OVERVIEWStatus of North Pole
June 2011 average was 11.01 million square kilometers (4.25 million square miles).
Kara Sea region has prominent low ice extent.
Ice break up off the coast of Alaska in the Beaufort Sea

OVERVIEWStatus of North Pole
Arctic sea ice extent decline in recent years
Ice thickness decreased
NASA sea ice breakup
Ocean heat increased

OVERVIEWGlobal Role
Provides a certain amount of stability to the weather.
Affects the ocean circulation and worldwide climate.
Unique ecosystem that houses a diverse and different biodiversity.

ECOSYSTEM
North Pole Location
450 miles north of GreenlandDepth of the sea: 13, 410 meters
Diametrically opposite the South PoleSea ice is 2-3 m thick
Limited Primary ProductionTundra Biome
North Pole Climate
Warmer than the south poleSituated in the polar climate zone
North pole temperature: Winter: -34 C Summer: 0 C
Sun is above the horizon during summer months and below the
horizon during the winter months

EFFECTSMelting Polar Ice Caps VS Biodiversity
Increased tree growth
Increase in population of migratory species
Decrease habitat for Arctic animals
More mobility of marine animals
Polar Bear Extinction
