David Archer – Subsea Permafrost and the Methane Cycle on the Siberian Continental Shelf

ARCTIC-WISE: Bridging Northern Knowledges of Change Subsea Permafrost and the Methane Cycle on the Siberian Continental Shelf: Predictive Modelling for Climate Change David Archer, Geophysical Sciences, University of Chicago Tuesday, March 10, 2015, 5-6:30 pm A numerical model called SpongeBOB is used to simulate the hydrology and methane cycle on the Siberian continental shelf. Lowered…

Siberian Arctic permafrost decay and methane escape

Widespread seafloor gas release from the seabed offshore the West Yamal Peninsula, suggests that permafrost has degraded more significantly than previously thought.  Gas is released in an area of at least 7500 km2 in water depths >20 m.((Offshore permafrost decay and massive seabed methane escape in water depths >20 m at the South Kara Sea shelf | http://onlinelibrary.wiley.com/doi/10.1002/grl.50735/abstract | Alexey Portnov,…

BOOM: Oil Price Collapse and why it is Important

I recently mentioned, get out of fossil energy while you still can, when the price for crude was at $64.82. Though, today it has approached $55.84, with many oil guys loosing a fortune, oil billionaire Hamm lost half his fortune in three months. And the New York Times noted, free fall in oil price underscores shift…

Natural Gas versus Coal Power Plants: Greenhouse gas warming

Ken Caldeira: We had a paper come out comparing effects of natural gas versus coal plants, aimed at understanding how much methane leakage there could be from natural gas before it caused more near-term warming than coal. The answer depends on how efficient the different power plants are, but one thing that is clear is…

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…
