The Pine Island Glacier and the [[Thwaites Ice Tongue]] are two of Antarctica's five largest ice streams. Scientists have found that the flow of these ice streams has accelerated in recent years, and suggested that if they were to melt, global sea levels would rise by 1 to 2 m (3 ft 3 in to 6 ft 7 in), destabilizing the entire [[West Antarctic Ice Sheet]] and perhaps sections of the [[East Antarctic Ice Sheet]]. | The Pine Island Glacier and the [[Thwaites Ice Tongue]] are two of Antarctica's five largest ice streams.

==Subglacial volcano== | ==Subglacial volcano== | ||
In January 2008 the British Antarctic Survey (BAS) scientists, Hugh Corr and David Vaughan, reported that 2,200 years ago a volcano erupted under the Antarctic ice sheet. This was the biggest Antarctic eruption in the last 10,000 years. The volcano is situated in the [[Hudson Mountains]], close to Pine Island Glacier. The eruption spread a layer of volcanic ash (or tephra) over the surface of the ice sheet. This ash was then buried under the snow and ice. Corr and Vaughan were able to map this ash layer using an airborne radar system and calculate the date of the eruption from the depth of burial of the ash. This method uses dates calculated from nearby ice cores. The presence of the volcano raises the possibility that volcanic activity could have contributed, or may contribute in the future, to increases in the flow of the glacier. | [[File:Pine Island Map.png|350px|thumb|Detailed map showing the features surrounding the Pine Island Glacier.]] | ||

==Peerage title== | |||
On 10 September 2019, Florian Lohwasser was granted the [[Peerage of Westarctica|peerage title]] Baron of Pine Island. Although [[Grand Duke Travis]] attempted to dissuade him from selecting this region as his title due to the high probability that the glacier will be gone in less than a decade, the Baron insisted on adopting the name, stating: "I would like to use the 'Pine Island Glacier' and spread the word about the glacier's tragic situation." | |||
