“…All else being equal, better ventilated ocean reduces the carbon sequestration capacity of deep ocean (Skinner et al., 2010) and pump more carbon into the atmosphere as CO 2 (Marinov et al., 2008). Thus, the ocean circulation has been treated as an important regulator for p CO 2 (Li et al., 2023), especially during the glacial period (Sarmiento & Toggweiler, 1984; Siegenthaler & Wenk, 1984). Unfortunately, the CESM1.2.2 experiments done here did not have the ocean biogeochemical module invoked because it was not designed for the Neoproterozoic biogeochemical system and was expensive to run.…”

Ocean ventilation describes the process that water of ocean interior affects and is affected by the atmosphere through exchange within the surface mixed layer (Thiele & Sarmiento, 1990). The rate of ocean ventilation is an important factor in regulating the heat, salinity, and marine elemental cycles in the ocean system. Enhanced ocean ventilation can transport more surface oxidized water into the deep ocean effectively, shaping the oxygen minimum zones, and pump nutrients from the deep into the shallow ocean, affecting life habitats (Yamamoto et al., 2015). Weakened ocean ventilation can reduce atmospheric carbon dioxide level (pCO 2 ) by relocating carbon from the atmosphere to the deep ocean and storing in the deep ocean, which might facilitate glaciation (Anderson et al., 2019;Brovkin et al., 2007;Stephens & Keeling, 2000). Ocean ventilation is affected by climate and continental configuration (Donnadieu et al., 2016). The changes of ocean stratification (Gnanadesikan et al., 2007), strength and location of mid-latitude westerly wind (Russell et al., 2006), and sea-ice cover (Polyakov et al., 2017) associated with climate change all modulate ocean ventilation.Among the factors described above, sea-ice is critically important to ocean ventilation as it directly blocks the sea surface from communicating with the atmosphere. For example, sea-ice expansion during the Last Glacial Maximum (LGM) had a strong isolating effect (Gu et al., 2020), and was probably the dominant contributor to LGM deoxygenation and the enlarged carbon storage in the deep ocean (Cliff et al., 2021;Jaccard et al., 2016).

“…Greenhouse gas (GHG) emissions are considered to be the root cause of environmental problems such as global warming [1], sea level rise, and frequent severe weather [2,3]. It is predicted that global CO 2 emissions may increase the Earth's temperature by 1.5 to 2 • C in the future [4], posing a serious threat to the survival and development of human beings [5]. The Paris Agreement, the first historic global climate change agreement, was signed by 178 countries around the world in 2016 [6], aiming to slow down climate warming and increase the capacity to tackle climate change by limiting global warming to 1.5 degrees Celsius.…”

In addition to creating economic value, crops also serve important ecological functions. Especially their carbon sink function, which plays a key role in mitigating climate change. In this study, the LMDI and the Tapio model were innovatively combined to quantitatively evaluate the carbon emissions and sinks in the Yellow River basin (YRB). It shows that the average annual growth rate of the YRB was −0.1344% during 2002–2020. Carbon emissions show a negative trend due to the transformation and upgrading of agriculture from traditional to modern and the implementation of policies related to China’s agricultural benefits. Agricultural production efficiency is a major factor in inhibiting agricultural carbon emissions, reducing carbon emissions by an average of approximately 8.07 million tons per year. High-carbon emission and high-sink areas in agriculture are mainly concentrated in the southeast of the YRB, where livestock and poultry farming is the principal source of carbon emissions, with rice, wheat, and corn being the principal contributors to the carbon sink. Moreover, there are significant differences in the carbon sink capacity of crops in the YRB. Optimizing crop selection and area distribution can enhance the carbon sink capacity in different regions, contributing to more effective carbon emission control. This study combines agricultural carbon emissions with the carbon sequestration capacity of crops, providing data support and a theoretical basis for the policy formulation and planning of low-carbon agriculture in China. It is of great significance for promoting sustainable agricultural development and mitigating climate change.

“…According to Lin and Zhang (2024), the BP Statistical Review of World Energy 2023 highlights a 0.8% increase in carbon dioxide emissions in 2022 compared to 2021. There is a concerning forecast that global CO 2 emissions could potentially result in a rise in Earth's temperature by 1.5 to 2 degrees Celsius, which poses a severe threat to the survival and development of humanity (Du et al 2023;Li et al 2023). In 2016, a historic global climate change agreement, known as the Paris Agreement, was signed by 178 countries worldwide (Liu and Yang 2021).…”

This paper examines the impact of family ownership and supervisory board characteristics on carbon emission disclosure. It uses balanced panel data and a matched-pair design of 124 non-financial firms listed on the Indonesia Stock Exchange from 2017 to 2019. This study finds that family firms and larger boards improve, while female board members harm carbon emission performance. Further analyses reveal non-linear relationships between family ownership and carbon performance. When control rights are limited, family firms prioritize controlling managers and improving carbon quality. Conversely, they prioritize personal objectives over environmental concerns when there are high control rights, resulting in decreased carbon emission performance. Additionally, family board members generate more carbon information, indicating the family owners effectively utilize their position on the supervisory boards to influence the company’s carbon emission performance. Finally, the study reports that more faculty member boards seem to hurt carbon emission reduction efforts. This result suggests that the diversity of their professional experiences does not affect the environmental effectiveness of supervisory boards. Our findings highlight the importance of understanding SEW principles and their connection to families in comprehending Indonesian corporate carbon emissions disclosures. The findings of this study enrich the worldwide literature by exploring the potential benefits of family business environmental performance. This study also adds to the literature on corporate governance, especially the role played by supervisory boards. Our findings align with the resource dependence theory, emphasizing the central function of supervisory boards as a monitoring tool. This study is constrained by its reliance on carbon emission data extracted from the annual reports of public firms, with a particular emphasis on pre-COVID-19 data. Future research should focus on sustainability reports and explore the time frame encompassing COVID-19 (2020–2022 datasets) to determine any differences in the findings.
