1. What is green house effect? The greenhouse effect first discovered by Joseph Fourier in 1824. The greenhouse effect first investigated quantitatively by Svante Arrhenius in 1896. Earth surface temperatures in the 20th century raised by 0.6 ° C. Scientists believe that global warming is the result of CO2, CH4, N2O - the main culprit for the greenhouse effect. They are caused by human activity - an industrial boom, the increased use of fossil fuels such as coal and oil, the felling of large forest masses, etc. Greenhouse gases pass through the solar radiation to the Earth's surface, but they absorb the infrared heat rays and heat the earth's surface and the ground atmosphere layer. 2. Greenhouse Gas (GHG) Gases in the atmosphere, both natural and anthropogenic, that are capable of absorbing and re-emitting infrared radiation. Water vapour, carbon dioxide, nitrous oxide, methane, and ozone are the primary greenhouse gases in Earth's atmosphere. Greenhouse gases transfer their absorbed energy to other molecules through collisional de-excitation. This increases the kinetic energy of other molecules, such as nitrogen and oxygen, thereby increasing the temperature of the air. Use care with this term, as the process by which heating occurs in the atmosphere is very different than in a greenhouse. As a result of the changes, the icy shell of the poles melts. Arctic and Antarctic warming and the melting of ice blocks cause a rise in the sea level and flood of fertile lowlands and coasts. Changing the amount of rainfall on the ground, resulting in unpredictable frequent floods or prolonged droughts. All these changes can be summarized in one notion - 'climate change'. What will be if not atmosphere?
