Andhras long coastline exposes Vizag, two other key port cities to climate impact #IndiaNEWS #Andhra Pradesh
Visakhapatnam: Rising sea levels, increasing ocean temperature, monsoon extremes and cyclones are the impact of climate change for the coastal areas of Andhra Pradesh.
While the long coastal line of the state in general faces the climate change issues, cities like Visakhapatnam, Kakinada and Machilipatnam are particularly vulnerable.
According to scientists, abnormality of the cyclones is the result of global warming and climate change. Visakhapatnam, the biggest city in the state and the proposed state capital, has experienced eight severe cyclonic storms since 2014.
Vizag, as the port city is also known, was battered by very severe cyclonic storm Hudhud on October 12, 2014. For the first time in modern history, the city witnessed an unparalleled natural calamity.
With wind speed of 165 kmph during landfall, Hudhud caused widespread devastation in the city and other parts of north coastal Andhra killing 60 people and uprooting thousands of trees, electricity poles and destroying the civic infrastructure. It took weeks for normalcy to be restored in the city.
Experts are of the view that huge disparity in the temperature of the land and the ocean may lead to formation of many cyclonic storms, which will have the potential to develop into very severe cyclonic storms. Strong winds and high rainfall will lead to an increase in the sea level.
The states long coastline faces the double threat of floods and rising sea levels due to climate change. The vulnerability was again evident in May 2020 when cyclone Amphan, strongest storm recorded in decades in Bay of Bengal, hit the coast forcing several million to evacuate
Experts say global warming has rendered monsoon erratic and extreme and is giving way to high intensity thunderstorms which will increase the possibility of flash floods and landslides. Moreover, during thunderstorms, the rainfall is quick and high and this also increases the sea levels.
Melting of the glaciers due to global warming is also causing the sea level to rise. Different factors are likely to lead to flooding of the coastal cities and regions
According to SSVS Ramakrishna, former head of the department of oceanography and meteorology, Andhra University, global warming has resulted in a rise in ocean temperatures, the temperature in the Indian ocean has risen much quicker than expected.
As per the report of the UNs Intergovernmental Panel on Climate Change (IPCC), Visakhapatnam is one among six Indian cities that could be exposed to coastal flooding if the sea levels rise by 50 cm due to global warming.
According to the report, the city will be under 3 feet of sea water due to rising sea levels by the end of the century.
