When did global warming change into climate change?

When people tried to understand what was happening we started talking about climate change (as well as global warming).

Global warming is the cause. Climate change is the result. They are really two different things.

Burning of fossil fuels (coal, oil and natural gas) and deforestation (cutting down trees which previously removed carbon dioxide (CO2) from the atmosphere) put extra greenhouse gases into the atmosphere.

These gases trap more of the sun's heat (greenhouse effect), causing global warming.

The warming of the earth, the atmosphere and the oceans has one huge effect. It is changing the climate.
