Clathrate gun kills Pleistocene mega fauna.

    Kind of hard to have palaeo climate discussions here. Also hard to figure out where to start the thread with a new hypothesis, about what caused the extinction of the Mammoths. Biology? Theory development? or Earth. Since there is a lot of Earth changes going on I choose for the latter.

    BTW the answer to the question is the Clathrate gun (Kennett et al).

    My guess is that the Clathrate gun did more than causing Tsunamis, it created a dramatic precipitation increase, possibly world wide, that destroyed the arid Mammoth steppe, the essential biotope for the Megafauna.

    A first draft is here


    But this was too difficult. the real article has been simplified. Nowadays I would think that the pulsating equator was the trigger for both the clathrate events and probably also a major cause of the ocean-current induced dramatic change in precipitation patterns.
