Phys.org: Glacial geoengineering—the key to slowing sea level rise?

"The rapid collapse of some of the world's biggest glaciers due to climate change will have devastating consequences for our planet's coastlines due to sea level rise. Compounding this issue is the fact that many of these coastlines are heavily populated and developed. A recent proposal, first reported in The Atlantic, aims to avert potential catastrophe by turning to geoengineering through the construction of massive underwater walls, called sills, which would be built where glaciers meet the ocean in Antarctica and Greenland."

Yosef, Gil; et al. (2018): Large-scale semi-arid afforestation can enhance precipitation and carbon sequestration potential

Yosef, Gil; Walko, Robert; Avisar, Roni; Tatarinov, Fedor; Rotenberg, Eyal; Yakir, Dan (2018): Large-scale semi-arid afforestation can enhance precipitation and carbon sequestration potential. In Scientific reports 8 (1), p. 996. DOI: 10.1038/s41598-018-19265-6.

"Here, we use a Global Climate Model to provide a process-based demonstration that implementing measured characteristics of a successful semi-arid afforestation system (2000 ha, ~300 mm mean annual precipitation) over large areas (~200 million ha) of similar precipitation levels in the Sahel and North Australia leads to the weakening and shifting of regional low-level jets, enhancing moisture penetration and precipitation (+0.8 ± 0.1 mm d−1 over the Sahel and +0.4 ± 0.1 mm d−1 over North Australia), influencing areas larger than the original afforestation.

Keller, David P. (2018): Marine Climate Engineering

Keller, David P. (2018): Marine Climate Engineering. In Markus Salomon, Till Markus (Eds.): Handbook on Marine Environment Protection. Science, Impacts and Sustainable Management. 1st edition 2018. Cham: Springer International Publishing, pp. 261–276.

"In this chapter an overview is given of the proposed climate engineering methods that involve the direct manipulation of marine systems. This includes methods that enhance the ocean’s natural physical, chemical, and biological CO2 sequestration pathways, as well as purely technical ones that either use the ocean as a carbon storage reservoir or alter it’s properties to affect the Earth’s radiation budget."

TeCake: The Volcano that can aid to reduce global warming, says NASA

"Alan Robock, a climatologist at Rutgers University, who studies volcanic eruptions and has been involved in discussions about the rapid-response project, says in a statement, “This is important if we’re ever going to do geoengineering.” He continues further, “but even if there were no such thing as geoengineering, it’s still important to understand how volcanoes affect climate.”"

Price, Paul; et al. (2018): A Post-Paris Literature Review of Negative Emissions Technology, and Potential for Ireland

Price, Paul; Mcgeever, Alwynne; Jones, Mike; Mcmullin, Barry (2018): A Post-Paris Literature Review of Negative Emissions Technology, and Potential for Ireland. Dublin City University; Trinity College Dublin (Working Paper).

"This report, the first interim deliverable from the IE-NETs project, presents a comprehensive review of the existing international and national literature on the potential forms of negative emissions technology (NET), with a particular focus on technology options suitable for deployment in Ireland. It includes an executive summary which presents an overview and key results from the full review. ie-nets is a two-year research project, funded by the Environmental Protection Agency of Ireland (EPA) Research Programme 2014-2020 (grant number 2016-CCRPMS.36). The project is building Irish research capacity and contributing to national policy in the emerging area of Negative Emissions Technology/Carbon Dioxide Removal."

EASAC (2018): Negative emission technologies: What role in meeting Paris Agreement targets?

EASAC (2018): Negative emission technologies: What role in meeting Paris Agreement targets? Halle (Saale) (EASAC policy report, 35).

"In a new report by the European Academies’ Science Advisory Council (EASAC), senior scientists from across Europe have evaluated the potential contribution of negative emission technologies (NETs) to allow humanity to meet the Paris Agreement’s targets of avoiding dangerous climate change. They find that NETs have “limited realistic potential” to halt increases in the concentration of greenhouse gases in the atmosphere at the scale envisioned in the Intergovernmental Panel on Climate Change (IPCC) scenarios."

earth.com: The safest climate engineering strategies to reduce extreme temps

"Researchers have found that large-scale, international efforts to regulate the climate by modifying properties of the land surface in highly populated and agricultural areas could be very successful. The study from the University of New South Wales suggests that this type of climate engineering could reduce extreme temperatures by up to 3 degrees Celsius in North America, Europe, and Asia."

Reuters: Shinier cities - and fields - could cut extreme heat risk: scientists

"Making cities and farm fields more reflective - including by painting buildings white or leaving more land unploughed after harvests - could reduce extreme heat by up to 3 degrees Celsius in areas where the techniques are used, scientists say. While such measures would not lower global temperatures - which are rising as a result of climate change - such simple changes could provide substantial local or regional relief on the hottest days, according to research published this week in the journal Nature Geoscience."

Euraktiv: Scientists dismiss ‘geo-engineering’ to stop climate change

"“None” of the negative emission technologies currently available – including forest carbon sinks and other geo-engineering techniques – have the potential to deliver CO2 removals at the scale and rate needed to keep global warming below 2°C, European scientists have warned in a new report out today"
