"One of the study’s most important insights is that the problem is not declining average rainfall, but rising #ClimateVariability.
Statistical tests show little difference in average drought conditions between the early and recent periods. However, when the researchers examine extremes, a clear shift emerges. Wet periods have become wetter, but dry periods have also become drier. The gap between these extremes has widened sharply, especially over longer time scales."
