Global warming is a slow but steady rise in Earth's surface temperature.
Temperatures today are 0.74 °C (1.33 °F) higher than 150 years ago.
Some people think that the warming is because of people burning fossil fuels like coal and oil. Some also think that humans are cutting down too many of the Earth's forests, a process known as deforestation.
Most major governments and science groups agree with these ideas.
