Temperature data from 1956 to 2016 at 927 weather stations of the Northern Hemisphere is studied focusing on the emergent properties of the climate system. We introduce a measure to estimate climate variability. The measure is calculated as the correlation coefficient of mean-positive and mean-negative temperature rates which, respectively, are connected with the influent and effluent energies averaged over the observation interval. It has been found that the mean-positive and mean-negative rates are balanced and have a high degree of association with each other. A hypothesis about the essence of geospheric balancing is proposed, and estimates for it are obtained. Changes in the measure are calculated in the period from 1999 to 2016. The thus discovered properties open a way for comparisons of the observed and emergent characteristics that may foster the development of ideas related to climate. This approach is aimed at monitoring climate variability and paving a promising path to this goal.
