Smart Stuff with Twig Walkingstick: Who Else Needs the Arctic? (for the Week of Jan. 13, 2007)

January 16, 2008

Q. Dear Twig: What about other Arctic animals? If the ice cap melts, what will it mean to them?

A.: Certain seals — ringed, ribbon and bearded seals — need sea ice. They give birth to and nurse their pups on it. They rest on it. They hunt near and under it. "Adapting to life on land," says a report called the Arctic Climate Impact Assessment, "seems highly unlikely for these species."

Millions of birds — ducks, geese, others — fly north to nest on the tundra (frozen Arctic ground) in summer. The tundra, however, might shrink or thaw or even sprout trees due to melting. "Important breeding and nesting areas," the same report says, "are projected to decrease sharply."

Reindeer and caribou eat plants on the tundra. They raise their young on the tundra, too. Melt-caused changes will change how well and how many of them survive.

Arctic people in turn need these animals. They need them for their food and culture. What would they, and all of us, do without them?

P.S. People of the Arctic include the Aleuts, Gwich'in, Saami, Inuit and Athabascan.

Notes: Different spellings exist for many of the names of Arctic people. For example, Sami instead of Saami, Athapascan instead of Athabascan, Kutchin or Gwitchin for Gwich'in.
