Climate change refers to the long-term changes in the Earth's climate, including changes in temperature, precipitation, and weather patterns, that have been observed over several decades or longer. These changes are primarily caused by human activities, such as burning fossil fuels and deforestation, which release large amounts of greenhouse gases into the atmosphere and trap heat, leading to global warming. Climate change has significant impacts on the environment, including rising sea levels, more frequent and severe weather events, and changes in ecosystems and wildlife populations.
