Line 1:
'''Climate commitment''' describes the fact that climate reacts with a delay to influencing factors ("climate forcings") such as the presence of [[greenhouse gas]]es. '''Climate commitment studies''' attempt to assess the amount of future warming that is "committed" under the assumption of some constant level of forcings. The "constant level" often used for illustrative purposes is CO2 doubling or quadrupling; or the present level of forcing.

Line 11 ⟶ 10:
* "[[transient]]" climate prediction runs in which a full ocean is used and the climate is out of balance.
Note that "commitment" can apply to variables other than temperature: because of the long mixing time for heat into the deep ocean, a given surface warming "commits" to centuries of sea level rise from thermal expansion of the ocean. Also once a certain threshold is crossed, it is likely that a slow melting of the Greenland ice sheet will commit us to a sea level rise of 5m over
