....the same day were all the fountains of the great deep broken up, and the windows of heaven were opened. Genesis 7:11
"The end-Permian mass extinction, also known as the Permian-Triassic extinction event and the Great Dying, is the largest mass extinction event in Earth’s history.... Massive eruptions in a 
volcanic system called the Siberian Traps are thought to have played an important role, .... Now, a research team led by Dr. Hana Jurikova has assembled a consistent biogeochemical reconstruction of the mechanisms that resulted in the end-Permian extinction.
The team’s findings showed that volcanic eruptions in Siberian Traps released immense amounts of carbon dioxide into the atmosphere.
Dramatic changes in chemical weathering on land altered productivity and nutrient cycling in the ocean, and ultimately led to vast de-oxygenation of the ocean.
The resulting multiple environmental stressors combined to wipe out a wide variety of animal and plant groups.
“We are dealing with a cascading catastrophe in which the rise of carbon dioxide in the atmosphere set off a chain of events that successively extinguished almost all life in the seas,” Dr. Jurikova said."
