What climate change impacts are expected in Canada's Arctic regions?

• A. Sea-level rise and other impacts
• B. No significant changes expected
• C. Permafrost thaw and sea-ice retreat, warming temperatures, changes in traditional hunting and fishing, infrastructure challenges
• D. Decreased temperatures

Answer: (C)

In the Arctic, climate change brings rapid warming, which sets off a chain of connected effects that directly touch both the land and the people who depend on it. Warmer temperatures cause permafrost to thaw, destabilizing the ground that many communities, roads, and infrastructure sit on. At the same time, sea ice is retreating and forming for shorter seasons, altering marine ecosystems and making traditional hunting and travel by ice more difficult. These physical changes also ripple into wildlife patterns, affecting hunting and fishing practices that communities have relied on for generations. All of this together creates infrastructure challenges—from shifting ground to coastal erosion and higher maintenance costs for remote areas. That combination—permafrost thaw, sea-ice retreat, warming temperatures, impacts on traditional hunting and fishing, and infrastructure challenges—best describes what climate change is expected to bring to Canada’s Arctic regions.
