The Thwaites Glacierlocated in West Antarctica and known as the “Giudizio Glacier“, is melting at a faster rate than previously thought, due to the influence of warm ocean waters and the consequences of global warming. This is putting many coastal communities at risk.
Thwaites Glacier, it could dissolve much more quickly of the expected as recent satellite observations suggest. This data shows that warm ocean waters are affecting the glacier more significantly than previously believed. Nicknamed “the doomsday glacier”, it is the focus of in-depth studies for its potential consequences on sea levels.
The accelerated melting of glaciers has already had tangible effects on Earth, such as slowdown of the planet’s rotation speed. This phenomenon led to the elimination of the leap second from the solar year, changing the Coordinated Universal Time (UTC) policy three years earlier than expected. Such changes affect critical sectors such as information technology and financial markets, where time precision is critical and the introduction of leap seconds cannot be planned in advance.
The Thwaites Glacier, which covers an area of 120,000 square km, could cause a sea level rise of as much as 64 cm if it were to melt completely. This would leave many coastal communities around the world vulnerable. The particular instability of the immense frozen body is due to the fact that it is located on downward sloping terrain, facilitating erosion by ocean waters.
Water that penetrates its base accumulates and moves through natural channels and cavities, creating pressure and lifting the ice cover. This movement accelerates the melting of the glacier, as themelted fresh water is replaced by warmer sea water.
By the way, do you know what would happen if the ocean water was no longer salty?
