Gernon, Thomas M.; et al. (2021): Global chemical weathering dominated by continental arcs since the mid-Palaeozoic

Gernon, Thomas M.; Hincks, Thea K.; Merdith, Andrew S.; Rohling, Eelco J.; Palmer, Martin R.; Foster, Gavin L. et al. (2021): Global chemical weathering dominated by continental arcs since the mid-Palaeozoic. In: Nat. Geosci. 28, S. 611. DOI: 10.1038/s41561-021-00806-0.

"Earth’s plate-tectonic activity regulates the carbon cycle and, hence, climate, via volcanic outgassing and silicate-rock weathering. Mountain building, arc–continent collisions and clustering of continents in the tropics have all been invoked as controlling the weathering flux, with arcs also acting as a major contributor of carbon dioxide to the atmosphere. However, these processes have largely been considered in isolation when in reality they are all tightly coupled. To properly account for interactions among these processes, and the inherent multi-million-year time lags at play in the Earth system, we need to characterize their complex interdependencies. Here we analyse these interdependencies over the past 400 million years using a Bayesian network to identify primary relationships, time lags and drivers of the global chemical weathering signal."

An, Soon‐Il; et al. (2021): Global cooling hiatus driven by an AMOC overshoot in a carbon dioxide removal scenario

An, Soon‐Il; Shin, Jongsoo; Yeh, Sang‐Wook; Son, Seok‐Woo; Kug, Jong‐Seong; Min, Seung‐Ki; Kim, Hyo‐Jeong (2021): Global cooling hiatus driven by an AMOC overshoot in a carbon dioxide removal scenario. In Earth’s Future. DOI: 10.1029/2021EF002165.

"Here, we performed an Earth system model simulation to explore the reversibility of earth climate, in which a CO2 concentration level gradually increases to 4 times CO2 of the present-day level and then returns to the present-day level."

Zickfeld, Kirsten; et al. (2021): Asymmetry in the climate–carbon cycle response to positive and negative CO2 emissions

Zickfeld, Kirsten; Azevedo, Deven; Mathesius, Sabine; Matthews, H. Damon (2021): Asymmetry in the climate–carbon cycle response to positive and negative CO2 emissions. In Nat. Clim. Chang., pp. 1–5. DOI: 10.1038/s41558-021-01061-2.

" It is commonly assumed that the climate–carbon cycle response to a negative CO2 emission is equal in magnitude and opposite in sign to the response to an equivalent positive CO2 emission. Here we test the hypothesis that this response is symmetric by forcing an Earth system model with positive and negative CO2 emission pulses of varying magnitude and applied from different climate states."

Belmonte, Beatriz A.; et al. (2021): A fuzzy optimization model for planning integrated terrestrial carbon management networks

Belmonte, Beatriz A.; Aviso, Kathleen B.; Benjamin, Michael Francis D.; Tan, Raymond R. (2021): A fuzzy optimization model for planning integrated terrestrial carbon management networks. In Clean Techn Environ Policy, pp. 1–13. DOI: 10.1007/s10098-021-02119-7.

"Although recent papers have reported the development of process integration models for optimizing carbon management networks based on either biochar application or enhanced weathering, none have reported models integrating these two NETs in the same system. To address this gap, a fuzzy mixed-integer linear programming model is developed that integrates biochar application and enhanced weathering for large-scale carbon sequestration."

Plazzotta, Maxime; et al. (2019): Impact of Solar Radiation Modification on Allowable CO 2 Emissions: What Can We Learn From Multimodel Simulations?

Plazzotta, Maxime; Séférian, Roland; Douville, Hervé (2019): Impact of Solar Radiation Modification on Allowable CO 2 Emissions: What Can We Learn From Multimodel Simulations? In Earth’s Future 7 (6), pp. 664–676. DOI: 10.1029/2019EF001165.

"Here we use the results of six Earth system models simulating a continuous stratospheric injection of 5 Tg of sulfur dioxide per year between 2020 and 2069 under the representative concentration pathways 4.5 to investigate the impact of SRM on land and ocean carbon uptake."

Visioni, Daniele; et al. (2021): Identifying the sources of uncertainty in climate model simulations of solar radiation modification with the G6sulfur and G6solar Geoengineering Model Intercomparison Project (GeoMIP) simulations

Visioni, Daniele; MacMartin, Douglas G.; Kravitz, Ben; Boucher, Olivier; Jones, Andy; Lurton, Thibaut et al. (2021): Identifying the sources of uncertainty in climate model simulations of solar radiation modification with the G6sulfur and G6solar Geoengineering Model Intercomparison Project (GeoMIP) simulations. Preprint. In Atmos. Chem. Phys. DOI: 10.5194/acp-2021-133.

"We present here results from the Geoengineering Model Intercomparison Project (GeoMIP) simulations for the experiment G6sulfur and G6solar for six Earth System Models participating in the Climate Model Intercomparison Project (CMIP) Phase 6. The aim of the experiments is to reduce the warming from that resulting from a high-tier emission scenario (Shared Socioeconomic Pathways SSP5-8.5) to that resulting from a medium-tier emission scenario (SSP2-4.5)."
