The Greenhouse Effect

Source of Greenhouse Gases

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 (O3): interaction of oxygen in atmosphere with solar/cosmic radiation.

BURNING OF FOSSIL FUELS . . . CO2

Increasing greenhouse gases

↓Increasing greenhouse effect

↓Increasing global warming

Effects of Global Warming1) 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).
