Alaska’s permafrost is starting to thaw as the climate warms, and scientists project there will be even greater thawing of the frozen soils in the coming decades, releasing carbon into the atmosphere, and impacting ecological systems and infrastructure. A panel of permafrost experts will unveil new findings about permafrost degradation in Alaska, where permafrost covers…
NAS member Richard Alley presents on 4.6 Billion Years of Earth’s Climate History: The Role of CO2, during the Symposium—Earths, Moons, Mars & Stars at the National Academy of Sciences 152nd Annual Meeting.
A reservoir of abiotic methane has been discovered in the Arctic Ocean. This means that there is more of the greenhouse gas trapped under the seabed than previously thought.

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…
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,…
Siberian Flood Basalts – MIT: About 252 million years ago, the largest mass extinction and the largest volcanic eruptions in Earth history occurred apparently synchronously.

On Monday The Weather Channel reported (includes video footage), quote: The Pico do Fogo volcano on the Cape Verde island of Fogo, off West Africa, erupted Sunday and prompted the evacuation of at least one nearby village. The government said it was the first time the volcano has erupted in 20 years. The event is…
Climate State 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…
