Impact of Climate Change on Aulavik National Park

Changes in Climate, Hydrology, and Geomorphology

  • These changes will affect vegetation and cultural features in the park
  • More wet snow accumulation
  • Increased spring runoff volumes
  • wetter soils
  • faster river currents
The warmer temperatures can also lead to earlier spring melts, soil thawing, and longer open water seasons.

Sea Level Rise

  • 0.6 to 0.9 meters per century
  • Submergence rate of 0.1 to 0.4 global sea levels
  • combined effects can put parks coastal areas at risk
  • increased shoreline
  • saltwater intrusion

Animal Endangerment

  • Home to endangered Peary caribou
  • Largest amount of Muskoxen
  • Two bird species reside in the park year round
  • 50 other bird species migrate to the park
  • Aulavik park is completely treeless
