Early Climate Change Study

Reading the following excerpt from a weather study, would lead one to think this is from a typical "Global Warming" scare story from some current day magazine or newspaper. Instead, this is from 1933, when much of the globe was going through a major warming cycle. This cycle may have lead to the disastrous "dust bowl" of the 30's. In less than 10 years, the earth would move into a cooling cycle that lasted through the 70's.

The present wide-spread and persistent tendency toward
warmer weather, and especially the recent long
series of mild winters, has attracted considerable public
interest; so much so that frequently the question is asked
“Is our climate changing? ”

All of these confirm the general statment that we are in the midst of a period of abnormal warmth, which has come on more or
less gradually for many years. An example of this
auxiliary evidence is shown in figure 12, in which the
general trend of the number of days with freezing weather
in fall and in spring at Washingt,on, D.C., is charted for a
period of 6O years (data in table 2). It will be noted
that for the 20 years ending with 1892 there was for the
spring months (after February) a total of 354 days with
minimum temperature 32' or lower, and for the 20 years,
ending with 1933, this had dropped to 237 days.

Here is a link to the entire study...
