Arctic Sea Ice Day
July 15 · Level 7 · #889 of 2238
Arctic sea ice is a vast white shield that reflects sunlight and helps keep the planet cool. This day reminds us that the ice is shrinking, and that both the climate and the people and animals of the North depend on it.
How it is celebrated: scientists and environmental groups share satellite images and charts, tell stories about polar bears, belugas and seals, and teachers run lessons on climate. Plenty of people simply enjoy looking at the ice from space.
Arctic sea ice reaches its smallest extent each September and its largest each March. Satellites have tracked it continuously since 1979.
