Sorghum is a vital food and feed crop in the world’s dry regions. Developing sorghum cultivars with high biomass production and carbon sequestration can contribute to soil health and crop productivity. The objective of this study was to assess agronomic performance, biomass production and carbon accumulation in selected sorghum genotypes for production and breeding.

Forest carbon sequestration capacity in China remains uncertain due to underrepresented tree demographic dynamics and overlooked of harvest impacts. In this study, the authors employ a process-based biogeochemical model to make projections by using national forest inventories, covering approximately 415,000 permanent plots, revealing an expansion in biomass carbon stock by 13.6 ± 1.5 Pg C from 2020 to 2100, with additional sink through augmentation of wood product pool (0.6-2.0 Pg C) and spatiotemporal optimization of forest management (2.3 ± 0.03 Pg C).

Here, the authors investigated the rationale and urgency behind the implementation of Nature-based Solutions on sequestering carbon using literature review and meta-analysis. They also project the changes in terrestrial carbon sink of Tibetan Plateau grassland ecosystems using model simulations with different future emissions scenario.

Urban forest is considered nature-based solution for mitigating the adverse impacts of climate change. However, large-scale quantification of urban forest synergistic effect is still limited. This study integrated multi-source remote sensing data, machine learning, and geospatial methods to quantify the synergistic effect (i.e., spatial interaction) of urban forest on urban heat island, PM_2.5 concentration, and carbon stock and its driving mechanism in China.

Current work is focused on exploring carbon dioxide uptake by different methods of green biotechnology and how environmental pollution affects that uptake. The study examined how the relationship between environmental pollution and carbon sequestration can be optimized by the technique of green biotechnology which affects the overall plant health. For this purpose, leaves from twenty-six plant species including Michelia, Anona Squamosa, Catharantha roseus, Elaeis Guineenis, Hibiscus rosa sinensis, and Epipremnun pinnatum were taken and divided into two sets. One set was washed with water and the other one was left with dirt on it to demonstrate the effect of pollution on carbon sequestration.

In this paper, the authors seek to historicise the practices, discourses and actors that have constructed the ocean as a climate change solution space. They conceptualise the debate about the mitigation potential of the ocean as a contested site of governance, where varying actors form alliances and different sociotechnical narratives about climate action play out.

Carbon mineralization is the most secure form of carbon sequestration, but the value of mineral trapping relative to those of other mechanisms has not been quantified. Here, a techno-economic framework is developed to determine a levelized (investment) value of mineralization across a range of scenarios for CO₂ capture or removal, injection schemes, and mineralization rates.

U.S. forests, particularly in the eastern states, provide an important offset to greenhouse gas (GHG) emissions. Some have proposed that forest-based natural climate solutions can be strengthened via a number of strategies, including increases in the production of forest biomass energy. The authors used output from a forest dynamics model (SORTIE-ND) in combination with a GHG accounting tool (ForGATE) to estimate the carbon consequences of current and intensified timber harvest regimes in the Northeastern United States. They considered a range of carbon pools including forest ecosystem pools, forest product pools, and waste pools, along with different scenarios of feedstock production for biomass energy.
