The Day the Earth nearly Died [View all]

Here's the end of the documentary which wraps it all up. But I would suggest watching the whole thing below. Fascinating like a detective thriller. This animal pictured is practically the only animal that survived somehow. It is the ancestor of all mammals.

The Permian Extinction occured 250 Millions years ago, which caused extinction of 95% of all living species in both animals & plants life. This extinction was slow and took nearly 80000 years in 3 stages: -
1- Increase in world temperature by 5 degrees Centigrade caused by super lengthy eruptions of Siberian Traps
2-melting the frozen reservoirs of Methane gas in the seabeds and releasing Carbon 12 (C12), which is a green house gas and raised sea temp by another 5 degrees,
3-world temp raised 10 degrees and that caused the mass extinctions

It took Earth millions of years to recover and after 20 million years the Dinosaurs first appeared.
