1st disc. by Joseph Fourier in 1824
1st experimented by John Tyndall in 1858
1st reported quantitatively by Svante Arrhenius in 1896

Global-Warming Potential (GWP)
Relative measure of heat being trapped by GHGs in atmosphere
Compares total heat trapped by certain mass of gas to total amount of heat trapped by a similar mass of CO2

Causes of Global Warming
Deforestation
Rise of GHG
Population explosion
Industrialization
Change in agricultural methods
Volcanic Activities
Sunspots
Wobbly Earth

Impacts
Rise of Temperature
Rise of Sea level
Storms and floods
Droughts
Melting of ice
Increase in Diseases
Impact of Ocean
Loss of Habitat
Cold & warm gulf stream alteration caused by desalination of Atlantic Ocean
