- 1. The greenhouse effect is a natural phenomenon that occurs when certain gases in Earth's atmosphere trap heat, preventing it from escaping back into space and thereby warming the planet. This process begins when the sun's energy reaches the Earth, with a portion of this energy being absorbed by the surface, which then re-radiates it as infrared radiation. Greenhouse gases, including carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and water vapor, absorb this infrared radiation and emit it in all directions, including back towards the surface, which leads to an increase in temperature. While the greenhouse effect is essential for maintaining the planet's habitable climate, human activities, such as burning fossil fuels, deforestation, and industrial processes, have significantly increased the concentration of these gases in the atmosphere, intensifying the effect and contributing to global warming and climate change. As a result, the delicate balance of Earth's climate system is disrupted, leading to various environmental challenges, including rising sea levels, extreme weather events, and loss of biodiversity, making it crucial to understand and mitigate the impacts of this phenomenon.
