ASME: Can Engineering Change Our Climate for the Better?

"Climate engineering is the process of designing large-scale systems that have the potential to control climate and reduce the impact of climate change. This is a highly controversial topic because of the complexity of the systems involved and the possible negative effects upon the environment and human populations." (See also part 2)

van Vuuren, Detlef P.; et al. (2018): Alternative pathways to the 1.5 °C target reduce the need for negative emission technologies

van Vuuren, Detlef P.; Stehfest, Elke; Gernaat, David E. H. J.; van den Berg, Maarten; Bijl, David L.; Boer, Harmen Sytze de et al. (2018): Alternative pathways to the 1.5 °C target reduce the need for negative emission technologies. In Nature Climate change 5, p. 519. DOI: 10.1038/s41558-018-0119-8.

"The question arises whether alternative deep mitigation pathways exist. Here, using an integrated assessment model, we explore the impact of alternative pathways that include lifestyle change, additional reduction of non-CO2 greenhouse gases and more rapid electrification of energy demand based on renewable energy. Although these alternatives also face specific difficulties, they are found to significantly reduce the need for CDR, but not fully eliminate it. The alternatives offer a means to diversify transition pathways to meet the Paris Agreement targets, while simultaneously benefiting other sustainability goals."

Carbon Brief: World can limit global warming to 1.5C ‘without BECCS’

"It is possible to limit warming to 1.5C above pre-industrial temperatures without using negative emissions from bioenergy with carbon capture and storage (BECCS), new research says."

Earther: Chemtrails Aren't the Geoengineering Debate We Should Be Having (Because They Aren't Real)

"There’s a serious debate worth having, both on the science and technology itself and on the societal and policy implications. Unfortunately, in some corners of society valid concerns over the impacts of solar engineering have been overtaken by a different set of fears—various versions of the so-called chemtrails conspiracy theory. "

Saving Our World: How a last-ditch ‘planet-hacking’ plan could keep Earth habitable for longer

"The world is unlikely to hit the targets necessary to avoid catastrophic levels of climate change. Some think that as a last resort, we may need to temporarily cool the planet by modifying the skies. It wouldn’t solve the problem, but it might buy us time. This technology, called solar geoengineering, is so controversial that some experts think it could lead to global war. But just in case, a team of researchers at Harvard is planning to conduct one of the first outdoor geoengineering experiments."

Job: PhD position on environmental analysis of advanced biofuels (Norway)

Deadline: 25. April 2018

"However, biofuel systems are intrinsically complex, and their climate benefits are to be assessed on a case specific basis. Biofuel production systems are strictly connected to land management and land cover changes, thereby involving changes in a suite of biophysical mechanisms like surface energy fluxes and water balances that are strictly coupled to local temperature and precipitation changes. Further, climate impact analysis are seldom integrated with other sustainability indicators (e.g., the UN Sustainable Development Goals), and holistic approaches are essential to discern the interlinkages of the land-climate-energy nexus and guide future sustainable transitions."

Lempert, Robert J.; et al. (2018): Is Climate Restoration an Appropriate Climate Policy Goal?

Lempert, Robert J.; Marangoni, Giacomo; Keller, Klaus; Duke, Jessica (2018): Is Climate Restoration an Appropriate Climate Policy Goal? RAND Corporation (RR-2442-RC).

"This report offers an initial exploration of the concept of climate restoration — that is, approaches that seek to return atmospheric concentrations of greenhouse gases to preindustrial levels within one to two generations. Using a simple integrated assessment model, the analysis examines climate restoration through the lens of risk management under conditions of deep uncertainty, exploring the technology, economic, and policy conditions under which it might be possible to achieve various climate restoration goals and the conditions under which society might be better off with (rather than without) a climate restoration goal. This report also explores near-term actions that might help manage the risks of climate restoration."

Clean Technica: International Geoengineering Rules Are Urgently Needed, Researchers Argue

"As talk of geoengineering as a possible partial solution to anthropogenic climate change has grown over recent times, it has become an urgent need that there is a set of international rules put into place to govern such activities, some of those involved in the sector have begun arguing."

Carbon News: Solar geoengineering ‘still too uncertain’

"THE WORLD must urgently agree controls on solar geoengineering to weigh up its possible risks and benefits before deciding to go ahead, one expert says."
