Causes of climate change

Carbon dioxide is the main cause of humaninduced climate change. It stays in the atmosphere for a very long time. Other greenhouse gases, such as nitrous oxide, stay in the atmosphere for a long time. Other substances only produce shortterm effects. Not all substances produce warming. Some, like certain aerosols, can produce cooling.
