Electromagnetic radiation and planetary energy balance
Energy balance: solar energy in = planet radiant energy out
(mostly visible) (thermal infrared)

Electromagnetic radiation and planetary energy balance
Energy imbalance: solar energy in > planet radiant energy out

The Science of Climate in the Classroom
Electromagnetic radiation and planetary energy balance
Energy balance is attained when the planet is warm enough to emit
sufficient energy to compensate for the atmospheric trapping.

Electromagnetic radiation and planetary energy balance
Since the Industrial Revolution, burning fossil fuels (coal, oil, & gas) has
added large amounts of greenhouse gases to Earth's atmosphere.

Electromagnetic radiation and planetary energy balance
Due to the energy imbalance (more in than out), Earth is warming as
the extra energy is being stored.

Oceans' role in climate science
Oceans store energy, move it around the planet in great currents, and
dissolve carbon dioxide.
