Tides becoming danger for Glaciers, Sea Levels could Increase More than Earlier Projections, Findings of New Study

Many countries are facing difficulties due to global warming. The melting of glaciers could cause sea levels to rise more than previously estimated. Due to this, there is also a possibility that a large part of the landmass of some countries may sink into the sea. Maldives is also included in such countries.

A new satellite of Petermann Glacier in Greenland Study It has been revealed that its surface line changes its position with the ebb and flow of tides. This is the line where ice comes out of a glacier and comes in contact with the sea and floats on it. Scientists from the Jet Propulsion Laboratory of the American space agency NASA at the University of California, USA, said that due to this, hot water makes its way from under the glacier. According to this study, about 2.5 miles has slipped in the last few years. Due to this, the hot water of the sea has created a crater of 670 feet below it.

In this study published in the National Academy of Sciences, it has been said that due to the force of tides, the glacier comes in contact with warm water and its retreat increases. The findings add surprise to glaciologists trying to understand changes in Greenland’s ice. Billions of tons of ice have been lost in Greenland. Eric Rignot, a study co-author and professor of Earth System Science at the University of California, said, “This collision between ice and ocean causes more damage to glaciers than ocean warming. These findings were not included in the models. If we include them, this could increase the forecast sea level rise by 200 percent. This would be the case not only for Petermann, but for all glaciers along the sea.”

Due to the hot air, the ice slides over the glacier, but due to the high temperature of the sea, the ice in the lower part of the glacier gets cut and melts and goes into the sea. The retreat of glacier ice can also pose a threat to creatures that live in the ice. Last year, it was reported in a study that due to high air temperature, the water formed due to retreat of ice is rising in the sea.
