What a load of bull****. AGW was quite well established as a threat in the
1970's - in the free capitalist west.

T.
Evidence??

Atmospheric chemistry sciences were involved in the ozone hole hoax at that
time. The carbon cycle people were not concerned at all with dramatic
climatic effects.

Well it's certainly true that as far as environmental concerns go, the
top two priorities back then in the 70s were acid rain and the ozone
depletion.
These were really pressing problems back then, acid rain was
threatening to wipe out whole aquatic biotopes. They were also in
comparision with the CO2 issue simple to solve.

Both were minor issues in the 1970s. It was in the 1980s that they
hit the front pages with the Antarctic ozone hole, and lake acidification
and forest die off in the northeastern US.

It is correct that the discovery that there really was a huge ozone hole
was back the 80s. However I recall back in the early 70s an atmospheric
scientist telling me his concern that CFCs could damage the ozone layer.

At least that's how I recall it. Spray can ban of CFCs, true, was done in
the 1970s out of ozone concerns, but that was a much more sedate affair
than the 1980s and Montreal Protocol.

Any refs to the concerns in the 1970s about acid rain?


Wikipedia is your friend:
"Though acidic rain was discovered in 1852, it wasn't until the late
1960s that scientists began widely observing and studying the
phenomenon. The term "acid rain" was generated in 1972.[5] Canadian
Harold Harvey was among the first to research a "dead" lake. Public
awareness of acid rain in the U.S increased in the 1970s after the New
York Times promulgated reports from the Hubbard Brook Experimental
Forest in New Hampshire of the myriad deleterious environmental effects
demonstrated to result from it.[6][7]"
