NASA scientists will study how global warming is
melting Greenland’s ice. Specifically, Scientists would study whether melting
is being caused more by warm air or warm seawater. The project is known as
Oceans Melting Greenland (OMG).
To study the melting of ice, NASA scientists
will fly over Greenland for 5 years in a Douglas DC-3 aircraft.
A 2019 study looked at 28 glaciers in Greenland
with long-term data and found that nearly all are melting. Further, a NASA
satellite found that Greenland’s ice sheet lost about 255 billion metric tons a
year between 2003 and 2016.
According to scientists, along with warm air,
warm sea water might play a crucial role in melting of ice. This is because warm,
salty water weakens coastal glaciers from below and causes them to break way
and finally melt.
