Carbon dioxide is the main cause of human-induced climate change. It is a very long-lived gas which means levels of carbon dioxide build up in the atmosphere with on-going human emissions. Stopping climate change, that is, stabilizing global average temperature can only be brought about by reducing global emissions of carbon dioxide from human fossil fuel combustion and industrial processes to near-zero levels. Climate models have shown that to limit global warming to 2 °C, this ‘zeroing’ of human emissions needs to be accomplished by around the middle of the century. This indicates how difficult the challenge is.</font>
