Greenland Ice Sheet Collapse Can Be Controlled


More than 860,000 square miles out of the total surface of Greenland are covered with glaciers and ice, but they are melting, which causes the sea level in Florida to rise by one third. A team of the University of South Florida has found this way why there is a special significance to the collapse of Greenland’s glaciers into the sea. Can this be avoided?

What does the study say about the Greenland ice sheet collapse?

A group of scientists led by USF Distinguished University Professor Tim Dixon, Ph.D., published the research in Nature Communications explaining the process they have discovered. It can be used to control Glaciers’ calving – the term stands for the icebergs that form due to the large chunks of glacier ice collapsing into the sea.

The scientific community gets helped this way to model future sea-level rise and Greenland ice loss better thanks to the team. The group includes experts such as Denis Voytenko, Ph.D., formerly at NYU and now at Nielson Communications, USF Ph.D. student Surui Xie, and David Holland, Ph.D., and Irena Vaková, Ph.D., at New York University (NYU) and NYU-Abu Dhabi Research Institute.

How severe is this issue, and what can we do against it?

Climate change’s most dramatic effect is glacier calving. This term explains the process of an ice structure falling into the sea. Usually, this big piece of ice is almost as tall as a skyscraper. One such calving has been caught on video by Tim Dixon’s team. According to Dixon, it is not easy to model iceberg calving as it is one of the least understood mechanisms that makes Greenland fall apart and rises sea levels.

The team wanted to understand the process more deeply, so they installed a new radar system when they ventured to Greenland in the summer of 2016.
