Sea Level Along Indian Coast Rose By 8.5 Cm In Last 50 Years: Environment Minister

New Delhi: Sea stage alongside the Indian coast rose by 8.5 cm within the final 5 many years, Union Minister Babul Supriyo mentioned within the Rajya Sabha on Tuesday.

Responding to a query on whether or not a number of cities will probably be submerged as temperatures are rising attributable to world warming, the minister of state (MoS) for surroundings mentioned that the speed of improve of sea stage attributable to local weather change can’t be attributed with certainty.

“On an average, the sea level along the Indian coast is considered to be rising at about 1.70 mm/year meaning thereby that during the past 50 years, the sea level along the Indian coasts has risen by 8.5 cm,” he mentioned within the higher home of Parliament.

“Further, satellite altimetry and model simulations showed that the North Indian Ocean (NIO) also exhibits decadal variability. During the last decade (2003-2013) it experienced sea level rise at a rate of 6.1 mm/year,” added Supriyo in a written response.

The minister additional mentioned that the rising sea ranges can exacerbate the coastal inundation alongside the low mendacity areas throughout excessive occasions similar to tsunami, storm surge, coastal flooding and coastal erosion.

“However, the coastal areas that might get inundated due to the rising sea level need to be evaluated based on their elevation above mean sea level. Since no long term data on land subsidence or emergence are available for these locations, the rate of increase of sea level due to climate change cannot be attributed with certainty,” he mentioned.

“For example, the higher rate of sea level increase at Diamond Harbour is also due to the larger land subsidence happening there. The same may apply to Kandla, Haldia and Port Blair as well,” Supriyo advised the Rajya Sabha.

Lately, a report of the UN’s Inter Governmental Panel on Local weather Change (IPCC) had warned that world sea ranges are set to rise by a minimum of 1m by 2100 if carbon emissions go unchecked, submerging tons of of cities, together with Mumbai and Kolkata, and in some instances whole nations.
