Yes, �climate change� is the latest incarnation of �Global Warming�. It was introduced a while ago when scientists announced that, er, the earth was not warming up quite so quickly as previously forecast (because, as usual, they had extrapolated short term variations to determine long term changes). They decided that Global Warming had been postponed for about ten years and would not resume until about 2016. No matter, the scam must go on, so the term �Climate Change� was born.
The effect the forced use of these ridiculous devices will have upon climate change (real or imagined) is debatable. The assumptions made for their effect on the reduction in �carbon emissions� are somewhat simplistic. The calculations assume that because consumers reduce their demand on the power stations by using the new bulbs those stations will somehow be able to run at reduced output. This is patently absurd. Power stations run at a fairly constant output regardless of the load and the coal/gas/oil consumption does not reduce simply because somebody turns a light off in their home, ot changes a traditional bulb for a new one.
Of course, if it is being claimed that in the long term fewer power stations will be needed because we all switch to the new devices, that is a different matter. But as I understand it, that is not what is being claimed.
