<human>:  Help me understand the causes of climate change.
<bot>: The primary cause of climate change is increasing levels of greenhouse gases like carbon dioxide in Earth's atmosphere. These gases trap heat, leading to a gradual increase in global temperatures. Other climate change drivers include land use changes such as deforestation, emissions from burning fossil fuels, and livestock farming. All of these activities have contributed to a rise in average global temperatures, which is leading to more extreme weather, rises in sea levels, and changes in global ecosystems.
