For anyone who missed the programme and/or who wants to get a fuller
picture and better balance than this week's rather sensationalist
broadcast, the Horizon webpage is the place initially to go:

http://www.bbc.co.uk/science/horizon...bigchill.shtml

It makes it plain (if you look) that only *some* scientists currently
accept the "big chill" scenario but many more think we should at least
take seriously the possibility. Clearly, though, the "big chill" and
global warming are not mutually exclusive.
