These are the world's most majestic glaciers

Scroll through the gallery to see more of the world's majestic glaciers. As the world's temperatures rise, glaciers are melting and scientists are looking for ways to forecast their retreat. One possibility is listening to the sounds made by glaciers. Oceanographer Grant Deane has been trying to quantify the ice melt using acoustic technology, with most of his work focused on Hans Glacier also known as Hansbreen in Svalbard, Norway. This glacier has retreated around 2.7 kilometers between 1900 and 2008 according to a study published in the Cryosphere.

Pine Island is one of the fastest-retreating glaciers in Antarctica. Satellite images like this one have been key to its retreat and major calving events when a block of ice breaks off from the end of the glacier In recent years, the glacier has shrinked faster due to the increase in the calving rate.

The European Space Agency has recently entered a new phase of rapid retreat, and around 3.5 trillion metric tons of ice have been melted from the Greenland ice sheet and spilled into the ocean, enough to cover the UK with meltwater almost 50 feet deep.

Helheim, named after the realm of the dead in Norse mythology, is one of the great glaciers in Greenland. It is more than four miles wide and is roughly the height of the Statue of Liberty. According to a 2020 study published in the Nature Communications, it holds enough ice to raise the sea level by four feet, together with Kangerlussuaq and Jakobshavn Isbrae.

The Vatnaj kull Glacier in Iceland is the biggest in Europe, covering an area of more than 3,000 square miles, which is three times larger than Luxembourg. The ice cap covers several active volcanoes that cause glacial floods when they erupt. NASA Vatnaj kull is losing ice quickly, shrinking in volume by about 15% in the past century.

Hubbard Glacier, in Alaska, is seven miles wide and is North America's largest tidewater glacier that ends in the ocean. It is currently considered in a stable position and in 2015 NASA reported that it has steadily grown over the past 100 years.

Perito Moreno, located at the southern end of Patagonia in Argentina, is one of the world's last non-retreating glaciers More than 18 miles long. It is one of the biggest in Patagonia and descends from an elevation of almost 7,000 feet in the Andes Mountains to the turquoise waters of Lake Argentino, about 600 feet above sea level.
