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…
The study New constraints on atmospheric CO2 concentration for the Phanerozoic (DOI: 10.1002/2014GL060457), by Peter J. Franks, Dana L. Royer, David J. Beerling , Peter K. Van de Water, David J. Cantrill, Margaret M. Barbour, and Joseph A. Berry, estimates CO2 in Earth history based on a new climate proxy. Estimates are in particular based…
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…
Wikipedia: A flood basalt is the result of a giant volcanic eruption or series of eruptions that coats large stretches of land or the ocean floor with basalt lava. Flood basalt provinces are often called traps, which derives from the characteristic stairstep morphology of many associated landscapes. Related Greenland ice sheet collapse, triggered ancient sea…
Evidence indicates that the Jamal sink hole (Siberia) has been caused by permafrost thaw, still under investigation. New footage (July, 18 2014) shows the crater in more detail, and Dan Miller explains the interconnections of climate change and permafrost. Anna Kurchatova: Siberia’s frozen soil — known as permafrost — contains millions of tons of methane…
Salon: According to Anna Kurchatova, with the Sub-Arctic Scientific Research Centre, the hole could have to do with the thawing of Siberia’s permafrost, a consequence of global warming. The rapid release of gas previously trapped in the ice, she said, could have combined with sand beneath the surface to form an underground explosion. The Siberian…
DeSmog Canada published a series of aerial photos from Canada Alberta. Alex MacLean is one of America’s most famed and iconic aerial photographers. His perspective on human structures, from bodies sunbathing at the beach to complex, overlapping highway systems, always seems to hint at a larger symbolic meaning hidden in the mundane. By photographing from above, MacLean shows…
Introduction to Methane Hydrate “Methane Hydrates and Contemporary Climate Change” (2011) IDENTIFICATION This post “A Mechanism for Shallow Methane Hydrate Dissociation”, explores possible mechanism which could release vast quantities of shallow Methane Hydrate into the ocean and atmosphere. CH4 Release The following studies explore the release of CH4 emissions in the Arctic region. OBSERVATION…
