Meet the Inuit scientist kayaking around Greenland to highlight just how far microplastics travel
A decade-long investigation by Inuit scientist Kristian Louis Jensen has revealed a disturbing new dimension to microplastic pollution: the presence of car tire particles in the remote glaciers of eastern Greenland. Jensen’s work, stemming from his Master’s degree research and utilizing a citizen-science tool called ‘The Plastaq’, highlights how pervasive plastic contamination has become, extending far beyond urban centers and impacting even the most pristine environments.
The Discovery in Greenland
Jensen, while kayaking in one of the Arctic’s most isolated corners – hundreds of kilometers from any road – initially expected to find typical plastic debris. However, the discovery of car tire particles was a shock. He describes this finding as validating a “terrifying thesis” that these particles are no longer localized to cities but have become airborne dust, travelling thousands of kilometers to the Arctic.
Impact on Arctic Ecosystems and Communities
The presence of microplastics, and specifically tire particles, is creating a “trifecta of problems” for Greenland. Early evidence suggests tire toxicity is harmful to Arctic species, with chemicals like 6PPF proving lethal to Coho salmon. Car tire pollution is linked to deformities in Atlantic cod eggs, potentially threatening Greenland’s fishing industry.
For Indigenous communities, the pollution represents an environmental justice issue, posing serious health risks. Exposure to these particles has been linked to worsening asthma and cardiac problems in urban areas, and now that threat is extending to food sources in the Arctic.
‘A Critical Blind Spot’ in Regulation
Jensen argues that current climate policy overlooks a crucial aspect of plastic pollution: tire wear. While regulations address tailpipe emissions, the particles released from tires are largely ignored, despite being a leading source of microplastics globally. This regulatory gap is particularly concerning given that more than five billion tires are currently in use worldwide.
The Role of Fossil Fuels and Future Action
While momentum is building to transition away from fossil fuels – with over 90 countries backing a roadmap at COP30 – Jensen points out that the focus is primarily on ‘black carbon’ emissions from burning fuel. He argues that the conversation must expand to include ‘carbon black,’ the fossil fuel-derived filler that constitutes a significant portion of tires. Ignoring this component, he states, means failing to fully address the fossil fuel crisis.
To address this, Jensen is launching the Black Carbon scientific coalition at the Arctic Frontiers conference. This coalition will bring together toxicologists, Indigenous leaders, and policymakers to investigate the impacts of tire particles on Arctic health and advocate for national and international commitments to reduce emissions. A documentary, “Black Carbon,” is also in production, aiming to expose the devastating impacts of microplastics on the Arctic.
Frequently Asked Questions
What did Kristian Louis Jensen discover in Greenland?
Kristian Louis Jensen discovered traces of car tire particles on a remote glacier in eastern Greenland, demonstrating that microplastic pollution extends to even the most isolated areas of the Arctic.
What is ‘The Plastaq’?
‘The Plastaq’ is a citizen-science tool developed by Kristian Louis Jensen during his Master’s degree, allowing kayakers and local communities to collect surface water samples containing debris like plastic and packaging.
What is the significance of the Black Carbon coalition?
The Black Carbon coalition aims to monitor black carbon and carbon black in the Arctic, investigate their impact on Arctic health, and advocate for national and international commitments to reduce emissions.
As the Arctic becomes a “sink” for global pollution, what steps can be taken to ensure a more sustainable future for these fragile ecosystems and the communities that depend on them?
