  3. Snoopy @2 , 

    Antarctic ice loss has averaged about 13 cubic kilometers per year since 2001 , but has accelerated in the past 10 years.  (Still quite small ~ under 10% of the ice loss from Greenland.)

    Source: Rignot et al., 2019 (Proceedings of National Academy of Sciences)

  4. Sorry ~ my apologies to Snoopy, but I misquoted Rignot et al.

    The Antarctic ice loss is more than ten times bigger than I said.

    ( 2009--2017 ice loss is about 250 cubic kilometers per year. )

    I was looking at the Antarctic ice loss acceleration rate !

  5. According to Danas latest article the ice loss in Antarctica has trebled over the last decade...

  6. Snoopy, have you got a reference for your allegation?

  7. Re: Why the Vikings came and then left Greenland.  It is really quite simple. It was warm, there were very nice Birch forests, the glaciers were receding and everything was green.  The land was good for farming, so you could raise cattle, goats and other livestock. Because of local warming you could ship goods back and forth from Europe.  Then they got a cold snap that lasted a few hundred years.  You can't farm if your land turns to permafrost.  The sea started getting too much ice and too many storms.  In a nutshell, climate change drove them out. It was the same thing that happened in Northern Canada.  The camels and elephants (mastodons) could not find food anymore. Climate change wiped them out.

    Moderator Response:

    [DB]  There is so much wrong with your comment that it is difficult to know where to begin.  However, it is much warmer now than during the failed Viking occupation of Greenland.  That those Vikings who didn't die abandoned their settlements while the local Inuit thrived unabated to today is indicative that a changing climate was not an ultimate obstacle to habitation of Greenland.  For more information, see this post.  Please stay on-topic.

  8. Sorry Doug @7 , but it wasn't "climate change wiping them out".  The history was much more complex than that.  Other factors - geopolitical and local factors - were much larger than the minor climatic change.

    You can find more detailed discussion elsewhere on SkepticalScience.
