McKinley, Galen A.; et al. (2020): External Forcing Explains Recent Decadal Variability of the Ocean Carbon Sink

McKinley, Galen A.; Fay, Amanda R.; Eddebbar, Yassir A.; Gloege, Lucas; Lovenduski, Nicole S. (2020): External Forcing Explains Recent Decadal Variability of the Ocean Carbon Sink. In AGU Advances 1 (2). DOI: 10.1029/2019AV000149.

"Here, we use an idealized upper ocean box model to illustrate that two external forcings are sufficient to explain the pattern and magnitude of sink variability since the mid‐1980s."

Yang, Huiyi; et al. (2020): South India projected to be susceptible to high future groundnut failure rates for future climate change and geo-engineered scenarios

Yang, Huiyi; Dobbie, Steven; Ramirez-Villegas, Julian; Chen, Bing; Qiu, Shaojun; Ghosh, Sat; Challinor, Andy (2020): South India projected to be susceptible to high future groundnut failure rates for future climate change and geo-engineered scenarios. In The Science of the Total Environment 747, p. 141240. DOI: 10.1016/j.scitotenv.2020.141240.

"With an increase in global mean temperature predicted for this century accompanied by more frequent extremes, will farming communities need to brace for increased crop failures and hardship? Solar dimming climate geoengineering has been proposed as a possible solution to combat rising global temperature but what effect will it or other climate related adaptation have on crop failures? We performed a crop modelling study using future climate and geoengineering projections to investigate these questions."

Malhotra, Abhishek; Schmidt, Tobias S. (2020): Accelerating Low-Carbon Innovation

Malhotra, Abhishek; Schmidt, Tobias S. (2020): Accelerating Low-Carbon Innovation. In Joule 0 (0). DOI: 10.1016/j.joule.2020.09.004.

"Accelerating innovation in low-carbon technologies is fundamental in order to achieve global climate targets. However, only few technologies are currently on track to meet these targets. Here, we review and synthesize the innovation literature to develop a technology typology that helps explain systematic differences in technologies’ experience rates."

Lemoine, Derek (2020): Incentivizing Negative Emissions Through Carbon Shares

Lemoine, Derek (2020): Incentivizing Negative Emissions Through Carbon Shares. In National Bureau of Economic Research. Available online at https://www.nber.org/papers/w27880.

"I show that commonly proposed emission taxes are not optimal for controlling climate change: they can achieve zero emissions but cannot induce negative emissions. The first-best policy charges firms period by period for leaving a stock of carbon in the atmosphere, not just for injecting carbon into the atmosphere."

Seeley, Jacob Thomas; et al. (2020): Designing a radiative antidote to CO2

Seeley, Jacob Thomas; Lutsko, Nicholas; Keith, David W. (2020): Designing a radiative antidote to CO2. In Geophys. Res. Lett. DOI: 10.1002/essoar.10504359.1. Preprint.

"Previous results indicate that the global hydrological cycle is more sensitive to Solar Radiation Modification (SRM) than is the surface temperature. Thus, it is expected that restoring temperature with SRM would decrease evaporation and precipitation. However, here we show that a more complete radiative antidote to CO2 can be obtained by spectrally tuning the SRM intervention, reducing insolation at some wavelengths more than others."

Frischmann, Chad Jonathan; et al. (2020): Drawdown’s ‘System of Solutions’ Helps to Achieve the SDGs

Frischmann, Chad Jonathan, Mamta Mehra, Ryan Allard, Kevin Bayuk, João Pedro Gouveia, and Miranda R. Gorman (2020): Drawdown’s ‘System of Solutions’ Helps to Achieve the SDGs. Encyclopedia of the UN Sustainable Development Goals. Living reference work entry. https://doi.org/10.1007/978-3-319-71067-9_100-1.

‌"This entry describes the linkages between “Drawdown solutions” and the targets and goals set out by the United Nations Sustainable Development Goals (SDGs). It is proposed that the implementation of these solutions can substantially help to achieve the SDGs by 2030, with even greater gains when implementing actions in parallel as a “system of solutions” enabled by broad-based, effective partnerships at local, regional, and international scales."

Service, Robert F. (2020): The Carbon Vault

Service, Robert F. (2020): The Carbon Vault. Science 369 (6508): 1156–59. https://doi.org/10.1126/science.369.6508.1156.

"Every year, mining and industrial activity generates billions of tons of slurries, gravel, and other wastes that have a high pH. These alkaline wastes, which sit either behind fragile dams or heaped in massive piles, present a threat to people and ecosystems. But alkaline wastes could also help the world avert climate disaster. Reacting these wastes with carbon dioxide (CO2) from the air converts gaseous carbon into minerals and neutralizes the wastes' alkalinity."

Cook-Patton, Susan C.; et al. (2020): Mapping carbon accumulation potential from global natural forest regrowth

Cook-Patton, Susan C.; Leavitt, Sara M.; Gibbs, David; Harris, Nancy L.; Lister, Kristine; Anderson-Teixeira, Kristina J. et al. (2020): Mapping carbon accumulation potential from global natural forest regrowth. In Nature 585 (7826), pp. 545–550. DOI: 10.1038/s41586-020-2686-x.

"Regrowing natural forests is a prominent strategy for capturing additional carbon3, but accurate assessments of its potential are limited by uncertainty and variability in carbon accumulation rates2,3. To assess why and where rates differ, here we compile 13,112 georeferenced measurements of carbon accumulation."
