Title: Arctic and Antarctic Ecosystems


1
Arctic and Antarctic Ecosystems
  • The Effects of Global Warming
  • Samantha Brovko

3
Arctic Ecosystem
  • Some Facts
  • Includes land from 8 Nations
  • Ocean surrounded by land mass
  • Sea Ice and some Land-based Ice
  • Climate Changes Amplified
  • Mostly Icebergs and Sea Ice
  • Ice Albedo gtgt Water Albedo
  • Not as much ice as Antarctic
  • Lots of Cooling Power

4
Arctic Ecosystem
  • More People Live Here
  • Increased Stress on Environment and Resources
  • Diverse Wildlife and Plant Life
  • More Organisms to be Affected
  • Provides Natural Resources to the World
  • Highly Variable Region

5
Arctic Ecosystem
  • Arctic Warming Global Implications
  • Arctic Vegetation Moves North
  • Animals and Resources
  • Coastal Storms
  • Melting Permafrost
  • Indigenous Communities

7
Antarctic Ecosystem
  • Some Facts
  • 10 Land mass
  • 14 Million square kilometres
  • Three regions East, West and Peninsula
  • Average ice depth of 2 kilometres
  • Climate Changes Amplified
  • Ice Albedo gtgt Water Albedo
  • Enhances cooling power of the Antarctic
  • Heat sink of the Southern Hemisphere

8
Antarctic Ecosystem
  • Considerable year-to-year variations
  • Key in production of Ocean bottom water and
    dense, saline ocean water
  • Deep Sea Marine Life
  • Around 30 million cubic kilometres of ice
  • Sea Level
  • Warmer Temperatures a Thinner ice, lower albedo,
    more heat
  • Global Climate Changes

9
Arctic and Antarctic Ecosystem
  • Current Technologies are Inefficient
  • Present Models Break Down for Polar Region
    Predictions
  • Cannot accurately represent outcome of global
    climate change in the region
  • Which Aspect is the Biggest Contributor?
