Summary: Resolving regional carbon budgets is crucial for informing land-based mitigation policy. By collecting inventory estimates of carbon-stock changes and complementing with satellite estimates of biomass changes, a global 'bottom-up' NEE for net land anthropogenic CO2 uptake was obtained, setting an important milestone for global carbon-cycle studies. The study found that global soil heterotrophic respiration amounts to a smaller portion of net primary productivity than previously reported.

Summary: This study assesses the detectability of COVID-like emissions reductions in global atmospheric CO2 concentrations using a simulation model. The unique fingerprint of COVID in the simulated CO2 growth rate is obscured by internal variability and carbon-concentration feedbacks, making it formally detectable only with unrealistically large emissions reductions. COVID-driven changes in CO2 concentrations are overshadowed by internal variability, while carbon-concentration feedbacks further complicate signal detection in the atmosphere.

Summary: Changes in vegetation have significant impacts on water availability. Observations show that global water availability has increased due to vegetation changes, mitigating the recent decline in water availability. However, in water-limited or high-elevation regions, increased vegetation may have adverse effects on water resources.

Summary: This study characterized the spatial-temporal variability and main factors controlling atmospheric CO2 column in the macroregion of Ribeirao Preto, Sao Paulo, Brazil using remote sensing data. Negative correlations were found between Xco(2) and factors such as photosynthesis, relative humidity, and global radiation. Hotspots and coldspots of Xco(2) varied over the years.

Summary: This article conducts GIS spatial analysis on carbon emissions data from major countries and regions, revealing the characteristics of high cumulative emissions in early industrialized countries and low per capita emissions in developing countries. It compares and analyzes the advantages and disadvantages of different emission reduction models and summarizes carbon emission allowances under different scenarios. The article also reviews global carbon allocation methods and the development trends of carbon emissions, providing scientific evidence for future international climate change agreements.

Summary: This study explores the interaction between equity and efficiency in the distribution of global carbon budgets. The results demonstrate that there is potential to improve both equity and efficiency on a global scale, but further improvements will require trade-offs at the national level. Connecting national mitigation actions and potentials can facilitate synergies between equity and efficiency and contribute to the effective achievement of the Paris Agreement's goals.

Summary: Studies show that methane emissions in wetlands are influenced by temperature and are more sensitive to it later in the frost-free season. To improve global methane budget assessments, more detailed measurements of factors influencing methane production are needed.

Summary: Researchers updated the estimation of black carbon emissions using new data, revealing a 32% increase compared to previous estimates, primarily due to field-measured emission factors for residential stoves and differentiated factors for vehicles. Additionally, the updated emissions show an inverse U-shaped trend, driven by factors such as population growth, per capita energy consumption, and vehicle fleet increase.

Summary: This study analyzes global carbon emissions and transfers from aluminum production, consumption, and trade to reveal the carbon distribution across regions and countries. The results indicate an increase in aluminum trade carbon transfer, an increase in carbon emissions from aluminum production, with China being the largest contributor, and the potential for emission reduction in the northern hemisphere as the main consumption region.

Summary: Biogenic volatile organic compounds (BVOCs) have an impact on climate by affecting aerosols, aerosol-cloud interactions (ACI), ozone, and methane. The net climatic impact of BVOCs is uncertain due to their dependence on climate and land use. The description of BVOC chemistry plays a significant role in determining their climatic impact and the pathways by which they influence climate.

Summary: The rapid warming in the Arctic has exacerbated wildfires and thawing permafrost, leading to carbon emissions that are not fully accounted for, impacting global greenhouse gas emission budgets. There is an urgent need for international cooperation to incorporate the latest scientific knowledge on carbon emissions from permafrost thaw and wildfires, and to more aggressively reduce societal emissions to address the global climate crisis.
