What is global warming?
<|assistant|>
Global warming is the gradual heating of the planet due to increases in average global temperature resulting from the rise of certain gases like carbon dioxide in the Earth's atmosphere. This is caused by human activity such as burning fossil fuels and deforestation, among other factors. It can result in extreme weather, ocean acidification, and the extinction of plant and animal species.
