I've been hearing a lot about global warming lately, but I'm not sure what it means.

Global warming is the long-term increase in average temperatures on Earth caused by human activities such as burning fossil fuels and deforestation. It can have serious consequences for people and the environment, including rising sea levels, changes in weather patterns, melting glaciers, and more frequent and intense extreme weather events like hurricanes, floods, droughts, and heat waves.
