The impact of climate change induced extreme weather events on microbial dynamics and public health: an in-depth review on water quality and ecosystem resilience
AI summary Read the abstract
This review examined how climate change-induced extreme weather events — floods, heatwaves, droughts — affect microbial dynamics in water systems and public health outcomes. The authors link increased pathogen exposure, harmful algal blooms, and antibiotic resistance spread to extreme weather impacts on aquatic microbial communities.
Climate change is significantly increasing the frequency and intensity of extreme weather events (EWEs), including severe storms, catastrophic floods, prolonged heatwaves, and extended droughts. These events have significant impacts on hydrological systems, microbial ecosystems, and public health. Therefore, this detailed review was carried out to explore the impact of climate change induced extreme weather events on microbial contamination and public health. The detailed search revealed that EWEs can lead to increased microbial contamination in water sources, potentially causing outbreaks of waterborne diseases. In addition, EWE can also disrupt nutrient cycles and alter microbial community structures, affecting ecosystem stability and resilience. Moreover, EWEs can mobilize pollutants such as microplastics, antibiotic-resistant genes, and PFAS, further degrading water quality. Despite these challenges, microbial communities can play a crucial role in mitigating the impacts of EWEs by degrading pollutants and stabilizing nutrient cycles. In addition, we found that real-time monitoring techniques, such as environmental DNA (eDNA) profiling, can help identify contamination sources and inform targeted interventions. At last, we observed that integrating microbial insights into ecosystem management and public health strategies is essential for developing resilient and adaptive approaches to address the escalating impacts of climate change on water quality and public health. Therefore, this study is particularly important in highlighting its contribution to the development of more effective and resilient management practices in the face of increasing climate variability.

Microplastics and Emerging Contaminants Under Climate Change and Extreme Hydrological Events: A Nexus Perspective for Environmental Sustainability
AI summary Read the abstract
This review paper looks at how climate change, things like floods, droughts, and heatwaves, can make microplastic pollution and other harmful chemicals in our water and soil worse by helping them spread further and interact in unpredictable ways. That matters because these tiny plastic particles can carry toxic chemicals into our drinking water and food supply, and extreme weather (which is becoming more common) may make this problem harder to control. The researchers suggest solutions like better wastewater treatment and safer plastic alternatives, but emphasize that tackling climate change and plastic pollution together, rather than separately, is key to protecting public health.
Climate change and microplastic pollution in aquatic ecosystems: ecological and societal consequences
AI summary Read the abstract
This review examines how climate change amplifies the ecological and societal impacts of microplastic pollution in aquatic ecosystems. The study suggests that rising temperatures, extreme weather events, and altered precipitation patterns accelerate plastic fragmentation and dispersal, creating compounding effects on water quality, biodiversity, and coastal communities.

AI summary Read the abstract
This review explores how climate change and antibiotic resistance are connected health emergencies, with microplastics playing a role as carriers that help spread resistant bacteria through waterways. The findings suggest that rising plastic pollution in water systems may contribute to the spread of drug-resistant infections, which is a growing threat to human health.
Microbiomes of the Aquatic Environment
AI summary Read the abstract
This review examines the diversity and ecological roles of microbial communities in aquatic environments, covering microbiomes associated with aquatic insects, plants, fish, phytoplankton, macrophytes, and microplastics, and their interconnected functions in nutrient cycling and primary production. The authors discuss how climate change, eutrophication, and pollution are shifting microbial community composition in ways that threaten the functioning of freshwater and marine ecosystems.
