"The misuse of scenarios in climate research means that much of what we think we know about our collective climate future may be incomplete, myopic or even misleading or wrong, and as such, “uncomfortable knowledge”" https://twitter.com/RogerPielkeJr/status/1252615906573692928">https://twitter.com/RogerPiel...

"scenario misuse in climate science offers one of the most significant and underappreciated examples of the current crisis in scientific integrity"

Each refers to alternative runs of an integrated assessment model & neither necessarily shows consistency with the real world, present or future.
Confusion of models & the real world is endemic.
