The atmosphere is a mixture of gases around Earth.
Carbon dioxide is a greenhouse gas that makes up about 0.04% of the atmosphere and is released when we burn fuels.
Greenhouse gases in the atmosphere trap heat that warms Earth.
Increasing carbon dioxide levels in the atmosphere raises average temperatures on Earth.
Temperature data shows evidence of Earth warming up more quickly in the last 50 years.

Pupils often think that global warming means that the weather is getting warmer everywhere.

Emphasise that not everywhere gets warmer all the time. Some places might experience colder weather, more storms, or other changes in climate.

Carbon dioxide - Carbon dioxide is a type of gas found in Earth’s atmosphere.
Greenhouse gases - Gases which contribute towards global warming are called greenhouse gases.
Temperature - Temperature is a measure of how hot or cold something is.
Evidence - Evidence is information which helps us to prove that something is true or not true.
Climate change - Climate change is when the long-term weather patterns change.
