The Siberian Traps and Volcanic Mass Extinction

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 http://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

Everything you need to know about Mass Extinction, Sea Level Rise and Amplification

Professor Peter Ward (Professor, Sprigg Institute of Geobiology, The University of Adelaide) explains the interconnections of rising carbon dioxide levels and flood basalt, and how it leads to anoxic oceans (with Hydrogen sulfide). Ward explains how today’s CO2 levels will result in sea level rise with disrupting implications for crops and how deglaciation will ultimately…

Anoxia and Euxinia Ocean Environmental Change

Reconstructing the history of euxinia in a coastal sea Caroline P. Slomp, 2013 DOI 10.1130/focus0420131.1 Web http://geology.gsapubs.org/content/41/4/523.full Areas of the coastal ocean where oxygen is low or absent in bottom waters, so-called dead zones, are expanding worldwide (Diaz and Rosenberg, 2008). Increased inputs of nutrients from land are enhancing algal blooms, and the sinking of this…
