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
