Holding concentrations or temperature (more remotely) to a particular target therefore means limiting cumulative emissions of, say, carbon over time... a limited amount of time if we are talking about an iterative approach, and over a long period of time if we are talking about reducing the likelihood of some very nasty consequences well after we (but not our grandchildren — if we are lucky enough to have some) are gone.

If thunderstorms start to become more frequent as the Earth warms, the consequences could include increased skin cancers, crop damage and other nasty consequences. (climatecentral.org)
