ABSTRACT Plants have co‐evolved with a wide range of microbial communities over hundreds millions years, this has drastically influenced their adaptation to biotic and abiotic stress. The rapid development multi‐omics approaches greatly improved our understanding the diversity, composition, functions plant microbiomes, but how global climate change affects assembly microbiomes roles in regulating host changing environmental conditions is not fully known. In review, we summarize recent advancements community responses factors such as elevated CO 2 levels, warming, drought. We further delineate research trends hotspots plant–microbiome interactions context change, key mechanisms by which influence climate. propose that future urgently needed unravel impact genes signal molecules modulated on communities, elucidate evolutionary response plant–microbe at level, engineer synthetic mitigate effects fitness.

Abstract In the context of climate warming, runoff changes in Tianshan Mountains vary widely across basins, with both increasing and decreasing trends. However, underlying mechanisms remain to be elucidated due complexity response components (rainfall runoff, snowmelt glacier runoff) change.

A multivariate calibration scheme was used constrain hydrologic model generate reasonable component partitioning. Our results indicate that responses are highly correlated extent at basin scale.

Anthropogenically forced climate change signals are emerging from the noise of internal variability in observations, and impacts on society growing. For decades, Climate or Earth System Models have been predicting how these will unfold. While challenges remain, given growing trends lengthening observational record, science community is now a position to confront signals, as represented by historical trends, models with observations. This review covers state ability represent system. It also outlines robust procedures that should be used when comparing modeled observed move beyond quantification into understanding. Finally, this discusses cutting-edge methods for identifying sources discrepancies importance future confrontations.

Abstract Extreme weather events severely impact human and natural systems, their impacts would be exacerbated when occur synchronously. Extensive studies have examined changes in individual under global warming, but the synchrony of multiple remain less understood. Here we quantify extreme heat precipitation over land areas assess how it responds to climate change. We show regional disparities with stronger lower latitudes weaker middle latitudes.

Constraining uncertainty in projected precipitation over land with causal discovery

Earth System Dynamics, Journal Year: 2025, Volume and Issue: 16(2), P. 607 - 630

Published: April 24, 2025

Abstract. Accurately projecting future precipitation patterns over land is crucial for understanding climate change and developing effective mitigation adaptation strategies. However, projections of changes in state-of-the-art models still exhibit considerable uncertainty, particular vulnerable populated areas. This study aims to address this challenge by introducing a novel methodology constraining model with causal discovery. Our approach involves multistep procedure that integrates dimension reduction, network estimation, evaluation, weighting scheme which based on the historical performance (the distance reanalysis dataset) interdependence Coupled Model Intercomparison Project Phase 6 (CMIP6) other models). To uncover significant pathways dynamical interactions datasets, we estimate time-lagged relationships using Peter–Clark momentary conditional independence (PCMCI) discovery algorithm. In last step, introduced, assigning weights CMIP6 models' networks. For end-of-century period, 2081–2100, our method reduces very likely ranges (5th–95th percentile) projected between 10 % 16 relative unweighted across three global warming scenarios (SSP2-4.5, SSP3-7.0, SSP5-8.5). The sizes (17th–83rd are further reduced 41 %. not limited can be applied variables, supporting better strategies tackle change.

Dam‐Induced Alternations of Flow and Sediment Regimes in the Tibetan Plateau: An Example of the Yarlung Tsangpo River

Water Resources Research, Journal Year: 2025, Volume and Issue: 61(5)

Published: April 29, 2025

Abstract Dams heavily regulate the natural hydrological regimes, impacting on riverine ecosystem and local communities. Yet, impacts of dams flow sediment alterations in alpine basins, such as Yarlung Tsangpo River with its immense hydropower potential, remain largely understudied due to limited fine‐scale records. Here, we introduced a dynamic alteration index combined wavelet analysis evaluate time‐varying regimes caused by basin from 1980 2020. Leveraging in‐situ daily observation data, first capture both annual intra‐annual trends extending traditional indicators across three regulation scenarios: unregulated, tributary dam‐regulated, mainstem dam‐regulated. We then explore spectral signatures dam‐induced identify most affected timescales assess dam configuration. Our reveals that despite construction, river discharge increased slightly, decreased low‐flow frequency more common high‐flow frequency. Dam operations markedly altered sediment, disrupted periodicities, weakened flow‐sediment relationships. Specifically, reduction was notable under tributary, moderate degree 45.34%, particularly during main flood post‐flood seasons. Dominant periodicities at semi‐annual scales were nearly eliminated, while preserved. Large events high‐magnitude almost absent, figure‐eight hysteresis pattern indicated transport. These findings underscore need for incorporating dynamics into operation strategies minimize negative transport aquatic ecosystems, providing essential insights sustainable water resource management future planning basins.

Abstract A heavy rainfall (HR) event caused by a bow echo struck South China on 11 April 2019. Two extremely HR periods were identified within this event, and the second period led to severe flooding in Shenzhen city, resulting fatalities. The first was dominated warm‐rain processes, while development of closely related intensification ice‐phase processes. contribution raindrops from melting process played crucial role formation extreme rainfall, which achieved high rain rate (RR) exceeding 120 mm hr −1 . enhancement processes during found be associated with low‐level mesoscale vortex (MV). Due complementary non‐linear dynamical accelerations induced MV, vertical velocity convective system rapidly intensified, leading more upright deeper organization. As result, water vapor supercooled lifted above freezing level, increased presence particles potential melt, subsequently contributing RR. This study investigates microphysical characteristics two that occurred after MV examines key affected partially contributed period.
