Sea levels along almost the entire Indian coast are rising faster than the global average, according to the World Meteorological Organization’s (WMO) State of the Global Climate in 2021 report released May 18, 2022. Globally, the rate of sea-level rise was 4.5 millimetre per year between 2013 and 2021. This was more than twice the rate between 1993 and 2002. The major reason for the increase in sea levels is the accelerated loss of ice from the ice sheets in the Arctic and Antarctic regions. The Indian Ocean region has previously been described as the fastest warming ocean in the world, with an increase in temperature of one degree Celsius as against the global average of 0.7°C between 1951 and 2015. Ocean heat content had already reached record levels in 2021 globally.
