At the end of the last ice age, geological fingerprints recorded in ocean sediments suggests glacier retreat of 50 meters a day, 18 km a year.For comparison the fastest retreating glaciers in Antarctica today are the Pope, and the Smith glacier system, retreating about 2.9 km a year. The study data was obtained in the…
Significant changes have taken place on Denman Glacier and Shackleton Ice Shelf. The floating section of the glacier experiences vigorous ice melt in contact with the ocean, which suggests the presence of Circumpolar Deep Water. However, there is no historical oceanographic data near the glacier. https://www.pnas.org/content/116/4/1095 Denman Glacier, located in East Antarctica retreated about 5…
A new study suggests that the East Antarctica Ice Sheet in the Wilkes Basin may have completely disappeared around 400,000 years ago. Currently the Wilkes Basin is only hold back by the Cook, Mertz, and the Ninnis glacier – the Cook Glacier shelf has already collapsed. There is also the Totten Glacier farther to the…
In this talk from October 2019, Eric Rignot suggests the possibility of 4 meters of sea level rise per century. Just extrapolating based on Antarctic marine glaciers retreating would yield the figure Notes a new model with results in the ballpark Notes the figure is in agreement with past sea level rise estimates Not mentioned…

It has long be debated, estimated, projected when the Arctic Ocean becomes essentially ice free, in terms of the so called Blue Ocean definition – typically defined as less than 1 million square kilometers of ice, or less than 10% of the basin. YALE: Relentless high pressure and cloud-free skies have allowed the Arctic Ocean’s sea…

Experts of the field in studying one of the most puzzling regions in the Arctic for methane emissions, the East Siberian Arctic Shelf (ESAS) reported last October about the largest readings since studies started there 15 years ago. The region is known to be particular important due to it’s size, and low water depth, with…
