One of the earliest climate-related documents in the CIA library is a 1958 Joint Services Publications report on Soviet analyses of so-called global “heat balances.” The report mostly consists of hundreds of footnotes referencing the work of Soviet climatologists who seemed way ahead on the issue. Until the 1990s, most of the CIA research entries for “climate change” and “global warming” are simply translations of Soviet science journals.
