Summary: This study assessed the greenhouse gas emissions from rice fields amended with composted two-phase olive mill waste (C-TPOW) in Mediterranean conditions. The results showed that compost reduced CO2 emissions but increased CH4 and N2O emissions. However, there were no significant differences in global warming potential (GWP) and yield-scaled GWP between the compost and control treatments after three years.

Summary: This study developed a framework to obtain multi-level greenhouse gas (GHG) emission factors (EFs) of municipal wastewater treatment plants (MWTPs) in China. The results showed significant differences in GHG EFs among different technologies and provinces, highlighting the importance of detailed technology classification and considering regional disparities. The study also tested the feasibility of the developed EFs and found similar estimation results, suggesting that selecting the appropriate EF based on activity data availability could simplify GHG estimations without sacrificing accuracy.

Summary: Increased nitrogen deposition has a significant impact on soil greenhouse gas emissions. This meta-analysis of 124 simultaneous measurements from 54 studies found that nitrogen addition leads to an increase in the combined global warming potential (CGWP) of CO2, CH4, and N2O. Wetlands are the most sensitive ecosystem to nitrogen addition, and CO2 contributes the most to the CGWP change.

Summary: The article emphasizes the importance of distinguishing between greenhouse gas metrics and ecosystem greenhouse gas fluxes to avoid confusion. It suggests using global warming potential and sustained-flux global warming potential according to their original definitions, while employing CO2-equivalent greenhouse gas fluxes to accurately describe the weighted greenhouse gas exchanges.

Summary: This study found that free-air temperature increase (FATI) does not affect grain yield and CH4 emissions in double rice cropping systems, but stimulates N2O emissions. This could contribute to a positive feedback with future climate warming.

Summary: Composting plays a crucial role in carbon and nitrogen conservation, but losses of carbon and nitrogen still occur during the process. Researchers have explored ways to reduce these losses and enhance conservation through amendments, and proposed potential mechanisms for conservation. Evaluating the contribution of composting requires a comprehensive assessment, and the impact of compost clinker on carbon and nitrogen sequestration capacity needs further investigation.

Summary: This paper analyzes the climate benefits of fast action to reduce methane emissions compared to slower and delayed mitigation timelines. It finds that rapid implementation of available mitigation measures can significantly reduce near-term temperature rise and slow the global-mean rate of warming. Urgently scaling up efforts to implement methane mitigation measures is crucial to limiting climate damages in the near-term.

Summary: This study evaluated the impact of meteorological conditions on greenhouse gas inventories in eutrophic lakes, revealing a significant effect of atmospheric heatwaves on greenhouse gas production, particularly during cyanobacterial blooms in 2012. The research findings suggest a novel interplay between climate change effects on lake hydrodynamics, impacting both bloom characteristics and greenhouse gas production in shallow eutrophic lakes.

Summary: The study examined the effects of Conservation Agriculture (CA) practices of no-till and straw mulch on crop productivity and greenhouse gas emissions in agroecosystems on the Northwestern Loess Plateau of China. Results showed that CA practices significantly improved soil water content, soil organic carbon, soil total nitrogen, and grain yield, while reducing soil temperature. Net CO2 emissions were reduced under CA practices compared to conventional tillage, and CA practices served as sinks of CH4 but did not reduce emissions of N2O, leading to a significant reduction in net Global warming potential (GWP). Soil hydrothermal and nutrient changes controlled crop yield and GHG responses to CA, indicating that adopting sustainable soil moisture improvement practices can enhance crop resilience to climate change and reduce GHG emissions in arid and semi-arid regions.

Summary: This study quantifies the relationship between anthropogenic sulfate aerosols and low-level clouds using satellite observations, and estimates the range of equilibrium climate sensitivity (ECS) by constraining the associated radiative forcing. The results indicate that the uncertainty in aerosol forcing is smaller and ECS may be larger than previously assessed.

Summary: The study reveals that global greenhouse gas emissions are primarily concentrated in the United States, the European Union, and China, while developing countries' aerosol emissions have a more significant negative impact on global radiative forcing. Implementation of measures to improve air quality in developing countries is expected to reduce the negative impact of aerosols but may also exacerbate global warming.

Summary: An integrated catchment management project was established in the late 1990s to study the implications of land use and management change on a typical New Zealand hill country pastoral farm system. Main changes were implemented in 2001-2002, including production forest plantation, indigenous riparian planting, intensification of livestock enterprises, and spaced-tree planting on a 296 ha Mangaotama block.
The study aimed to estimate the greenhouse gas (GHG) balance for the catchment farm by incorporating recent measurement and modeling over a 100-year period (excluding soil carbon). The changes reduced the GHG intensity of the livestock enterprises and turned the system from a net emission source into a long-term net sink, mainly due to planting of Pinus radiata with high carbon assimilation rates. Based on mean tree carbon stocks over 100 years, it was estimated that 36% of the catchment farm would need pine forestry to achieve net zero emissions.

The network has provided valuable knowledge, information, and data not only for ecosystem researchers, but also for other users. This article focuses on eight key lessons in various areas of research and highlights the importance of long-term flux observations.

Summary: Climate warming can reduce global soil carbon stocks by enhancing microbial decomposition. Previous research suggested a negative relationship between carbon quality and temperature sensitivity, implying that recalcitrant carbon is more sensitive to temperature. However, new research indicates that this relationship may be an invalid artifact caused by the arbitrary choice of reference temperature. By using the uncatalysed reaction rate as the carbon quality index, it was found that there is no relationship between carbon quality and temperature sensitivity in enzyme-catalysed reactions. This suggests that the temperature sensitivity of microbial decomposition of soil carbon is similar regardless of its quality, alleviating concerns about the acceleration of warming-induced decomposition of recalcitrant carbon.
