Greenhouse Effect and Global Warming: 5 Key Aspects

Greenhouse Effect & Global Warming

Greenhouse effect: Process by which radiation from a planet՚s atmosphere warms the planet՚s surface to a temperature above what it would be without its atmosphere.

Global warming is the climate change observed at century-scale with rise in the average temperature of the Earth՚s climate system

Greenhouse Effect

  • Emission & radiation within infrared range
  • 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
