greenhouses gases

Greenhouse gases are atmospheric molecules like carbon dioxide, methane, and nitrous oxide that trap heat from the sun, creating a natural warming effect on Earth’s surface. They allow sunlight to enter, warming the planet, but then absorb and re-radiate some of that heat, preventing it from escaping back into space. This process is essential for maintaining a habitable climate. However, human activities such as burning fossil fuels and deforestation have increased the concentration of these gases, intensifying the greenhouse effect and leading to global warming and climate change.
