Expert talks Arctic Permafrost Thaw (May 2017)

At the event How is climate impacting the Arctic, what does this mean & what can we do? hosted by The Woods Hole Research Center (WHRC), at the University of Alaska Fairbanks May 11, 2017. Professor of Geophysics Vladimir Romanovsky discusses the impact of Arctic permafrost thaw. Related http://permafrostwatch.org This video is an event excerpt,…

Waking the Giant: Climate Force and Geological Hazards

Bill McGuire on the influence of climate change on geological systems, the link between episodes of major climate transition and geohazards (2012). Small changes in the Earth’s crust can potentially trigger large hazards such as earthquakes and volcanoes. Bill McGuire is Professor of Geophysical & Climate Hazards at UCL. He was a member of the…

San Andreas 2: Will Dwayne The Rock Johnson discover climate earthquakes?

In the 2015 disaster film San Andreas, Dwayne Johnson played Chief Raymond “Ray” Gaines, a Los Angeles Fire Department helicopter-rescue pilot, during a devastating earthquake in Los Angeles. According to Rotten Tomatoes consensus film rating, San Andreas has a great cast and outstanding special effects, but amidst all the senses-shattering destruction, the movie’s characters and…

Bill McGuire: Modelling suggests with ice cap melt, an increase in volcanic activity

ClimateState interviewed Bill McGuire, Emeritus Professor of Earth Sciences at the University College London, one of Britain’s leading volcanologists and contributing author to the 2011 IPCC report. He called for an early tsunami warning system (2004, The Guardian) and warned in his book The Waking Giant, of the Earth response (more earthquakes, tsunamis and landslides)…

Experts: Arctic craters could be ‘Visible Effect’ of Global Warming

The preliminary results from scientists studying the mysterious holes (craters), that began emerging in recent times in Siberia, indicate that climate change may be a cause. The Russian crater research team led by Alexei Plekhanov of the Scientific Centre of Arctic Studies, explained a possible mechanism, in a Nature interview. The past two summers were…

Rapid sea-ice loss may increase the rate of Arctic land warming by 3.5 times – affecting permafrost

Recently a mysterious Siberian crater has been discovered, which subsequently raised questions about the circumstances surrounding the crater formation.  Theories include Pingo formation and connections to the thawing of permafrost (ClimateState reported). Robert Scribbler, summed it up: One theory on the feature is that it might be a pingo — a melting of a permafrost water pocket…

Rebound an Earth Story


Glacial isostatic adjustment, why we have glacial and interglacial periods, how we can reconstruct climate history, and how the Earth is responding to the retreat of the continental glaciers.

Arctic methane outgassing on the East Siberian Shelf

SkepticalScience.com by John Mason on January 19 2012: In December 2011, following a fresh flurry of sometimes conflicting media reports about methane outgassing on the East Siberia Arctic Shelf (ESAS), we decided to go and talk to the people doing the work on the ground. We are pleased to report that Dr Natalia Shakhova (NS…

Evidence for Rainfall-Triggered Earthquake Activity

Fluids are known to be of major importance for the earthquake generation because pore pressure variations alter the strength of faults. Thus they can initiate earthquakes if the crust is close enough to its critical state. Based on the observations of the isolated seismicity below the densely monitored Mt. Hochstaufen, SE Germany, we are now…

A closer look at subglacial glacier cavities and water pressure

A collection of science around subglacial glacier’s, cavities and about water pressure/water flow. Though someone pointed out that most of the items are focused on land based glaciers, rather than on the WAIS which is a marine ice sheet. However, i welcome all contribution in the comment section which helps to better understand marine ice…

First evidence of under-ice volcanic eruption in Antarctica

The first evidence of a volcanic eruption from beneath Antarctica’s most rapidly changing ice sheet. The volcano on the West Antarctic Ice Sheet erupted 2000 years ago (325BC) and remains active. Using airborne ice-sounding radar, scientists from British Antarctic Survey (BAS) discovered a layer of ash produced by a ‘subglacial’ volcano. It extends across an…
