I was recently in Mumbai as the monsoon arrived there on its march towards Delhi and the northern plains. Mumbai has suffered from its fair share of flooding in recent years. In July 2005, an incredible 944mm fell over the course of a 24-hour period. There is of course a persistent fear that such a deluge might occur again. But I witnessed only a stoical sense of business-as-usual when the first drops of rain fell and the cruel summer sun at last fell behind dark clouds.
