Heat waves will turn into “extreme heat waves” in the subcontinent, aberrantly high monsoon rainfall will give us intimations of the end foretold in myth—via pluvial floods. Snowcaps in the Himalayas and Hindu Kush will thaw rapidly—a vicious chain again, deluge followed by aridity. Even in the lowest emission scenarios, because of the warming of the oceans as well as the melting of ice sheets and glaciers, global mean sea levels will continue to rise over the 21st century. India’s 7,500-km-plus coastline is specially vulnerable. Across six Indian port cities—Chennai, Kochi, Calcutta, Mumbai, Surat and Visakhapatnam—28.6 million people could be exposed to coastal flooding if the sea waters swell by even 50 centimetres. Assets worth about $4 trillion will be exposed to flooding. In fact, a NASA projection based on the IPCC report says an entire array of coastal Indian cities will be under 2.7 feet of water within 80 years. From Bhavnagar, in Gujarat’s protruding lower jaw, down to Bombay, Mangalore, Kochi, and back up on the east with Chennai, Vizag, Paradip, all the way to Khidirpur’s old docks, and every inch of lowland in between: a whole peninsular ingress. Not counting Lakshadweep, where they’re presently planning airports and ‘ring roads’ on 5 sq km islands.
