Use the science of climate and climate change to engage students as you introduce or exemplify many classroom chemistry concepts; for example
• phase change• electromagnetic radiation energy• energy conservation• molecular structure• isotopes• heat capacity• equilibrium• acid-base chemistry

Land and sea ice are disappearing. Why?

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.
