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
