Infographic 4 — The Canadian Arctic: Sea ice is changing in different ways

An infographic shows different ways sea ice is changing in the Canadian and Central Arctic. A map is shown in a circle of the high Canadian Arctic. At top left are icons indicating changes occurring in the Central Arctic Ocean including a calendar with dripping water, chunks of sea ice, turning into smaller more fragile sea ice, and arrows indicating winds and water currents that move the ice. An arrow points towards the top of the Canadian Arctic where an ice refuge is described. At bottom left are icons indicating changes occurring in the Canadian Arctic including a calendar with dripping water, an Inuk standing on the ice edge by several chunks of sea ice. Two down arrows are shown indicating thinning sea ice. At bottom right is a chunk of sea ice with text describing the thickness of old ice.

• Central Arctic Ocean
• Melting earlier, freezing later
• Significant loss of old ice
• More fragile and mobile ice cover
• Winds and currents push old ice to Canadian waters
• Canadian Arctic
• Melting earlier, freezing later
• Ice edge locations documented by Inuit knowledge
• Sea ice is thinning
• 40 cm/decade over deep Canada Basin
• <10 cm / decade on shallow continental shelf
• Ice refuge
• Only Arctic area expected to have summer sea ice in the future
• Thickness of old ice has not changed since 1970s in some parts of the Canadian High Arctic
