It's the anthropogenically enhanced greenhouse effect. The normal (unenhanced) greenhouse effect warms the planet and keeps it inhabitable. It does this by impeding the cooling in the same way as a blanket "warms" you.

It does not heat the planet. There is only one source of heat - the Sun - and that has not changed.

The anthropogenically enhanced greenhouse effect adds more warming.

So, I agree "global warming" is a much more accurate term.

However, global warming manifests itself as an insidious long-term trend on a multidecadal timescale.

Attribution of individual spectacular weather events to global warming is over-simplistic. (And the IPCC (WG1) are very cautious about doing so.) For example, the current drought/heat wave in the SW USA is caused by the La Nina. https://www.latimes.com/california/story/2020-09-11/what-does-la-nina-mean-for-californias-drought

But global warming might have made it slightly worse by maybe a degree (or two in Fahrenheit).
