Climate change intensifies global plastic pollution across ecosystems worldwide

Climate change is rapidly transforming plastic pollution into a more dangerous and far-reaching environmental crisis, according to new scientific research.
The study shows that rising temperatures, extreme weather events and shifting Earth-system processes are making plastics more mobile, persistent and harmful across land, water, air and ice.
Researchers from Imperial College London warn that plastic pollution can no longer be treated only as a waste problem, as climate change is actively reshaping how plastics behave in the environment.
Published in *Frontiers in Science*, the analysis brings together global evidence demonstrating that plastics now function as a climate-sensitive pollutant spreading across ecosystems.
Scientists explain that plastics and climate change share the same fossil fuel roots, with most plastics produced from oil and gas while emitting greenhouse gases throughout their life cycle.
As plastic production has surged since the mid-20th century, emissions linked to manufacturing, transport and disposal have risen alongside global temperatures.
At the same time, warming conditions are accelerating plastic breakdown into microplastics and nanoplastics, increasing their spread through water, soil and the atmosphere.
Floods, storms, wildfires and coastal erosion are remobilizing plastic waste once trapped in landfills, riverbeds and soils, carrying it into oceans and across continents.
Melting sea ice, which previously trapped microplastics, is now releasing concentrated pollution back into marine environments as global temperatures rise.
Higher temperatures also boost the release of toxic chemical additives from plastics while allowing particles to carry harmful pollutants into food chains.
On land, microplastics are interacting with heat stress and rising carbon dioxide levels to disrupt soil health and reduce crop productivity.
In freshwater ecosystems, warmer waters combined with plastic exposure are harming plankton species that support entire food webs.
Marine life such as mussels and fish are showing increased plastic ingestion and weakened immune systems as oceans warm and acidify.
Long-lived species like whales may face especially high risks due to the buildup of plastics alongside climate-related stressors.
Researchers stress that cleanup alone cannot solve the problem as climate change continuously accelerates plastic spread and toxicity.
They argue that cutting plastic production, reducing single-use items, improving recycling and redesigning products for reuse remain the most effective solutions.
Aligning plastic policy directly with climate action is now seen as essential to prevent worsening ecological and health impacts.
The study concludes that plastic pollution and climate change form a reinforcing crisis that must be tackled together through coordinated global strategies.
