When, why, and how did "Global Warming" officially become "Climate Change" ?

Back when we first started studying our effects on the climate, the process was actually called "inadvertent climate modification" in the field. The term "climate change" and "global warming" came around the same time during the 80s. The latter was used to describe the surface heating effects and the former used to describe the whole process in general. In 88', James Hansen, a NASA climate scientist, gave his testimony on climate change at a Senate hearing. He used the term "global warming" and it caught on. The climate discussion was just about to gain traction when the Gulf War happened and took the spotlight. It wasn't until after 9/11 that people really started talking about it again.

This is a pretty good study on the use of the terms and how it's evolved over time: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4587979/
