NASA Studies Find Previously Unknown Loss of Antarctic Ice

New research on Antarctica, including the first map of iceberg calving, doubles the previous estimates of loss from ice shelves and details how the continent is changing. NASA: The greatest uncertainty in forecasting global sea level rise is how Antarctica’s ice loss will accelerate as the climate warms. Two studies published Aug. 10 and led…

The Denman Glacier and Shackleton Ice Shelf

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…

The Doomsday Glaciers in East Antarctica | Earth Under Water

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…

Ice Tsunamis: Can Ice Stream Collapse accelerate Sea Level Rise?

A Never-Before-Seen Event Is Collapsing an Ice Sheet in the Russian Arctic – Will ice stream collapse accelerate Sea Level Rise super extreme? Scientists have discovered a rare event, a collapsing ice sheet. With already multi meter sea level rise estimates from global warming, this highlighted event may accelerate trends further, with serious implications for…

Global Warming Explained in 1956

Published in 1956 for American television by the California Academy of Sciences. Bernard Hubbard explains how glaciers retreat, he mentions how since 1857 glaciers recede worldwide. Hubbard also explains the ice albedo effect, and how glaciers disintegrate. This program is devoted to glaciers, and also includes a promo for the Academy of Sciences. SPEAKER Bernard…

Multi Meter Sea Level Rise, Antarctic Sea Ice & Ice Melt Acceleration

A pair of new studies released on Monday share a same ominous message — that our planet’s ice is melting at an alarming rate, which is bad news for global sea levels. https://edition.cnn.com/2019/01/14/world/climate-change-antarctica-ice-melt-twin-studies/index.html Antarctic ice-sheet sensitivity to obliquity forcing enhanced through ocean connections https://www.nature.com/articles/s41561-018-0284-4 Four decades of Antarctic Ice Sheet mass balance from 1979–2017 https://www.pnas.org/content/early/2019/01/08/1812883116…

Eric Rignot: Response of the Great Ice Sheets to Climate Warming

In ca 2012, as part of the Discover the Physical Sciences Breakfast Lecture Series at the University of California, climate researcher Eric Rignot (NASA/JPL) outlined our understanding of changes in the major cryosphere hotspots in Antarctica and Greenland, in his talk titled “Response of the Great Ice Sheets to Climate Warming”.
