Just my sixpence worth - Global warming is part of human consciousness which allows for speculation, possibility, probability and all the other things necessary for the ongoing speculation in order to try and understand our universe; not scientific or inevitable 'fact'. Human consciousness is part of the universe, rather than a mere observer of it, and in that guise it has been argued, it may be able to develop to the extent of altering the future physics of that universe - perhaps even to prevent what at the moment appears to be the inescapable death of our sun and home planet. The scientist Paul Davies, for example, has speculated along precisly those lines about the interaction of consciousness and matter: :..... there is still a sense in which the human mind and society may represent only an intermediate stage on the ladder of organisational progess in the cosmos. To borrow a phrase from Louise Young, the universe is as yet 'unfinished'. We find ourselves living at an epoch only a few billion years after creation. From what can be deduced about astronomical processes, the universe could remain fit for habitation for trillions of years, possibly forever." (Davies, Paul: The Cosmos Blueprint: Order and Complexity at the Edge of Chaos, Harmondsworth: Penguine, 1995; p.196) An unfinished universe then, still holds out possibilities, and is not necessarily to be regarded as a programme running inexorably and unchangably through to its pre-determined end.
