Varney, Rebecca M.; et al. (2020): A spatial emergent constraint on the sensitivity of soil carbon turnover to global warming

Varney, Rebecca M.; Chadburn, Sarah E.; Friedlingstein, Pierre; Burke, Eleanor J.; Koven, Charles D.; Hugelius, Gustaf; Cox, Peter M. (2020): A spatial emergent constraint on the sensitivity of soil carbon turnover to global warming. In Nat Comms 11 (1), p. 5544. DOI: 10.1038/s41467-020-19208-8.

"Here, we present a constraint on ΔCs,τ, which makes use of current heterotrophic respiration and the spatial variability of τs inferred from observations. This spatial emergent constraint allows us to halve the uncertainty in ΔCs,τ at 2 °C to −232 ± 52 PgC."

Phys.org: Warming of 2 C would release billions of tons of soil carbon

"The new international research study, led by the University of Exeter, reveals the sensitivity of soil carbon turnover to global warming and subsequently halves uncertainty about this in future climate change projections."

Wang, Jing; et al. (2020): Large Chinese land carbon sink estimated from atmospheric carbon dioxide data

Wang, Jing; Feng, Liang; Palmer, Paul I.; Liu, Yi; Fang, Shuangxi; Bösch, Hartmut et al. (2020): Large Chinese land carbon sink estimated from atmospheric carbon dioxide data. In Nature 586 (7831), pp. 720–723. DOI: 10.1038/s41586-020-2849-9.

"Here we present recently available data on the atmospheric mole fraction of CO2, measured from six sites across China during 2009 to 2016. Using these data, we estimate a mean Chinese land biosphere sink of −1.11 ± 0.38 petagrams of carbon per year during 2010 to 2016, equivalent to about 45 per cent of our estimate of annual Chinese anthropogenic emissions over that period."

The Millbrook Independent: The Futility of Soil Carbon Sequestration

"For a long time, farmers have realized that soil organic matter improves the quality of soils, by improving water-hold capacity, friability, and nutrient content. But, however we do it—fertilization, irrigation, manuring, reduced tillage, and planting cover crops—increasing soil organic matter doesn’t look like such a good idea to mitigate climate change. The chemistry of humus substances includes a substantial amount of nitrogen and phosphorus that will limit our efforts."

Strassburg, Bernardo B. N.; et al. (2020): Global priority areas for ecosystem restoration

Strassburg, Bernardo B. N.; Iribarrem, Alvaro; Beyer, Hawthorne L.; Cordeiro, Carlos Leandro; Crouzeilles, Renato; Jakovac, Catarina C. et al. (2020): Global priority areas for ecosystem restoration. In Nature. DOI: 10.1038/s41586-020-2784-9.

"Here we develop and apply a multicriteria optimization approach that identifies priority areas for restoration across all terrestrial biomes, and estimates their benefits and costs. We find that restoring 15% of converted lands in priority areas could avoid 60% of expected extinctions while sequestering 299 gigatonnes of CO2—30% of the total CO2 increase in the atmosphere since the Industrial Revolution."

World Resources Institute: INSIDER: Further Explanation on the Potential Contribution of Soil Carbon Sequestration on Working Agricultural Lands to Climate Change Mitigation

"Implemented in the right way, preserving the huge, existing reservoirs of vegetative and soil carbon in the world’s remaining forests and woody savannas by boosting productivity on existing agricultural land (a land sparing strategy) is the largest, potential climate mitigation prize of regenerative and other agricultural practices."

Podcast: Clean Technica: Machine Learning + CleanTech + Climate Risks, Part II — CleanTech Talk Podcast

"Mike then moved the conversation toward geoengineering, which Paul believes needs more attention. Mike sees a fundamental problem in pretending like the world could geoengineer its way out of climate change without causing other problems, whereas Paul thinks there is a balance to be found."

Gosnell, Hannah; et al. (2020): Climate change mitigation as a co-benefit of regenerative ranching: insights from Australia and the United States

Gosnell, Hannah; Charnley, Susan; Stanley, Paige (2020): Climate change mitigation as a co-benefit of regenerative ranching: insights from Australia and the United States. In Interface Focus. 10 (5), p. 20200027. DOI: 10.1098/rsfs.2020.0027.

"In this paper, we explore principles and practices associated with the larger enterprise of ‘regenerative ranching’ (RR), which includes managed grazing but infuses the practice with holistic decision-making. We argue that this broader approach is appealing due to a suite of ecological, economic and social benefits, making climate change mitigation an afterthought, or ‘co-benefit’."
