Summary: Global food systems face the challenge of providing healthy and adequate nutrition through sustainable means. Recent advances in novel food production technologies demonstrate potential solutions for improving the sustainability of food systems. Replacing animal-source foods with novel or plant-based foods can significantly reduce environmental impacts and meet nutrition and consumption constraints.

Summary: The global warming potential of geopolymers compared to OPC is highly dependent on the system boundary for analysis, allocation scenario, material transportation distances and mode, with results showing that geopolymers can either have significantly lower or significantly higher CO2-eq emissions than OPC depending on these factors.

Summary: The study shows that as global warming intensifies, the number of landfalling atmospheric rivers (ARs) and the amount of water they transport will increase. The proportion of beneficial ARs will decrease, while the proportion of hazardous ARs will increase. This shift will result in a gradual increase in flood damages, highlighting the importance of climate mitigation efforts.

Summary: This study assesses the potential of increasing soybean yields in Brazil without further deforestation in the Amazon forest, which could reduce CO2 emissions. Accelerating yield improvement and expanding soybean cultivation only in areas currently used for livestock production could significantly reduce deforestation and global climate warming.

Summary: Recent research on integrated crop-livestock systems in semiarid regions found that grazed cropland had significantly higher net global warming potential compared to ungrazed cropland, mainly due to emissions from enteric fermentation. Ungrazed cropland had lower CO2 emissions from seed production and field operations, while grazed cropland showed greater soil CH4 uptake. Both systems had net greenhouse gas emissions to the atmosphere, suggesting the need for novel practices to mitigate these emissions in semiarid conditions.

Summary: This study reveals that the intensity of night-time fires has increased due to hotter and drier nights. The global daily minimum vapour pressure deficit (VPD) has increased by 25% from 1979 to 2020. The annual number of flammable night-time hours on burnable lands has increased by 110 hours, allowing for five additional nights of continuous flammability. Across nearly one-fifth of burnable lands, flammable nights have increased by at least one week. Night fires globally have become 7.2% more intense from 2003 to 2020, as measured by satellite records. These findings highlight the lack of relief during the night for wildfire suppression teams. It is expected that continued night-time warming, driven by anthropogenic climate change, will lead to more intense, longer-lasting, and larger fires.

Summary: In a 42-day microcosm experiment, we found that nanoplastics have significant effects on soil microbial community structure, nitrogen removal processes, greenhouse gas emissions, and ecosystem multifunctionality. Positively charged nanoplastics have a stronger impact on soil microbial community structure and functions. Nanoplastics at environmentally realistic concentration inhibit soil denitrification but enhance anammox. Nanoplastics decrease soil N2O flux, while increasing CO2 and CH4 emissions. Nanoplastics can increase ecosystem multifunctionality but also increase greenhouse gas emissions.

Summary: The study shows that protecting 20% of the world's mangrove forests through carbon financing can be financially sustainable, with 1.1-1.3 million hectares potentially achieving this over a 30-year period. This initiative could reduce up to 29.8 million tons of CO2 emissions annually and generate a return on investment of nearly $3.7 billion per year.

Summary: The emissions of HFCs have significantly increased in the past two decades due to the phaseout of ozone-depleting substances. However, the implementation of regulations to limit HFC use in several countries has led to lower emissions than previously projected. The Kigali Amendment is expected to further reduce emissions and mitigate the contribution of HFCs to global surface warming.

Summary: This study introduces a new dynamic GWP method to analyze the sustainability of cementitious composites, taking into account the changes over time. Results show that nano-modified A concretes have the lowest GWP at year 100, while CO2-cured concretes exhibit the lowest GWP at year 0. Overestimation of the GWP for nano-modified and CO2-cured concretes may occur if the effects over time are not considered.

Summary: This study developed an online scheme to simulate tropospheric (OO)-O-18-O-18 abundances within the GEOS-Chem chemical transport model in order to investigate uncertainties in previous offline box-model frameworks. By incorporating pressure dependence and efficient titration effects into the calculation scheme, the model results showed quantitative agreement with all available observations, indicating that tropospheric ozone burden increased less than 40% over the twentieth century.

Summary: This study investigates the feasibility of using airborne in situ measurements to derive transit time distributions over the highly convective tropical western Pacific. The study demonstrates the method's effectiveness through measurements from the CONTRAST experiment. By quantifying uncertainties associated with chemical lifetimes and characterizing the source region contributing to transport, the study supports the hypothesis that there is enough information in measurements to resolve dynamical variability in the region.

Summary: Rapid transport by deep convection is an important mechanism for delivering surface emissions of reactive halocarbons and other trace species to the tropical tropopause layer. This study found short-lived halocarbons and other trace gases in the TTL over the western Pacific Ocean that originated from Asia. The measurements indicate an increase in chlorinated organic species and non-methane hydrocarbons, as well as a chemical composition impacted by biofuel/biomass burning and industrial emissions.

Summary: We analyzed global airborne observations to estimate emissions from oil and gas operations. By updating the emissions configuration in a chemical transport model, we were able to simulate the global distribution of propane and ethane and compare it with observed data. We found that emissions in oil-producing basins are dominated by pre-processing activities.

Summary: This study investigates the global seasonal distribution of CH2Br2 and CHBr3 and finds that CH2Br2 shows pronounced seasonality in both hemispheres, while CHBr3 exhibits larger variability and less clear seasonality. The observations and model simulations show good agreement in the lowermost stratosphere, but there is a discrepancy in the southern hemispheric autumn. More extensive observations in the southern hemisphere are needed to fully understand the impact of these substances on lowermost-stratospheric ozone loss.

Summary: Our understanding of the biogeochemical cycling of dimethyl sulfide (DMS) in the Peruvian upwelling system is still limited. We conducted oceanic and atmospheric measurements of DMS in this region during two shipborne cruises in December 2012 and October 2015. DMS concentrations in surface waters were influenced by nutrient availability, and no elevated concentrations were found in the oxygen minimum zone off Peru. DMS, DMSP, and DMSO may act as radical scavengers, supported by their negative correlations with NVP ratios. Atmospheric DMS concentrations varied significantly but were primarily driven by seawater DMS. The Peruvian upwelling region was identified as a source of atmospheric DMS, but emissions were moderate compared to adjacent regions.
