The 1970 SCEP report
or, "Man's impact on the global environment", "Assessment and
recommendations for action". This was the report of a month-long
workshop sponsored by MIT.
Its unexciting (and, judging from google, mostly unreferenced).
About the only things I want to note here is that it
increasing CO2 likely to increase global (surface) temperature
(guessing a 2 oC increase for doubling CO2 [p 12]). It notes that this
estimate is "very uncertain" but the best then available.
- doesn't consider Milankovitch-type cooling at all (the nearest it comes
to this appears to be section 4.1 [p 77] where it notes that climate
has changes in the past, and that Man might now be forcing his way with or
against the natural tide of cliamtic change).
- does consider particulates (/aerosols) but says that "in general
it is not possible to determine whether such changes would result in
a warming or cooling of the earths surface." [p13].
So there you have it: whatever interest there was in "global cooling"
wasn't obvious in 1970.
