Abstract

The mean temperature for the Northern Hemisphere had a warming trend from 1890 to 1950 and a cooling trend since 1950. The eastern and central United States had colder temperatures in 1961–1970 than in 1931–1960. The temperature changes were associated with an adjustment of hemispheric circulation from more frequent zonal flow between 1900 to 1950 to more frequent meridional flow since 1950. Regional variations in magnitude and direction of the change were largely related to position in relation to the upper air westerly wave pattern. Time series of individual circulation indices tend to resemble the step function model of climatic change. [ABSTRACT FROM AUTHOR]

2. Between Ice Ages?

Abstract

This article presents information on the book "Climatic Change: Evidence, Causes and Effects," edited by Harlow Shapley. Most scientists are now agreed that the climate is again changing over very great areas of the world. This process has been in operation for at least 65 years and perhaps a century, and has been accentuated in the past two decades. This change in climate may be a mere temporary swing of a few decades or centuries, an insignificant period from the viewpoint of the geologists. The change may, again, mark the end of what Shapley calls the Little Ice Age, which began in certain regions about the time of Britain's first Queen Elizabeth, and has lasted until the present.
