Carbon dioxide is the main cause of human-induced climate change. It has been emitted in vast quantities from the burning of fossil fuels and it is a very long-lived gas, which means it continues to affect the climate system during its long residence time in the atmosphere.
The external climate forcing processes and the internal climate forcing processes except the man-made processes are grouped together as natural causes of climate change while the man-made processes are the anthropogenic or human causes of climate change. The natural causes are believed to even out eventually and are not considered to be responsible for climate change.
