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…

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 Narration by Cormac Bren 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…

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”. Read about his newest…

Global Warming and Changes in East Antarctic Glaciers #AGU2018

https://www.youtube.com/watch?v=2P9X7lLl5Iw East Antarctica, which holds the potential of raising global sea level by almost 200 feet, has long been considered stable and unlikely to change in the future. But recent observations have hinted that East Antarctica is starting to wake. #TottenGlacier In this briefing, researchers will present new findings on how a group of glaciers…

Did a Greenland Asteroid Cause Abrupt Warming Last Ice Age?

We report the discovery of a large impact crater beneath Hiawatha Glacier in northwest Greenland. From airborne radar surveys, we identify a 31-kilometer-wide, circular bedrock depression beneath up to a kilometer of ice http://advances.sciencemag.org/content/4/11/eaar8173 Hiawatha Glacier https://en.wikipedia.org/wiki/Hiawatha_Glacier Sources Discovering a massive meteorite crater https://www.youtube.com/watch?v=hQ9maLsIcts Massive crater under Greenland’s ice points to climate-altering impact in the…
