Did anyone else watch this last night - what did you think of it?
Paul Hyett, Cheltenham

Yes, and I mostly enjoyed it.
I was intrigued by the proposition that the cause of the Ice Age was
the
land bridge between North and South America - that was news to me.

Well, I think the theory is when the Isthmus of Panama was open, water
could
circulate more easily around the equator picking up more heat and
enabling
more heat to be transported north and south. With it closed only the
Altantic's heat is available to our area, and the global circulation
around
the equator more broken up. So it cools?
Is that roughly it?
Peter Hearnden

Yes. It wasn't that I didn't follow or undersatnd what they were saying,
just that it was new to me g
