More bad news is coming regarding the glaciers and ice sheets from Antarctica. The Western part of Antarctica is getting thinner and weaker over the past century, and more than 24% of the ice is in danger of collapse. Other places from Antarctica have glaciers that have thinned by approximately 122 meters. The loss has to do a little with weather fluctuations, but also with decades of Earth’s climate getting warmed.
What Is the Study Saying?
Thwaites and Pine Island are Antarctica’s two biggest glaciers and are melting faster now than the first survey from 1992. The two glaciers are melting five times faster, and the scientists are trying to determine and examine the ice changes. The material consulted has been recorded between 1992 and 2017 by the European Remote Sensing satellites, and 800 million measurements have been made.
Also, the researchers have used the measurements to calculate the volume of Antarctica’s ice mass without the fluctuation from the snowfall that accumulates in seasonal cycles. The results have shown that some areas of Antarctica are damaged and especially on the Westside. We are talking about 415.000 square kilometers of ice that is an imbalance on the West side of Antarctica, but that’s not all the land that extends North has some problems as well. A portion of 17.900 square km of ice is dangerously unstable in North, and 57.000 km of ice is unstable in East.
To sum up, the changing in the glacier ice has been detected with the help of the fallen snow, and now they have a clear vision of the most vulnerable glaciers of Antarctica. The melting ice in Antarctica has led to a sea level rise since 1992 with 5 millimeters. When you look at the numbers, maybe it doesn’t sound so much, but in the long term, the biggest reserve of water will melt, and we will have a higher sea-level.
