Karnataka’s Mangalore might be at higher risk of drowning. As the sea rising level is triggered by glacial melting in the cities such as Mumbai and New York. This data is released by NASA study.
Ice sheets will impact sea levels in local coastal cities.
NASA scientists developed a new tool. The new tool is called Gradient fingerprint mapping. The short name is GFM. It allows the planners and the public to forecast that.
A member of NASA team said that people can desperately understand how these are complicated global. With the help of GFM the scientists can see the impact on their city and even people can see the impact.
Already tool was tested:
This new tool was already applied by the researchers of California’s NASA Jet Propulsion Laboratory to 293 port cities which include Mangalore, Maharashtra, and Kakinada in India.
Almost 75 percent of the World’s fresh water is stored in the glaciers and mostly in Greenland and the Antarctica. Melting the ice sheets on both is a great contributor to raise the sea level.
The new tool measures how delicate local sea level rise is to the change in the thickness of the ice sheets. It is that captures how much ice the ice sheet has lost.
The delicateness or the sensitivity is measured in the terms of Gradient. The dH or dS and it is classified into four bands, they are -4 to -2, -2 to 0, 0 to 2, 2 to 4.
The sensitivity is too high for Mangalore to change the thickness of ice in almost all the regions of Greenland and the Antarctica ice sheet. It is more sensitive to the changes in the western part of Antarctica ice sheet and the southern area of the Greenland ice sheet.
The northern and the eastern parts of the Greenland are more dangerous for melting in New York. The changes in the north-west part ice sheet in Greenland, raise sea level of the local coastal area of London might be impacted.
