Coastal states in Mumbai, Kolkata & four other Indian cities will be underwater by 2030 finds report

Firstpost  

Maps show parts of Mumbai, almost the entirety of Navi Mumbai, the coastal areas of Sunderbans, and the surrounding areas of West Bengal’s capital, Kolkata, along with Cuttack in Odisha, may be below tide-level in 2030. Cycles of floods caused by heavy bursts of rainfall and a rise in droughts due to increased evaporation, is potentially what India’s climate future will look like as the world barrels towards breaching the 1.5 degree Celsius ceiling for global warming by 2040, a UN report has said. On its new Coastal Risk Screening Tool, where the projections show which cities are at risk to be below sea levels up to 2150, even the closest depiction of 2030 paints a dangerous picture for some Indian cities - especially in the states of Maharashtra, Gujarat, Kerala and West Bengal. Here’s a closer look at the areas which will be below tide level by 2030: This map shows how parts of Mumbai, almost the entirety of Navi Mumbai, the coastal areas of Sunderbans, and the surrounding areas of West Bengal’s capital, Kolkata, along with Cuttack in Odisha, may be below tide-level in 2030.
