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 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…
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…
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…
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…
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…
Our previous understanding of how the Antarctic Ice Sheet responded to warming at the end of the last ice age 10 to 20 thousand years ago was based on only a few ocean sediment cores. From sediment cores in the North Atlantic we have been able to piece together a decent map of how and…
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…
The news is not new in scientific circles, but new research has somehow piqued the interest of the media and the word is out. The West Antarctic Ice Sheet (WAIS) is in the initial stages of irreversible collapse. This will ultimately lead to 13 to 20 feet of sea level rise in time frames between…
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…
Over the years I have been watching the reports reporting how sea level rise slowly increasing. Slowly however is a misnomer. Sea level rise has rapidly increased since about 1990. The papers tell the story. Throughout most of the 20th century, sea level rise was between 1.2 and 1.5 mm per year. About 1990, it…
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…
The West Antarctic ice sheet is the single most remote and inhospitable region on the surface of Earth. Because of its remoteness and hostility, research there is scarce. On our rapidly warming world today, and considering the possible climate threshold we have just crossed, collapse of the WAIS is a very important thing to understand….
