Residence time refers to the amount of time something spends in a particular place or system. It is essentially how long something stays or remains in a specific location or environment. Full definition
Based on CO2's long residence time in the atmosphere, it dominates long - term committed forcing. (dotearth.blogs.nytimes.com)
The low pressure vapour phase coupled with the short residence times mean the ingredients do not see excess temperatures whilst processing. (steaminfusion.oalgroup.com)
There is also the difference in atmospheric residence time or the fact you'd have to keep increasing aerosols as CO2 increases, and at larger rates. (realclimate.org)
