„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.“
„Adam Walton and guests discuss one of the more radical and controversial suggestions for preventing global warming, geoengineering the planet’s atmosphere and climate.“

„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.“
On Oliver Morton’s book. „The Planet Remade, journalist Oliver Morton presents the need for a real-life “Greenfinger” to cool the planet. Curbing humankind’s fossil fuel habit within the next few decades is just too tall an order considering today’s lackluster energy alternatives, he argues.“
Interview with Richard Somerville, Lisa Levin, and Margaret Leinen on climate change and CE. „Thousands of world leaders and scientists will meet in Paris next month for the United Nations conference on climate change. A key goal of the summit is to reach agreement on limiting or reducing greenhouse gas emissions. Among those attending the Paris conference will be Margaret Leinen, director of Scripps Institution of Oceanography, and Scripps scientists Richard Somerville and Lisa Levin.“

„In order to study the conduct, observation, or defence associated with such attacks, a range of potentially practical weapon and defence technologies are discussed. These are: altering the radiation budget of a planet so as to substantially change its temperature; introducing invasive species to transform the biogeochemistry; and using orbital perturbations of comets and asteroids to cause collisions, or to move the planet to an unstable or uninhabitable orbit.“
Hansson, Anders; Rayner, Steve; Wibeck, Victoria (2015): Climate engineering. In Karin Bäckstrand, Eva Lövbrand (Eds.): Research handbook on climate governance. Cheltenham: Edward Elgar Publishing, pp.[nbsp]411–422.
„This chapter will discuss governance challenges for calimte engineering, and propose some high-level principles for the governance of the field of climate engineering. Further, the chapter outlines recurrent ways in which climate engineering has been framed in public and scientific discourse and discusses how such framings may influence the future of climate engineering.“
Buckholtz, Michelle Carolina (2015): Decision analysis for climate engineering research. University of Texas at Austin.
Masters thesis. „This report identifies the unique characteristics which make climate engineering an important tool in the portfolio of strategies for managing climate change risks. Next potential benefits and costs associated with the technology are explored. The largest ethical objections to research and use of the technology are discussed and presented in a more consistent framework than found in existing literature.“

„Here, we present results of a standard SRM modelling experiment in which the incoming solar irradiance is reduced to offset the global mean warming induced by a quadrupling of atmospheric carbon dioxide. For the first time in an atmosphere–ocean coupled climate model, we include atmospheric composition feedbacks such as ozone changes under this scenario.„
Nye, Bill; Powell, Corey S. (2015): Unstoppable. Harnessing science to change the world. New York: St. Martin’s Press.
With a chapter (pp 53-66) „In UNSTOPPABLE, Bill Nye crystallizes and expands the message for which he is best known and beloved. That message is that with a combination of optimism and scientific curiosity, all obstacles become opportunities, and the possibilities of our world become limitless. With a scientist’s thirst for knowledge and an engineer’s vision of what can be, Bill Nye sees today’s environmental issues not as insurmountable, depressing problems but as chances for our society to rise to the challenge and create a cleaner, healthier, smarter world.“
