The Day The Earth Nearly Died

The Day The Earth Nearly Died is a British documentary produced by BBC to the science and philosophy series Horizon in 2002.

In the program, it is argued that the Permian extinction came in 3 stages; the first was caused by volcanic activity in the great Siberian Traps.

This is proposed to have caused global warming, which in turn killed much of the life on land.

As the sea became warmer, the ocean floor released a massive amount of methane.

As the methane reached the atmosphere, the earth became even warmer, which led to the extinction of even more lifeforms on land.
