Global warming failed, because the globe isn’t warming fast enough for anyone to notice. Climate change is a preferable term, because it has no metrics and can be applied to any weather pattern. No one can say that the climate isn’t changing, because it changes constantly. No actual science or link to CO2 is necessary.

Scoundrels have been using “climate change” to control the masses for as long as mankind has organized into groups.
