Emerging challenges of microplastic impacts to ecological health and climate change
AI summary Read the abstract
This review examines how microplastics contribute not only to environmental pollution but also to climate change by altering microbial processes, disrupting biogeochemical cycles, and promoting greenhouse gas release. Researchers found that microplastics affect carbon cycling, phytoplankton photosynthesis, and atmospheric processes in ways that may exacerbate global warming. The study highlights significant knowledge gaps in understanding the mechanisms linking microplastic pollution to greenhouse gas emissions.
Microplastics (MPs) pose a serious environmental hazard, contributing to pollution and potentially impacting greenhouse gas (GHG) emissions and climate change trends. This study addresses this critical gap by conducting a comprehensive review of existing literature to consolidate current knowledge on the ecological and climatic challenges posed by MPs. Through this review, we find that MPs alter microbial processes, disrupt biogeochemical cycles, and promote GHG release through degradation and ecosystem interactions. The review highlights that MPs not only impact biodiversity and ecosystem health, but also exacerbate climate change by influencing carbon cycling, photosynthetic dynamics in phytoplankton, and atmospheric processes. However, knowledge gaps remain regarding the mechanisms linking MPs to GHG emissions and long-term ecosystem impacts. Our findings emphasize the urgent need for systematic research, standardized methodologies, and integrated policy strategies to mitigate the dual threats of plastic pollution and climate change.

Microplastic pollution as an environmental risk exacerbating the greenhouse effect and climate change: a review
AI summary Read the abstract
Researchers reviewed how microplastics contribute to climate change by releasing greenhouse gases as they degrade, disrupting plant photosynthesis, and altering soil microbial communities that regulate carbon and methane emissions. The review reveals a troubling feedback loop: microplastics worsen global warming, and rising temperatures cause more microplastics to be resuspended from sediments, further intensifying environmental contamination.
Role of Microplastics in Global Warming and Climate Change: A Review
AI summary Read the abstract
This review examines how microplastics contribute to climate change through multiple pathways, including disrupting ocean carbon capture by phytoplankton, releasing greenhouse gases from soil, and potentially influencing cloud formation in the atmosphere. Researchers found that climate-driven extreme weather events also redistribute microplastics, creating a feedback loop that worsens both problems. The study makes the case that microplastic pollution and climate change should be addressed as interconnected challenges.
From pollution to ocean warming: The climate impacts of marine microplastics
AI summary Read the abstract
This review examined the largely overlooked role of marine microplastics in driving climate change, covering how they disrupt oceanic carbon pumps, alter biogeochemical cycling, and directly emit greenhouse gases during UV degradation. The authors found that microplastics reduce the efficiency of the biological carbon pump by impairing marine organisms that sequester carbon, creating a feedback loop between plastic pollution and ocean warming.
Bridging the gap: a review on the interaction between (micro)plastics and climate change
AI summary Read the abstract
This review examined the two-way relationship between climate change and microplastic pollution. Researchers found that climate-driven changes like rising temperatures, altered weather patterns, and ocean acidification can accelerate microplastic breakdown and redistribute particles across ecosystems, while plastic production and degradation processes themselves contribute to greenhouse gas emissions, creating a reinforcing cycle.
Microplastics and climate change: the global impacts of a tiny driver
AI summary Read the abstract
This review explores the connections between microplastic pollution and climate change, two environmental crises that are more intertwined than they might appear. Researchers found that microplastics disrupt ocean carbon sequestration by affecting plankton, may accelerate ice cap melting by reducing surface reflectivity, and can influence greenhouse gas emissions from both water and soil. The study argues that addressing microplastic pollution should be considered an integral part of comprehensive climate change strategies.
