Wang, Seaver, and Zeke Hausfather. 2020: “ESD Reviews: Mechanisms, Evidence, and Impacts of Climate Tipping Elements.”

Wang, Seaver, and Zeke Hausfather. 2020: “ESD Reviews: Mechanisms, Evidence, and Impacts of Climate Tipping Elements.” Earth System Dynamics. https://doi.org/10.5194/esd-2020-16.

‌"Here we review mechanisms, predictions, impacts, and knowledge gaps associated with ten notable climate tipping elements. We also evaluate which tipping elements are more imminent and whether shifts will likely manifest rapidly or over longer timescales."

Haque, Fatima; et al. 2020: “CO2 Sequestration by Wollastonite-Amended Agricultural Soils – An Ontario Field Study.”

Haque, Fatima, Rafael M. Santos, and Yi Wai Chiang. 2020: “CO2 Sequestration by Wollastonite-Amended Agricultural Soils – An Ontario Field Study.” International Journal of Greenhouse Gas Control 97 (June 2020): 103017. https://doi.org/10.1016/j.ijggc.2020.103017.

"In the present study, wollastonite-amended soils were collected from three commercial-scale fields located in Ontario: a leafy vegetables farm in the town of Paris (Field 1); a potato farm in the settlement of Alliston (Field 2); and a soybean farm in the city of Woodstock (Field 3). Chemical and mineralogical assessments of these soils were conducted to determine their carbonate content and the fate of the wollastonite."

de Oliveira Garcia, Wagner; et al. 2020: “Impacts of Enhanced Weathering on Biomass Production for Negative Emission Technologies and Soil Hydrology.”

de Oliveira Garcia, Wagner, Thorben Amann, Jens Hartmann, Kristine Karstens, Alexander Popp, Lena R. Boysen, Pete Smith, and Daniel Goll. 2020: “Impacts of Enhanced Weathering on Biomass Production for Negative Emission Technologies and Soil Hydrology.” Biogeosciences 17 (7): 2107–33. https://doi.org/10.5194/bg-17-2107-2020.

‌"Here, we investigate the deployment of enhanced weathering (EW) to supply nutrients to areas of afforestation–reforestation and naturally growing forests (AR) and bioenergy grasses (BG) that are deficient in phosphorus (P), besides the impacts on soil hydrology. Using stoichiometric ratios and biomass estimates from two established vegetation models, we calculated the nutrient demand of AR and BG."

McLaren, Duncan, and Nils Markusson. 2020: “The Co-Evolution of Technological Promises, Modelling, Policies and Climate Change Targets.”

"The nature and framing of climate targets in international politics has changed substantially since their early expressions in the 1980s. Here, we describe their evolution in five phases—from ‘climate stabilization’ to specific ‘temperature outcomes’—co-evolving with wider climate politics and policy, modelling methods and scenarios, and technological promises (from nuclear power to carbon removal)."
