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…

Antarctic & Greenland Melt Accelerates Sea Level Rise (Eric Rignot October 2019)

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…

When will the Netherlands disappear below sea level?

It’s difficult to imagine, but currently the Netherlands is on a trajectory to be swept away by sea level rise. Previous measures are no longer sufficient enough in light of more recent knowledge. The question is not if the Netherlands will disappear below sea level, but when https://www.uu.nl/en/news/the-question-is-not-if-the-netherlands-will-disappear-below-sea-level-but-when As sea levels rise, how long until…

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…

Eric Rignot: On the Current State of Sea Level Rise Estimates (2019)

Glaciologist Eric Rignot (NASA/JPL) speaking at the American Philosophical Society meeting April 2019. Climate warming caused by human activities has woken up the sleeping ice giants in Greenland and Antarctica, elevating risks of multiple meters of sea level rise in the coming centuries. Rignot will discuss how satellites, airborne platforms, robotic devices and advanced numerical…

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…
