Development
The first version of CCSM was created in 1983 as the Community Climate Model. Over the next two decades it was steadily improved and was renamed CCSM after the CSM (Climate System Model) components were introduced in May 1996. In June 2004, NCAR released the third version of CCSM, which included new versions of all of the component models. In 2007, this new version of CCSM (commonly given the acronym CCSM3, or the abbreviation NCCCSM) was used in the IPCC Fourth Assessment Report, alongside many other GCMs from different countries and institutions. In May 2010, NCAR released CCSM version 4. On June 25, 2010, NCAR released the successor to CCSM, called the Community Earth System Model (CESM), version 1.0, as a unified code release that includes the capability to run CCSM4.

“And then ... he flung open the door of my compartment, and ushered in “Ma young and lovely lady!” I muttered to myself with some bitterness. “And this is, of course, the opening scene of Vol. I. She is the Heroine. And I am one of those subordinate characters that only turn up when needed for the development of her destiny, and whose final appearance is outside the church, waiting to greet the Happy Pair!””
—Lewis Carroll [Charles Lutwidge Dodgson] (1832–1898)
