The Greenhouse Effect
Source of Greenhouse Gases
Carbon Dioxide: burning of fossil fuels, animal respiration Water Vapor: evaporation from ocean surface; transpiration from forests Methane: rotting garbage, animal gas (ok... farts!!!!) Ozone (O 3 ): interaction of oxygen in atmosphere with solar/cosmic radiation.
BURNING OF FOSSIL FUELS... CO 2
Increasing greenhouse gases ↓ Increasing greenhouse effect ↓ Increasing global warming
Effects of Global Warming 1)Glaciers melt at poles 2) Sea level rise, coastline flooding, property damage 3) Habitat destruction & species extinction 4) Drought & Famine 5) Climate Change (stronger hurricanes and tornadoes; colder winters/blizzards, hotter summers).
