The Microplastics in the Baltic project is assessing the impact of plastic in biodiversity, climate change and human health in the Baltic region. IUCN is leading the first worldwide project to study the possible impacts of plastic in ice formation and melting. We will understand if plastic has any impact in sea ice formation, how much plastic is actually "scavenged" from the water and incorporated in ice and if plastic (at high concentrations) can play a role in ice melting.
