10. Roxy Mathew Koll, a Climate
scientist at the Indian
Institute of Tropical
Meteorology, believes that
climate change also has a big
impact on coastal regions.
In Visakhapatnam, around 206
buildings and 9 km of the road
network are likely to be
inundated due to potential
coastline changes by 2050.
Due to rise in sea level in

IMPACT ON
VISAKHAPATNAM
“Hud hud was an eye-opener, as it
was a dry tropical cyclone, a
phenomenon associated with
global warming and climate
change”, said Prof. SSVS
Ramakrishna of the Department of
Oceanography and Meteorology,
Andhra University.

12. “As the climate warms and
ice melts, sea levels
rise”, said by
the scientists of the
National Centre for Polar
and Ocean Research.
Since 1990, according to
the model in
Visakhapatnam , there has
been a rise of approx. …
14 cm in the sea level in
the area.
