Sea levels rising faster, Indian cities at high flood risk: IPCC
New Delhi: Four Indian coastal cities — Kolkata, Mumbai, Surat and Chennai — will be severely threatened due to sea level rise while several others in the north India will be exposed to acute water crisis due to melting of Himalayan glaciers by the end of the century, a UN body on climate change hinted on Wednesday.
Sea levels, rising faster than ever before, are on course to rise one metre higher due to melting of ice in the business-as-usual scenario by 2100, severely affecting over 1.4 billion people globally, a special report on “oceans and cryosphere” released by the Intergovernmental Panel on Climate Change (IPCC) warned on Wednesday.
Four Indian cities are among 45 such coastal port cities globally where even an increase of sea level by 50cm will lead to flooding. In fact, the extreme sea level events that used to happen once a century in the past will occur every year by mid-century in many regions, increasing risks for many low-lying coastal cities and small islands.
