As Mumbai once again gets flooded due to heavy rains, Maharashtra environment minister Aaditya Thackeray on Wednesday said climate change has become a real thing and stressed on undertaking mitigation measures as part of a larger action plan to deal with the phenomenon.

He visited the headquarters of the BMC, controlled by his party Shiv Sena, to take stock of the situation after overnight torrential rains flooded parts of Mumbai and disrupted rail and road traffic on Wednesday in what has become an annual occurrence during the monsoon.
