[DS/SG] More climate stuff

G'day guys,

Whilst battling a spout of insomnia I got to pondering climate for DS, SG
<as you do ;)> and wondered if the guys who'd played ice-terrain games
had taken into account sympathetic vibrations in the ice? That is if tracked
etc and not going < than (say) 10 then the ice sheet will shatter. One
example of this is when the Russians withdrew across the ice-lakes in
WWII and the the Germans belted in after them... fatal mistake, another is the
waves in the ice-sheet set-up when planes land on them in the Antarctic.

Anyways just wondering.
