1. Sunlight passes through the atmosphere and warms the Earth’s surface.
2. The warm surface gives off heat as infrared radiation trying to go back to space.
3. Greenhouse gases (CO2, methane, water vapor, etc.) absorb and re‑emit much of that infrared radiation, trapping heat in the atmosphere like a blanket — the more gases, the more heat is trapped.
4. That trapped heat raises the planet’s average temperature; warmer air also holds more water vapor, which causes additional warming (a positive feedback).
