subject: Another Reminder about your Wengen contribution


Keith, Tim, Caspar,
I will add in the ice core piece over the weekend. It was only
about 5pp of text with no figures, so it shouldn't take too long
for you to do your part!

Those that wrote the ice core piece didn't even have the nice
few days in Wengen!
