Delger Erdenesanaa covers the environment for The Maine Monitor, explaining and investigating the most pressing energy, water, forestry, fisheries and pollution issues. She also follows one of the biggest issues of them all — climate change, exploring how rising temperatures are reshaping not just the state’s landscapes and seascapes, but also the ways Mainers live and work.

Delger most recently worked at Chemical & Engineering News in Washington, D.C., covering state and federal policy on chemicals in food, agriculture and water. Previously, she has reported for the Pulitzer Center, The New York Times, the Texas Observer and Inside Climate News.
