History of Greenhouse effect

• Svant Arrhenius (1859-1927) Swedich scientist.

• 1896: He was the first to claim that fossil fuel combustion may eventually result in enhanced global warming.

• He found that the average surface temperature of the earth is about 15°c because of the infrared absorption capacity of water vapor and carbon dioxide.

• He suggesed a doubling of the carbon dioxide concentration would lead to a 5°c temperature rise.

Definition and mechanism of Greenhouse efffect

Causes of Greenhouse effect

• The main reason for Greenhouse effect is the emission of gases like nitrous-ioxide, carbon dioxide, methane, ozone and water vapor. The causes of these emissions have been listed below.

Causes of Greenhouse effect

Deforestation

Burning of fossiel fuels

Electrical appliances

Industries

Automobiles

Population growth

Consequences of Greenhouse effect

• Rise of the level of the seas .

• Climatic altertions in all the planet.

• Increase of the terrestrial and oceanic biomass.

• Deep modifications in the typical vegetation of each region and altitude.

• Increase in the incidence of illnesses and proliferation

Wayes to reduce Greenhouse effect

• Reduce, reuse, recycle.

• Use less heat and air conditioning

• Replace your light bulbs

• Buy energy-efficient products

Wayes to reduce Greenhouse effect

• Use less hot water

• Use the « off » switch

• Plant trees

• Encourage others to conserve energy

• Drive less drive smart

Conclusion

• From 1998 onwards the terminology on the Greenhouse effect started to change as a result of media influences. The Greenhouse effect as a term was used less and less and people started to refer to the theory as either global warming or climate change.
