The newly discovered ‘positive feedback loop’ results in deeper waters retaining their temperature, while hastening the process of glacial melt, which could have a negative effect on the world’s sea levels.

Highlights:

  • Sea level rise could be happening at a faster rate than previously thought, as scientists have identified a new source of melting ice in Antarctica.

  • Antarctica is one of the many areas that could be melting faster as warm water trapped underneath it accelerates the process Alessandro Silvano

  • Contrary to the scientists initial thoughts, more of the Totten Glacier has been found floating in Antarctica.

  • New study shows that global warming is melting the Totten Glacier fast.

  • Researchers spotted many of them floating when they were supposed to be grounded.

  • In a study published in the journal Science Advances, a team led by University of Tasmania Institute for Marine and Antarctic Studies (IMAS).

About Totten Glacier

  • Totten Glacier is East Antarctica’s largest outlet of ice to the ocean and has been thinning rapidly for many years.

  • It is approximately 65 km long and 30 km wide and contains enough ice to raise global sea levels by at least 3.5 m.

Tasmania Institute for Marine and Antarctic Studies (IMAS): -

  • Is an excellent centre of excellence for research and education at the University of Tasmania.

  • IMAS has three core research programs

  • The melting of ice on Antarctica alone could cause seas to rise more than 15 meters.
