<human>:  What are the causes of climate change?
<bot>: The most significant cause of climate change is the increasing emissions of greenhouse gases into the atmosphere, primarily from the burning of fossil fuels such as coal, oil, and gas. Other contributors to climate change include land-use change, which leads to deforestation and changes in land cover, as well as industrial processes like cement production and certain aerosol emissions. Natural forces, like changes in the sun’s intensity, volcanic eruptions, and variations in ocean currents, also play a role in the global climate system.
