Did the Oceans Cause the Extinction of the Woolly Mammoth?

The Paleao Police have arrested the Storegga Slide, alleging its role in the extinction of the woolly mammoth and other megafauna, ending a 206-year investigation. The case hinges on the relationship between the Storegga Slide, which occurred around 8,200 years ago, and climate changes that may have contributed to mammoth extinction approximately 10,000 years ago. Discussions highlight the destabilization of methane hydrates due to ocean warming, which could have caused significant climate shifts and extreme weather events. Evidence suggests that these changes could have led to increased precipitation and altered ocean currents, impacting mammoth habitats. The debate continues over the extent of human influence versus natural events in these mass extinctions.

You're welcome and there is plenty more where this is coming from. For instance the methane hydrate events in the Nordic seas are in pace with the 100,000 years cycle as seen in the Antarctic ice cores, See http://www.sciencedirect.com/science?_ob=ArticleURL&_udi=B6V9Y-4GY89XG-3&_user=10&_coverDate=12%2F31%2F2005&_alid=831212007&_rdoc=3&_fmt=high&_orig=search&_cdi=5911&_docanchor=&view=c&_ct=7&_acct=C000050221&_version=1&_urlVersion=0&_userid=10&md5=68346cb2f38caf58685799820c9b117f.

But similar things happened at the mouth of the Amazon: http://www.sciencedirect.com/science?_ob=ArticleURL&_udi=B6VBC-4N2D64D-2&_user=10&_coverDate=04%2F30%2F2007&_alid=831217205&_rdoc=1&_fmt=high&_orig=search&_cdi=5923&_docanchor=&view=c&_ct=7&_acct=C000050221&_version=1&_urlVersion=0&_userid=10&md5=b01dfbf6718cccf4065ce8b81db28fbf.

Apparantly the oceans went rogue at times, causing destabilisation of methane hydrate and also http://www.sciencemag.org/cgi/content/abstract/1138679v1 into the atrmosphere, but why and how and what is cause and what is effect?

I'm sure they are on to something, but what? It should be clear though that -contrary the assessment of the IPCC- we are nowhere near understanding the influence of the oceans on paleo climate
