Successful prediction is the ultimate test whether science is in accordance with reality.
If it were correct that the Sun's forcing of climate was negligible in the second half of the 20th century and will be so in the future, it should have been impossible in recent decades to predict climatic phenomena exclusively on the basis of cycles of solar activity. Repeated forecast experiments show, however, that the contrary is true. Figure 24 of this paper shows that all maxima and minima in global temperature anomalies observed by balloon sondes after 1958 are explained by the solar torque cycle. This is no mere theoretical relationship. It should be noted that all these skillful forecasts fall at the recent decade that should show no traceable solar effect.
