In a groundbreaking study published in Nature Geoscience, researchers have identified a critical tipping point in Antarctica’s ice sheets, profoundly impacting future sea level projections. The study focuses on the mechanism of seawater intrusion, where warming seawater infiltrates between coastal ice sheets and their underlying grounding zones. This process initiates a destructive feedback loop: as …

New research utilizing radar data from space has revealed alarming insights about the Thwaites Glacier in West Antarctica, commonly known as the “Doomsday Glacier.” This study, published in the Proceedings of the National Academy of Sciences, highlights a significant increase in the vulnerability of the glacier, as ocean water is found to be pushing miles …

Sixty percent of the world’s freshwater is stored in Antarctica’s ice sheets. This equates to thirty million cubic kilometers of ice. If all of this ice was to melt, the seas would rise by 58 meters.

According to scientists, the deep ocean circulation that forms around Antarctica could be headed for collapse. A decline of this ocean circulation will stagnate the bottom of the oceans and affect climate and marine ecosystems for centuries to come. 

A new model suggests Antarctica’s ice shelves may be melting faster than previously thought. This model accounts for an often overlooked narrow ocean current along the Antarctic coast.

Researchers have found an unexpected river beneath the Antarctic ice sheet that affects the flow and melting of ice, potentially accelerating ice loss as the climate warms. Its discovery indicates the base of the ice sheet has more active water flow than previously thought. 

A new study using Copernicus Sentinel-1 data found that glaciers feeding the George VI Ice Shelf speed up by approximately 15% during the Antarctic summer. This is the first time seasonal cycles have been detected on land ice flowing into ice shelves in Antarctica. 

Warmer waters are flowing towards the East Antarctic ice sheet, according to alarming new research which reveals a potential new driver of global sea-level rise. 

Scientists are concerned that a potential volcanic eruption beneath Antarctica could lead to major global sea level rise. Beneath Antarctica’s ice sheet lie more than 100 volcanoes. 

Antarctica will be the largest source of future rise in sea level yet scientists know little about how this will unfold. New research shows how the Antarctic ice sheet advanced and retreated over the past 10,000 years.
