The IPCC definition of "climate change" as a detectable change in the statistics of weather (and outcome metric) has been increasingly rejected in favor of "climate change" defined as a causal actor that changes weather
These definitions are 100% incompatible

17 years ago I wrote about how the different definitions of "climate change" used by the FCCC and IPCC was problematic for connecting science and policy

I hypothesize that today "climate change" is used often today as shorthand to refer to "emissions" (GHGs or CO2)
So instead of:
emissions-->alter weather statistics over 30 yrs+
we get:
climate change-->alters weather

One casualty of our changing conception of "climate change" has been the notion of "climate variability"
