Well, SLCPS have a lifetime of only a few days-few years, so I wouldn't say decades is exactly correct unless it's listed in your tutorials.
They give a warm influence on the climate.
Short-lived climate pollutants (SLCPs) persist in the atmosphere for a few days to a few Decades, and they make the climate Warm.
So the answer to this is warm because of the pollution in the air which can cause global warming.
Hope this helped :) Have a great day
