Global warming is the temperature of the Earth’s surface rising.

Humans are adding to the amount of greenhouse gasses in the air by doing things like burning coal for electricity. A warmer earth means that the icecaps are melting which means the sea levels are rising and some places, like Venice in Italy, are already underwater. Where it is already hot it is getting even hotter. A lot of Australia is on fire because it is so dry due to it being so hot.
