Understanding the Greenhouse Effect

The greenhouse effect is a natural process that warms the Earth's surface. When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space, while the rest is absorbed by the Earth's surface. This absorbed energy is then radiated back into the atmosphere as heat. Certain gases in the atmosphere, known as greenhouse gases, trap some of this heat, keeping the Earth warm enough to support life. The primary greenhouse gases include water vapor, carbon dioxide, methane, nitrous oxide, and ozone.

However, human activities such as burning fossil fuels, deforestation, and industrial processes have increased the concentration of these gases in the atmosphere. This enhanced greenhouse effect leads to global warming and climate change, with far-reaching consequences for ecosystems and human societies.
