     However, if we stopped emitting greenhouse gases today, the rise in global temperatures would begin to flatten within a few years.

    Temperatures would then plateau but remain well-elevated for many, many centuries.

    There is a time lag between what we do and when we feel it, but that lag is less than a decade.
