Climate Chemistry: CO₂ & Temperature
Change CO₂ levels and see the greenhouse effect warm the planet.
Average surface temperature0 °C
Change vs pre-industrial0 °C
CO₂ level0 ppm
Extra heat trapped0 W/m²
What you can learn
- Greenhouse gases absorb infrared heat that the Earth radiates.
- More CO₂ traps more heat, raising the equilibrium temperature.
- Without any greenhouse effect the Earth would average about −18 °C.
Frequently asked questions
How does CO₂ make the planet warmer?
CO₂ molecules absorb infrared radiation leaving Earth and re-emit it in all directions, some of it back downward, which warms the surface.
Is the greenhouse effect bad?
No, it is natural and keeps Earth habitable. The concern is extra greenhouse gases from human activity strengthening it.
