It was in the paper "Climatic Change: Are We on the Brink of a Pronounced Global Warming?" in the journal Science in 1975.

When I was a US Navy weather guy, 1858 to 1968, I read some research papers that suggested that while some of the data suggested a cooling trend, an ever increasing CO2 load of industrially generated Carbon Dioxide at that point seemed to have trumped the general trend. Of course the data was thin either way until after the Geophysical Year (1958) collect a vast amount of climate data.
Check out the Aug. 2014 Scientific American...Sickness in the Artic concerning the evidence of how various pathogens are moving north. Pity the Artic Musk oxen!
A series of papers in 1965-68, actually used the words 'global warming' in several places, a situation that could lead to 'climate change'. Not too many people paid attention as the factors that might produce a 'cooling trend' were found to far more complex then first thought.
At this point it's obvious that the 'warming trend' has effected the oceans and the permanent ice fields far more than the atmosphere as heat seeks out colder venues. The direct and indirect data is overwhelming. How bad and how soon is still a guess, but the fact that it's happening is beyond doubt.
I don't know but i first heard of it from the movie Soylent Green.

Both Terms Have Long Been Used
The argument "they changed the name" suggests that the term 'global warming' was previously the norm, and the widespread use of the term 'climate change' is now. However, this is simply untrue. For example, a seminal climate science work is Gilbert Plass' 1956 study 'The Carbon Dioxide Theory of Climatic Change' (which coincidentally estimated the climate sensitivity to a doubling of atmospheric carbon dioxide at 3.6°C, not far off from today's widely accepted most likely value of 3°C). Barrett and Gast published a letter in Science in 1971 entitled simply 'Climate Change'. The journal 'Climatic Change' was created in 1977 (and is still published today). The IPCC was formed in 1988, and of course the 'CC' is 'climate change', not 'global warming'. There are many, many other examples of the use of the term 'climate change' many decades ago. There is nothing new whatsoever about the usage of the term.

I dunno. but Fourier, in the 1820’s theorized that the atmosphere traps heat, or else the Earth would be colder.
Tyndall, in mid 1800’s theorized, CO2 blocked heat transfer, based on lab work.
Arrhenius in 1896: predicted 5-6 oC increase in temp. due to doubling of CO2.
