...these two important links indicate in very clear terms that great difficulty lies ahead for those who would seek to have a more balanced and scientifically reasoned approach to dealing with this debate and to offer an alternative viewpoint.
This juggernaut will be difficult to stop, as the allure of what seems to be unlimited amounts of money being made available to those who have vested interests in seeing these measures adopted and consolidated, will be impossible to resist.
It's obvious that it must be stopped - but how?
..and that is a major worry, Zulu. In practical terms all commodities have an intrinsic value, which means that when an overinflated value falls, there is a cushion, at which the natural demand for a commodity prevents further fall. In this unique case, trading the right to emit CO2 has NO intrinisic value whatsoever. When all the major financial institutions pile into it, there will be a bubble - and that bubble will, sooner or later, burst. Because the right to emit CO2 has no value (it is, after all literally hot air), there will be no floor to cushion the blow and, quite possibly, trillions could be lost overnight. It would make the credit crunch look like a tea party.
