„This reality prompted a February report from the highly respected National Academy of Sciences that endorsed research into what’s loosely known as geoengineering. […] Given that global warming is an existential threat, this is a responsible and necessary position.“
„Computer modellers have investigated the proposals‘ potential effects and some laboratory work has been done, but there is, as yet, nothing approaching a socio-technical system capable of delivering any controlled geoengineering effect. Additionally these ideas remain highly controversial.„
„The giant coal power station at Drax in Yorkshire, with its 12 cooling towers, is one of the world’s largest greenhouse gas emitters. It sends some 23 million tonnes of carbon dioxide up its stacks each year, while supplying up to a tenth of the UK’s power.“
On climate wars and CE. „In this episode of Generation Anthropocene, scientists explore the link between rising temperatures and aggression“
Press release to Lu, Lu; et al. (2015). „Cleaning up municipal and industrial wastewater can be dirty business, but engineers at the University of Colorado Boulder have developed an innovative wastewater treatment process that not only mitigates carbon dioxide (CO2) emissions, but actively captures greenhouse gases as well.“

„We investigate the impact of a future climate and a potential geoengineering scheme on the number of crop failures in two regions, Northeastern China and West Africa. Climate change associated with a doubling of atmospheric carbon dioxide increases the number of crop failures in Northeastern China while reducing the number of crop failures in West Africa“
„Study finds that ‚technofixes‘ won’t be enough to save the planet’s oceans in a world where CO2 emissions continued to climb.“
Media response to Mathesius, Sabine; et al. (2015). „Researchers have demonstrated that even if a geoengineering solution to CO2 emissions could be found, it wouldn’t be enough to save the oceans.“

„To assess the extent to which CDR might eliminate the long-term consequences of anthropogenic CO2 emissions in the marine environment, we simulate the effect of two massive CDR interventions with CO2 extraction rates of 5 GtC yr−1 and 25 GtC yr−1, respectively, while CO2 emissions follow the extended RCP8.5 pathway.“
