Reindeer Populations Could Plunge 80% by 2100
A new international study warns that Arctic reindeer could decline by up to 80% by 2100 due to rapid climate change. Using paleogenetics and climate models, researchers forecast severe impacts on biodiversity, tundra ecosystems, and Indigenous livelihoods—especially in North America. Urgent conservation, reduced emissions, and habitat protection are vital to safeguard reindeer and Arctic resilience.
