Summary: This study uses spatial econometric techniques and the Spatial Durbin Model (SDM) to test the presence of beta-convergence in global Environmental Performance (EP). The findings indicate positive spatial autocorrelation in EP, suggesting that countries with similar EP are clustered together. The study also reveals that physical capital degrades the environment while break-even investment (BEI) improves it.

Summary: This study found that promoting environment-related tax increases green exports among high-income countries. Additionally, the increase in a country's green trade depends on the energy intensity level of its trading partner countries. Low- and middle-income countries need to promote environmental policies and green production processes to enhance competitiveness in the global market.

Summary: This study evaluates the potential environmental impacts of increasing reactive chlorine emissions as a climate mitigation strategy to reduce methane levels. The results show that significant changes occur in other important climate forcers, such as tropospheric ozone. The quantity and method of adding chlorine, as well as its interactions with climate pathways, must be carefully considered.

Summary: Fire has a significant impact on global vegetation structure and composition. A statistical analysis of remotely sensed burnt area, fire size, and fire intensity was conducted. The results showed that burnt area is mainly influenced by fuel availability and dryness, fire size is influenced by conditions promoting fire spread, and fire intensity is influenced by fractional tree cover and road density. Landscape fragmentation constrains burnt area and fire size, while fuel moisture constrains fire intensity.

Summary: The concept of planetary boundaries assesses the stability of the Earth system, with studies suggesting a non-linear relationship between economy and environmental degradation. While an inverted-U association was found for climate change and ocean acidification, other factors such as biochemical cycles and biodiversity loss did not support the environmental Kuznets curve hypothesis. This provides a new perspective for policymakers and investors to consider for sustainable development globally.

Summary: China's rare earth exports have significant environmental costs, with foreign consumers responsible for over half of these costs. East Asian countries, particularly Japan and South Korea, make the largest contribution to these costs. The environmental impact is mainly caused by rare earth raw materials and high value-added products. Recommendations include rational pricing and production-and consumption-based measures to mitigate environmental impacts.

Summary: The study aims to achieve the dual effects of technological progress and energy conservation and emission reduction in developing countries' participation in global value chains through research on GVC, technological progress, and environmental pollution. The research findings suggest the existence of a value chain threshold in developing countries, where technological progress may lead to an increase in pollution below the threshold but can reduce emissions above it. These results provide a theoretical basis and practical suggestions for developing countries to realize green development while participating in globalized value chains.

Summary: Through analyzing the rewiring of genetic networks in yeast under different environmental conditions, new differential interactions were discovered, highlighting functional connections between different gene pairs. However, the majority of genetic interactions remained stable across different conditions, suggesting that the global yeast genetic interaction network is robust to environmental perturbations and reflects the fundamental functional architecture of a eukaryotic cell.

Summary: The global finance and business sector, with a trillion-dollar value, has a significant impact on economic production and services through trade systems. However, the environmental impact caused by this sector's final demand is often overlooked. Using a global multi-regional input-output model, this paper estimates the carbon dioxide (CO2), sulfur dioxide (SO2), and particular matter PM10 footprints of the finance and business sector in 187 economies from 2000 to 2016. The results highlight the peak of global environmental footprints a decade ago, with current figures of approximately 1371 million tons of CO2, 8.2 million tons of SO2, and 6.1 million tons of PM10. Furthermore, the study identifies the critical economy-sectors responsible for 99% of the environmental footprints and proposes policy interventions to mitigate these footprints through environmental intensity, production efficiency, and trade network improvements.

Summary: This paper introduces the new Navy Earth System Prediction Capability developed by NRL, which provides operational forecasting for timescales ranging from days to subseasonal. The system includes both a low-resolution ensemble system and a high-resolution deterministic system, with an eddy-resolving global ocean model. Based on analyses and forecasts from January 2017 to January 2018, the Navy-ESPC ensemble forecasts exhibit skill comparable to other numerical weather prediction centers for large-scale atmospheric phenomena, and perform better than climatology for ocean surface temperatures in the tropics and midlatitudes, as well as for Pan-Arctic and Pan-Antarctic sea ice extent predictions.

Summary: Gravity waves are key drivers of atmospheric circulation, and studying their sources and propagation characteristics is crucial for improving climate models. By tracing GWs over the Southern Ocean, it was found that wave sources mainly come from small, mountainous islands and the Andes mountain range, with evidence of southward propagation and large horizontal distances traveled by the waves. This suggests that atmospheric models need to better incorporate the possibility of large horizontal propagation of gravity waves.

Summary: This study presents an accurate precipitation climatology for tropical depression (TD), tropical storm (TS), and tropical cyclone (TC) occurrences over oceans using high-quality precipitation datasets and TC center positions. The study analyzes the impacts of TC movement direction and wind shear on the spatial distribution of TC precipitation, as well as the eyewall contraction process during TC intensification. The research confirms previously published results on TC precipitation distributions in relation to wind shear direction and provides detailed distributions for each TC category and TS.

Summary: Recent studies have found a connection between anomalously warm winter temperatures in the stratosphere and high-latitude summer mesopause temperatures. It has been suggested that the 2-day wave and inertial instability play important roles in warming the high-latitude summer mesopause. Understanding the relationship between these phenomena can help explain the changes in temperatures in the summer mesopause region.

Summary: The paper presents an approximate solution method based on a single upgoing gravity-wave mode for each Fourier component, which is computationally cheaper and simpler. This approach is shown to be mathematically equivalent to the exact solution method using all wave modes for the dispersion-relation PDE. The accuracy of the single-mode approximation is demonstrated through comparison with realistic examples, showing reasonably accurate results.

Summary: This study analyzes and compares stratospheric gravity waves observed during a research flight over the Southern Ocean with numerical weather prediction (NWP) model results. The agreement between the model output and observations is remarkable, and the high-resolution NWP models are capable of reproducing the observed upper-stratospheric gravity waves. The combination of unique airborne observations and high-resolution NWP output provides evidence that parts of the stratospheric gravity wave belt over the Southern Ocean might be generated by eastward-propagating Rossby wave trains along the midlatitude waveguide.

Summary: This study examines the impact of the additive inflation technique on biases and forecast errors of integrated vapor transport (IVT). The results show that the technique can significantly reduce IVT biases, especially in tropical regions. However, in some areas, the technique may increase IVT biases, which may be related to the change in sign and structure of the control IVT biases.

Summary: Gravity wave momentum and energy deposition play a significant role in the momentum and heat budgets of the stratosphere and mesosphere, impacting predictability across scales. GW parameter retrievals using GWPR in conjunction with a data assimilation system help optimize parameters and improve mesospheric forecasts. The method reduces analysis increments and reveals seasonal variations in wave spectrum characteristics, especially in the winter extratropics.

Summary: Recent advances in data processing from the NASA Aeronomy of Ice in the Mesosphere satellite's Cloud Imaging and Particle Size (CIPS) instrument allow the observation of bright mesospheric clouds at mid-latitudes. The frequency of these clouds in the northern hemisphere shows no trend from 2007 to 2021 and no dependence on the solar cycle, but extreme interannual variability. This study investigates the possible link between these clouds and the propellant exhaust from orbital vehicles launched at lower latitudes. The analysis suggests that space traffic has a strong influence on the interannual variability of these bright mesospheric clouds.

Summary: The most common boundary condition imposed at the model top in height-based models is a rigid lid complemented by an absorbing sponge layer, which is unphysical and inappropriate for large-scale heating and cooling processes in the upper atmosphere. To address this problem, a physics-based open atmosphere boundary condition is derived from first principles, which allows fluid to smoothly exit and enter the model domain during heating and cooling processes. This boundary condition is stable and does not produce spurious oscillations near the model top unlike the rigid boundary condition, and does not require any tuning parameters unlike sponge layers.

Summary: The virtual temperature model used for moisture-modified tropospheric dynamics is extended to include a new component for the thermosphere. The resulting hybrid virtual potential temperature smoothly transitions between different atmospheric layers. Upgrading to this new model allows numerical weather prediction (NWP) models to capture dynamic aspects of the thermosphere while preserving the accuracy of tropospheric predictions.

Summary: Current operational models have limited forecast skill for ocean mesoscales, but new research shows that considering uncertainties in initial conditions can significantly extend the forecast range and improve accuracy. Ensemble simulations can filter out unconstrained scales, thereby increasing the predictability of ocean mesoscales.
