Short-lived climate pollutants (SLCPs) have a relatively short lifetime in the atmosphere – a few days to a few decades – and a powerful warming influence on climate. The main short-lived climate pollutants are black carbon, methane and tropospheric ozone, which are the most important contributors to the human enhancement of the global ...
