MIT Technology Review: One man’s two-decade quest to suck greenhouse gas out of the sky

"Lackner and his colleagues at Arizona State University’s Center for Negative Carbon Emissions have built a simple machine with a grand purpose: capturing and recycling carbon dioxide to ease the effects of climate change. He envisions forests of them stretching across the countryside, sucking up billions of tons of it from the atmosphere."

Nbcnews: Wallace Smith Broecker, the 'grandfather' of climate science, leaves a final warning for Earth

"It was time for humankind and the world’s scientific community to begin to seriously study more extreme solutions to the climate crisis, Broecker said. That included creating a massive solar shield in the Earth’s atmosphere, a tactic known variously as 'geoengineering,' 'the sulfur solution,' 'solar radiation management' and the 'Pinatubo Strategy.'"

Futurenow: How artificially brightened clouds could stop climate change

"In truth, we already know the action needed to reduce man-made climate change: a rapid reduction in greenhouse gas emissions, replacing fossil fuels with renewable energy. According to the recent Intergovernmental Panel for Climate Change (IPCC) report, the world has just 12 years in which to cut emissions by half, and 32 years (by 2050) to get net emissions down to zero."

C2G2: How to legitimately govern geoengineering

"Most people recognize the necessity of governing geoengineering. There is a clear need for an international institution (or a set of institutions) that can help regulate research, coordinate development, and either facilitate or prohibit future deployment of the different geoengineering technologies. Of course, we don’t want just any old institution making decisions about geoengineering – we want a legitimate institution making such decisions. But what would it take for a geoengineering governance institution to be legitimate?"

Gwagner: Solar Geoengineering Research Zotero Library

"Ever since Paul Crutzen broke a long-standing taboo on solar geoengineering research with an essay published in Climatic Change in 2006, the number of publications in the field has increased rapidly. By now there are over 1,500. We have attempted here to collect and catalog them in an easily accessible Zotero database."

Science: New way to turn carbon dioxide into coal could ‘rewind the emissions clock’

"If humans hope to limit climate change to just 2°C of warming, we’ve got a lot of work to do, scientists say: reducing emissions, planting trees, and scrubbing carbon dioxide (CO2) from the skies with the latest technologies. Now, a new process can convert gaseous CO2—the product of burning fossil fuels—into solid carbon at room temperature, using only a trickle of electricity. But getting it to work on a planet-wide scale will be a formidable challenge."
