The problem with many of these predictions is that climate is a very complex phenomenon. There are *natural* climatic cycles, the shorter of which have a duration on the order of centuries. Until we have a precise model of the *causes* of the natural cycles we have no way of telling whether a given trend is natural or man-made. Thus, even if the climate does begin to warm in the next century it may well just be the natural up side of the current cooling trend! Though by that time we will hopefully have the precise model necessary to tell the difference. --- Sarima (Stanley Friesen) UUCP: {ttidca|ihnp4|sdcrdcf|quad1|nrcvax|bellcore|logico}!psivax!friesen ARPA: ??
