Scaling laboratory results with machine learning is no silver bullet to strengthen global (micro-)plastic mitigation policy: [Dataset]
Summary
This commentary examines the limitations of using machine learning to scale laboratory microplastic photosynthesis-inhibition results to global estimates, arguing that such approaches are insufficient to reliably inform international plastic mitigation policy without addressing underlying data and model uncertainties.
