Climate change
Climate change is a long-term change in weather patterns and average temperatures in the global climate over a period of time. It is caused by human activities such as the burning of fossil fuels, deforestation, and overpopulation, as well as natural processes such as volcanic eruptions and changes in the Earth's orbit. These changes can have a variety of effects on the environment, from causing extreme weather events to rising temperatures and sea levels.
