Scientists Detect Signs of Abrupt Climate Shift in Arctic

Ice cores obtained years ago document an ominous rise of temperatures, abrupt change manifesting just within a few decades. First scientists thought this must be an error, but slowly they realize what it could mean for us today. Research into the polar ocean, found, it is getting hotter at a rate faster than even the worst…

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…

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…

Climate on Steroids in the Arctic, Blue Ocean Event 2020?

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…

Extinction Events in Earth History and Today

Flood Basalts and Mass Extinctions – refine 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 Current State of Arctic PERMAFROST THAW

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…
