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

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…

Climate on Steroids in the Arctic

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…

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…

Extinction Events in Earth History and Today

Flood basalts and mass extinctions – ancient hyperthermals as analogs for anthropogenic climate change.  Oceanic Anoxic Event (OAE) and mass extinctions are considered to be hyperthermals – usually associated with flood basalt eruptions.[2] Phases of rapid global warming, known collectively as hyperthermals.[1]  Flood basalts are a subset of large igneous provinces (LIPs), the terms flood basalt…

The State of Arctic Permafrost Thaw (2019)

Soil layers of permafrost that scientists expected to remain frozen for at least 70 more years have already begun thawing. NOTES In the Canadian Arctic, layers of permafrost that scientists expected to remain frozen for at least 70 years have already begun thawing. The once-frozen surface is now sinking and dotted with melt ponds and…
