the guardian: Silver linings: the climate scientist who records cloud behaviour

"Clouds cool the planet by reflecting solar energy back to space and also trap heat and radiate it back to Earth. In a Yale Environment 360 interview, physicist Kate Marvel discusses the double-edged effect clouds have on rising temperatures."

Yale Environment 360: Investigating the Enigma of Clouds and Climate Change

"With geoengineering, I’m always very concerned because if I want to do an experiment on human subjects, as a university researcher, I have to go in front of a review board and convince them that all of my human subjects have given informed consent to participate in this experiment. And with a lot of geo-engineering experiments, I worry about how that consent is going to be obtained."

The Wire: The Questionable Future of Geoengineering

"While the nascent field of geoengineering attracts an increasing amount of attention, there remains much trepidation with how it could potentially affect current efforts to limit carbon and other greenhouse gas emissions."

Peters, Glen P.; Geden, Oliver (2017): Catalysing a political shift from low to negative carbon

Peters, Glen P.; Geden, Oliver (2017): Catalysing a political shift from low to negative carbon. In Nature Climate change 4, p. 850. DOI: 10.1038/nclimate3369.

"Policymakers are beginning to understand the scale of carbon dioxide removal that is required to keep global warming “well below 2 °C”. This understanding must now be translated into policies that give business the incentive to research, develop and deploy the required technologies."

Parson, Edward A. (2017): Starting the Dialogue on Climate Engineering Governance: A World Commission

Parson, Edward A. (2017): Starting the Dialogue on Climate Engineering Governance: A World Commission. Centre for International Governance Innovation (CIGI) (Fixing Climate Governance Series Policy Brief, 8).

"The needed international dialogue on geoengineering governance will have broad international participation; engage high-level expertise in international policy and institutions; draw closely on parallel advances in scientific knowledge and technical capability, while keeping governance the central focus; and facilitate open, exploratory investigations of governance needs and potential responses, rather than pursue specific decisions, at least in initial stages. Present institutions are not well equipped to support these needs. A promising first step would be to establish a world commission on climate engineering or similar consultative body, with high-level political authorization, an appropriately broad mandate, adequate resources and wide participation."

Energy Collective: The Self-Sustaining Climate Remedy

"An ocean thermal energy conversion (OTEC) resource map like the one above, where the palate ranges from red to yellow to indicate ocean surface temperatures ranging from 28oC or above down to 22oC is essentially a map of the impact of global warming. Recognition of the problem is the first step towards its solution and from there you can ascertain where to allocate the resources necessary to realise your solution."

PLOS Blog: Geoengineering and Synthetic Biology

"This September, as part of their annual symposium, EUSynBioS will hold an Open Discussion on the topic, “Synthetic Biology and Environmental Engineering”, at the National Center for Biotechnology, Madrid, Spain. They will host experts in the field to talk about the science and the more difficult aspects of public acceptance and bioethics surrounding geoengineering and synthetic biology."

Parson, Edward A. (2017): Opinion. Climate policymakers and assessments must get serious about climate engineering

Parson, Edward A. (2017): Opinion. Climate policymakers and assessments must get serious about climate engineering. In PNAS 4, p. 201713456. DOI: 10.1073/pnas.1713456114.

"Furthermore, the large-scale use of CE is probably essential for achieving prudent climate-change limits, including the Paris target of limiting the average global temperature rise to 1.5–2.0 °C. This conclusion appears unavoidable based on the current level of global greenhouse-gas emissions and the long time-constants of the climate system and the human energy system (e.g., the long atmospheric lifetime of carbon dioxide and the time required for large-scale deployment of new technologies). CE may also enable integrated climate-response strategies that reduce risks in ways not otherwise achievable."
