  Heinz,
    Thanks for the update on future plans for the PAGES/CLIVAR intersection.
  Work on the paper is coming along slowly. I just need contributions
  from Keith and Tim here and Caspar at NCAR. I'm away July 16-28,
  so I hope that the final contributions will arrive whilst I'm away, just like
  Swiss trains - always on time!

    I've reminded Keith and Tim, so remember Swiss timing Caspar!

  Cheers
  Phil


  Cheers
  Phil
