„Film maker Nick Breeze has conducted a series of interviews with experts on ‚geo-engineering‘ to forestall runaway global warming. Here he presents the distilled wisdom from his meetings – and concludes that we should at least be experimenting with the techniques, and studying their impacts.“
„Myriad forms of geoengineering — harnessing Earth’s natural systems for planet-wide change — are being investigated by scientists, trying to utilise ants and volcanic eruptions, writes Erin Biba.“

„After carefully assessing the benefits and risk of geoengineering, one is faced with this dilemma: should there be a role for geoengineering in reversing climate change?“

In Atmos. Chem. Phys. Discuss. 14 (16), pp. 32393–32425. DOI 10.5194/acpd-14-32393-2014.
„Simulations from a multi-model ensemble for the RCP4.5 climate change scenario for the 21st century, and for two solar radiation management schemes (stratospheric sulfate injection, G3, and marine cloud brightening, G3SSCE) have been analyzed in terms of changes in the mean and extremes for surface air temperature and precipitation.„
Response to Iles, Carley E.; Hegerl, Gabriele C. (2014). „Designers of geoengineering schemes should be aware that climate models underestimate changes in precipitation after volcanic eruptions, according to researchers in the UK.“

„We examine the precipitation response to volcanic eruptions in the Coupled Model Intercomparison Project Phase 5 (CMIP5) historical simulations compared to three observational datasets, including one with ocean coverage.“
Comment on Fuss, Sabine; et al. (2014). „BECCS, which combines bio-energy production (biomass fuel-power stations, pulp mills and bio-fuel plants) with carbon capture and storage technology, has the potential to generate “negative emissions” that could help society avoid exceeding critical thresholds in this century and beyond.“

„Bioenergy with carbon capture and storage could be used to remove carbon dioxide from the atmosphere. However, its credibility as a climate change mitigation option is unproven and its widespread deployment in climate stabilization scenarios might become a dangerous distraction.“

„In this paper we examine a wide variety of policy documents from different countries, international organizations and NGOs to gain insights into how geoengineering is perceived at the policy level.“
