The huge Antarctic glacier, which is about the same size as the state of Florida in the United States, could be disastrous for the Earth if completely melted.
According to Mirror, the Antarctic Thwaites glacier is entering a period of 'instability' and in the worst scenario, all ice will melt into the ocean after only 150 years.
The giant glacier in Antarctica is melting.
As a result, the sea level will rise 2.5 times the level of 20cm since the late 19th century, a NASA study said.
NASA scientist Helene Seroussi said: 'After reaching the melting point, the Thwaites glacier will dissolve into the ocean for 150 years. That means the global sea level will rise by 50cm '.
The glacier Thwaites with a size of 181,000 km 2 is one of five glaciers that have double the melting rate in the last 6 years. The warming of seawater due to climate change is the main cause of instability.
The ice melts due to warm water impacting from below.
Seroussi scientist said the glacier became unstable when the sea was warmer than the impact from the bottom of the river.'This process is going on continuously, nothing can stop it.'
In January, scientists discovered a giant hole in the bottom of the Thwaites glacier. The hole has a surface area of approximately 40km2 and up to 300m. Estimates of holes are large enough to hold up to 14 billion tons of ice and most of them melt in just three years.
Thwaites are considered dangerous glaciers on Earth when responsible for about 4% of global sea level rise. At the same size as Florida, the United States, the Thwaites could cause oceans in the world to rise by 50cm, causing disaster for coastal cities.
