    to the 6th mass extinction event, already underway.

    This is an edited version of the first such event.

    Many researchers believe the extinction was more gradual, resulting from the sea level and climate changes already occurring during the late [20th C]

    But all of these other events were natural. So sad that we could be so stubborn and foolish, but there it is.

    And remember: if we fail on climate change, nothing else matters. - WarrenS

      But unfortunately, while I've been talking for many years to people about the fact that we are already seeing a mass extinction event I get mostly blank looks.  It literally doesn't compute for most everybody - even people who are not total wingnuts.

      It's incredibly frustrating.

    •  Actually that's the *fifth* one. (4+ / 0-)

      The first was Ordovician-Silurian (444 million years ago, 60% extinction).
      The second was Late Devonian (374 and 360 million years ago, double-pronged events with ~50% extinction each).
      The third was the biggie: Permian-Triassic, 252 million years ago, over 90% extinction!
      The fourth was Triassic-Jurassic (200 million years ago, "only" about 20-30% extinction).
      The dino-wipeout event (Cretaceous-Tertiary/Paleogene) was a bit worse than the fourth, but peculiarly hit-or miss (got all the dinos, but a lot of other species made it).

      If it's
      Not your body,
      Then it's
      Not your choice
      And it's
      None of your damn business!
