The greenhouse effect occurs when greenhouse gases in the atmosphere, such as carbon dioxide and methane, trap heat radiated from the Earth's surface. The greenhouse effect was discovered in 1824 by Joseph Fourier and was later experimentally studied by John Tyndall in 1858 and quantified by Svante Arrhenius in 1896. Greenhouse gases act like the glass of a greenhouse, allowing sunlight to pass through but trapping heat, which warms the Earth's surface and lower atmosphere. Increased levels of greenhouse gases from human activities like burning fossil fuels are enhancing the greenhouse effect and leading to problems such as rising sea levels and health issues.

Green House Effect Presented By: ADITYA BHARTI X D Presented to: AMIT SIR
?The greenhouse effect was discovered by Joseph Fourier in 1824. ?First reliably experimented on by John Tyndall in 1858. ?First reported quantitatively by Svante Arrhenius in 1896.
?The greenhouse effect is a process by which thermal radiation from a planetary surface is absorbed by atmospheric greenhouse gases, and is re-radiated in all directions. ?Since part of this re-radiation is back towards the surface, energy is transferred to the surface and the lower atmosphere. ?As a result, the temperature there is higher than it would be if direct heating by solar radiation were the only warming mechanism.
?The greenhouse effect is a warming near the Earth's surface that results when the Earth's atmosphere traps the sun's heat. ?The atmosphere acts much like the glass walls and roof of a greenhouse.
Green House Gases Burning of Oil, Petrol Engine Industrialization Burning of Fossil Fuel CFC NOX +Co2 NO+Co2 NOx + Co2 CFC Much of it remains trapped in the atmosphere by the greenhouse gases, causing our world to heat up NH4
