How do greenhouse gases contribute to warming the atmosphere?

Greenhouse gases play a crucial role in warming the atmosphere by absorbing heat and releasing it in all directions. This process is often referred to as the greenhouse effect. When solar radiation reaches the Earth's surface, some of it is absorbed, warming the planet. The Earth then emits heat in the form of infrared radiation. Greenhouse gases, such as carbon dioxide, methane, and water vapor, absorb this infrared radiation and re-radiate it back towards the Earth's surface, effectively trapping heat in the atmosphere and preventing it from escaping into space. This natural mechanism is essential for maintaining a habitable climate, as it helps to keep the Earth's temperature at a level conducive to life.
