On October 29, 2019, the journal Nature published an important paper identifying the dangers climate change poses specifically to Mumbai and other coastal cities.

The research, carried by many newspapers including The Indian Express, indicates that anthropogenic climate change will inundate significant sections of Mumbai by 2050. Unless the city takes significant action in the next three decades, the sea will reclaim much of the landfill that the city has been built on. As per this study, Mumbai in 2050 will look a lot like Mumbai in 1700, unless the city makes serious efforts to adapt to climate change.

What do the studies say?

Recent studies, published by the Intergovernmental Panel on Climate Change (IPCC) and in Nature by Lu and Flavelle in October 2019 indicate that its effects are more intensive than earlier models predicted.

For example, sea levels are rising significantly faster than were previously estimated. The Special Report on the Ocean and Cryosphere in a Changing Climate, published last month by the IPCC, indicates that sea levels are significantly higher than were originally anticipated, and as such will have significant impacts on cities like Mumbai.
