A set of well-mixed greenhouse gases with long atmospheric lifetimes. This set of compounds includes 2) carbon dioxide (CO and 2 O) nitrous oxide (N, together with some halogenated compounds. They have a warming effect on climate. These compounds accumulate in the atmosphere at decadal to centennial time scales, and their effect on climate hence persists for decades to centuries after their emission. On time scales of decades to a century, already emitted emissions of long-lived climate forcers can only be abated by greenhouse gas removal. (English)
