It strikes me from time to time that the human element is of a pretty arrogant type. How is it that we think that global warming is 100% of a human effort? The earth throughout it's history has gone through warming and cooling cycles. I do not dispute, as an engineer, that we need to use our brains to improve our technology to the point and benifit of all human kind and, at times certain sections of the race need to be blackmailed for their own good. But this constant arrogant trash which I suspect is being used by politics and business to further their own, short term, interests will eventually produce a backlash which will be of no use to anyone or at the least an attitude of indifference which will produce a cynical backlash. Can ayone run out the actual authoritive figures for this thing or not?
