No, they changed it because it’s a more appropriate term for the phenomenon. While global average temperatures are rising, the net effect of having more energy in the system is change (broadly speaking for the negative).

Using ‘global warming’ as a term gives misinformation spreaders an easy tool to undermine the concept on a cold year/winter. ‘Climate change’ cannot be undermined in the same way, because anyone can plainly see that the climate ain’t exactly what it used to be.
