Bethel scientist returns home to study climate change

What happens after fire scorches the tundra, and what follows when carbon that’s been locked away for millennia gets released? Currently, a group of scientists is camping 50 miles north of Bethel are attempting to answer these questions. For one scientist the research is personal because it means coming home.
