Summary: This study examined the variations of CO2 and CH4 partial pressures in eight nested streams and rivers over four years, revealing the impact of concentrations and gas transfer velocities on CO2 and CH4 fluxes. The findings suggest that CO2 fluxes increase with discharge, while CH4 fluxes are modulated by the dynamics of gas transfer velocity and concentration.

Summary: This study reveals that damming of rivers alters the spatial distribution of carbon in sediments, leading to higher CH4 and CO2 concentrations upstream compared to downstream. During reservoir impounding periods, CH4 diffusive flux is higher upstream than downstream, while CH4 emissions are predominantly by ebullition, with significantly higher flux downstream during discharging periods. The increase in TOC in downstream sediment is attributed to riparian zone soil erosion caused by water level fluctuations.

Summary: The biosynthesis of PHAs from C1 gases offers a promising solution to climate change and microplastic pollution, as it can reduce production costs and environmental impact associated with petroleum-based plastics. Autotrophs, acetogens, and methanotrophs are strains capable of producing PHA from CO2, CO, and CH4, demonstrating the potential for using costless C1 gases as sustainable carbon sources for bioplastic production.

Summary: Livestock grazing and soil freeze-thaw cycles both have significant impacts on the soil-atmosphere exchange of greenhouse gases in grasslands, with grazing reducing GHG emissions and FTCs stimulating them. The interaction between grazing and FTCs affects CO2 and CH4 fluxes significantly but not N2O fluxes.

Summary: The study demonstrates the significant influence of nickel loading on the performance of CO2 reforming of methane catalysts. Lower nickel loading can lead to increased CH4 conversion stability without coke formation, while higher nickel loading results in decreased activity and carbon accumulation.

Summary: In this study, a technique for natural gas analysis based on polarized Raman spectroscopy is presented. By using only the isotropic components of spectra, the procedure for extracting concentrations is simplified and the measurement accuracy is improved for components with spectral overlap. This technique is of great importance in the analysis of multicomponent gas mixtures and the measurement of isotopic composition.

Summary: The current understanding of how the cropland nitrogen cycle responds to elevated atmospheric CO2 is limited. This study demonstrates that elevated CO2 alone promotes the intensification of nitrogen and carbon cycles in global croplands. This has significant implications for crop nitrogen harvest, fertilizer input requirements, and reactive nitrogen loss under future eCO2 scenarios. Incorporating the effect of rising CO2 on the nitrogen cycle into Earth system models is crucial for providing robust scientific evidence for policymaking.

Summary: This study utilizes satellite observations to quantify emissions from a gas well blowout, presenting a method to provide multiple estimates of emissions during the event. The integration of information from multiple satellites allows for better assessment of variability and quantification of total methane released. Multisatellite observations can aid in determining the pervasiveness of oil/gas well blowouts globally, facilitating corrective action and assessing their impact on methane budgets.

Summary: In this study, a miniaturized differential photoacoustic cell is designed for the detection of CH4 and CO2. A new dual differential method is proposed to enhance the photoacoustic signal. The sensitivity of the detection is further improved by employing distributed feedback lasers and wavelength modulation spectroscopy.

Summary: Climate warming can impact freeze-thaw cycle patterns in northern high-latitude regions and affect permafrost carbon emissions. This study examines the relationships between carbon emissions, bacterial community, and soil variables in a permafrost-affected forest-wetland ecotone in Northeast China. The results show that freeze-thaw cycles significantly regulate CO2 and CH4 emissions by reducing bacterial community diversity and increasing the concentration of available soil substrates.

Summary: The amount of CO2 emitted into the atmosphere from rivers is estimated to be four times higher than the total carbon flux to the oceans, with nocturnal emissions being 27% higher on average. This nocturnal increase is primarily attributed to daytime photosynthesis fixing CO2. Current estimates are significantly underestimated due to reliance on daytime measurements, and not accounting for the difference in emissions between day and night can lead to a further underestimation.
