spring/summer is a source
of water for some regions
Permafrost
• Shifting of buildings
• Drainage of tundra lakes
• Rapid decomposition

Now review your notes on CLIMATE
CHANGE
• Sources of long term data
– Temperature
– Carbon Dioxide.
Examples
• Twin Cities now trucks in snow some years for
their ski races
• Badger State Winter Games may be leaving
Wausau
• Birkie hit 47 degrees in 2010,
• Birkie was -10 in 2011,
