Arctic melting Glaciers to speed up global warming
Researchers from the National Institute of Oceanography (NIO), who returned from the Arctic assignment recently, have said the trend is a serious concern as it may fuel global warming.
Panaji: The Arctic would drastically
reduce its capability to act as a "global carbon sink" in the
future due to the quickly receding glacier cover, according to
the Indian mission on the region.
Researchers from the National Institute of
Oceanography (NIO), who returned from the Arctic assignment
recently, have said the trend is a serious concern as it may
fuel global warming.
NIO`s senior scientist S Prasannakumar said that
Arctic seas and land together accounts for about 25 per cent
of the world`s carbon sink.
"The melting of glaciers and Ice cover from Fjords
would mean a less efficient carbon sink that would end up in
faster global warming," he said.
The five-member NIO team, which was in the icy
continent in the last week of May, have chosen Kongsforden
Fjord as the sample water body which would now be monitored
for next decade.
Prassanakumar said that Kongsforden Fjord is situated
just 100 metres away from Himadri, Indian research station on
Arctic continent. Fjord is a long inlet with steep sides
created in a valley carved by glacier activity.
The Fjord is being studied for physical, chemical and
biological parameter study of Kongsforden Fjord located in the
Scientists have raised concerns on melting glacier
as the phenomenon has been reported more rapid since last half
Dr Prasannakumar said, "In simple terms, this means
that Arctic will loose its ability to absorb large amount of
carbon dioxide thereby accelerating the global warming
The other worries that melting glaciers would enhance
sea water are also on the agenda of researchers.
"It is estimated that Arctic region would be ice free
in next 30-40 years time," the researcher said, adding `global
carbon cycle will change with the melting of Arctic glaciers.`
