Summary: The study developed an improved parameterization for wind-driven lake spray aerosol (LSA) emissions and studied the impact of these emissions on regional chemistry in the Great Lakes region. It was found that LSA particles emitted from the surface of the lakes significantly affect particulate NO3- and NH4+, as well as gas-phase species in the region.

Summary: The study found that over the past few decades, lake water quality in terms of total phosphorus and chlorophyll a has significantly decreased, while dissolved organic carbon has increased. Climate, lake morphology, and the presence of invasive dreissenid mussels have a certain impact on changes in water quality.

Summary: Climate warming is impacting the Laurentian Great Lakes and their watershed by increasing winter air temperatures, decreasing ice cover extent, and changing precipitation patterns. This review highlights the importance of winter studies on the physics, chemistry, and biology of the lakes, emphasizing the significant effects of winter conditions on the Great Lakes ecosystem. Understanding the properties and formation of Great Lakes ice, along with winter measurements of key parameters, are crucial for bridging the winter knowledge gap and improving predictions of future impacts.

Summary: This study investigated the spatial and temporal variations of vegetation phenology in the dryland ecosystems of the Great Lakes Region of Central Asia (GLRCA). The results showed that the start of growing season (SGS) and the end of growing season (EGS) were significantly earlier regionally, leading to a shorter length of growing season (LGS) across the GLRCA. Surface temperature was found to be a major determinant of advanced spring phenology, while increased soil moisture and mitigated drought would delay spring phenology. The response of autumn phenology to surface temperature and short-wave radiation varied across different climate zones.

Summary: This study estimated the shortwave radiative effects of absorbing aerosols over the Indian landmass using a combination of spaceborne and ground-based observations, finding that pre-monsoon aerosol loading is mainly influenced by mineral dust and high aerosol warming within the planetary boundary layer is mainly caused by carbonaceous aerosols.

Summary: Comparing the downscaled simulations from different methods, it is found that the HD statistical downscaling approach performs reasonably well in reproducing extreme precipitation and maximum temperature, while raw historical WRF simulations show significant bias in extremes. The projected changes in future summer extreme precipitation differ between downscaling methods, with the WRF simulations showing substantial increases and the HD approach exhibiting moderate decreases overall. The WRF simulations at 4 km also suggest a decoupling effect between seasonal totals and extreme daily precipitation for summer, indicating the possibility of more intense summer extremes at different time scales in the late twenty-first century.

Summary: The concentrations of HCB and OCS in the atmosphere have remained relatively stable over the past few decades, indicating that emissions from industrial processes are widespread and ongoing. The northern hemisphere appears to be the primary source of these chemicals, with higher concentrations observed compared to the southern hemisphere. Unlike other legacy chemicals, global restrictions on the use of HCB and OCS have not been as effective.

Summary: This study quantified the contributions of moisture source regions to precipitation in the Great Lakes Region (GLR) and identified the primary sources of moisture as the Great Plains (GPs) and the GLR itself. The findings showed a shift in the peak timing of moisture contribution from the GLR and GPs, explaining the double peaks in GLR precipitation in June and September. Furthermore, it was observed that moisture from the GPs contributed more to heavy precipitation, while moisture from the GLR contributed more to light precipitation. Additionally, there was a statistically significant increasing trend in moisture contribution from the mid-Pacific, attributed to changes in atmospheric circulation.

Summary: This study identifies and analyzes DWAA events based on the SPEI index in GLRCA, revealing an increasing frequency of such events globally. GLRCA shows an overall wetting trend but with heavy drought in the southwest. While both D-W alternation events and W-D alternation events exhibit slight decreases at the regional scale, they demonstrate contrasting trends in different periods. Spatially, there is significant heterogeneity in the variation of these events, with a significant increase observed in the southwest of the arid climate zone.

Summary: The unimpeded transfer and spread of invasive species in freshwater systems is a global concern that alters species compositions, disrupts ecosystem processes, and diverts economic resources. By tracing the fishing behavior of anglers, a study found that there is a high cumulative probability of invasive species transport by several million people fishing each year throughout the extensive freshwater network of the Great Lakes. Understanding and managing this transfer of invasive species can be aided by comprehensive georeferenced surveys and spatial analysis of fishing destinations.

Summary: This study conducted a model intercomparison to compare different model setups in simulating outputs in the Great Lakes region. The results showed that the machine-learning-based model performed the best in simulating streamflow, while the locally calibrated models and regionally calibrated models showed varying performances in different areas. The study also compared additional model outputs, such as evapotranspiration, soil moisture, and snow water equivalent, against gridded reference datasets.

Summary: Xenobiotic chemical emissions from the informal electronic waste recycling sector pose an emerging problem for developing countries, with scale and impacts yet to be evaluated. A study in four megacities in India found that electronic waste activities significantly contributed to atmospheric organic pollutants, particularly dioxin-like PCBs.

Summary: Local governments participate in collaborative governance primarily to leverage external funding opportunities, with the advantage of multijurisdictional collaboration to reduce flooding and improve water quality being important but secondary. While legal authorities were used in two cases to form agreements to address flooding, collaboratives largely avoided water quality issues in all four cases due to political tensions.
