"For a Civilization so widely distributed, no uniform ending need be postulated. Circumstances which affected it in the sub-montane lands of the central Indus may well have differed widely from those which it encountered south or east of the Indian Desert and in the watery coastlands of the Rann of Kutch. Later archaeologists often disagreed, finding little or no evidence for a climate significantly different in Harappan times from today’s. And the evidence at present available indicates that such indeed was the case."
