The CO2 that is
currently at 380ppm but has been at 3000ppm for most of the history of
life on the planet?

During the 3.5 billion years of Earth's existence its atmosphere did
not contain appreciable amounts of life sustaining oxygen until ~500
million years ago. So I don't see the relevance of that statement.

Regardless, it would seem that the climate is warming now, and it
would behoove us ALL to do what we can to reduce the speed with which
that is occurring.

Funny how the "warming" (0.5 degrees C on average at the surface, but
no measureable change at higher altitudes) seems to be tracking the
average solar output...

CO2 levels have been much higher for most of the history of life, see
