What is the major cause of the greenhouse effect

Answer 1

The major cause of the greenhouse effect is the increased concentration of certain gases in the Earth's atmosphere, especially carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O). These gases are called greenhouse gases because they trap heat from the sun and prevent it from escaping back into space, thus leading to a rise in the overall temperature of the Earth's surface and the lower atmosphere. Human activities, such as burning fossil fuels (coal, oil, and natural gas), deforestation, and industrial processes, have significantly increased the release of these greenhouse gases into the atmosphere, resulting in the intensification of the greenhouse effect and subsequent global warming.
