For the same reason we can't be sure that solar activity won't bring on a period of global cooling, as was widely predicted by scientists in the 70's. Regards, Platt Mark 20-02-07: Hi Platt, Thank you. I don't feel you have addressed my question. My question asks if technology may be enhancing TF. You state the direction of TF cannot be reliably predicted by science and site an example from the 70's. Points: 1. The 70's scientific prediction of global cooling is based on the same science you cite as criteria for accepting the validity of TF in the first place. You remind me TF is a valid empirical observation and then bring into question an extrapolation from the same empirical observations which display cyclic behaviour over geological time which may indicate we are over due for ice age conditions. Substituting the term, 'prediction' for 'extrapolation' may suggest science is on a par with astrology which i feel would be a mistake. 2. Therefore, science was and is correct in its extrapolations; the next ice age is over due but don't hold your breath because it may not even begin for thousands of years as observed in the geological cycles. 3. Non of this addresses my question unfortunately, because there is no previous data concerning the effects of an Industrialised Global civilisation to observe and extrapolate. 4. To sum up: a. My question concerns how we may deal with that which is as yet not fully understood. b. Your response deals with that which is fully understood. Please feel free to have another go Platt.
