Dartmouth’s Institute of Arctic Studies (IAS) in the Dickey Center contributed Arctic expertise to the US National Academies of Sciences, Engineering, and Medicine (NASEM) Climate Crossroads Congressional Fellowship on May 12, when IAS Senior Arctic Fellow Marisol Maddox delivered a briefing on “The Arctic Intersection of Environmental Change and National Security” during the program’s May session on national security and military preparedness. The fellowship equips Congressional staff with scientific and technical knowledge to support evidence-informed policymaking on climate-related issues.

Maddox, an expert in Arctic environmental security and geopolitics, engaged Congressional fellows serving in offices and committees across the U.S. House of Representatives, Senate, Congressional Research Service, and Congressional Budget Office. 

“Marisol’s knowledge continues to inform both national and global discussions about Arctic climate and security,” said Dr. Melody Brown Burkins, Director of Dartmouth’s Institute of Arctic Studies, “The Arctic is increasingly central to critical conversations about climate risk and resilience, geopolitics, infrastructure investments, and community wellbeing. The Institute of Arctic Studies is honored to contribute to evidence-informed policy dialogs both in the US and internationally.”
