The connection between atmospheric CO2 and warming was actually identified as early as around the year 1900.

I wasn't around then to have a sense of the broad social awareness of things, but I've gotten the impression that the science was fairly obvious before the 1970s.

I assume that the year 1900 "identification" you refer to is the work from Svante Arrhenius, which was later disproved.

To me it reads of the kind of Rachel Carson types of environmental damages that were getting much more attention at that time. (Acid rain, pollutants, runoff, etc)

If they had anticipated CO2 (and yes, I agree it was known by some well before this time), they should have / would have made it much more specific to include that kind of slow, "who is responsible" kind of harm.
