Undersea volanoes did it |

#8 Baba, it was not the cause of the mass extinctions at the end of the Cretaceous (that may have been a comet or meteor that hit the Yucatan), but it may well have been the cause of a smaller mass extinction of marine life forms at the end of the Cenomanian (subdivision of the Cretaceous). The end of the Cenomanian is notable for having the highest overall sea level of the last 600 MY (as best we can tell.) I am not sure whether volcanoes were a cause, or just another effect of whatever the cause was, but the Cenomanian was quite an interesting time. |

#7 The late Cretaceous ended 65 million years ago, not 93. But what's 30 million years if you're the BBC? |

#4 Beware this PC article from the BBC. As the Earth actually cools over the next few years, expect claims that man-made atmospheric CO2 is turning into carbonic acid that will cause a similar PH decrease in the oceans. You see, CO2 isn't warming the atmosphere, it's acidifying the oceans. Different decade, different lie. |

#3 I blame Bush. |

#2 This stuff can be pretty nasty. North of Sicily there is an undersea volcanic area that has turned the water harshly acidic. It is sterile ocean, and only robotic probes can dive in it. |
