Methane Hydrates Being Released From Gulf Oil Spill Responsible For Dinosaur Extinction

According to newscientest.com the release of release of four trillion tons of methane hydrates has been linked to extinction of Dinosaurs.

The article states that possible reasons for the massive destabilization and release of the frozen methane gas “include large shock waves from meteorite impacts, strong greenhouse warming or a dramatic reduction in sea level”.

The release of massive clouds of methane from icy hydrates buried under shallow ocean floors is the leading suspect for the most devastating extinction in the fossil record, according to a new analysis.

Methane best matches the unusual carbon-isotope fingerprints found at the scene of the crime, says Robert Berner of Yale University in Connecticut, US, though it cannot explain atmospheric carbon dioxide levels at the time.

Berner says: “It’s possible that you could have a combination” of effects causing the mass extinction that ended the Permian period, 250 million years ago. The event wiped out the vast majority of marine species and left Europe a near-desert.

Many theories have been proposed to explain the extinction, including a comet or asteroid impact. Other ideas focus on two unusual events at the end of the Permian – the eruptions of two million cubic kilometers of lava across Siberia and unusual stratification of the oceans.

Some have even suggested that the mass dying itself – shown by a sudden abundance of fungi spores at the boundary – could have itself had affected global carbon cycles. Yet solid support for any one theory has been lacking.

Some have suggested that the massive discharge of large amount of oil from the Gulf oil spill may cause the seafloor collapse which could trigger earthquakes, tidal waves or even a massive Yellowstone Caldera volcanic eruption type event (which would be an extinction event itself).

In fact hundreds of people and dozens of bloggers watching the BP Live Video Webcam Feed of Gulf Oil Spill have reported huge explosions and the collapse of the seafloor beneath the Gulf oil spill.
