Methane, volcanoes, and the end of the world - Guest Post - Duncan McLaren - University of Lancaster. "The idea of ‘climate emergency’ has been a hot one in the ethics of geoengineering for a number of years, and got a lot of attention last week at the climate engineering conference (CEC14) in Berlin."

"It was a great story, writes Andrew Lockley - scientists signing up to a 'Berlin Declaration' imposing an effective 'test ban' on outdoor geoengineering experiments. Except there was no declaration, and scientists never agreed to it. The world's media got it completely wrong, yet the mud will stick - and may cause severe harm in the fight against climate change."

"For years, Dr. Ken Caldeira's interest in planet hacking made him a curious outlier in his field. A highly respected atmospheric scientist, he also describes himself as a "reluctant advocate" of researching solar geoengineering—that is, large-scale efforts to artificially manage the amount of sunlight entering the atmosphere, in order to cool off the globe."
