Sea ice: A key indicator
Sea ice (frozen seawater) is highly sensitive to a warming climate

Sea ice loss and Canada’s Inuit
50,000 people spread over 53 communities, 35% of Canada’s landmass, and 50% of our coastline

Sea ice loss and Canada’s Inuit
Climate change is hitting Canada’s Inuit the hardest:• Arctic amplification

Sea ice loss and Canada’s Inuit
Climate change is hitting Canada’s Inuit the hardest:• Legacy of European contact/government policies
Employment by whaling/fur trade industries 1700s-1900s.
American military presence in WWII and cold war
Government relocation policies in 1940s-60s
Bigger government role in health care, education, housing in 1960s-70s

Sea ice loss & Inuit communities
Impacts of sea ice melt on Inuit communities:• Coastal erosion
• Economic development
• Hazardous travel
• Ecosystem impacts

Key takeaways
1. Sea ice loss is one of the most dramatic effects of climate change
2. Sea ice loss makes it more difficult for Inuit communities to access traditional resources, compounding existing problems
3. Sea ice loss affects the Arctic marine ecosystem at virtually all levels of the food web
