From production to degradation: exploring the connection between microplastics and climate change
AI summary Read the abstract
This review pulls together existing research showing that plastic and climate change are more connected than most people realize: making, shipping, and breaking down plastic all release greenhouse gases, while extreme weather from climate change washes even more plastic waste into our oceans. This matters because these tiny plastic bits can interfere with the ocean's natural ability to absorb carbon, potentially making climate change worse, and as microplastics build up in marine life and waterways, they increasingly end up in the food and water we consume too.
The extensive manufacturing and use of plastics have led to their infiltration into the environment. Yet, the connection between microplastic pollution and climate change is largely unexplored. The entire plastic lifecycle, including production, transportation, waste and degradation contributes to an increase in greenhouse gas emissions. Extreme weather events caused by climate change can increase the distribution of plastic litter that reaches the marine environment. Plastic pollution and climate change could cause alteration to carbon sequestration and impact marine carbon pumps. This review discusses plastic’s contribution to climate change; plastic degradation and climate change in the marine environment and biofilm’s role in microplastic degradation in the marine environment. Recommendations are offered for plastic mitigation.

Microplastic Pollution in the Changing Climate
AI summary Read the abstract
This review examined how climate change is altering microplastic transport, distribution, and persistence — with warming oceans, intensified storms, glacial melt, and shifting wind patterns redistributing particles into previously uncontaminated remote regions. Climate change and microplastic pollution are not independent crises; their interaction means that as warming accelerates, plastic particles will penetrate deeper into food webs and human communities that currently have minimal exposure.
Understanding and addressing the environmental risk of microplastics
