Title: Global Warming

Global Warming
  • Emily Neil
  • Charles Bunce
  • Lisa Glowe

Greenhouse Effect
  • The sun radiates thermal energy that the Earth
    absorbs (suns rays).
  • The Earth reemits the energy back as infrared
    radiation (escaping heat).
  • Some of the radiation is reflected by greenhouse
    gases in the atmosphere back down to Earth
    (trapped heat).

3
More greenhouse gases increase
Earth temperatures!

FLOODING
  • Glacial melting (i.e. Greenland) increases sea
    levels.
  • Scientist foresee a 1m increase in sea levels
    would threaten 72 million citizens in coastal
    China alone.
  • The collapse of the W. Antarctic Ice Sheet would
    potentially increase sea levels by 6m, affecting
    over 400 million people worldwide.

5
Drought
  • Droughts in Midwest during the 80s and 90s caused
    mass migration.
  • Tens of thousands moved, leaving behind ghost
    towns.
