What is the major cause of the greenhouse effect?

Answer 1

The major cause of the greenhouse effect is the increasing concentration of greenhouse gases in the Earth's atmosphere. These gases, such as carbon dioxide, methane, and nitrous oxide, trap heat from the sun and prevent it from escaping back into space, resulting in a warming of the Earth's surface. Human activities, such as burning fossil fuels and deforestation, are the main sources of these greenhouse gases.
