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…

Ancient 5,000-Year-Old Forest Unearthed by UK Storms

A sign for extreme change is when storms destroy ancient landmarks, unearth 1 million old foot prints (See video above) or reveal  pottery from the Iron Age and Romano-British time. Now they discovered ancient forest stumps. The BBC explains: Geologists believe extensive forests extended across Mount’s Bay in Penzance between 4,000 and 6,000 years ago. The shifting sands have also revealed…

Thawing Permafrost Could Release Vast Carbon Deposits, Diseases

by Science World Report | January 8, 2014 | Release URL Dr Guido Grosse has been studying the Arctic for fourteen years to find out how the frozen ground, known as the permafrost, is reacting to an environment that is getting hotter all the time. The samples he has drilled out – in regions so…

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…

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…

Understanding the long-term carbon-cycle: weathering of rocks – a vitally important carbon-sink

By John Mason / SkepticalScience   above: the processes of the long-term carbon-cycle that this post explores. Graphic: jg. This post delves into the long-term carbon cycle that involves the interactions of the atmosphere with rocks and oceans over many millions of years. Because of its length, I’ve broken it up into bookmarked sections for…
