Siberian Flood Basalts – MIT: About 252 million years ago, the largest mass extinction and the largest volcanic eruptions in Earth history occurred apparently synchronously. Massive volcanic eruptions set the stage for dinosaurs’ demise http://arstechnica.com/science/2014/12/massive-volcanic-eruptions-set-the-stage-for-dinosaurs-demise/ Bill McGuire: Modelling suggests with ice cap melt, an increase in volcanic activity https://climatestate.com/2014/10/16/methane-hydrate-destabilisation-is-clearly-a-real-worry-particularly-in-the-context-of-warming-ocean-waters-in-the-east-siberian-continental-shelf/ Siberian Traps http://en.wikipedia.org/wiki/Siberian_Traps Deccan Traps http://en.wikipedia.org/wiki/Deccan_Traps

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…

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…

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…

Volcanic Eruptions Add to Larger Impact on Climate

The recent slow down in global warming has been attributed to a number of factors, including excess heat being stored in the deep ocean and reductions of certain greenhouse gases. Now add volcanic eruptions to the mix of contributing factors. A new analysis published in Nature Geosciences on Sunday shows that a series of relatively small…
