Summary: Climate change poses risks to natural and human systems, prompting the need for solutions such as green infrastructure (GI). While the climate benefits of GI have been studied extensively, the connections between these benefits, co-benefits, and trade-offs remain unclear. This study systematically reviews evidence from 141 papers to provide a comprehensive overview of these linkages, categorizing GI types along a green-grey continuum for easy access by researchers and practitioners. Furthermore, the analysis includes recommendations for maximizing benefits and minimizing trade-offs to promote climate-resilient pathways through GI.

Summary: This study integrated three trade-off types for ecosystem services (ES) and established an analytical framework, which was then applied to the Fenghe River watershed in China. The results showed obvious trade-offs between food provision and water yield, carbon sequestration, and soil retention; weak conflicts between environmental experts and other stakeholders; and trade-offs between soil retention and food provision, water yield, carbon sequestration, and eco-recreation. Based on the supply-demand match perspective, deficits were found for food provision, water yield, and carbon sequestration in the northern urban areas, while surpluses existed in the southern areas. The Fenghe River watershed was divided into 10 land use management zones based on the spatial characteristics of these trade-offs.

Summary: The Latin America and the Caribbean (LAC) region is important for global agriculture and carbon sinks. This study evaluates the impacts of agricultural market integration and land-based climate mitigation policy on LAC's economies, agricultural production, trade revenues, and land-water-climate systems. Increased market integration leads to higher agricultural production and trade revenues, while climate mitigation measures increase revenues through higher agricultural prices. The combined outcomes highlight the need for understanding interactions between multiple drivers and careful planning to address trade-offs.

Summary: While there is limited knowledge about the impact of elevated atmospheric CO2 concentrations (eCO2) on mangrove carbon cycling, studies show that eCO2 can enhance carbon storage in mangroves by altering plant productivity, species composition, carbon fluxes, and deposition. This creates a negative feedback to climate change by increasing mangrove's ability to sequester additional carbon and reducing CO2 build-up. Additionally, eCO2 affects warming and sea-level rise in ways that influence mangrove response in both antagonistic (i.e. carbon loss to decomposition) and synergistic (i.e. soil carbon burial) manners. Long-term field observations and in situ simulation experiments are necessary for understanding the mechanisms and predicting future changes in mangrove carbon sequestration.

Summary: We studied the spatiotemporal variability of near-surface CO2 concentrations in Mongolia from 2010 to 2019 across four climate zones. By validating satellite data with ground-based observations, we found that CO2 concentrations in Mongolia steadily increased, with the highest levels in the southeastern desert and the most significant growth in the northwestern steppe. Monthly and seasonal variations were observed in each climate zone, with CO2 levels decreasing in summer and reaching a peak in spring. We also found a negative correlation between CO2 concentrations and vegetation parameters during summer, indicating the potential for carbon sequestration.

Summary: Societal demands for food security and environmental sustainability have prompted the study of synergies and trade-offs between soil functions across Europe. The research found that managing and monitoring soil multifunctionality is feasible, but there are constraints and trade-offs between soil functions. Nutrient cycling, biodiversity, and climate regulation are less frequently delivered at high capacity compared to primary productivity and water regulation. Synergies and trade-offs between soil functions vary by climatic zone and land-use type.

Summary: This study found that the increase in summer precipitation in southeastern South America is influenced by the South American low-level jet. The increased moisture flux through the jet explains a portion of the observed precipitation trend, and the increased humidity is identified as the fundamental driver for the increased moisture flux and precipitation. Additionally, the intensification of the jet's velocity also contributes to the enhanced precipitation.

Summary: Earth's ecosystems are facing increasing threats from hot drought, which can have significant impacts on the carbon cycle. Through a natural experiment, it was found that hot drought leads to a significant reduction in gross primary production (GPP), with both meteorological and hydrological factors playing a role. Future increases in air temperature and vapor pressure deficit may lead to more frequent and intense hot droughts, exacerbating the reduction in GPP caused by drought.

Summary: The study investigates the climate patterns that precede anomalous summer burned forest area in California. It finds that factors such as high vapor pressure deficit, high temperatures, low precipitation, and low soil moisture are significantly correlated with July burned area. The study also reveals that extreme July heat contributes to the extent of fires, but historical correlations are not significant. The findings provide important insight into predicting the severity of upcoming summer wildfire seasons.

Summary: Increasing atmospheric CO2 and global warming will alter the global hydrological cycle, threatening freshwater availability. However, models have different projections for tropical hydrological changes, mainly due to differences in vegetation cover, stomatal conductance responses, atmospheric moisture, and circulation. Atmospheric responses to sea surface warming also contribute to divergence in hydrological projections.

Summary: This study utilizes temporal convolutional neural networks to generate a consistent land-cover and land-use change dataset for the Indo-Malaysian region over a period of nearly 35 years. The results reveal a decrease in forests in Southeast Asia and an increase in South China and South Asia. Cropland expansion is identified as a major driving force behind deforestation in mainland Southeast Asia, while the increasing forest cover in South China is primarily attributed to savanna conversion. These findings provide valuable insights for studies on land-use theory, environmental and climate changes, and regional land-use policy evaluations.

Summary: This study investigates the response of early summer droughts over the Central Plains to a moderate warming scenario using tree-ring based reconstructions and six model ensembles. The findings indicate that even in the absence of robust precipitation declines, there is a potential increase in the severity and risk of early summer droughts over the Central Plains due to moderate warming. Additionally, the impact of major atmospheric ridging events on drought severity is projected to become stronger.

Summary: We use the Community Atmosphere Model version 5 Green's function q-flux perturbation experiments to investigate the impact of remote forcing on U.S.-wide summer heat extremes. Our findings reveal that positive q-flux forcing over the western North Pacific Ocean is the most effective in increasing the frequency of heat extremes. This is achieved through elevated sea surface temperature and precipitation over the western North Pacific, generating an eastward propagating Rossby wave train and an anomalous ridge over the contiguous U.S. Negative q-flux forcing over the eastern tropical Pacific also leads to increased heat extreme frequency but with less effectiveness.

Summary: Recent research shows that climate models incorrectly simulate the equatorial Pacific response to greenhouse gas warming, leading to a discrepancy between model predictions and observations of a more La Nina-like state. This could result in incorrect projections of regional tropical cyclone activity and other perils such as severe convective storms and droughts. While these errors may be transient, the transient response is important for climate adaptation in the next several decades. Therefore, it is desirable to develop projections that represent a broader range of possible future tropical Pacific warming scenarios, even if current coupled earth system models cannot produce such projections.

Summary: This study evaluates a range of trends in climate models and finds that they fail to accurately reproduce the surface temperature trends and observed decadal-scale swings in the equatorial and subtropical east Pacific Ocean. Models with high climate sensitivity are less likely to reproduce the observed swings, potentially due to an incorrect balance of cloud feedbacks. These findings highlight the need to increase understanding of decadal-scale variability.
