An international team of scientists that includes a USDA Forest Service scientist based in New Hampshire used tree rings to document how “Arctic dimming,” the interference with sunlight caused by extreme pollution such as that at an industrial complex in northern Siberia, is killing trees and possibly affecting how trees respond to climate change.

A new project has been launched to remove hormone-changing pollutants from the environment.
