Fun fact: many millennia ago the largest desert on earth (Sahara) used to be a lush prairie and heavily forested.

Lesson: The earth is a massive set of interconnected dynamical systems. Climate is always changing and has changed much more drastically in the past - both in terms of warming and cooling.

Prescribing these inevitable climatic changes to any specific factor is an exercise in insanity. Co2 especially as this is a trace gas and is well documented to lag or be wholly uncorrelated with average atmospheric temperate.

Looking at co2 and attempting to infer global climate trajectories is like watching a single pixel on a 60 inch TV and pretending to understand the movie.
