Here you go. Took me all of 30 seconds.

Ooops, this is a report about the report. Trouble is, of course, that 1975 is quite a while ago. Computers were not nearly as widespread as they are now. So...
No... took me two minutes
Full text of Understanding climatic change
PS: As usual SSDD, you're wrong.
First, contrary to rock's claim, that paper was never published in the PNAS...it is the program for action described in the CIA file...second, you clearly have never read the paper...there are 12 mentions of warming and 23 mentions of cooling in the paper...and the paper represents a clear and present danger of a major cooling of the earth in the near future...
A striking feature of the instrumental record is the behavior of temperature worldwide. As shown by Mitchell (1970), the average surfaceair temperature in the northern hemisphere increased from the 1880's until about 1940 and has been decreasing thereafter (see Figure A. 6, Appendix A). Starr and Oort (1973) have reported that, during the
period 1958-1963, the hemisphere's (mass-weighted) mean temperature decreased by about 0.6 °C. In that period the polar and subtropicalarid regions experienced the greatest cooling. The cause of this variation is not known, although clearly this trend cannot continue indefinitely.
During the global warming of the first part of this century, for example, the average length of the growing season in England (as measured by the duration of temperatures above 42 °F) increased by two to three weeks and during the more recent cooling trend since the 1940's has undergone a comparable shortening
The well-documented warming trend of global climate beginning in the 1880's and continuing until the
1940's is a continuation of the warming trend that terminated the Little Ice Age. Since the 1940's, mean temperatures have declined and are now nearly halfway back to the 1880 levels.
The onset of this climatic decline could be several thousand years in the future, although there is a finite probability that a serious worldwide cooling could befall the earth within the next hundred years.
Seems that you can't read a paper any better than you can read a graph....the idea that you are an engineer is patently ludicrous....the thought makes me laugh out loud. The paper clearly is warning of a rapidly approaching cooling period. When one considers the fact that mentions of the possibility of warming are the minority when compared to mentions of cooling, the idea that the paper could be construed to be warning of anything other than an approaching cooling period is grasping straws by the warmer crowd.
The consensus of the day was clearly in favor of an approaching cooling period....the meme turned to warming when the cooling didn't happen...just as the meme turned to climate change when the predicted warming of later years didn't happen. Climate science eventually is going to have to stop simply predicting what is happening and then changing predictions with the weather and actually do some real science.
