„Geoengineering technologies like Solar Radiation Management have the potential to mitigate risks from climate change, while at the same time posing risks of their own. The current lack of international norms on acceptable research practices may well be holding back safe exploration of climate engineering options.“
Fuss, Sabine; et al. (2016): Research priorities for negative emissions
Fuss, Sabine; Jones, Chris D.; Kraxner, Florian; Peters, Glen P.; Smith, P.; Tavoni, Massimo et al. (2016): Research priorities for negative emissions. In Environ. Res. Lett. 11 (11), p.[nbsp]115007. DOI: 10.1088/1748-9326/11/11/115007.
„While there are few pathways to 2 °C that do not rely on negative emissions, 1.5 °C scenarios are barely conceivable without them. Building on previous assessments of NETs, we identify some urgent research needs to provide a more complete picture for reaching ambitious climate targets, and the role that NETs can play in reaching them.“

„Temperatures are now so high at the north pole that scientists are contemplating radical schemes to avoid catastrophe“

„Researchers look into the future of the far North for clues to save species and maybe even bring back sea ice.“

„The European Union aims at reducing its greenhouse gas emissions in 2050 by 80-95% in order to prevent climate change. In this Policy Brief we analyse the potential role of negative-emissions technology in reducing these emissions.“
Quaas, Martin F.; et al. (2017): Are there reasons against open-ended research into solar radiation management? A model of intergenerational decision-making under uncertainty
Quaas, Martin F.; Quaas, Johannes; Rickels, Wilfried; Boucher, Olivier (2017): Are there reasons against open-ended research into solar radiation management? A model of intergenerational decision-making under uncertainty. In Journal of Environmental Economics and Management. DOI: 10.1016/j.jeem.2017.02.002.
„We propose a stylized model of intergenerational decision making on SRM research, greenhouse-gas abatement and SRM deployment, under uncertainties about (a) the extent of future climate damage and (b) effectiveness and potential harmful side-effects of SRM. Open-ended research may reveal either that SRM effectively reduces climate damage, or that it would cause more harm than benefits. We find that SRM research increases the likelihood of deployment (“slippery slope”), and derive conditions that it decreases abatement effort in expectation (“moral hazard”).“

Reynolds, Jesse (2016): Solar Climate Engineering, Law, and Regulation. In Roger Brownsword, Eloise Scotford, Karen Yeung (Eds.): The Oxford handbook of the law and regulation of technology. Oxford: Oxford University Press.
„This chapter offers an introduction to solar climate engineering, and explores its potential, risks, and legal and regulatory challenges. It also contextualizes these proposals with respect to other emerging technologies and the broader socio-political milieu. The chapter discusses the contours of existing and potential regulation, particularly at the international level. These aspects include regulatory rationales, diverse characteristics of proposed regulatory regimes, difficulties in defining the regulatory target, and the management of uncertainty through precaution.“
Mathias, Jean-Denis; et al. (2017): On our rapidly shrinking capacity to comply with the planetary boundaries on climate change
Mathias, Jean-Denis; Anderies, John M.; Janssen, Marco A. (2017): On our rapidly shrinking capacity to comply with the planetary boundaries on climate change. In Scientific reports 7, p.[nbsp]42061. DOI: 10.1038/srep42061.
„Here, we use the DICE model to analyze the set of adaptive climate policies that comply with the two planetary boundaries related to climate change: (1) staying below a CO2 concentration of 550 ppm until 2100 and (2) returning to 350 ppm in 2100. Our results enable decision makers to assess the following milestones: (1) a minimum of 33% reduction of CO2 emissions by 2055 in order to stay below 550 ppm by 2100 (this milestone goes up to 46% in the case of delayed policies); and (2) carbon neutrality and the effective implementation of innovative geoengineering technologies (10% negative emissions) before 2060 in order to return to 350 ppm in 2100, under the assumption of getting out of the baseline scenario without delay.“
