West Antarctic Ice Sheet Collapse: The Critical Path

By Abrupt changes, Climate Catastrophes, ice sheet, ice sheets, Impacts, Oceans, Sea Level Rise, West Antarctic Ice Sheet

    West Antarctic Ice Sheet Collapse: The Critical Path Article link Sea level rise estimates of around 10 feet by 2100 are now becoming hard to ignore. This article is about several new findings in 2018 that build on near-10 feet of sea level rise news from NOAA in 2016 and 2017. What is…

Another Big Antarctic Calving From New Underice Melt

By Abrupt changes, Glaciers, ice sheet, submarine channel, West Antarctic Ice Sheet

Another Big Antarctic Calving From New Underice Melt Ice scientists have been warning us since 2006 that the West Antarctic Ice Sheet (WAIS) has begun its collapse. Giant icebergs are a symptom that collapse initiation is underway. The continuing laissez-faire attitude of the press to these events is counter intuitive and even dangerous, and represents…

Ice Loss During Antarctic Cold Reversal May Spell Trouble for WAIS Collapse

By Abrupt changes, Glaciers, Gulf Stream, ice sheet, Oceans, underice, West Antarctic Ice Sheet

Fifty-two feet of sea level rise occurred in 400 years, 14,500 years ago with ocean and collapse conditions similar to today. We were coming out of the last ice age then, but then, forcing was thousands of times less than today. Our climate’s most meaningful and common changes are classified as abrupt changes in climate…

Fairness Bias: Big Misstatements in NYT Antarctic Ice Article

By Abrupt changes, ice sheet, Impacts, Oceans, Sea Level Rise, underice, West Antarctic Ice Sheet

This New York Times article from May has compiled the best of current Antarctic science images into a huge three-part piece, but some of the most important reporting is completely wrong. And most importantly, the way it is wrong exemplifies the impacts of the Climate change Counter Movement and how they have influenced the media’s…

West Antarctic Ice Sheet (WAIS) Collapse: The Latest Case for Zero Warming

By Abrupt changes, Climate Policy, Climate Reform, ice sheet, Oceans, Sea Level Rise, Strategy, underice

New research has for the first time defined the tipping point between a stable WAIS and an Antarctica that collapses uncontrollably. Potsdam Institute researchers (Levermann and Feldmann) tell us is that if we do not return our oceans to their preindustrial temperature by 2050, we will see out of control collapse of the WAIS and…

NOAA — Ice Sheet Collapse in Our Time: Zero Warming Climate Solution

By Abrupt changes, adaptation, Climate Policy, CO2 Removal and Sequestration, Emissions, Emissions Scenarios, ice sheets, in-depth and Popular Press, modeling, Negative emissions, Sea Level Rise, Solutions, West Antarctic Ice Sheet

We have delayed too long and now must urgently reduce the load of warming gases already emitted to our sky. We have been warned this would happen for decades, we just didn’t think it would happen so soon. This is exceedingly bad news, though the good news with climate change is very good indeed. The…

West Antarctic Melt Rate has Tripled

By Glaciers, ice sheet, ice sheets, Sea Level Rise, West Antarctic Ice Sheet

Researchers at UC Cal Irvine and NASA, using four different measurement techniques, have found that West Antarctica’s ice loss has tripled since 1992. The measurements looked at glaciers discharging to a west central location of West Antarctica called the Amundsen Sea Embayment (see Amundsen Sea in the map on the right). This could possibly be…

Ice Sheets Behaving Badly

By Sea Level Rise, Uncategorized

The most recent discoveries in climate science bear little resemblance to what we hear in the media. Greenland’s melt in 2012 for example has been widely advertised in the media as just another weather event, similar to many in the past. The adage that we cannot tell for sure if any single weather event was…

West Antarctic Ice Sheet May Have Begun Its Collapse

By West Antarctic Ice Sheet

Institute of Theoretical Geophysics, Department of Applied Mathematics and Theoretical Physics, University of Cambridge, Wilberforce Road, Cambridge CB3 0WA, UK Abstract: Recent observations of the West Antarctic Ice Sheet document rapid changes in the mass balance of its component glaciers. These observations raise the question of whether changing climatic conditions have triggered a dynamical instability…
