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.

The problem is, to reduce enough green house gases to effect the temp
of the earth we'd have to cover 50% of the oceans with a material that
would prevent moisture from getting into the atmosphere. Besides, why
do I care that the earth doesn't (and never has) maintained a
continuous temperature? Who am I to tell the earth what it is or is
not suppose to do?
