particles, representative of cirrus particles. The ice particles fragment under laser illumination. By monitoring the evolution of the corresponding ice/vapor system at up to 140,000 frames per second over 30 ms, we conclude that a shockwave vaporization supersaturates the neighboring region relative to ice, allowing the nucleation and growth of new ice particles, supported by laser-induced plasma photochemistry."

Kravitz, Ben; et al. (2016): Geoengineering as a design problem

Kravitz, Ben; MacMartin, Douglas G.; Wang, Hailong; Rasch, Philip J. (2016): Geoengineering as a design problem. In Earth Syst. Dynam. 7 (2), pp. 469–497. DOI 10.5194/esd-7-469-2016.

"Here we turn this approach around by first choosing example climate objectives and then designing a strategy to meet those objectives in climate models. There are four essential criteria for designing a strategy: (i) an explicit specification of the objectives, (ii) defining what climate forcing agents to modify so the objectives are met, (iii) a method for managing uncertainties, and (iv) independent verification of the strategy in an evaluation model."

Treehugger: Study evaluates geo-engineering to reduce global warming by increasing aerosol levels

"Now a study by Anton Laakso of the Finnish Meteorological Institute proves that even if a proposal so wrought with potential unintended consequences could get approved, it can't fix our global warming problem. The more aerosols added to the atmosphere, the less effective the cooling."

Mercury: University of Tasmania professors given fellowships from Australian Research Council to tackle climate change

"TWO University of Tasmania professors have today been honoured with Australian Laureate Fellowships from the Australian Research Council. [...] Professor Boyd will evaluate the feasibility of boosting carbon dioxide removal by Southern Ocean microbes to offset climate change, to provide a framework for future research and inform international policy on the use of geoengineering — large-scale intervention in the Earth’s natural systems — to mitigate against climate change."

Reporting Climate Science: Atmospheric Aerosols Can Cool Climate

Media response to Laakso, A.; et al. (2016). "Climate engineering using atmospheric aerosols could lead to significant cooling to help offset climate change, according to a new study – but it would still mean greenhouse gas emissions would need to be curbed. "
