The third edition of the CO2 Newsletter, published bi-monthly by American geologist William N. Barbat between 1979 and 1982 is live. You can download a pdf and see the full text here.
The eight page issue has a front page story on the Greenland ice sheet and sea level rise (and a full page analysis on page 3 “Glacial icemelt? How soon? How Fast?”
There’s also an editorial, feedback from readers, excerpts from recent reports and a concluding article “the cost of halting the CO2 buildup.”
It remains heart-breaking, of course. Barbat’s editorial begins
“The new decade begins on an optimistic note as the CO2 greenhouse problem is beginning to receive deserved attention in scientific, political, and economic institutions. Also this particular environmental issue may unite former adversaries in a common effort. “

Barbat had switched on to environmental problems over a decade earlier, including carbon dioxide build-up. In 1979 he started the Newsletter. It was intended to fill a
“communications gap by capsulizing both the published and unpublished reports on the CO2 problem which are deemed important. This newsletter will also publish original material. invited articles. and letters of inquiry, fact and opinion.”
Each 8 page Newsletter had a lead story, an editorial, excerpts of recent documents (reports, newspaper articles, scientific abstracts, testimony by scientists to Congressional hearings) and deeply researched and argued articles by Barbat about a range of issues. Most issues had feedback from readers.
