In response, this study reviews the power of Artificial Intelligence (AI) to develop advanced predictive models for assessing the multifaceted impacts of climate change. The study used the PRISMA framework to find, assess, and combine research on using AI in predicting climate change impacts. Integrating AI techniques, such as machine learning algorithms and predictive analytics, into climate modeling provides a robust framework for understanding and projecting the complex dynamics associated with global climate change. These models exhibit a high capacity for data collection, analyzing intricate patterns and integration, including their relationships within the datasets. They enable quick and accurate predictions of future climate scenarios, scenarios testing, historical eventualities, their magnitude, and adaptation. However, challenging issues like data gaps, especially in interconnected systems such as the atmosphere, are associated. Also, AI insight translation into an actionable recommendation recognizable by the policymakers, including ethical usage, is an emerging concern. Therefore, further advances to circumvent these will include the integration of AI with physical models, developing hybrid models, and generating synthetic climatic datasets to enhance data quality and gaps. Also, AI tools are being developed to aid decision-making for policy integration. AI-based predictive modeling is restructuring and bringing reformative change to the understanding of and approach toward climatic change through AI model development. AI guarantees an unfailing plan and a resilient future with sustainable approaches that empower scientists, policymakers, and communities.</p>","PeriodicalId":545,"journal":{"name":"Environmental Science and Pollution Research","volume":" ","pages":""},"PeriodicalIF":5.8,"publicationDate":"2025-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143778688","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Adsorption assays were conducted under various experimental conditions, including agitation rate, pH, temperature, effluent concentration, and MCP concentration. The adsorption capacity was modeled using Langmuir, Freundlich, Dubinin-Radushkevich, and Temkin isotherms, with Langmuir providing a better fit (R<sup>2</sup> = 0.9884), indicating indicating a monolayer adsorption of Cr ions onto the MCPs surface. Results showed a maximum adsorption capacity of 28.17 mg/g for Cr, with optimal conditions identified as 400 rpm agitation, pH 5.0, 35 °C temperature, and 25 mg/L MCP concentration. Multiple regression analysis highlighted pH and effluent dilution as significant factors affecting adsorption efficiency. Additionally, cluster analysis and Detrended Correspondence Analysis (DCA) confirmed the complex interactions among the variables. Our findings suggest that mercerized MCPs are a promising and sustainable solution for Cr removal from tannery effluents, offering a high adsorption capacity and potential for environmental application.

The SPR effect of Ag NPs significantly improved the electron transfer characteristics of GCN, leading to enhanced separation efficiency of electron-hole pairs.

The morphological and structural properties of the obtained NFs were investigated by scanning electron microscopy, Fourier transform infrared spectroscopy (FTIR) and thermogravimetric analysis.

Porphyrin-doped PAN NFs produced under different optimization conditions exhibited different color tones as a result of electrospinning, and FTIR analysis results also supported the color analysis results. It was observed that PAN-P and PAN-P2 NFs exhibited the most successful cross-linking to the polymer with the characteristic peaks of porphyrin at 802 <span>(:{cm}^{-1})</span> and 803 <span>(:{cm}^{-1})</span>, respectively. Furthermore, it was observed that as the applied voltage during electrospinning increased, more porphyrin molecules were deposited onto the fiber surface of PAN. This phenomenon can be attributed to the electrostatic force applied to the porphyrin molecules. Additionally, PAN-P NFs to which a relatively higher voltage value was applied exhibited a darker color than PVA-P NFs.
