Arctic Haze
Connections to NRC Framework for K-12 Science Education: Disciplinary Core Ideas: ESS3.C Human Impacts on Earth Systems.
As you just saw, Marisol was concerned about the local impacts of the coal-burning plant near her community. In fact, researchers have found that such impacts can extend to distant parts of the globe. In the Arctic region, once clear blue skies have become less transparent because the long-range transport of particles around the globe brings pollution to the Arctic. This haze may directly impact human health and contribute to climate change. Click on the left to watch this video about the haze in the Arctic region.
How do you think governments should approach this problem? How might you or your students learn more about the problem of Arctic haze?
