Hello? Where has everyone been? I have been saying this for years. This is not a big revelation. Did the Indian government the reality of the Permian or what?
The Permian extinction has always been the largest extinction of life on Earth. 95% of all marine life died because of the 'heat' of the oceans resulting in crenation of the microscopic 'primary producers.' The primary producers are those that are the cornerstone to all life. The microscopic plants and plankton that use photosynthesis to fuel their life. The primary producers are the bottom of the food chain and are 'supposed' to be the most abundant. They are what every other species feed on either directly or indirectly through it's food chain.
Scientists/archeologists/geologists for a long time believed all extinctions of which there are five complete were due to glacial periods. The Permian Extinction was believed to be to glaciation until further evidence of ice cores pointed to very high levels of greenhouse gases in the troposphere. The geologic investigators then realized The Permian Extinction was caused by Global Warming. It was the heating of the seas and oceans that collapsed the fisheries.
I am pleased to realize India and I are finally on the same page.
Biggest extinction wasn't caused by asteroid or comet:Report:
[India News]:
New Delhi, Jan 21 :
The biggest mass extinction in the history of earth some 250 million years ago was caused by global warming and not by the impact of asteroid or comet as earlier believed, new evidence has indicated.
In a paper published by Science Express, the online version of the journal Science, yesterday researchers headed by University of Washington scientist Peter Ward said they have found no evidence for an impact at the time of "the Great Dying" 250 million years ago.
Instead, their research indicates the culprit might have been atmospheric warming because of greenhouse gases triggered by erupting volcanoes.The extinction occurred at the boundary between the Permian and Triassic periods at a time when all land was concentrated in a supercontinent called Pangea.
The Great Dying is considered the biggest catastrophe in the history of life on Earth, with 90 per cent of all marine life and nearly three-quarters of land-based plant and animal life going extinct."The marine extinction and the land extinction appear to be simultaneous, based on the geochemical evidence we found," their paper said."Animals and plants both on land and in the sea were dying at the same time, and apparently from the same causes too much heat and too little oxygen."
