Short-lived climate forcers are a set of chemically and physically reactive compounds which affect climate and are, in most cases, also air pollutants.

Their atmospheric lifetime is typically shorter than two decades and sometimes only persist in the atmosphere from a few hours to a couple of months.

SLCFs include aerosols such as hydrofluorcarbons, and chemically reactive gases such as methane, ozone, carbon monoxide, sulphur dioxide and ammonia.

They can have either a cooling or warming effect on climate, and they also affect precipitation and other climate variables.

While SLCFs account for far less of the total volume of annual greenhouse gas emissions than carbon dioxide, they nonetheless cause around 40% percent of the total warming caused by the greenhouse effect.
